Combine room-temp eggs, honey, soft butter, and vanilla.
Mix well.
Melt coconut oil and slowly pour into batter while mixing. You want to incorporate it well, because if you don't you'll get a soggy muffin.
Combine coconut flour, salt and baking soda.
Add to batter and mix well. Give it a few minutes for the coconut flour to continue soaking in the liquid. Coconut flour absorbs a LOT of it. That's why so little is called for.
Fold in frozen berries.
Bake in 350* oven for 15-20 minutes. If you're making 12 like I did, it will take less time (18 minutes for me). If you want to go with bigger muffins, they will take longer (20+ minutes). Play it by ear. ;-)
