How to Make Sourdough Discard Donuts
Phase 1 – Prep
STEP 1. Mix Milk and Sugar. In the bowl of a standing mixer fitted with the dough hook attachment, mix together warmed milk and granulated sugar.
STEP 2. Activate Yeast. Sprinkle the yeast over the top of the milk mixture and let it sit for 5-10 minutes until foamy.
STEP 3. Add Ingredients. Beat the sourdough discard, softened butter, 2 eggs, and nutmeg until mixed.
STEP 4. Incorporate Flour. Gradually add flour, one cup at a time, then continue mixing on medium speed for 4-5 minutes or until the dough forms a loose ball.
STEP 5. Refrigerate Dough. Place dough in a greased bowl, cover with plastic wrap, and refrigerate for at least 1 hour or overnight.
Phase 2 – Cook
STEP 6. Divide Dough. Once doubled in size, divide the dough and roll to 1/2-inch thick.
STEP 7. Cut Out Donuts. Cut out donuts and place on a parchment-lined baking sheet.
STEP 8. Let Rise. Cover and let rise for about 1 hour.
STEP 9. Heat Oil. Heat oil to 375 F.
STEP 10. Fry Donuts. Fry donuts on each side for 1-2 minutes until golden brown.

Why This Recipe Works
The balance of textures in these donuts is superb. The outer crust, achieved through frying, provides satisfying crunch while the inner donut remains pillowy soft. Flavor layering enhances the experience as the sweet glaze interacts with the slight tang of sourdough, creating an indulgent yet comforting bite. Ingredients interact harmoniously: the yeast makes the dough rise beautifully, while butter and eggs contribute richness and moisture. The frying method creates a more decadent treat than baking, giving a unique depth that sets this recipe apart.
