These easy Sourdough Discard Waffles are fluffy inside and perfectly crisp on the outside. And they use a whole cup of sourdough discard! Make them right now or stash the batter in the refrigerator overnight to make them fresh tomorrow morning. If your starter is well-established, you will actually get some fermentation during that overnight rest too!

Is there anything better or more nostalgic than waffles on the weekend? Just seeing that old waffle maker pulled from its cabinet floods me with not only memories of my own childhood, but also memories of making waffles for my kids when they were little. I've been reliving those old memories by making these waffles for my toddler lately and it has been so sweet! We also love to make my Overnight Sourdough Pancakes, which this recipe is based on, but these waffles have been an extra special treat lately.

Step-by-Step Instructions
Here are the easy instructions for these sourdough discard waffles. I give long-fermenting instructions below this section as well as in the recipe card.

Mix dry ingredients in a mixing bowl.

Add wet ingredients.

Mix until combined.

Pour batter onto preheated waffle iron. Mine takes about ¾ cup.

Cook until golden brown according to your waffle maker's instructions.
Overnight Long-Fermentation Option
If you have a well-established starter and you want to long ferment this batter, once you mix the waffle batter you can leave it at room temperature for up to 2 hours before placing in the refrigerator for up to 24 hours before cooking. Make sure it is covered well so it does not dry out.
If your starter is less than two weeks old, you can still use the refrigerated overnight option but you won't get much, if any, fermentation.

Sourdough Discard Waffles Recipe
These easy Sourdough Discard Waffles are fluffy inside and perfectly crisp on the outside. Make them right now or stash the batter in the refrigerator overnight to make them fresh tomorrow morning. If your starter is well-established, you will actually get some fermentation during that overnight rest too!
- Total Time: 30 minutes
- Yield: 4-6 servings
Ingredients
1 ½ cups or 210 grams all purpose flour
1 teaspoon baking powder
½ teaspoon baking soda
½ teaspoon kosher salt
1 cup or 280 grams sourdough starter, unfed or active, stirred down well before measuring
1 cup or 249 grams buttermilk or milk
2 tablespoons honey or sweetener of choice
¼ cup or 56.5 grams melted butter or other oil/fat
1 egg
1 teaspoon vanilla extract
Instructions
- Combine flour, baking powder, baking soda, and salt in a mixing bowl. Whisk to combine.
- Add remaining ingredients to the flour mixture and whisk again to combine. You will have a slightly thick but still pourable batter. If it seems too thick add a splash more of milk to thin.
- Cook in preheated, greased waffle iron until golden according to manufacturer's instructions. Mine takes about ¾ cup of batter but this will vary depending on your model.
- Serve warm with butter, syrup, or your favorite waffle toppings.
Notes
- If you have a well-established starter and you want to long ferment these Sourdough Discard Waffles, once you mix the waffle batter you can leave it at room temperature for up to 2 hours before placing in the refrigerator for up to 24 hours before cooking. Make sure it is covered well so it does not dry out.
- To reheat, place in toaster on the lightest setting until warm and slightly crisped.
- If you want to add chocolate chips, blueberries, or other add-ins I suggest adding a cup to a cup and a half to the batter just before cooking.
