This does look really good. And it is gluten-free to!
We do a lot of different things made with almond meal. Low-carb and gluten-free baked goods are usually very crumbly. We have found that, pretty consistently, these items work best after they are refrigerated overnight. I know, it takes way that fresh-baked brownie. But in many cases it actually improves both flavor and mouth feel. Most of the time we also add in some cream cheese. This makes a big difference in how things bind together as well.
