Sourdough Discard Pancakes Recipe
Fluffy sourdough discard pancakes made with unfed starter: 15 minutes of hands-on time, no rising needed, and they keep overnight.

This sourdough discard pancakes recipe is the highest-reward bake in the sourdough kitchen: 150 g of unfed starter you'd otherwise toss turns into thick, fluffy, tangy pancakes in 25 minutes flat. No yeast, no feedings, no waiting — and no active starter needed.
Why this recipe works
The chemistry is beautifully simple. Sourdough discard is rich in lactic and acetic acid, and baking soda is alkaline — when the two meet, they produce carbon dioxide bubbles exactly the way buttermilk does in a classic pancake. That reaction replaces any need for baking powder or yeast, and it's why these pancakes rise on the griddle, not in a bowl.
Two details separate these from a flat, rubbery batch: the batter rests for 10 minutes after mixing, and it's handled gently. Both are non-negotiable if you want the light texture in the photos.
Notes on the discard
Any discard works — young, old, refrigerated for two weeks, hooch included (stir it in). What matters is consistency, not activity. A thick, stiff discard gives a slightly thicker pancake; a watery one produces a thinner batter that spreads on the griddle. If your discard is very wet, cut the milk back by 20–30 g and judge by eye: the batter should pour slowly off a spoon, not flow like cream.
Doubling and swapping
This recipe scales cleanly for a crowd — just keep the 1:1:1.7 discard-to-flour-to-liquid ratio. For extra tang, replace half the milk with buttermilk. For a whole-grain version, swap half the all-purpose flour for whole wheat and add 30 g more milk. And the classic upgrade: a handful of fresh blueberries folded in right before cooking, so they don't bleed and turn the batter grey.
Storage
Pancakes keep for 3 days in the fridge in a sealed container, and they freeze flat for up to 2 months — reheat straight from frozen in a toaster. Reheat slowly; a hot toaster on a frozen pancake leaves a cold middle.
Ingredients
Weights in grams are the source of truth; cup measures are approximate.
- 150 g sourdough discard (unfed, straight from the fridge)
- 150 g all-purpose flour
- 25 g sugar
- 1 tsp (5 g) baking soda
- 1/2 tsp (3 g) fine salt
- 2 large eggs (about 100 g)
- 30 g unsalted butter, melted, plus more for the pan
- 250 g whole milk (or buttermilk for extra tang)
- 1 tsp vanilla extract (optional)
Method
In a large bowl, whisk the eggs, milk, melted butter, and vanilla together until combined.
Whisk in the sourdough discard — lumps are fine; don't overmix or the pancakes go tough.
In a separate bowl, whisk the flour, sugar, salt, and baking soda. Add to the wet mixture and fold with a spatula just until no dry flour remains. A few small lumps are exactly right.
Rest the batter for 10 minutes. This lets the flour hydrate and the baking soda begin reacting with the acid in the discard — it's what makes the pancakes light.
Heat a griddle or heavy skillet over medium heat and melt a small knob of butter across the surface.
Pour 1/4-cup (60 ml) scoops of batter. Cook until bubbles form and pop on the surface and the edges look set, about 2-3 minutes.
Flip and cook 1-2 minutes more, until golden brown and cooked through. Keep warm in a 200°F oven while you finish the batch.
Serve with butter and maple syrup. Leftover pancakes keep for 3 days in the fridge and freeze beautifully.
Frequently asked questions
Do I need an active starter for sourdough discard pancakes?
No — that's the whole point. Unfed discard straight from the fridge works perfectly. The baking soda reacts with the starter's lactic acid for lift, so the starter doesn't need to be bubbly.
Can sourdough discard pancakes be made gluten-free?
Swap the all-purpose flour for a 1:1 gluten-free flour blend. Add 1/4 cup more milk if the batter seems thick, and expect a slightly more delicate pancake. Baking soda lift still works the same way.
Why are my sourdough discard pancakes gummy or dense?
Usually one of three things: overmixed batter, a cold pan, or too little baking soda. Mix just until combined, let the pan come fully to medium heat, and use a fresh jar of baking soda — old baking soda is the quiet killer of fluffy pancakes.
Can I make the batter the night before?
Yes, but wait to add the baking soda until the morning. Mix everything except the baking soda, cover, and refrigerate; then fold in the baking soda right before cooking. Overnight also deepens the sour flavor.
How much sourdough discard does this recipe use?
150 g — the perfect amount for a 300 g weekly feeding cycle. If you have more discard, this recipe scales linearly: keep the ratio of discard to flour to liquid at roughly 1:1:1.7.
