Our local grocery store has recently begun carrying Betty Crocker Gluten-Free products. Having tried many, many, many gluten-free mixes over the past eight years and been very, very, very disappointed, I didn’t have very high hopes for this cake.
But Betty proved me wrong. This was a great cake, with just a handful of ingredients: rice flour, sugar, potato starch, leavening (baking soda, sodium acid pyrophospate, monocalcium phospate), xantham gum and salt. You add eggs, water and butter (we used our old friend, Earth Balance margarine).
We made the icing with Earth Balance, cocoa, icing sugar and rice milk.
Mmmm, leftovers!
Three Boring Sisters 
Yum. That looks like a great dessert to serve to guests. Like say, to a sister and her family??? Hint!
