Ingredients

• 2.5 cups All-purpose flour
• 2 teaspoons Baking powder
• 0.5 teaspoons Salt
• 1 cup Unsalted butter (softened)
• 1.75 cups Granulated sugar
• 4 Large eggs
• 2 teaspoons Pure vanilla extract
• 1 cup Whole milk
• 0.25 cup Unsweetened cocoa powder
• 3 tablespoons Boiling water
• 1 cup Butter (softened, for frosting)
• 4 cups Powdered sugar
• 3 tablespoons Milk (for frosting)
• 1.5 teaspoons Vanilla extract (for frosting)
• 0 Food coloring (optional, for decorating)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans. Line the bottoms with parchment paper for easy release.

Step 2

In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

Step 3

Using a stand mixer or hand mixer, beat the butter and sugar together in a large bowl until creamy and fluffy, about 3-4 minutes.

Step 4

Add the eggs one at a time, mixing well after each addition, then mix in the vanilla extract.

Step 5

Gradually add the dry ingredients to the wet ingredients, alternating with the milk. Begin and end with the dry ingredients, mixing just until combined.

Step 6

In a small bowl, whisk the cocoa powder and boiling water together until smooth to create a chocolate paste.

Step 7

Divide the cake batter evenly between two bowls. Mix the chocolate paste into one bowl of batter to create the chocolate layer, leaving the second bowl as vanilla batter.

Step 8

Add dollops of vanilla and chocolate batter into the prepared cake pans, alternating between the two. Use a knife or skewer to gently swirl the batters together to create the marble effect. Be careful not to overmix.

Step 9

Bake the cakes for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.

Step 10

To make the frosting, beat the softened butter in a large bowl until smooth and creamy. Gradually add the powdered sugar, 1 cup at a time, mixing on low until the sugar is incorporated.

Step 11

Add the milk and vanilla extract to the frosting and beat on high until light and fluffy, about 3 minutes. Add food coloring if desired.

Step 12

Once the cakes are completely cool, frost the top of one layer, then place the second layer on top. Frost the top and sides of the cake evenly.

Step 13

Decorate the cake as desired. Slice and serve to enjoy!
