Thanks for the info. The original recipe I saw called for using a box cake mix, but I found a similar recipe online that is more of a scratch recipe and the ingredients appear to be what would be in the cake mix. I will post the recipe on the recipe thread. I have been dragging my feet making this because it's been so hot to turn on the oven, but I have to get to it soon! DH likes blueberries and loves cake! As a diabetic, I can eat the blueberries but not the cake.
