I recently experimented with a sourdough discard breakfast recipe and fell in love. Infused with tangy unfed sourdough, rich milk, and bursts of fresh blueberries, these baked donuts deliver a delightful twist with hints of vanilla and melted butter. I invite you to relish this innovative treat, just try it.

I recently stumbled upon a twist for my favorite quick snack when I realized I could turn sourdough discard into blueberry donuts. I know it sounds kinda weird at first, but trust me it works!
I mixed 1 cup of unfed sourdough discard with 1 cup of all-purpose flour, 1/2 cup of granulated sugar, and 1/2 cup of milk to create a smooth batter. Adding 1 large egg, 2 tablespoons of melted unsalted butter, and a splash of vanilla extract gave the donuts a rich depth of flavor.
I then stirred in 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt, before gently folding in 1/2 cup of fresh blueberries. With this recipe, you can make donuts without yeast and even enjoy a creative way to use leftovers.
It’s perfect if you’re in the mood for something different and easy to whip up for breakfast or a snack.
Why I Like this Recipe
I really love this recipe cause it lets me use up my sourdough discard, which otherwise would go to waste. I also like how easy it is to make even if I’m not a master chef, the steps are simple enough that I can follow them even on busy mornings. The recipe is super forgiving and even if I mess up a little the donuts still come out light and fluffy and thats priceless. Plus, the fresh blueberries give it a pop of juiciness that turns an ordinary donut into something really special for breakfast or a snack.

FAQ
Sourdough Discard Blueberry Donuts Recipe Substitutions and Variations
- For unfed sourdough discard, you can try plain yogurt in the same amount for a similar tang.
- If you dont have all-purpose flour, whole wheat flour (equal measure) works ok but gives a nuttier flavor.
- Replace whole or 2% milk with almond milk or soy milk if you prefer a dairy-free option.
- Instead of unsalted butter, melted coconut oil or olive oil can be used, though the taste might change a bit.
- If you arent in the mood for blueberries, raspberries or blackberries can be a cool twist.
Pro Tips
1. Make sure you dont overmix the batter cause doing so can make your donuts tough; stir just until everything is combined.
2. If youre using frozen blueberries, let them thaw lightly before adding them so they dont break apart too much during baking.
3. Preheat your oven completely before you start mixing so your donuts bake evenly and come out with a nice, even color.
4. Let your donuts cool in the pan for a few minutes before moving them to a rack. This helps them set and makes them less likely to break when you take them out.
