<human>:  I'm trying to find a recipe for a three-layer cake. Do you know how to make one?
<bot>: Preheat oven to 350 degrees F (175 degrees C). 2 Grease and flour three 8-inch round cake pans.3 In a large bowl, beat 3 cups of all-purpose flour, 3 cups granulated sugar, 1 cup butter (or margarine), 1 cup of shortening and 6 eggs with an electric mixer on medium to high speed for about 3 minutes, until the mixture is creamy and fluffy. 4 Combine 1 and 1/2 teaspoons baking powder and 1 cup of milk, and add to the cake batter.5 Place batter into the three cake pans.6 Bake in preheated oven for 25 minutes, or until a toothpick inserted into the center of the cake comes out clean. 7 Cool cake layers in the pan for 5 minutes.8 Remove layers from pan and cool completely on a wire rack.9 When layers have cooled, spread your favorite frosting between each layer, and frost the entire cake. Enjoy!
