Line two 8x8 pan with parchment paper, preheat your oven to 350 degrees F and set aside.
In a large mixing bowl, mix together your almond flour, coconut flour, salt, baking powder, sugar, and cocoa powder. Whisk until well combined.
Mix in your eggs and vanilla extract, whisk together until everything is smooth and combined. You should have a dough forming. Split into 2 equal parts.
Evenly spread one dough ball into the bottom of each of your prepared pans and bake for 8-12 minutes. If you only have one pan allow for the first cookie to cool before removing from the pan, and then repeat baking process with second half of dough. One will be the bottom and the other the top of the ice cream sandwich.
Place your cookies into the freezer and make your ice cream. Whisk together all of your ice cream ingredients and prepare according to your ice cream makers instructions.
In one 8x8 pan (still lined with parchment paper), with a baked cookie on the bottom of your pan, pour your finished ice cream on top of the bottom cookie layer and then carefully top with your cookie topper, be careful not to press it too far into the ice cream.
If you are using store bought ice cream, allow to thaw a bit and spread over your bottom cookie layer, top with your cookie topper and freeze.
Allow to freeze for 3-4 hours, cut into 8 equal pieces and enjoy!
