Step by Step Instructions

Start by making the blueberry filling. Use fresh or frozen berries. If you are using frozen, allow to thaw first. Combine blueberries, sugar, and lemon juice in a saucepan. Over a medium heat, allow to simmer. Cook until the berries are soft and the sauce thickens a bit. Use an immersion blender or you Vitamix to puree the blueberries. Return to sauce pan and simmer on low heat until thickened up and/or reduced by about 1/3. The blueberries will continue to thicken as they cool.

Lemon Cake: Preheat the oven to 325 degrees F. and grease cake pans. In a medium bowl combine flour, baking powder, and salt. Whisk gently. In a large bowl add sugar, eggs, lemon juice, sourdough discard, vanilla and almond extracts. Use a hand mixer to blend. In a pyrex measuring cup, heat milk, butter, and coconut oil until warm in the microwave (you may also use a saucepan to heat). Slowly pour into the egg and sugar mixer, blending with your hand mixer. Slowly mix in the dry ingredients. When all of the ingredients are incorporated, pour the cake mix evenly into your cake pans. Bake 30 – 40 minutes or until a toothpick in the center comes out clean. When the cake is one use a knife to loosen the sides of the cake from the pan. Allow to sit for about 20 minutes. Invert cake on to cooling rack and allow to cool completely prior to frosting.

Lemony Cream Cheese Frosting: Combine 3/4 cup butter and 1 cup of cream cheese, room temperature. Use a hand mixer to whip until blended. Slowly add 1 1/2 cups powdered sugar and 1 tablespoon of lemon juice. Mix until smooth and creamy.
