My Personal Experience

• Effortless discard transformation – Turning what was once kitchen waste into these fluffy donuts feels incredibly rewarding. The sourdough discard adds a subtle tang that elevates the flavor profile beyond standard donuts.

• Perfect texture achievement – After several attempts, I found that chilling the dough makes handling effortless. The result is consistently light, airy donuts with a beautiful golden crust.

Why You’ll Love This Recipe

• Uses up sourdough discard – Reduces kitchen waste while creating something delicious. This recipe gives purpose to the discard you’d otherwise throw away.

• High protein content – Each serving delivers quality protein to support muscle health. The combination of eggs, almond flour, and optional protein powder provides substantial nutritional value.

• Low-carb friendly – Almond flour keeps net carbs minimal compared to traditional wheat flour. Perfect for those monitoring carbohydrate intake or following keto lifestyles.

• Incredibly versatile – Customize with different glazes, spices, or toppings. Make it chocolate, cinnamon sugar, or berry glazed based on your cravings.

• Better than store-bought – Fresh, homemade donuts without preservatives or artificial ingredients. You control exactly what goes into your treat.

Common Mistakes to Avoid

• Overmixing the batter – Develops too much gluten, resulting in tough, dense donuts. Mix until just combined for the best texture .

• Incorrect oil temperature for frying – Oil that’s too hot burns the outside before cooking the inside; too cool makes greasy donuts. Maintain 350-375°F for perfect golden results .

• Skipping the chilling step – Unchilled dough is too sticky to handle and shape properly. Refrigerate for at least one hour to make cutting and shaping effortless .

• Overbaking in the oven – Results in dry, crumbly donuts instead of soft, tender ones. Remove as soon as a toothpick comes out clean .

Required Equipment

• Stand mixer with dough hook – Makes kneading effortless and ensures proper gluten development. Works the dough consistently without overmixing .

• Donut cutter or two round cutters – Creates perfectly shaped donuts with classic form. Large cutter for the outside, small for the hole.

• Deep-frying thermometer – Crucial for maintaining correct oil temperature. Prevents soggy or burnt donuts .

• Donut baking pan – Essential for baked versions, holds the batter securely. Creates uniform donuts that bake evenly.

• Parchment paper – Prevents sticking and makes easy cleanup. Line baking sheets for proofing and cooling.

Storage Instructions

Store leftovers in an airtight container at room temperature for 1-2 days . For longer storage, freeze unglazed donuts in a single layer in a freezer-safe container for up to 2 months . Thaw at room temperature and reheat in a microwave for 10-12 seconds before adding glaze . Place parchment paper between layers to prevent sticking .

Light, fluffy sourdough discard donuts made healthier with high-protein ingredients. Perfect for reducing kitchen waste while enjoying a satisfying, macro-friendly treat that doesn’t compromise on taste.

📝 Ingredients

Dry Ingredients

• 1 ⅛ cups (126g) almond flour

• ½ cup (40g) unflavored pea or whey protein powder

• ½ teaspoon baking powder

• ½ cup granulated erythritol or monk fruit sweetener

• ½ teaspoon xanthan gum (improves texture and structure) 

• ¼ teaspoon salt

Wet Ingredients

• 2 large eggs, room temperature

• ⅔ cup (151g) butter, melted and cooled

• 1 teaspoon vanilla extract

• ½ cup sourdough discard (room temperature) 

Optional Glaze

• 1 cup fresh or frozen berries

• 3 tablespoons protein powder

• ¼ cup powdered erythritol

• 2-3 tablespoons almond milk 

Directions

1. Preheat oven to 350°F (175°C) and grease a donut pan thoroughly with butter or cooking spray .

2. Mix dry ingredients – In a medium bowl, whisk together almond flour, protein powder, baking powder, sweetener, xanthan gum, and salt until well combined .

3. Combine wet ingredients – In a separate large bowl, whisk eggs with melted butter, adding them one at a time and whisking vigorously after each addition. Stir in vanilla extract and sourdough discard .

4. Combine batter – Fold wet ingredients into dry mixture until just combined. Be careful not to overmix, as this can make donuts dense and tough .

5. Fill pan – Transfer batter to a piping bag or zip-top bag with a corner snipped. Pipe evenly into the donut cavities, filling each about ¾ full. Smooth tops with a damp finger if needed .

6. Bake – Place in preheated oven and bake for 10-12 minutes, or until tops spring back lightly and a toothpick inserted comes out mostly clean with a few moist crumbs. Watch closely to avoid overbaking, which creates dry donuts .

7. Cool – Allow donuts to cool in the pan for 5 minutes, then carefully transfer to a wire rack to cool completely before glazing .

8. Make glaze (optional) – While donuts cool, puree berries in a food processor. Add protein powder, powdered erythritol, almond milk, and vanilla, processing until smooth. Adjust consistency with more almond milk if needed .

9. Glaze and serve – Dip cooled donut tops into the glaze, allowing excess to drip off. Place back on the wire rack and let glaze set for 10-15 minutes before serving .
