If I have a bit more time, this is my favorite dessert to make. The recipe isn't hard but just a bit time consuming. There are two options with this cake, you can use raspberries or blueberries. If you can't find Meyer Lemons regular lemons will do. I have also given you two options for frosting, if you don't like cream cheese frosting you can use the Mascarpone Frosting which is a bit lighter.
1 cup sugar
3 eggs separated. Save yolks & whites.
2 cups all purpose flour
1 tablespoon baking powder
1 teaspoon salt
1/2 teaspoon baking soda
1 cup plain greek yogurt
1 Cup fresh raspberries
4 ounces cream cheese, room temperature
4 tablespoons unsalted butter, room temperature
zest & juice of 1 meyer lemon
pinch of salt
2 cups powdered sugar
Preheat your oven to 320F. Grease and line two 6" cake pans with parchment paper and set aside.
Cream the butter and sugar until light and fluffy. Add the egg yolks one at a time, mixing after each addition.
Add the flour, baking powder, salt, and baking soda and mix until mostly combined. Add the yogurt and mix until combined.
Beat the egg whites to medium peaks and fold into the cake batter. Gently fold in the raspberries with a rubber spoon.
Divide the batter evenly between the two pans and bake 25-30 minutes, or until a toothpick comes out clean. Keep an eye on it you don't want the cake to get to firm. Let the cakes cool in the pan for about 10 minutes before turning them out onto a wire rack to cool completely before icing.
For the buttercream, cream the cream cheese and butter until smooth. Add the lemon zest and juice and salt and mix until combined. Slowly add the powdered sugar and mix until combined. Mix on medium speed for a couple minutes until light and fluffy. If your buttercream is softer than you'd like, you can either add more sugar or chill it for 30 minutes.
To make a four layer cake, slice each cake layer in half. spread with buttercream and top with another cake layer. continue until all layers are used. spread the cake with remaining buttercream. Top with additional berries one top.
