Start by making the chocolate sandwich layer. Combine the vanilla, maple syrup and melted coconut oil together. Then add the almond flour, coconut flour and sea salt to the wet mixture. Mix until it becomes a dough.
Place a piece of parchment paper on top of a large rectangular cutting board or cooking sheet. Spread the dough on top of the parchment paper lined cutting board/cooking sheet.
Place another piece of parchment paper on top of the dough and using a rolling pin, (wine bottle or any glass bottle!) roll the dough until it is flat and about 1/4 inch thick. The goal is to roll it out into a rectangular shape. Cut and roll to make it a large rectangle.
Place the rectangle shaped dough in the freezer while you make the "nice cream".
To make the "nice cream", place the sliced frozen bananas in a food processor or blender along with the vanilla, and sea salt. Blend until it is a smooth creamy, ice cream consistency. You will need to stop and scrape down the sides often to ensure it blends properly! If needed, add 1-2 tbsp of almond milk to help it blend.
Remove the dough from the freezer and slice the rectangle in half so there are two squares of dough.
Working quickly so the "nice cream" doesn't melt, spread it evenly on top of one layer of dough. Place the other layer of dough on top of the "nice cream" and freeze for about 2 hours.
Once the "nice cream" layer has frozen, remove from freezer and slice into about 8 rectangular sandwiches. You can stop here, but I love dipping each sandwich into melted chocolate chips and sprinkling with mini chocolate chips and/or sprinkles! Store in the freezer ad ENJOY!
