HOW TO MAKE IT :
CAKE
- Preheat the oven to 350°F. Prepare an 8-inch square pan with butter and flour or baking spray.
- Beat the butter at medium speed with a handheld mixer until creamy, roughly 3-4 minutes.
- Gradually add the sugar, beating until light and fluffy.
- Sift together the flour, corn starch, and baking powder.
- Add the flour mixture to the butter mixture alternately with the milk, beginning and ending with the flour mixture. Beat at a low speed just until blended after each addition.
- In a separate bowl, beat the eggs with a fork and then gently fold the beaten eggs into batter. Pour batter into prepared pan.
- Bake for 35-38 minutes, or until a toothpick inserted in the center of the cake comes out clean.
- Let the cake cool before adding the frosting.
SALTED CARAMEL BUTTERCREAM
- Combine the butter, sugar, salt, and caramel topping in the bowl of a stand mixer fitted with a paddle attachment.
- Start mixing on low speed until the sugar is incorporated with the butter.
- Increase the mixing speed to high and beat until smooth and fluffy (about 2 minutes).
- Adjust the consistency with milk, as needed.
- Frost the cake with the buttercream after the cake has cooled completely.
