To prepare the Oat Base, add the oats, nuts, and pitted dates into a blender until fully combined and no chunks remain. Add 2 tablespoons of water and blend until combined. You may need to add an additional 1-2 tablespoons to get a sticky texture.

Pour the oat mixture into a parchment lined 9x9 baking dish. Pat down firmly with your hands or the back of a spoon. The mixture should be slightly sticky and should be patted down to form an even layer. Set aside.

In a separate bowl or large measuring cup, add the cocoa powder and maple syrup to the melted coconut oil. Stir to combine. Pour the chocolate coating over the oat base to form an even layer.

Place the oat bars in the fridge to set for at least 30 minutes.

Remove the oat bars from the fridge once set, and slice into 16 bars.

Store the bars in the fridge for up to a week, or in the freezer for up to a few months.
