Ingredients
Cake
- 3/4 cup butter, softened
- 1 1/2 cups sugar
- 2 cups all-purpose flour
- 2 Tbsp cornstarch
- 1 Tbsp baking powder
- 3/4 tsp salt
- 3/4 cup + 2 Tbsp milk
- 2 Tbsp lemon juice
- 2 tsp vanilla extract
- 1/4 cup Greek yogurt or sour cream
- 5 egg whites
Filling
- Lemon Curd
Raspberry Buttercream
- 1/2 cup butter, softened
- 1/2-3/4 cups fresh raspberries
- 2-3 cups powdered sugar
- 1-2 Tbsp heavy cream
- salt to taste
Instructions
Cake
- Preheat oven to 350 degrees and line two 12-cup muffin pans (or a mini muffin tin).
- In a large bowl, cream butter until light and fluffy, about 1-2 minutes. Gradually add in sugar, 1/2 cup at a time, beating until well combined.
- In a separate bowl, sift together flour, cornstarch, baking powder, and salt. Set aside.
- In a small bowl, mix together milk, lemon juice, vanilla extract, and Greek yogurt.
- Alternately add dry and wet ingredients into the creamed butter mixture, beginning and ending with the dry ingredients. Stir until just combined.
- Beat egg white until they form stiff peaks. Gently fold egg whites into the cake batter.
- Pour batter into cake pans, dividing evenly between the two. Bake for 16-17 minutes, or until a cake tester comes out clean. For mini cupcakes, bake for 8-9 minutes, or until a cake tester comes out clean.
Filling
- Once the cakes have cooled, with a sharp knife, cut a circle/hole into the center of each cupcake to create a small pocket for the filling, about 1/2 inch deep. Spoon in some of the curd, just until each hole is filled, and top with the pieces of cupcake you removed.
Raspberry Buttercream
- For the frosting, beat butter until light and fluffy. Add in 2 cups of powdered sugar and mix until combined.
- Add in 1/2 cup raspberries, and beat (the raspberries will break up, turning your frosting nice and pink!)
- Add in 1 Tbsp heavy cream and a pinch of salt.
- If the frosting seems too thin, add in the other cup of powdered sugar. If it seems too thick, add in another Tbsp of heavy cream and/or 1/4 cup of raspberries until it reaches your desired consistency.
- Frost cupcakes and enjoy!
