Can I bake these maple-glazed donuts instead of frying them, and if so, how should I adjust the recipe?
Yes—you can bake the dough in a well-greased or non-stick donut pan at 375 °F (190 °C) until the rings are lightly golden, 10–12 minutes, then immediately brush the hot donuts with melted butter to mimic the richness lost from frying. Because the batter won’t be submerged in oil, keep it slightly looser by adding 1–2 tablespoons extra milk, and expect a lighter, cake-style crumb; proceed with the maple glaze and brown-butter icing as written once the donuts cool just enough to handle.
Can I prepare the dough in advance and refrigerate or freeze it for later frying, and what adjustments are needed?
Yes—after the first rise, cut the rings, lay them on parchment, cover, and refrigerate for up to 24 hours; when ready to fry, let them stand 20–30 minutes at room temperature so the yeast reactivates and the centers stay light. For longer storage, freeze the shaped, unproofed donuts on a tray until solid, transfer to an airtight bag for up to a month, then thaw overnight in the fridge and proof 45–60 minutes at warm room temp before frying, adding an extra ⅛–¼ tsp yeast to the dough if you know in advance they’ll be frozen.
How should I store and reheat leftover maple-glazed donuts to keep them fresh?
Let the glazed and iced donuts cool completely, then place them in a single layer (or separated by parchment) in an airtight container for up to 24 hours at room temperature; for longer keeping, freeze them on a sheet pan until solid, transfer to a zip-top bag, and hold up to one month. To refresh, thaw any frozen donuts at room temperature, then warm in a 300 °F (150 °C) oven for 4–5 minutes—or microwave unwrapped for 10–12 seconds—just until the crumb is soft and the glaze looks glossy again, taking care not to overheat or the icing will melt.
