I love baking. Since two of us have had to eliminate all gluten, I tend to bake less, use the dehydrator more, and would generally just prefer to eat other foods rather than "substitute" foods. But my two that are fine with gluten and also love baked goods are so very happy when I bake. My husband also loves to have something for his kaffeeklatsch (he works from home most days). He tends to work non-stop most of the day and leaves half of his lunch untouched on his plate up in his office. He is usually starving by mid afternoon and this helps him get along. Any gluten free goodies that I bake have to be approved and dearly loved by those that COULD eat gluten if it wasn't for us (ahem), as well as by my allergy boy. By having a few base recipes that I can adapt to whatever fruit is seasonal in the garden means that I have something I KNOW everyone likes and that I can make easily with whatever is ready NOW. This cake is a great base. And with strawberries and rhubarb? Over the top.
As I said, the main recipe is a great base. If you don't want to make it using strawberry/rhubarb, make everything as a stand alone cake (skip the rhubarb/strawberry steps, leave out the cinnamon, and no need to invert). My boys love it as a pound cake with a lemon glaze over the top (see above).
Now, for the GF flour mix. I really like theratio guide over at Gluten Free Girl and the Chef. It is clear and easy to remember and no matter how I mix it, it is a solid ratio and things come out great. I have used this cake recipe with several different blends of my own making as well as a few different store bought GF all purpose blends. Always good. This rich dark amazingly delicious rhubarb upside down cake was made using a blend I made that has several different GF whole grain flours including buckwheat, which is what adds to the lovely color (in addition to coconut palm sugar). So good and moist.
