Mix butter and powdered sugar together, then add almond flour, flour and egg. Knead with hands until it forms a dough.
Roll dough out on a floured surface, then transfer dough to a greased baking dish. Trim excess dough, and pierce the bottom of the crust with a fork in several places. Add parchment paper and baking beans to weigh down the crust. Bake for 15 minutes at 375°F.
Pour caramel sauce over the crust, then sprinkle with peanuts and top with melted chocolate.
Refrigerate for 30 minutes, or until set. Slice, serve and enjoy!
