The only caveat I have is to make sure you grind the almonds really well, otherwise there's a bit of a crunch from them. I would also recommend leaving them slightly undercooked so they don't dry out. They have wonderful chocolate flavor and are easily the best brownies I've had since going gluten-free. My DH said he thought they were much better than the pre-made mixes.
