    1. I’m not sure, mine were firm! Maybe bake longer? Or did you use anything different than what I used?

  1. These Egg Fast Donuts are my new favorite! Quick to make, delicious to eat! I have made them 3 times in the last 10 days. The first time with butter, the next time with mayo, baked at 350* because I had other stuff in the oven. Today, with mayo and at 325*. I never sprinkle them with extra cinnamon and sweetener, just eat them cold out of the frig. Perfect finger food! Mine seem to deflate a lot while they are cooling but it doesn’t affect my enjoyment of them! Thank you!
