Ingredients
Scale
For the cake:
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup creamy peanut butter
- 1 cup granulated sugar
- 1/2 cup brown sugar
- 3 large eggs
- 1 teaspoon vanilla extract
- 1 cup whole milk
For the peanut butter frosting:
- 1/2 cup unsalted butter, softened
- 1/2 cup creamy peanut butter
- 2 cups powdered sugar
- 2–3 tablespoons milk
- 1/2 teaspoon vanilla extract
Instructions
- Preheat and prepare pan: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking dish to ensure the cake doesn’t stick.
- Mix dry ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt to evenly distribute the leavening agents and salt throughout the flour.
- Cream wet ingredients and sugars: In a large mixing bowl, cream together the softened butter, creamy peanut butter, granulated sugar, and brown sugar until the mixture is light and fluffy, which will help create a tender cake texture.
- Add eggs and vanilla: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Then mix in the vanilla extract to enhance the flavor.
- Combine wet and dry ingredients: Add the dry ingredients in three parts, alternating with the milk. Start and end with the flour mixture. Mix gently just until combined to avoid overworking the batter.
- Pour and bake: Pour the batter into the prepared baking dish and spread it evenly. Bake for 35–40 minutes or until a toothpick inserted in the center comes out clean.
- Cool the cake: Remove the cake from the oven and let it cool completely in the pan to room temperature before frosting, preventing the frosting from melting.
- Make the frosting: In a bowl, beat together the softened butter and peanut butter until smooth. Gradually add the powdered sugar. Mix in the vanilla extract and 2–3 tablespoons of milk, one tablespoon at a time, until you reach your desired frosting consistency.
- Frost the cake: Spread the frosting evenly over the cooled cake and slice into servings.
Notes
- Add chopped peanuts or chocolate chips to the batter for extra texture and flavor.
- Store the cake covered at room temperature for up to 3 days to maintain freshness.
- Refrigerate for longer freshness, and bring to room temperature before serving for best flavor and texture.
