Editing my review to add that I made these a few times and concluded that 1/2tsp of baking powder is simply not enough to give rise to the heavy whole wheat flour. They've never risen at all. They are delicious but they didn't turn out looking anything like the picture. I did mine in 2 regular size pans and they made 12 half doughnuts, moist but dense and flat. I'm thinking they need at least 1 tsp.
They're so good! Moist, delicious, and great for a type 1 diabetic.
