Ingredients List
Basic Cake Ingredients
- 2 ½ cups all-purpose flour
- 2 cups granulated sugar
- 1 cup unsalted butter, softened
- 4 large eggs
- 1 cup milk
- 2 ½ teaspoons baking powder
- 1 teaspoon vanilla extract
- 1 teaspoon salt
Frosting Ingredients
- 1 ½ cups unsalted butter, softened
- 5 cups powdered sugar
- ½ cup heavy cream
- 1 teaspoon vanilla extract
- Food coloring (optional)
Step-by-Step Instructions
- Prepare the Cake Batter: Preheat your oven to 350°F (175°C). In a large mixing bowl, cream together the softened butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the milk and vanilla.
- Mix Dry Ingredients: In a separate bowl, combine the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.
- Bake the Cake: Divide the batter evenly between prepared cake pans. Bake in the preheated oven for 30-45 minutes, or until a toothpick inserted in the center comes out clean. Allow to cool in the pans for 10 minutes before transferring to wire racks to cool completely.
- Make the Frosting: In a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar, mixing well. Pour in the heavy cream and vanilla, and beat until light and fluffy. Add food coloring if desired.
- Assemble and Decorate: Once the cakes are completely cooled, place one layer on a serving plate. Spread frosting on top, then add the second layer. Frost the top and sides of the cake, using a spatula or piping bag for decoration.
