Preheat oven to 350F.
Sift all dry ingredients together for base batter (flours, protein, baking powder, salt) and set aside.
Beat all wet ingredients for base better together until smooth (egg, maple syrup, applesauce, yogurt).
Add dry ingredients to wet and stir to combine (or mix on low with paddle attachment until combined).
Separate half the batter into another bowl and mix in the brownie layer ingredients except for the chocolate chips.
Divide the chocolate chips between the two bowls and fold into each layer.
Line a loaf pan with parchment paper and spread the brownie layer on the bottom. Then spread the cookie dough layer on top.
Bake for 35-40 min until a toothpick comes out clean.
Cool for 10 min in the loaf pan then remove to finish cooling on a wire rack.
Try not to eat it all in one night!
