01 - Line an 8x4-inch loaf pan with parchment paper, ensuring the paper overhangs the sides for easy removal.
02 - Combine almond flour, coconut flour, melted coconut oil, maple syrup, and salt in a mixing bowl. Mix thoroughly until a cohesive dough forms. Press the mixture evenly into the bottom of the prepared pan, creating a compact layer. 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. This may take 2-3 minutes depending on your processor.
04 - Remove the crust from the freezer. Spread the date caramel mixture evenly over the chilled crust using a spatula, ensuring full coverage. Return the pan to the freezer for 30 minutes until the caramel layer firms up.
05 - Combine dark chocolate chips and coconut oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until completely smooth and melted. Alternatively, use a double boiler on the stovetop.
06 - Pour the melted chocolate mixture over the firm caramel layer. Spread evenly with a spatula to create a uniform top layer. Work quickly as the chocolate may begin to set upon contact with the cold caramel.
07 - Place the pan in the freezer for at least 30 minutes or until the chocolate is completely set and firm to the touch.
08 - Lift the bars out of the pan using the parchment paper overhang. Cut into 12 equal-sized bars with a sharp knife. For clean cuts, run the knife under hot water and wipe dry between slices. Store in the refrigerator for optimal texture.
