Start by adding the pitted Medjool dates to a food processor and blend until smooth. Add in the almond flour and coconut oil, then pulse until the mixture turns into a dough-like texture. Press this mixture evenly into a parchment-lined baking dish. This will form the sweet, chewy base for your bars.
Mix the natural peanut butter and maple syrup in a bowl until smooth and creamy. Spread this mixture evenly over the date base using a spatula. If you love extra crunch like I do, sprinkle crushed peanuts on top before moving to the next step.
Melt the chocolate chips with coconut oil in a double boiler or microwave, stirring until smooth. Pour this glossy chocolate mixture over the peanut butter layer, spreading it evenly to coat the top. Lightly tap the baking dish on the counter to release any air bubbles.
Place the dish in the freezer for about one hour to set completely. Once firm, lift the slab out using the parchment paper and cut it into bars with a sharp knife. I found it easier to slice when slightly thawed, which gave me cleaner cuts.
