Overnight Sourdough Waffles

I may receive commission if you purchase through links in this post.

Sourdough waffles are a special breakfast any day of the week!

I make a big batch of batter and then we all sit around the table eating waffles fresh off the iron. It’s a fun way to have a communal breakfast where we all get to participate in the cooking.

These overnight sourdough waffles have a delicious buttery crisp exterior, chewy soft interior, and all the traditional sourdough flavor. They are best eaten fresh and hot right out of the waffle iron. When they cool they release steam and will get soft and chewy, losing their crisp outer layer.

Have Leftovers?

These chewy waffles even make a great portable snack that packs a lot of flavor. Use them in place of bread for sandwiches!

Reheat the waffles in the toaster to crisp them up again in no time. This trick works well with frozen waffles too!

What Makes These Sourdough Waffles So Crispy?

I bet you can guess…

Yep, extra butter! Butter is the secret to the crispiest waffles you will ever have! Try them slathered with Real Raw Cultured Butter for some extra nourishment!

Overnight Sourdough Waffles

Yield: 9 Waffles
Prep Time: 20 minutes
Cook Time: 45 minutes
Total Time: 1 hour 5 minutes

These long-fermented sourdough waffles have a delicious buttery crisp exterior and chewy traditional sourdough flavor.


  • 225 grams (1 3/4 cups) organic all-purpose flour
  • 250 grams (1 cup plus 1 tablespoon) filtered water 
  • 125 grams (1/2 cup) active sourdough starter, 100% hydration
  • 113 grams (1/2 cup) butter
  • 60 grams (1/4 cup) milk
  • 20 grams (2 tablespoons) coconut sugar
  • 2 large eggs (60 grams) 
  • 6 grams (1 teaspoon) salt


The Night Before

  1. In a big ceramic or glass bowl mix the flour, water, and starter into a sticky, thick batter. Depending on the consistency of your starter you may need to adjust the flour or water measurements. Think almost as thick as a muffin batter. Cover the bowl and let this mixture ferment overnight on your counter, or in the oven with the light on if your house is kept on the cooler side.

The Next Morning

  1. First thing in the morning check on your batter. Hopefully it will have lots of bubbles and a pleasant sour odor. If this is the case proceed with the next steps. If not, you may need some help troubleshooting your starter and I am here to help with that! Just reach out to me.
  2. Melt the butter and whisk it with the milk, sugar, eggs, and salt. I like to use a glass measuring cup for this step. Slowly incorporate the butter mixture into the fermented flour mixture. Whisk until the mixture is smooth and evenly distributed.

Just Before Cooking

  1. Plug in or heat your waffle iron. Add a careful amount of batter to the hot iron leaving room for expansion. Cook one waffle at a time until they are golden brown and puffy. Serve the waffles straight away with butter, maple syrup, and a sprinkling of fruit and nuts. Draw straws to see who gets the first one!


Pro Tip: When cooking waffles on the table use a cookie sheet turned upside down as a wide base for the waffle iron to sit on. I always have a few spill-overs and this makes it a breeze to clean up while also protecting your table from heat damage.

I will be making these soon but wondered if I do the overnight batter ferment, can I refrigerate until I'm ready to cook?

Hi Cheryl, You can absolutely refrigerate this batter! It might be advisable to let it come to room temperature and start bubbling again before you proceed with cooking.

I made these for breakfast this morning. Was a bit leery as the batter was quite tart. One they were cooked and slathered with butter and maple syrup they were most excellent. We loved how the butter in the batter led to tasty crispy edges.

I fell head over heels in love with your masa harina cornbread. I put onto 2 - 10"x14" pizza stones & cooked for 40 minutes. I used my sourdough culture (not discard) & put prepared masa harina cornbread batter in the fridge for a 3 day cold rise in a fermenting jar, wire bail & airlock. It was over-the-moon-divine results. Deelish to the MAX!!

Do you have a masa harina sourdough waffle recipe??? Thank you with warm affection, Turquoise Hooper

Hi Turquoise!

This is such a nice note! I'm so happy to hear you are loving that cornbread. You can thin the batter with milk and eggs to get to the right waffle-batter texture! I think this is such a good idea, I'm planning to make them soon, when I do I'll make sure to take notes and we can compare!

How do I convert this recipe to regular English measurements? For American use.

@Butter For All,

Thanks! Made them this morning and our family of nine all loved! I doubled it and cut the butter down to one and a half sticks and it was fine.

Hi Connie,

The cups and spoons measurements are in parentheses following the weights. I also cleaned the recipe up a little bit, so hopefully it is easier to read now.
