Method
Preparation
- Preheat oven to 350°F (175°C). Prepare an 8x8 baking pan or two 6-inch cake pans by buttering them and lining with parchment paper.
- In a bowl, sift together the flour, cornstarch, baking powder, and salt. Set aside.
Mixing
- Cream together butter and sugar on medium-high speed until light and fluffy. Add in the whole egg, mix for a minute, then add the egg white and vanilla extract. Blend until smooth.
- On low speed, alternate adding the flour mixture and buttermilk until fully combined. Be careful not to overmix.
Baking
- Pour the batter into the prepared pan and bake for approximately 30 minutes. Check for doneness with a cake tester.
- Let the cake cool in the pan on a wire rack.
Frosting
- Beat butter for frosting on high for 5 minutes, add powdered sugar gradually, then blend in heavy cream and vanilla. Mix until fluffy.
Serving
- Decorate the cooled cake with frosting and serve. Enjoy with fresh berries or ice cream!
Notes
For richer flavor, consider browning the butter before creaming. Ensure butter and eggs are at room temperature for best results. For added texture, fold in chocolate chips before baking.
