Preheat the oven to 350 F.
Combine the dry ingredients: In a mixing bowl, combine the almond flour, coconut flour, baking powder, and salt. Give it a quick stir to evenly distribute the dry ingredients.
Add Butter: Cut the cold butter into small pieces and add it to the dry ingredients. Use a pastry cutter or your fingers to work the butter into the flour mixture until it resembles coarse crumbs.
Add Eggs: Crack the eggs into the mixture and stir until everything comes together to form a dough. You may need to use your hands to knead it a bit, but don't overwork it.
Chill the Dough: Form the dough into a ball and wrap it in plastic wrap or clean dish towel. Let it chill in the refrigerator for at least 30 minutes. This helps the dough firm up and makes it easier to work with.
Roll Out the Crust: Once the dough has chilled, place it between two sheets of parchment paper. Roll it out into a circle that's about 1/4 inch thick. If it cracks a bit, don't worry; you can easily press it back together.
Transfer to Pie Dish: Carefully peel off the top layer of parchment paper and flip the crust into a pie dish. Gently press it into the dish, and use your fingers to shape the edges as desired.
Pre-Bake Crust: Prick the bottom of the crust with a fork to prevent it from puffing up during baking. Bake in the preheated oven for about 10-12 minutes until it's lightly golden.
Remove from oven and allow to cool.
