Cake With Custard Filling
This cake with custard filling is a light and tender white cake, filled with a lemon custard filling and topped with a simple whipped cream frosting. You can garnish with chocolate if you have it around, but no need for it to look and taste great.

- 1/4 teaspoon cream of tartar
- 1/4 cup granulated sugar
- 1/2 cup shortening
- 3/4 cup granulated sugar
- 1/2 cup sour cream or vanilla yogurt
- 1 tablespoon vanilla
- 1 tablespoon baking powder

Whipped Cream Frosting

- 1/2 cup shredded unsweetened coconut to garnish
Directions
Cakes
- Separate your egg whites and egg yolks into separate bowls. Keep 3 egg yolks which will be used in the custard. The remaining egg yolks can be discarded or saved for a stir fry, pasta or omelet in an airtight container in the fridge.
- With an electric mixer, whip the egg white on medium until foaming. Add cream of tartar.
- Add sugar slowly while beating and beat until the eggs and shiny stiff peaks. Set aside.
- In a new bowl beat shortening until creamy with electric mixer. Add sugar and continue to beat for 2 minutes.
- Add sour cream, vanilla and baking powder and beat for another minute.
- In a small bowl mix cornstarch and flour.
- To the shortening mix alternate adding cornstarch and milk until all combined.
- With a spatula, gently fold in egg whites until entirely combined.
- Line 2 - 9 inch pans with parchment and then grease with butter.
- Pour 1/3 of the batter into 1 pan, and 2/3 of the batter into the other pan.
- Preheat oven to 300 degress F and bake for 20-40 minutes until a toothpick in the center comes out clean.
- NOTE: the thin cake will cook much quicker than the thick cake so be sure to check it around 20 minutes.
- Slice around sides with a knife to unstick sides- then let cool for 5-10 minutes in the pan before flipping out onto a wire rack to cool. Cool completely before cutting or frosting.
- Only the thicker cake will be cut horizontally to make 2 layers.
- Lemon Custard
- In a medium saucepan, whisk together sugar and conrstarch. Add milk. Then add yolks, salt, and zest (saving the juice for later).
- Cook over medium heat, stirring constantly with a whisk, until thickened.
- Remove from heat and stir in lemon juice.
- Pour custard through a strainer into a bowl. Cover with plastic wrap so that the plastic directly touches the surface (to prevent a skin from forming on the top).
- Refrigerate until cool and ready to use.
Whipped Cream Frosting
- In a large chilled bowl, whip whipping cream until it just begins to thicken and become foamy.
- Add vanilla and sugar and whip until the consistency of a thick cream.
Assembly
- Place 1 cake layer onto a serving plate. Top with 1/2 the custard, and optionally (drizzle with some chocolate sauce).
- Top with 2nd cake layer, followed by more custard and chocolate sauce.
- Add the final cake layer and top with frosting, using an offset spatula to make smooth.
- Garnish with you choice of shredded coconut and chocolate drizzle or frosting (if you have it on hand.)
Enjoy!
