01 - Line an 8x4-inch loaf pan with parchment paper, ensuring paper overhangs on all sides for easy removal.
02 - Combine almond flour, coconut flour, melted coconut oil, maple syrup, and salt in a mixing bowl. Stir until a cohesive dough forms. Press the mixture firmly and evenly into the bottom of the prepared pan. Freeze for 15 minutes to set.
03 - Place pitted Medjool dates, almond butter, coconut milk, vanilla extract, and salt in a food processor. Blend on high speed until completely smooth and creamy, scraping down the sides as needed. The mixture should be thick but spreadable.
04 - Remove the crust from the freezer. Spread the date caramel mixture evenly over the chilled crust, using a spatula to create a smooth layer. Return the pan to the freezer for 30 minutes until firm.
05 - Combine dark chocolate chips and coconut oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until completely melted and smooth. Alternatively, use a double boiler on the stovetop.
06 - Pour the melted chocolate over the firm caramel layer. Quickly spread evenly with a spatula to cover the entire surface. Place in the freezer for at least 30 minutes or until the chocolate is completely set.
07 - Lift the bars out of the pan using the parchment paper overhang. Place on a cutting board and cut into 12 even bars. Store in an airtight container in the refrigerator for optimal texture and freshness.
