BEHIND THE RECIPE
Besides the flavor and texture, this cake is loved is because of its ease. Very basic ingredients including a base of creamed butter + sugar, eggs, lemon, buttermilk, and flour. I love the additional tang buttermilk gives the cake, but you can use whole milk or 2% milk instead. I left out the brown sugar and replaced with more granulated sugar. No rhyme or reason here– just didn’t feel like reaching for both types of sugar this time. Between the cake and frosting, you’ll need 2-3 lemons. Both the juice and zest.
2 c all purpose flour
2 t. baking powder
1 t. salt
1/2 c butter
1 1/4 c sugar
1/4 c fresh lemon juice & 1 t. grated lemon zest
3/4 c milk

1 tablespoon grated lemon zest
1/2 c fresh lemon juice
1 t. cornstarch
6 t. butter
3/4 c sugar
4 egg yolks,beaten

1 t. grated lemon zest
1/2 c butter,softened
2 tablespoons fresh lemon juice
1 t. grated lemon zest
(add a couple drops of yellow food coloring if desired)
2 tablespoons milk (f needed to thin frosting)
1. Preheat oven to 350 degrees. Grease and flour two 8 inch round pans. Mix together the dry ingredientsSet aside. In a large bowl, cream together the butter and sugar until light and fluffy. Add lemon juice & zest to the milk.Beat in the eggs one at a time,stir in vanilla. Beat in the flour mixture alternately with milk, mixing just until incorporated. Pour batter into pans. Bake in the preheated oven for 30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool in pans on wire racks for 10 minutes. Then invert onto wire racks to cool completely.
2. To make filling: In medium saucepan, mix together 1 tablespoon lemon zest, 1/2 cup lemon juice and 1 tablespoon cornstarch until smooth. Mix in 6 tablespoons butter and 3/4 cup sugar, and bring mixture to boil over medium heat. Boil for one minute, stirring constantly. In small bowl, with a wire whisk, beat egg yolks until smooth. Whisk in a small amount of the hot lemon mixture. Pour the egg mixture into the sauce pan, beating the hot lemon mixture rapidly. Reduce heat to low; cook, stirring constantly, 5 minutes, or until thick (not to boil). Pour mixture into medium bowl. Press plastic wrap onto surface to keep skin from forming as it cools. Cool to room temperature. Refrigerate 3 hours.
3. To make frosting: In large bowl, beat confectioners’ sugar, 1/2 cup butter, 2 tablespoons lemon juice and 1 teaspoon lemon zest until smooth, and increase speed and continue to beat until light and fluffy.((add milk 1 tablespoon at a time to thin frosting if needed))
4. To assemble: With long serrated knife, split each cake layer in half horizontally, making 4 layers. Place 1 layer, cut side up, on a serving plate. Spread with half of the lemon filling. Top with another layer, and spread with 1/2 cup frosting. Add third layer, and spread with remaining half of the lemon filling.
