Ingredients:
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened to room temperature
- 1/2 cup creamy peanut butter
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup buttermilk
- 1 cup M&M’s (any variety you prefer, milk chocolate is classic)
- 1/2 cup unsalted butter, softened to room temperature (for frosting)
- 1 cup creamy peanut butter (for frosting)
- 2 cups powdered sugar, sifted
- 1/4 cup heavy cream (for frosting)
Preparing the Cake Batter
Dry Ingredients Assembly
First, let’s get our dry ingredients ready for the Peanut Butter Cake. In a medium-sized bowl, I like to whisk together the all-purpose flour, baking powder, baking soda, and salt. Whisking them ensures that all the leavening agents and salt are evenly distributed throughout the flour, which is crucial for a consistent rise and flavor in your cake. Set this bowl aside.
Creaming the Butter and Peanut Butter Base
Now, let’s move on to the wet ingredients that will form the heart of our Peanut Butter Cake’s rich flavor. In a large mixing bowl, cream together the softened unsalted butter and the creamy peanut butter. You want to beat these until they are light and fluffy. This process, called creaming, incorporates air into the mixture, which contributes to the cake’s tender texture. Using room-temperature butter is essential here; if it’s too cold, it won’t cream properly, and if it’s too melted, it can make the cake greasy. I usually use an electric mixer for this step, starting on a low speed and gradually increasing it.
Adding Sugar and Eggs
Once the butter and peanut butter are beautifully creamed, gradually add the granulated sugar. Continue beating until the mixture is pnon-alcoholic ale and well combined. Next, I add the large eggs, one at a time, beating well after each addition. It’s important to make sure each egg is fully incorporated before adding the next to prevent the batter from separating. Finally, stir in the vanilla extract for that classic, comforting aroma and taste.
Incorporating Wet and Dry Ingredients Alternately
This is where we bring everything together for our Peanut Butter Cake. Now, we’ll alternate adding the dry ingredients and the buttermilk to the wet mixture. Begin extract by adding about a third of the dry ingredients to the bowl and mixing on low speed until just combined. Then, add half of the buttermilk and mix again until incorporated. Repeat this process: another third of the dry ingredients, the remaining buttermilk, and finally, the last portion of the dry ingredients. Be careful not to overmix the batter once the flour is added. Overmixing can develop the gluten too much, resulting in a tough cake. Stop mixing as soon as you no longer see streaks of dry flour. A few small lumps are perfectly fine.
Folding in the M&M’s
For a fun pop of color and extra texture in your Peanut Butter Cake, gently fold in the M&M’s. Use a spatula and fold them in just until they are evenly distributed throughout the batter. I like to reserve a few M&M’s to sprinkle on top of the batter before baking for an extra decorative touch and a delightful surprise in every bite.
Baking the Peanut Butter Cake
Pour the batter evenly into your prepared baking pan. I usually bake this in a 9-inch round cake pan that has been greased and floured, or lined with parchment paper. Bake in a preheated oven at 350°F (175°C) for approximately 30-35 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for about 10-15 minutes before inverting it onto a wire rack to cool completely. It’s essential for the cake to be entirely cool before frosting, otherwise, the frosting will melt and slide right off.
Crafting the Creamy Peanut Butter Frosting
While the cake is cooling, let’s prepare the irresistible frosting for our Peanut Butter Cake. In a clean mixing bowl, cream together the softened unsalted butter and the creamy peanut butter until smooth and well combined. Gradually beat in the sifted powdered sugar, a little at a time, until fully incorporated. The mixture will likely be quite thick at this stage.
Achieving the Perfect Frosting Consistency
To achieve the perfect creamy consistency for the frosting, gradually add the heavy cream, one tablespoon at a time, beating after each addition. Continue adding cream and beating until the frosting reaches your desired spreading consistency. You want it to be smooth, creamy, and spreadable but not too thin. If it becomes too thin, you can add a little more powdered sugar, a tablespoon at a time. If it’s too thick, add a tiny bit more cream. Once you have the perfect texture, spread the frosting generously over the cooled Peanut Butter Cake. You can use an offset spatula for a smooth finish or create swirls for a more rustic look.

Frequently Asked Questions:
Can I make this Peanut Butter Cake ahead of time?
Yes, absolutely! This Peanut Butter Cake can be baked a day in advance and stored at room temperature in an airtight container. If you’re frosting it, it’s generally best to frost it closer to serving time, especially if using a cream cheese frosting, which benefits from refrigeration.
What’s the best way to store leftover Peanut Butter Cake?
To keep your Peanut Butter Cake fresh and moist, store any leftovers in an airtight container at room temperature for up to 3 days. If it’s been frosted with a dairy-based frosting, it’s best to refrigerate it and bring it back to room temperature before serving.
