Ingredients
Scale
Cake
- 2 cups all-purpose flour
- 1 cup sugar
- 1 cup creamy peanut butter
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup buttermilk
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup unsalted butter, melted
Frosting
- 1 cup creamy peanut butter
- 4 cups powdered sugar
- 1/2 cup unsalted butter, softened
- 1/4 cup milk (adjust for consistency)
- 1 teaspoon vanilla extract
Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease a 9×13 inch sheet cake pan lightly with butter or non-stick spray and set aside.
- Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
- Combine Wet Ingredients: In another bowl, blend the peanut butter, melted butter, buttermilk, eggs, and vanilla extract until smooth and well incorporated.
- Form the Batter: Gradually add the dry ingredients to the wet, stirring gently until just combined. Avoid overmixing to keep the cake tender.
- Bake the Cake: Pour the batter into the prepared sheet pan and spread evenly. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Prepare the Frosting: While the cake cools, beat together the softened butter, peanut butter, vanilla extract, and powdered sugar. Add milk slowly to reach desired frosting consistency.
- Frost the Cake: Once the cake has completely cooled, spread the peanut butter frosting evenly over the top. Slice and serve.
Notes
- Make sure the cake is completely cool before frosting to prevent the frosting from melting.
- Use creamy peanut butter for smooth texture; natural peanut butter can be used but may affect consistency.
- For a richer flavor, substitute some of the all-purpose flour with whole wheat flour.
- Store the frosted cake covered at room temperature for up to 2 days or refrigerated up to 5 days.
- You can add chopped peanuts on top of the frosting for extra crunch.
