COOKIE CRUST
Preheat oven to 350 degrees F.
Mix butter with a hand mixer or the paddle attachment of a stand mixer for about 30 seconds, until soft and creamy.
Add sour cream and mix until smooth.
Add oil, egg yolk, oil, sugar, and almond and vanilla extracts.
Mix on medium-low until well combined.
Using the stir, scoop, and level method, measure gluten free flour into the bowl.
Add baking powder and salt and mix on low just until the dough comes together and is smooth and combined throughout.
Spread dough onto a 12 inch pizza pan (be sure it isn’t one with holes).
Bake for 13 minutes, be sure not to overbake! It will not brown, you just don’t want it to be doughy. You can press it lightly with your finger or use a toothpick.
Cool completely before frosting.
FROSTING
To make the frosting, mix cream cheese with a hand mixer or the paddle attachment of a KitchenAid mixer for 1-2 minutes, until smooth.
Add butter and sour cream and mix just until combined.
Mix in powdered sugar and lemon juice on low speed until smooth and creamy.
Spread frosting evenly over the cookie crust, leaving a little empty space around the edges.
You will have some frosting left over (it's great as a fruit dip or spread on gf grahams!)
Arrange the fruit on top, slice, and serve.
