Preheat your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, leaving an overhang on the sides to easily lift the bars out later.
In a large mixing bowl, combine the melted coconut oil, maple syrup, egg, and vanilla extract. Whisk them together until the mixture is smooth and well-combined.
Add the cassava flour, baking soda, and sea salt directly into the wet mixture in the same bowl. Stir with a spatula until just combined. Be careful not to overmix the dough. It will be thick.
Gently fold in the paleo chocolate chips until they are evenly distributed throughout the dough.
Transfer the dough to the prepared baking pan. Use your spatula or damp hands to press the dough evenly into the pan, ensuring it reaches all corners.
Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out mostly clean (a few moist crumbs are okay).
Remove the pan from the oven and let the bars cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang. This is crucial for them to set properly and not crumble.
Once cooled, cut the cookie bars into 9-12 squares. Serve and enjoy your healthy, gluten-free treat!
Notes
For best results, ensure the bars are completely cool before cutting; this allows them to firm up and prevents crumbling. Store leftover bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. You can also freeze them for longer storage.
