2 lb. Expressbake Breadmaker

Oster 2 lb. Expressbake Breadmaker CKSTBRTW20

The Oster 2 lb. Expressbake Breadmaker CKSTBRTW20 is a household automatic bread machine designed to mix, knead, rise, and bake bread in a removable bread pan. It offers 12 preset programs for preparing different types of bread, dough, jam, and baked products.

The machine supports 1 lb., 1.5 lb., and 2 lb. loaf size selections on applicable programs. Its Expressbake function can prepare a 1.5 lb. or 2 lb. loaf in approximately 58 minutes, while the standard Basic program takes approximately 3 hours and 25 minutes for a 2 lb. loaf.

The breadmaker features an LCD control panel, selectable crust settings, a programmable delay timer of up to 13 hours, a glass viewing window, and an automatic keep-warm function that operates for up to one hour after baking.

Its removable bread pan has a nonstick surface and uses a kneading blade to mix and develop dough. The supplied accessories include a measuring cup, measuring scoop, and kneading blade removal tool.

The appliance can also prepare dough for pizza, bagels, rolls, and pasta, along with jams and marmalades. Correct ingredient measurements, ingredient order, program selection, and routine cleaning are important for producing consistent results.

Technical Specifications

The available crust colors, loaf sizes, and timer options depend on the selected baking program. Certain programs use fixed settings.

What’s Included in the Box

The product diagram identifies the breadmaker and its removable accessories.

The kneading blade is supplied in a small plastic wrapping attached to the power cord. It must be removed from this packaging before first use.

Parts and Components

The Oster CKSTBRTW20 has ten primary components identified in its parts diagram.

Glass Viewing Window

The viewing window is positioned in the top lid.

It allows the kneading, rising, and baking process to be monitored without opening the breadmaker.

The lid should remain closed during baking because repeated opening can affect the bread’s final texture and browning.

Removable Bread Pan

The bread pan holds all ingredients throughout the automatic breadmaking process.

It can be lifted from the machine using its handle.

The pan has a nonstick surface, so metal utensils and abrasive cleaning tools must not be used.

Kneading Blade

The kneading blade fits onto the drive shaft inside the bread pan.

It mixes the ingredients and develops the dough during the kneading cycle.

The blade must be correctly installed before ingredients are added.

If the blade remains inside the finished loaf, the supplied removal tool can be used to extract it.

Control Panel and LCD Display

The control panel allows the required program, loaf size, crust color, and delay time to be selected.

The LCD displays the selected menu number and remaining program time.

During operation, the countdown indicates the time remaining until the selected cycle finishes.

Control Panel and Buttons Guide

The Oster CKSTBRTW20 uses a digital control panel with several operating buttons.

Menu Select Button

The Menu Select button is used to choose the type of bread or other preparation program.

Each program has a number from 1 to 12.

The selected menu number appears on the LCD.

Crust Color Button

The Crust Color button changes the selected crust setting.

Available selections include:

• Light
• Medium
• Dark
• Rapid, on supported programs

The display uses an arrow to identify the selected setting.

Rapid is available on the Basic, French, and Whole Wheat programs and reduces the total program time by approximately one hour.

Certain programs have fixed crust settings that cannot be changed.

Loaf Size Button

The Loaf Size button selects the intended bread size.

Available selections are 1 lb., 1.5 lb., and 2 lb. on applicable programs.

2. Remove the packaging.
3. Position the blade over the drive shaft inside the bread pan.
4. Fit the blade securely onto the shaft.

Step 5: Prepare the Ingredients

Measure the ingredients required for the selected recipe.

The manufacturer’s instructions recommend starting with fresh flour and yeast.

The bread pan should remain outside the breadmaker while the ingredients are being added.

Measuring Ingredients Correctly

Accurate ingredient measurements are essential for producing properly risen and baked bread.

Measuring Liquid Ingredients

Liquid ingredients must be measured using a suitable measuring cup with clearly marked cup or ounce measurements.

1. Pour the liquid into the measuring cup.
2. Place the measuring cup on a flat surface.
3. Check the measurement at eye level.
4. Confirm that the required quantity has been measured.

Measuring Dry Ingredients

Dry ingredients must be measured carefully and leveled.

1. Use a spoon to place the ingredient into the measuring cup.
2. Fill the cup to the required level.
3. Remove excess ingredient using the back of a knife or a spatula.

The measuring cup must not be used to scoop flour directly from its container because doing so can compress the flour and result in excess flour being added.

Correct Ingredient Order

Ingredients must be placed into the bread pan in the following order:

1. Liquid ingredients first
2. Dry ingredients second
3. Yeast last

The yeast must not come into direct contact with liquid while ingredients are being added.

A small well should be formed in the flour, and the yeast should be placed inside it.

Ingredient Temperature

Unless a recipe specifies otherwise, the manufacturer’s introductory instructions recommend ingredients at approximately 77–85°F.

Recipes with different temperature requirements must follow their specified values.

For Expressbake recipes, the water must be heated to 115–125°F and measured using a cooking thermometer.

How to Use the Oster CKSTBRTW20 Breadmaker

The following steps describe the general procedure for making bread using the automatic baking programs.

Step 1: Install the Kneading Blade

Make sure the kneading blade is securely attached to the shaft inside the bread pan.

Step 2: Add the Ingredients

Breadmaker Programs and Settings

The Oster CKSTBRTW20 includes 12 preset programs.

The duration depends on the selected program and, for applicable settings, the loaf size.

Complete Breadmaker Program Chart

The durations shown are the manufacturer’s approximate program times for the specified settings, including 2 lb. loaves where applicable.

Menu 1: Basic

The Basic program is suitable for standard bread recipes.

It mixes, kneads, rises, and bakes bread automatically.

This setting is recommended for the traditional white bread recipe and can also be used for recipes such as potato bread, oatmeal bread, raisin bread, and light rye bread.

The Basic program supports the Rapid setting.

Menu 2: French

The French program provides a longer process for kneading, rising, and baking.

It is intended for French-style bread with a heartier crust.

The manufacturer’s recipes include French countryside bread and Italian herb bread.

The Rapid setting is available.

Menu 3: Whole Wheat

The Whole Wheat program is designed for recipes containing more than 50% whole wheat flour.

It provides a longer rising time to accommodate whole grain dough.

Expressbake Instructions: How to Make Bread in 58 Minutes

The Expressbake function is designed to prepare bread in less than one hour.

It operates differently from the standard bread programs and requires specific ingredients and preparation conditions.

Important Expressbake Requirements

Why Expressbake Bread Is Different

Expressbake bread tends to have:

• A darker crust
• A thicker crust
• A shorter loaf height
• A denser texture
• Occasional cracks across the top of the crust

These characteristics result from the higher-temperature, shorter-duration baking process.

Yeast Requirements

Fast-rising yeast must be used.

Regular active dry yeast is not recommended for Expressbake because the finished loaf may be considerably shorter.

Water Temperature Requirements

The water must be between 115°F and 125°F.

A cooking thermometer must be used to measure the water temperature accurately.

Water that is too hot can kill the yeast, while cooler water may not activate it adequately.

Other Ingredient Requirements

All other ingredients, including flour, sugar, butter, and dry milk, should be at room temperature.

The correct salt quantity must be used.

The manufacturer recommends following its Expressbake recipe quantities for consistent results.

How to Start an Expressbake Cycle

1. Install the kneading blade in the bread pan.
2. Measure the required water at 115–125°F.
3. Add the water and remaining liquid ingredients.
4. Add the dry ingredients, excluding yeast.
5. Make a small well in the flour.
6. Add the fast-rising yeast to the well.
7. Snap the bread pan into the machine.
8. Close the lid.
9. Plug in the breadmaker.
10. Use Menu Select to choose Menu 5 for a 1.5 lb. loaf or Menu 6 for a 2 lb. loaf.
11. Press Start/Stop.
12. Allow the cycle to finish without opening the lid.

The program automatically mixes, rises, and bakes the bread.

Expressbake Cycle Stages

The bread is finished when the display reaches 0:00.

Removing Expressbake Bread

1. Use oven mitts to remove the bread pan.
2. Turn it upside down over a cooling rack.
3. Shake it gently to release the bread.
4. If the loaf is difficult to remove, allow it to cool in the pan for approximately five minutes.
5. Use the kneading blade removal tool if the blade remains inside the bread.
6. Allow the loaf to cool for 15 minutes before slicing.

Before another Expressbake loaf is prepared, the breadmaker must cool for 20 minutes with the lid open.

How to Use the 13-Hour Delay Timer

The Delay Timer allows bread to finish at a selected future time.

The timer can be adjusted for up to 13 hours, including the selected baking program.

Important Delay Timer Restrictions

The manufacturer recommends using recipes that have already produced successful results.

The Delay Timer must not be used with:

• Expressbake programs
• Recipes containing perishable ingredients such as eggs or milk

The delay timer includes both the waiting period and the breadmaking program duration.

Example of Delay Timer Calculation

If the current time is 8:00 AM and bread is required at 6:00 PM, the total time between those points is 10 hours.

The delay timer must be set to 10:00.

Breadmaking Tips and Best Practices

Use Fresh Ingredients

The manufacturer recommends fresh flour and yeast.

Old flour may have absorbed moisture or become excessively dry during storage.

Old yeast may not activate properly, resulting in bread that does not rise sufficiently.

How to Check Yeast Freshness

The manufacturer provides a simple yeast test.

1. Fill a cup with warm water.
2. Add 2 teaspoons of sugar and stir.
3. Sprinkle a few teaspoons of yeast over the water.
4. Allow the mixture to stand for approximately 15 minutes.

Fresh yeast should produce foam and a noticeable yeast aroma.

If neither develops, the yeast should be discarded.

Check the Dough During Kneading

The manufacturer recommends checking the dough’s consistency during the second kneading cycle.

A properly mixed dough ball should appear smooth and rounded and move around the bread pan without excessive sticking.

Dough Is Too Wet

If the dough looks sticky or resembles pancake batter:

1. Sprinkle in a tablespoon of flour.
2. Allow it to mix.
3. Check the consistency.
4. Repeat with small additions until the dough forms a smooth, rounded ball.

Dough Is Too Dry

If the dough looks flaky or the breadmaker begins making knocking sounds:

1. Add one teaspoon of water.
2. Allow the dough to mix.
3. Check its consistency.
4. Repeat carefully until a smooth, rounded dough ball forms.

Too much additional water must be avoided.

Baking at High Altitudes

The manufacturer provides adjustments for locations above approximately 3,000 feet.

At higher altitudes, dough can rise more quickly and flour may become drier.

Adjustments should be made gradually while checking the results.

Measurement Equivalency Chart

One tablespoon equals three teaspoons, and half a tablespoon equals 1½ teaspoons.

Frequently Asked Questions

1. How do I use the Oster CKSTBRTW20 Breadmaker?

The kneading blade must first be installed in the removable bread pan. Recipe ingredients are added with liquids first, dry ingredients second, and yeast last. After the pan is secured and the lid closed, the required program, loaf size, and crust color are selected. Pressing Start/Stop begins the automatic breadmaking cycle. When baking finishes, the breadmaker sounds 15 beeps and enters Keep Warm mode.

2. How many baking programs does the Oster CKSTBRTW20 have?

The breadmaker has 12 programs: Basic, French, Whole Wheat, Sweet, Expressbake 1.5 lb., Expressbake 2 lb., Quick, European, Dough, Bagel Dough, Jam, and Bake. Program durations range from approximately 58 minutes for Expressbake to 3 hours and 35 minutes for the standard 2 lb. French cycle.

3. How do I use Expressbake to make bread in 58 minutes?

Select Menu 5 for a 1.5 lb. loaf or Menu 6 for a 2 lb. loaf. Expressbake recipes require fast-rising yeast, bread flour, and water heated to 115–125°F. Ingredients must be loaded in the specified order, and the lid must remain closed throughout the cycle. The Delay Timer and Crust Color adjustments cannot be used with Expressbake.

4. How do I set the 13-hour delay timer on the Oster Breadmaker?

The ingredients must be loaded, and a compatible baking program selected. The Delay Timer Up or Down buttons are then used to select the total time until the bread should be finished. The timer adjusts in 10-minute increments and includes the baking cycle itself. Pressing Start/Stop activates the timer, and the colon on the LCD flashes. Expressbake programs and recipes containing perishable ingredients such as eggs or milk must not be used with the delay timer.

5. What do E00, E01, EEE, and HHH mean on the Oster Breadmaker?

E00 and E01 indicate that the internal baking chamber temperature is outside the permitted range, either above 136°F or below −4°F. The appliance should be allowed to return to room temperature before another attempt. EEE indicates a broken temperature sensor circuit, while HHH indicates a bypassed temperature sensor circuit. These sensor problems require authorized service.

6. Why does the Oster Breadmaker display 0:00 and keep beeping?

When a normal breadmaking cycle finishes, the display reaches 0:00 and the machine sounds 15 beeps. The appliance then enters Keep Warm mode, and the 0:00 display flashes. The warming function operates for up to one hour, after which another 15 beeps sound. Start/Stop may be pressed to cancel Keep Warm.

7. How do I remove and clean the kneading blade?

The breadmaker and bread pan must be allowed to cool. The kneading blade can then be removed from the pan and wiped using a damp cloth before being dried thoroughly. If it becomes stuck, warm water may be placed in the bread pan for 10–15 minutes to loosen it. The kneading blade and bread pan must not be cleaned in a dishwasher.

8. Why is my bread not rising properly in the Oster CKSTBRTW20?

Poor rising can result from old yeast, unsuitable flour, incorrect ingredient measurements, or missing ingredients. The manufacturer recommends using fresh flour and yeast and adding ingredients in the correct order. For ordinary recipes, liquids are added first, dry ingredients second, and yeast last. If the loaf rises too little, the recipe may require a small reduction in flour or an increase in yeast, with adjustments made gradually.
