Not Moco but in upper NW we really like the one at Bread Furst (Connecticut and Albemarle).

Sorry - the above was the incorrect link

Cooper's Hawk in Rockville has a flourless chocolate torte - and if its anywhere near as good as their other menu items, you'll be set.

I think Wegman’s has a good one.

I didn’t feel like baking. Found a little yummy Oreo cookie so sized one at Whole Foods for $2. Just needed a taste. Will check out the cafe listed sometime soon.

Just bake one, so easy

I don’t know about flourless but cafe Lilit on old Georgetown has a lot of gluten free sweets.

Greetings! I’ve been without processed foods, processed sugar and desert like foods since Jan 9. I am not ready to return to flour/gluten. Do you know where I can find flourless chocolate cake or brownie. Would prefer not to buy a whole cake! I might eat it. TIA
