Preheat oven to 425 F.Mix dry ingredients together and set aside.Mix wet ingredients in a separate bowl.Add wets to dries and then add nuts if using.Put into greased muffin tins (mini or regular size) or for a simpler option (my favorite....cleaning muffin tins is one of my least favorite jobs in the kitchen :-)) simply place on a prepared cookie sheet or baking stone.Bake for 10-20 minutes until the middles are pretty well set.
