This recipe is a classic recipe for gluten-free brownies. Do not look for anything in it. It's just good to have a crunchy, at the same time sticky, bitterly sweet chocolate delicacy. Essential is the dough structure and especially baking. You have to capture the right moment to keep the dough structure still sticky inside, but a crisp, crisp layer has formed on the surface. The resulting flavor, of course, fundamentally affects the chocolate of choice, so choose a quality and one that tastes good for you. Brownies are great as they are, but if you like walnuts, pecans or hazelnuts, they will only add value. I personally love walnuts combined with chocolate! Cut nuts on the pan before they get a much more delicate and distinctive pure nut flavor.
