Yes, you can use a silicone donut pan with this recipe. Silicone pans don't need to be sprayed with oil or greased before baking. Once baked the donuts will pop easily out of a silicone pan. I recommend placing the silicone pan on a metal baking sheet before placing in the oven. This will help the silicone pan be sturdier as you pull it in and out of the oven and can keep you from accidentally spilling hot batter in the oven or on yourself. Baked treats cooked in silicone tend not to brown as well, but as these donuts are chocolate and are frosted you won't see that in the finished donut.
