Sunshine Muffins or Cupcakes - My version of a popular recipe with GF option

Okay, so I haven't had any trouble with substitutions and alternative flours for my gluten-free friends, so I will often post the alternatives, or if I forget, haggle me.
These muffins, could also be cupcakes. I heard it once said that muffins were "mini cake wads" and I translated that to cupcakes. It's really the same ingredients except muffins usually have chunky bits. So that is what separates this recipe out: add chunky bits and it's muffins, add icing, and it's cupcakes.
Either way, they are stupid easy because you can do them in a blender or food processor and just pour.
