Prep: First, line an 8x8 square baking pan with parchment paper.
Make Dough: Next, in a medium bowl, mix the peanut butter and maple syrup. Stir in the almond flour until a thick dough forms.
Press: Transfer the dough to the pan. Press it down firmly into an even layer using your hands or a spatula.
Melt Chocolate: Place chocolate chips and coconut oil in a microwave-safe bowl. Heat in 30-second increments, stirring until melted and smooth.
Top: Pour the chocolate over the peanut butter layer and spread evenly. Sprinkle with sea salt if desired.
Chill: Place in the freezer for 15-20 minutes until the chocolate is firm.
Slice: Finally, lift out of the pan and slice into 16 squares. Store in the fridge.
