Place the macadamia nuts into a blender or food processor and pulse until they reach a coarse, crumbly consistency.
In a medium mixing bowl, combine the softened coconut oil and the shredded coconut.
Mix until well combined.
Add the crushed macadamia nuts and the liquid stevia to the bowl.
Stir the mixture thoroughly to ensure the sweetener and nuts are evenly distributed throughout the batter.
Line a 9x9 inch baking dish with parchment paper.
Pour the batter into the dish and use a spatula to press it down into a firm, even layer.
Refrigerate for at least 4 hours, or overnight, to allow the bars to set completely.
Once firm, lift the parchment paper out of the dish.
Cut the block into 9 equal bars and serve immediately.
Freezer is Your Friend: For a firmer, crunchier texture, store these bars in an airtight container in the freezer instead of the fridge. They hold their shape better and won't soften as quickly at room temperature.
