I was in a baking mood, so I tried this recipe from a Specific Carbohydrate Diet site:
CASHEW BUTTER MUFFINS
1 cup cashew butter
2 small bananas
1/2 tsp baking soda
1 tsp apple cider vinegar
Blend cashew butter and banana in food processor until completely blended.
Add eggs and blend again.
Add 1/2 tsp baking soda, blend again.
Add 1 tsp vinegar, blend again.
Divide batter into 12 cupcake paper lined muffin tins.
Bake at 400 for 10 minutes.
These muffins even had little air pockets in them like regular ones.
Light and fluffy, not at all heavy.
They came out very well! I folded in some organic, fresh blueberries for half the batter, and those were especially good. I think I would add some spices next time (cinnamon? cardamom? nutmeg?). BTW, I don't have a food processor, so I just mixed it all by hand--Grok on!
Some of the other recipes look pretty good--those folks are definitely into grain-free, but they do go for some cheese/yogurt and they're very big on honey.
