Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.

In the bowl of a stand mixer, cream together the softened butter, coconut oil, and brown sugar until light and fluffy. Add the vanilla extract and eggs, mixing until just incorporated.

Mix in the baking soda and kosher salt. Gradually add the almond flour, 1 cup at a time, beating well after each addition. Fold in the rolled oats and chocolate chips or raisins until evenly distributed.

Form the dough into tablespoon-sized rounds and place on the lined baking sheet about 3 inches apart. Bake for 11-13 minutes, or until the edges are golden brown. Cool completely on a wire rack before serving.
