- 1/2 teaspoon ground cinnamon (optional, but trust me, it’s a flavor boost)
- 1 large egg (binder and richness — splurge on farm-fresh if you can)
- 2 tablespoons melted unsalted butter (adds that buttery aroma and moist crumb)

Step-by-Step Instructions:
Ready to make your sourdough discard sugar donuts? Let’s roll!
- Mix the dry ingredients — In a large bowl, whisk together flour, sugar, baking powder, baking soda, salt, and cinnamon if you’re using it. This mix is your flavor base, so get it well combined.
- Blend the wet ingredients — In a separate bowl, whisk your sourdough discard with the egg and melted butter until smooth and dreamy. Don’t stress — your sourdough discard sugar donuts are about to come alive.
- Combine carefully — Pour the wet mixture into the dry ingredients. Stir until just combined. Overmixing leads to tough donuts — a few lumps are perfectly fine. Your batter should be thick, slightly sticky, but soft enough to shape.
- Heat your oil — Pour 2 inches of vegetable oil into a heavy-bottomed pot or deep fryer. Heat to 350°F (175°C). Pro tip for sourdough discard sugar donuts perfection: Use a candy or deep-fry thermometer. Temperature matters — too low and your donuts soak oil; too high and they burn.
- Shape your donuts — On a lightly floured surface, turn your dough onto the counter. Pat it into a half-inch thick slab. Use a donut cutter or two round cutters (one big, one small) to cut out rings. Don’t worry if edges aren’t perfect — rustic is the vibe here.
- Fry in batches — Drop your donuts gently into the hot oil. Cook each side for about 1-2 minutes until golden brown. In my kitchen, this sourdough discard sugar donuts adventure takes exactly 4 minutes per batch to reach golden perfection.
- Drain and sugar coat — Use a slotted spoon to transfer donuts to paper towels. While still warm, toss them in a bowl of granulated sugar for that sugary crust that crunches with every bite.
- Cool and devour — Let your sourdough discard sugar donuts cool just a bit, then grab one — or five — and enjoy. The smell alone will have everyone swooning.
Here’s where most people mess up their sourdough discard sugar donuts: oil temperature and dough consistency. Track these carefully, and you’re golden (literally). While your donuts are frying, grab your camera — they’re pure Instagram gold!

FAQs:
Q1: Can I make this sourdough discard sugar donuts spicier?
Absolutely! Swap regular sugar for a mix of cinnamon and cayenne or add chili powder to your sugar coating. It’s a bold twist that wakes up your taste buds.
Q2: What if I don’t have baking powder?
Try using more baking soda but balance with a little acid like a teaspoon of vinegar or lemon juice to keep your sourdough discard sugar donuts tender and fluffy.
Q3: Can I bake these instead of frying?
This recipe’s magic comes from frying — the sugar crust and light interior. But you can bake at 375°F for 12 minutes; just expect a different texture. For the full fried doughnuts with sourdough vibe, frying is non-negotiable.
Q4: How do I know when my sourdough discard sugar donuts are done?
Golden brown on both sides, with a pillowy softness inside. They’ll smell buttery and sweet, and should bounce back lightly when touched.
Q5: Can I freeze these homemade sugar donuts?
Yes! Freeze unfried shaped dough for a quick future batch or freeze fried sourdough discard sugar donuts wrapped tightly. Reheat in an oven to crisp them back up.
Q6: What if my dough is too sticky to shape?
Dust your hands and work surface with flour, but don’t overdo it—too much flour makes tough donuts. Also, chilling your dough 30 minutes helps.
Q7: How should I store these sourdough discard sugar donuts?
Best eaten fresh but store in an airtight container at room temp for a day or two. Avoid refrigeration as it dries them out fast.
