Ingredients
- 2 cups all-purpose flour
All-purpose flour provides the structure for the cake. It absorbs moisture and gives the cake its light and fluffy texture, allowing it to rise properly during baking. - 1 ½ cups sugar
Sugar not only sweetens the cake but also helps to create a tender crumb by breaking down the gluten that's formed when flour is mixed with liquid. - 1 cup creamy peanut butter
Peanut butter adds a rich flavor and moistness to the cake. It's the star ingredient that infuses the entire dessert with a delicious nutty essence. - ½ cup unsalted butter, softened
Butter contributes to the cake's rich flavor and helps create a tender texture. It also aids in flavor enhancement and adds moisture. - 3 large eggs
Eggs provide structure, stability, and moisture. They act as a binding agent, ensuring all ingredients come together cohesively. - 1 cup milk
Milk adds moisture to the cake and helps dissolve the sugar, making for a smoother batter. It contributes to achieving the ideal cake consistency. - 2 teaspoons baking powder
Baking powder is a leavening agent that helps the cake rise. It reacts with moisture and heat, creating bubbles that lighten the cake's texture. - 1 teaspoon vanilla extract
Vanilla enhances all the flavors in the cake, providing a subtle aromatic quality that complements the peanut butter. - 1 cup unsweetened cocoa powder
Cocoa powder deepens the flavor profile of the cake, providing a rich chocolate undertone that marries well with peanut butter. - 3 cups powdered sugar
Powdered sugar gives sweetness to the frosting along with a smooth, creamy texture. It dissolves easily, creating a light, fluffy consistency. - ½ cup heavy cream
Heavy cream adds body and richness to the frosting, helping it to achieve a velvety, spreadable texture that holds its shape.
Directions & Preparation
Step 1: Preheat the oven to 350°F (175°C).
Preheating the oven is crucial for proper baking. It ensures that the cake begins to rise as soon as it’s placed in the oven, resulting in a light and fluffy structure.
Step 2: Grease and flour two 9-inch round cake pans.
Greasing and flouring the pans prevents the cake from sticking, making it easier to remove them once baked. This step also ensures that the cakes have a nice shape.
Step 3: In a large mixing bowl, combine flour, sugar, and baking powder.
Mixing the dry ingredients together allows for even distribution of the baking powder, ensuring that the cake rises uniformly. This is an essential step for a consistent texture.
Step 4: In another bowl, cream the butter and peanut butter until smooth.
Creaming together the butter and peanut butter incorporates air into the mixture, which is important for creating a light cake. It also blends the flavors beautifully.
Step 5: Add eggs one at a time, mixing well after each addition.
Incorporating the eggs gradually ensures they fully integrate into the batter. This is vital for the emulsification of the mixture, leading to a cohesive texture.
Step 6: Stir in the milk and vanilla extract until smooth.
This step adds moisture, which is key to the cake's tender texture. It also enhances the cake with flavor, ensuring every bite is delicious.
Step 7: Gradually add the dry ingredients to the wet ingredients.
Mixing the dry ingredients gradually prevents clumping and allows for better incorporation. Overmixing at this stage can lead to a dense cake, so mix until just combined.
Step 8: Divide the batter equally between the prepared pans.
Dividing the batter evenly ensures that both layers bake at the same rate and results in a perfectly balanced cake. Use a spatula to smooth the tops for even baking.
Step 9: Bake for 25-30 minutes or until a toothpick comes clean.
Testing for doneness with a toothpick is crucial to avoid overbaking. An overly dry cake will lose its moisture, making it less enjoyable.
Step 10: Allow the cakes to cool in the pans for 10 minutes before removing.
Cooling in the pans briefly allows the cakes to set, making them easier to remove without breaking. It also helps retain some moisture.
Step 11: Prepare the peanut butter frosting by beating the peanut butter and heavy cream together.
The frosting's creaminess comes from the heavy cream, which helps achieve the desired consistency. Beating them together aerates the mixture for a light texture.
Step 12: Gradually add powdered sugar until well incorporated.
Adding the powdered sugar gradually prevents a sugar cloud and helps create a smooth, homogenous frosting. This step is necessary for flavor and texture perfection.
Step 13: Once the cakes are completely cooled, frost between the layers and on the top and sides.
Frosting only once the cakes are cooled prevents melting and sliding. A generous layer in between adds moisture and flavor, making each slice even more enticing.
Step 14: Decorate with additional peanut butter if desired.
Adding a decorative touch with extra peanut butter or even chopped peanuts elevates the visual appeal. It gives the cake a homemade touch that adds to its charm.

Why Peanut Butter is the Star of this Cake
Peanut butter is not just an ingredient; it’s the soul of the cake. Its rich, creamy texture ensures that each bite is packed with flavor. The natural oils in peanut butter contribute moisture, making the cake incredibly tender. This nutty spread also offers a unique flavor profile that stands out, making the cake both satisfying and comforting.
The Importance of Properly Creaming Ingredients
Creaming the butter and peanut butter is a vital step in creating a light and fluffy cake. It incorporates air into the batter, which helps the cake rise beautifully during baking. Properly creamed butter also lends to the overall texture of the cake, which should be soft and moist. Skipping this step can result in a dense cake that lacks the desired lightness.
Frosting that Complements, Not Overpowers
The peanut butter frosting is designed to enhance the cake without overshadowing its flavor. Achieving the right consistency is key; it should be smooth and spreadable yet firm enough to hold its shape. This balance allows the frosting to contribute sweetness while letting the rich flavor of the peanut butter cake shine through, making for a harmonious dessert experience.
FAQs
What can I add to the cake for extra texture?
Consider incorporating chopped peanuts or chocolate chips into the batter for extra texture and flavor. These additions can enhance the cake’s interest without overwhelming its peanut butter essence.
Why did my cake turn out too dense?
A dense cake often results from overmixing after adding the dry ingredients or not enough air incorporated during the creaming process. Ensure to mix gently and stop once combined for the best results.
Could I use crunchy peanut butter instead?
Yes, using crunchy peanut butter will add delightful texture and a more robust peanut flavor to the cake. Just note that this will affect the cake's crumb slightly.
Is there a way to adjust the level of sweetness?
You can reduce the sugar slightly in the cake or frosting to match your preference. However, be cautious, as too little sugar can affect texture and moisture.
What temperature should the pet cream be when making frosting?
It's best to use room temperature cream for the frosting, as this will whisk easily into the peanut butter, leading to a smooth and airy texture.
How can I achieve a glossier frosting finish?
For a glossier finish, beat in a little more cream to your frosting, or add a small amount of corn syrup to enhance the shine and make it more spreadable.
