The Recipe How-To

“Take a bite into the rich chocolate cake and let the creamy coffee frosting melt in your mouth.”

Now that we have gone through the ingredients, I’ll take you on a step-by-step guide to create the best chocolate oatmeal cake you will ever taste, topped with the rich flavor of our coffee frosting. Make sure all your equipment is clean and ready; a little preparation beforehand goes a long way in ensuring that your cake will be perfect from start to finish.

Step 1: Mix the Dry Ingredients

In a large mixing bowl, mix together 2 cups of all-purpose flour, 1 ½ cups of quick-cooking oats, 1 cup of brown sugar, 1 cup of granulated sugar, 1 teaspoon salt, 2 teaspoons baking soda, and 1 cup of unsweetened cocoa powder. Combine them well so that everything is thoroughly mixed.

Step 2: Add Eggs and Margarine

Take another small mixing bowl and whisk together two large eggs. Then add 1 cup of warm water and a stick of margarine (8 tablespoons). Make sure the margarine is at room temperature to avoid lumps. Once this mixture is smooth, slowly pour it into the large mixing bowl with dry ingredients while continuously mixing until everything is completely combined.

Step 3: Add Boiling Water

Slowly pour in 2 cups of boiling water, and mix until everything is well incorporated. The mixture may seem runny at first but keep stirring until you achieve a cake batter-like consistency.

Step 4: Bake

Before adding the batter to your preferred baking pan, make sure to grease it with butter or margarine. Then pour in the batter evenly and bake it for about 35-40 minutes at 350°F or until toothpick test comes out clean.

Step 5: Make Coffee Frosting

While you’re waiting for your cake to bake, make the coffee frosting: In a small mixing bowl, mix 4 cups of confectioners’ sugar, ½ cup (1 stick) margarine (room temperature), and 2 teaspoons of vanilla extract until light and fluffy. Dissolve 1 teaspoon of instant coffee granules in half-and-half cream then pour it into the sugar mixture. Mix until everything is creamy and smooth.

Step 6: Let Cake Cool Down

Once your cake is done, let it cool down completely before frosting it. This will prevent the frosting from melting on the cake.

Step 7: Frost Your Cake

Spread the frosting over the cooled oatmeal cake with an offset spatula or butter knife. To make the frosting more intense, sprinkle some cocoa or espresso powder over it.

Follow these steps, and you’ll have yourself a richly flavoured and delicious looking chocolate oatmeal cake with coffee frosting that you can confidently show off to your friends and family!

Make-Ahead, Storing and Reheating

“This cake is perfect for any chocolate lover, coffee addict or anyone who loves a good dessert.”

What’s better than having a delicious oatmeal cake with coffee frosting ready to serve at any time? Taking this recipe to the next level, I’m excited to share with you tips on how to make this cake ahead of time, store it properly and even reheat it, without losing its flavor or texture.

If you’re planning to make this cake ahead of time, then fret not. The chocolate oatmeal cake with coffee frosting stores well in the fridge for a few days, and in the freezer for even longer. For best results, wrap the cooled cake tightly in plastic wrap and store it in a container or freezer bag until ready to enjoy.

When you’re ready to serve, thaw the frozen cake overnight in the refrigerator for best results; however, if you’re short on time, you can pop the frozen cake into the microwave for approximately 20-30 seconds on medium heat. Alternatively, you can bake the thawed cake at 350°F degrees for about 5-8 minutes or until warm.

Storing frosted oatmeal cakes is quite tricky, but fret not! You can store it at room temperature if you plan to eat it within one day. If you want to store it for a longer period, then refrigerate it instead.

Another important tip is that while storing your frosted cake, wrap each slice individually in plastic wrap and then place them all together in an airtight container. This will prevent them from drying out and prolong their shelf life until you’re ready to eat them.

With these tips on how to store and reheat your chocolate oatmeal cake with coffee frosting, you’ll never have to throw away an uneaten slice again. Whether it’s cold from the refrigerator or warmed up in the oven or microwave – every bite will be just as mouth-watering and delicious as fresh out of the oven.

Tips for Perfect Results

“Impress your friends and family with this easy-to-make yet impressive chocolate oatmeal cake.”

Now that you’ve got the recipe for the drool-worthy chocolate oatmeal cake with coffee frosting, let me give you some tips to help ensure perfect results every time you make it.

Firstly, make sure that all of your ingredients are at room temperature before you start baking. This includes butter, eggs and half-and-half cream. This will ensure that your ingredients will blend together easily and create a smooth batter.

When adding the boiling water to the oats mixture, use caution to mix it slowly to prevent the hot water from splattering on you. Then let the mixture stand for at least 15 minutes, giving the oats enough time to fully absorb the water. This is crucial in ensuring a moist cake with a tender crumb.

For extra chocolate flavor in your cake, add some semisweet chocolate chips or cocoa powder to the batter before baking. If you’re feeling adventurous, feel free to try other flavor combinations such as dark chocolate chip or even coconut topping for added texture.

When it comes to making the coffee frosting, try using espresso powder instead of instant coffee granules for an even stronger coffee flavor. If you prefer a fudge frosting instead of buttercream, simply add more confectioners’ sugar and semi sweet chocolate chips until the consistency is thick enough.

Lastly, do not over-bake your cake! Check on it periodically starting at around the 30-minute mark until a toothpick comes out clean when inserted into the center of the cake. Over-baking can result in a dry and crumbly cake, ruining all your hard work.

By following these tips, you’ll have everyone thinking that you’re a professional baker with numerous years of experience under your belt!
