In a large bowl, add 1/2 cup melted coconut oil or butter, 2/3 cup cashew butter, and 1 cup coconut sugar. Use an electric hand mixer to combine everything together.
Now add 1 egg, 1 egg yolk, and 1 teaspoon vanilla extract. Mix again.
Then mix in 1 cup coconut flour, 1 teaspoon baking soda, and 1 teaspoon salt.
Once the cookie dough begins to take shape, mix in 1 cup dark chocolate chunks or chips.
Line a baking sheet with parchment paper and place scoops of the coconut flour cookies on top. I used a medium sized cookie scoop and got 28 cookies out of this recipe.
Now flatten the cookies slightly before baking and add additional chocolate chunks on top. Bake at 350 degrees Fahrenheit for about 8 minutes.
