Last winter I took a GF baking class with my best friend, Nadia at the 577 Foundation in Perrysburg, Ohio.   The 577 Foundation offers several exceptional GF cooking classes and this baking class was over the top!  The instructor was great and the single most important tip I received was to keep on trying and testing new ideas. 

Using a blend of GF flours is key unless you find a recipe that requires very little effort by using Pamela's Baking and Pancake Mix. 

Banana Muffins with Mini Chocolate Chips
