01 - Line an 8x4-inch loaf pan with parchment paper, ensuring overhang on all sides for easy removal.
02 - Combine almond flour, coconut flour, melted coconut oil, maple syrup, and salt in a mixing bowl. Mix until a cohesive dough forms. Press the mixture firmly and evenly into the bottom of the prepared pan. Freeze for 15 minutes until set.
03 - Place pitted Medjool dates, almond butter, coconut milk, vanilla extract, and salt in a food processor. Blend until completely smooth and creamy, scraping down the sides as needed. Spread the caramel mixture evenly over the chilled crust. Return to the freezer for 30 minutes until firm.
04 - 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, melt using a double boiler over gentle heat.
05 - Pour the melted chocolate over the firm caramel layer, spreading evenly with a spatula to cover completely. Freeze for at least 30 minutes or until the chocolate is completely set.
06 - Lift the bars from the pan using the parchment paper overhang. Cut into 12 equal bars. For best texture and flavor, store in the refrigerator.
