Ingredients
  

For the Cake Base
  • 1.5 cups All-purpose flour
  • 1 cup Granulated sugar
  • 1 tsp Baking powder
  • 0.5 tsp Salt
  • 0.5 cup Unsalted butter, softened
  • 2 Large eggs
  • 0.5 cup Milk
For the Simple Buttercream Frosting
  • 1 cup Unsalted butter, softened
  • 3 cups Powdered sugar, sifted
  • 1 tsp Vanilla extract
  • 2 tbsp Heavy cream Add more if needed for consistency

Equipment

  • 6-inch round cake pans
  • Electric mixer
  • Offset spatula

Method
 

  1. Preheat your oven to 350°F (175°C). Grease and flour two 6-inch round cake pans.
  2. In a large bowl, whisk together the flour, sugar, baking powder, and salt for the cake base.
  3. Beat in the softened butter until the mixture resembles coarse crumbs. Add the eggs one at a time, mixing well after each addition.
  4. Gradually mix in the milk until the batter is smooth. Divide the batter evenly between the prepared pans.
  5. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before turning them out onto a wire rack to cool completely.
  6. To make the frosting, beat the softened butter until creamy. Gradually add the powdered sugar, mixing on low speed until combined. Add the vanilla extract and heavy cream. Beat on medium-high speed until light and fluffy.
  7. Once the cakes are completely cool, level the tops if necessary. Place one layer on a serving plate and spread a layer of frosting. Top with the second cake layer.
  8. Apply a thin crumb coat of frosting to the entire cake and chill for 15 minutes. Apply the final layer of frosting. Decorate simply with sprinkles, small piped borders, or fresh berries for a cute look.

Notes

For a cute design, consider using pastel food coloring in the buttercream. A simple design involves covering the cake in white frosting and adding a ring of small, colorful candy pearls around the base.
