Ingredients

1 ½ cups all-purpose flour
1 cup granulated sugar
½ cup unsweetened cocoa powder
1 teaspoon baking powder
½ teaspoon baking soda
½ teaspoon salt
½ cup unsalted butter, softened
2 large eggs
1 cup milk
1 teaspoon vanilla extract
1 cup creamy peanut butter
2 cups mini marshmallows
1 cup powdered sugar
1 teaspoon vanilla extract (for frosting)
Chocolate shavings or additional marshmallows for garnish (optional)

Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
Combine Wet Ingredients: In another bowl, beat the softened butter until creamy. Add the eggs, milk, and vanilla extract, mixing until well combined.
Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, mixing until just combined. Do not overmix.
Bake the Cakes: Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring to wire racks to cool completely.
Prepare the Frosting: In a large bowl, beat the peanut butter until smooth. Gradually add the powdered sugar and vanilla extract, mixing until creamy. Fold in the mini marshmallows.
Assemble the Cake: Once the cakes are completely cool, place one layer on a serving plate. Spread a generous amount of the marshmallow frosting on top, then place the second layer on top and frost the top and sides of the cake.
Garnish: Optionally, decorate the cake with chocolate shavings or additional marshmallows before serving.
