I LOVE this question. If you don't have a donut pan you can use a muffin pan and aluminum foil. Grease the muffin pan then take a piece of aluminum foil, wrap it around your finger to form a cylinder shape, then press into the center of a muffin tin cavity so it's standing up straight, and pour the batter in. The aluminum foil should stick because you greased it but you could press it down a little bit so it has a flat bottom.
