Ingredients:
- 1 1/2 cups all-purpose flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1/2 cup unsalted butter, softened to room temperature
- 1/2 cup creamy peanut butter
- 1 cup granulated sugar
- 2 large eggs
- 1 tsp vanilla extract
- 1/2 cup buttermilk
- 1 cup M&M’s (plain milk chocolate variety works best for even distribution)
- 1/2 cup unsalted butter, softened to room temperature (for frosting)
- 1 cup creamy peanut butter (for frosting)
- 2 cups powdered sugar (for frosting)
- 1/4 cup heavy cream (for frosting)
Preparing the Peanut Butter Cake Batter
Now that we have all our ingredients gathered, let’s get started on creating this wonderfully moist and flavorful Peanut Butter Cake. The key to a tender cake is ensuring your butter and eggs are at room temperature, which allows them to emulsify properly, creating a lighter texture.
Step 1: Combine Dry Ingredients
In a medium-sized bowl, whisk together the 1 1/2 cups of all-purpose flour, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt. Whisking these dry ingredients ensures that the leavening agents (baking powder and soda) and salt are evenly distributed throughout the flour. This will help your cake rise evenly and prevent any pockets of saltiness. Set this bowl aside.
Step 2: Cream Butter, Peanut Butter, and Sugar
In a separate, larger bowl, cream together the 1/2 cup of softened unsalted butter and the 1/2 cup of creamy peanut butter. You can use an electric mixer on medium speed, or a sturdy whisk and some elbow grease. Beat them until they are light and fluffy, which usually takes about 2-3 minutes with a mixer. This process incorporates air into the mixture, which is crucial for the cake’s texture. Once creamy, gradually add the 1 cup of granulated sugar to the butter and peanut butter mixture. Continue to beat until the mixture is pnon-alcoholic ale and fluffy, resembling a smooth, thick paste. This stage is called creaming, and it’s vital for the cake’s structure and moisture.
Step 3: Incorporate Eggs and Vanilla
Add the 2 large eggs, one at a time, to the creamed butter, peanut butter, and sugar mixture. Beat well after each addition to ensure the egg is fully incorporated before adding the next. This helps to create a stable emulsion. Next, stir in the 1 teaspoon of vanilla extract. Vanilla extract enhances the overall flavor profile of the cake and complements the peanut butter beautifully. Make sure to scrape down the sides of the bowl with a spatula periodically to ensure everything is thoroughly combined.
Step 4: Alternately Add Dry and Wet Ingredients
Now, we’ll start adding the dry ingredients and the buttermilk to the wet ingredients. This method, known as alternating, helps to prevent overmixing the flour, which can lead to a tough cake. Begin extract by adding about one-third of the dry ingredient mixture to the wet ingredients and mix on low speed (or stir gently by hand) until just combined. Then, add half of the 1/2 cup of buttermilk and mix until just combined. Repeat this process: add another third of the dry ingredients, mix, then add the remaining buttermilk, mix. Finally, add the last portion of the dry ingredients and mix until just incorporated. Be careful not to overmix at this stage. A few small lumps are perfectly acceptable. Overmixing develops the gluten in the flour too much, resulting in a dense and chewy cake rather than a light and tender one.
Step 5: Fold in the M&M’s and Bake
Gently fold in the 1 cup of M&M’s into the cake batter using a spatula. Distribute them evenly throughout the batter, trying not to crush them. This step is purely for fun and delicious bursts of chocolatey goodness within your Peanut Butter Cake. Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line it with parchment paper. Pour the batter evenly into the prepared pan. Bake for 30-35 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean. The cake should be golden brown around the edges and slightly springy to the touch. Let the cake cool in the pan for about 10-15 minutes before inverting it onto a wire rack to cool completely. This allows the cake to firm up, making it easier to handle.
Creating the Creamy Peanut Butter Frosting
While your cake is cooling, it’s time to whip up the decadent frosting that will crown your masterpiece. This frosting is incredibly simple yet delivers a punch of peanut butter flavor that pairs perfectly with the cake.
Step 6: Mix Frosting Ingredients
In a medium bowl, cream together the 1/2 cup of softened unsalted butter and the 1 cup of creamy peanut butter. Beat them until smooth and well combined. Gradually add the 2 cups of powdered sugar, a cup at a time, mixing well after each addition. The mixture will become quite thick. Finally, add the 1/4 cup of heavy cream and beat until the frosting is light, fluffy, and spreadable. If the frosting seems too thick, you can add another tablespoon of heavy cream, a teaspoon at a time, until you reach your desired consistency. If it seems too thin, add a little more powdered sugar. Once the cake has completely cooled, spread the frosting generously over the top and sides.
