Easy Sourdough Waffles (Made With Starter Discard)

three sourdough waffle triangles on a white plate topped with berries and syrup with a gold fork beside them.

These light, crispy sourdough waffles made with sourdough starter discard are a delicious weekend breakfast or brunch that are perfect for using extra starter! (dairy-free)


  • 1 cup white whole wheat flour
  • 1 tbsp corn starch
  • 1/2 tsp baking soda
  • 1 1/2 tsp baking powder
  • 1/4 tsp salt
  • 1 tbsp butter, melted and cooled (or neutral oil for dairy-free)
  • 1 large egg
  • 1 tsp vanilla extract
  • 3/4 cup sourdough starter discard
  • 1 - 1 1/2 cups club soda (or milk of choice)
  • Optional: 1 tbsp brown sugar and/or 1 tbsp ground flaxseed


  1. In a large bowl, mix together dry ingredients (flour, cornstarch, baking soda, baking powder and salt).
  2. Whisk the melted and cooled butter, egg, vanilla and starter. Add to the dry ingredients, along with the soda. Add more soda as needed to reach a thinner consistency if your starter is thicker/lower hydration.
  3. Spray or brush a hot waffle iron with oil. Pour batter into waffle iron and cook according to the instructions.
  4. Serve waffles with maple syrup, butter, whipped cream, or berries.


  • Your starter discard does not need to be active or recently fed for this recipe.
  • Tapioca or arrowroot starch may be used in place of cornstarch.
  • If you don't have club soda (or seltzer water), you can substitute the milk or your choice, though they won't be quite as fluffy and airy.
  • If you like sweeter waffles, add 1 tbsp brown sugar with the dry ingredients.
  • I like to add ground flaxseed to my waffles for a little nutrition boost. You can add 1-2 tbsp in with the dry ingredients.
  • You can add mix-ins to the batter at the end, like chocolate chips or blueberries!
  • To freeze waffles, let them cool completely, then layer between sheets of parchment or wax paper. Place in a freezer bag or other airtight container and freeze. When you're ready to reheat them, pop the in the toaster or in a 400°F oven for a few minutes.
