Preheat oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper

In a bowl, mix almond flour, sweetener, baking soda, and salt for the cookie layer

Add butter, egg, and vanilla, then mix until a soft dough forms

Fold in chocolate chips and press about two-thirds of the dough into the pan

In another bowl, combine almond flour, cocoa powder, sweetener, baking powder, and salt for the brownie layer

Add butter and egg, mixing until smooth and thick

Spread brownie batter evenly over the cookie layer

Drop small portions of remaining cookie dough on top

Bake for 25–30 minutes until edges are set but center remains soft

Allow to cool before slicing into squares for best texture
