1/2cuplemon curd**
Optional for decorating: edible sugar pearls or fresh berries and lemon zest
Instructions
Make the cake:
Heat oven to 350 degrees. Butter two 9-inch cake pans, line the bottoms with parchment paper and lightly butter the tops of the parchment.
Using a mixer on medium speed, cream the butter and sugar until light - a full 3 minutes. Add eggs, one at a time, mixing well after each. Add lemon zest, juice, and extract or oil (if using) - mix until smooth.
Add the flour, baking powder, and salt. Mix on low just until combined. Pour evenly into prepared pans, smoothing tops.
Bake 25 - 30 minutes, until a toothpick inserted in the middle of the cakes comes out clean. Remove from oven and cool 10 minutes on a rack.
Loosen edges with a knife and invert onto a cooling rack, remove parchment paper, and then turn right-side-up onto another cooling rack. Cool completely.
Make the frosting:
Cream the butter and lemon curd in the bowl of a mixer fitted with a whipping attachment. Add the powdered sugar a cup at a time.
After all the sugar has been added, add 1 tablespoon of milk and whip the frosting on high for a minute. Check the spreading consistency. If it seems thick, add another tablespoon of milk and whip again on high for a minute. TIP: The key to a light and airy frosting is whipping air into it, so keep whipping until it is very light and easy to spread.
Assemble the cake:
Cut the cake layers in half to make four layers (optional: do not cut and use just two layers, filling only one layer with jam).
For four layers: Place one layer on a cake plate and spread with 1/2 cup of jam. Place second layer on top and spread this layer with 1/2 cup lemon curd (or more jam). Repeat with third layer, spreading with another 1/2 cup of jam and then top with remaining layer of cake.
Frost the sides of the cake with the lemon frosting, swirling the frosting with a knife. Finish by frosting the top, using the remaining frosting. Sprinkle with decorative, edible sugar pearls or a mound of fresh berries sprinkled with lemon zest, if desired.
