Except it isn't! What you see up there are in fact sugar donut muffins. This was the first recipe I thought of the moment I had a successful batch of caramel sauce.
When Valerie filled her muffin tins with batter and added a drizzle of caramel on top, she fully intended the caramel to sink in the middle and become a filling for a muffin.
My caramel sauce must be heavier for it sort of sunk and then created donut holes. Which is fab because I seem to have accidentally discovered a dessert that looks like part muffin, part donut. And once brushed with butter and dipped in sugar, tastes better than either!
