Line an 8x8 baking pan with parchment paper. In a mixing bowl, stir together 1 cup peanut butter, maple syrup, coconut oil, vanilla extract, and sea salt until smooth.
1/3 cup maple syrup, 1/4 cup coconut oil, 2 tsp vanilla extract, 1/4 tsp sea salt
Stir in almond flour until a thick mixture is formed.
2 cups almond flour
Fold in 1/2 cup chocolate chips.
Press into the prepared baking pan in an even layer, and freeze while you prepare the chocolate layer.
In a microwave-safe bowl, add the remaining 1 cup of chocolate chips and 2 tbsp of peanut butter. Microwave in 30-second increments until melted and smooth when stirred. You can also use a double boiler.
Pour the melted chocolate over the peanut butter layer and spread evenly. Freeze for 1 hour.
Remove from the freezer, then slice into 16 squares. You can run the knife under hot water before slicing for a cleaner cut. Store in the fridge or freezer.
