Ingredients
Method
- Combine the egg yolks, whole egg, sugar, lemon zest, lemon juice, and salt in the top of a double boiler over gently simmering water. Whisk continuously until thickened and the mixture reaches 160°F. Remove from heat and whisk in the softened butter until smooth. Press plastic wrap directly onto the surface and chill until completely cooled.
- Preheat the oven to 350°F. Grease three 6-inch cake pans, line with parchment circles, and lightly grease again.
- Whisk together the flour, baking powder, and salt in a mixing bowl until evenly combined.
- Beat the butter and sugar until light and fluffy. Blend in the citrus zest, then mix in the eggs and vanilla until smooth.
- Add half of the dry ingredients along with half of the milk and citrus juice. Mix gently, then add the remaining dry ingredients, milk, and juice. Stir only until combined.
- Divide the batter evenly among the prepared pans and smooth the tops. Tap the pans lightly on the counter to release air bubbles.
- Bake until the centers spring back and a tester comes out clean, about 18–21 minutes.
- Cool the cakes in their pans for 30 minutes before transferring them to a wire rack. Allow them to cool completely before decorating.
- Beat the cream cheese until creamy. Add powdered sugar and vanilla, mixing until completely smooth. Slowly stream in the cold cream while mixing, then whip until stiff peaks form.
- Transfer about 1 cup of frosting to a separate bowl and fold in 3 heaping tablespoons of chilled lemon curd to create the filling.
- Place one cake layer on a serving plate and spread half of the lemon filling over the top. Add the second layer and spread with the remaining filling. Finish with the final cake layer.
- Spread a thin coat of plain frosting over the entire cake to trap crumbs. Refrigerate for 30 minutes until firm.
- Cover the chilled cake with the remaining frosting and smooth as desired. Chill again for at least 30 minutes before serving.
- Garnish with citrus slices if desired, then slice and serve.
