                Heat the oven to 350°F (175°C). Coat two 9-inch round pans with a light layer of grease and a dusting of flour.

                In a big bowl, stir together baking powder, flour, sugar, salt, cocoa powder, and baking soda until well blended.

                Pour eggs, oil, milk, and vanilla into the dry ingredients. Blend until smooth. Slowly stir in boiling water—it’ll be runny.

                Split the mix between the pans. Bake for 30-35 minutes or until a skewer poked in the middle comes out dry.

                After baking, let the cakes rest in the pans for about 10 minutes. Move them to cooling racks until fully cool.

                Whip up the butter until it’s nice and creamy. Gradually add cocoa and powdered sugar. Alternate adding milk and vanilla while beating until fluffy.

                Spread frosting over the first layer. Place the second layer on top and cover everything with frosting. Slice and enjoy.
