I have not tried this yet. I plan to make it for Ostara/Easter. It will be getting streamlined by me as it appears to be very putsy.

Fresh Lemon Coconut Cake

Cake
2.5 cups cake flour
2 tsp. baking powder
1 tsp. salt
1 cup unsalted butter
softened
2 cups sugar
5 large eggs separated
2 tsp. grated lemon peel
2 tsp vanilla extract
1 cup sour cream

Heat oven to 350. Coat 2 9 x2 inch round cake pans with baking spray. In bowl mix up flour, baking powder and salt. In another bowl, beat butter until creamy. Add sugar beat 5 minutes until light and fluffy. Beat in egg yolks one at a time. Beat in lemon zest and juice and vanilla. On low speed beat in flour mixture with sour cream until combined. In yet another bowl with clean beaters(this is starting to sound like Martha Stewarts kitchen)beat the egg whites at high speed until stiff peaks form. Fold this into batter and spread in cake pans. Bake 32-34 minutes. Let cool in pans on wire racks 10 min and then turn cakes out.

Lemon Filling

Cover surface with plastic wrap; let cool. Place 1 cake layer on plate. Spread with filling then cover with other layer.

Fluffy Frosting
3 large egg whites
3/4 cup sugar
3 T water

1.5 cups coconut

In heatproof bowl mix all ingredients except extracts and coconut. Using mixer, beat 1 minute. Place bowl over pot of simmering water but not touching water.
