Sourdough Apple Muffins

These sourdough apple muffins were requested by a reader who asked for an apple muffin recipe packed with apples. Because fruit is an afterthought in too many recipes.

Not true for these sourdough discard apple muffins, with over one cup of apple in eight muffins. And, as a bonus, they are quick and easy, coming together in under 30 minutes if you are without distractions.

Baking ratios

This sourdough apple muffin recipe is based on Michael Ruhlman’s ratios. According to Ruhlman, the standard formula for muffins and quick breads should be 2 parts flour: 2 parts liquid: 1 part egg: 1 part butter (by weight). The only trick in this recipe is to account for the flour and liquid in your sourdough discard.

Tips and tricks for these apple muffins

  • Sourdough discard can be used in any recipe that uses flour and water or other liquid like milk or buttermilk. The discard will just give it a slightly more sour or tangy taste, which is particularly great in any recipe where you’d use buttermilk. You just need to calculate the amount of flour and water in your starter and reduce the amount of flour and liquid in your recipe by that amount.
  • Brown butter adds a deeper, caramel and nutty flavor to your baking. If you prefer, you can just melt the butter and stop before the browning stage.
  • Disclosure: I was recently given two boxes of HunnyZ apples by the folks at Gee Whiz after I wrote a post about late season apples and discovered how much I loved this new apple, which is a cross between a Honeycrisp and Crimson Crisp apple.

FAQs about this sourdough apple muffin recipe

Do I really have to weigh my ingredients?

No, you don’t have to do anything, but you will get more consistent results if you weigh your ingredients, especially for baking. Plus you dirty fewer measuring cups!

What apple should I use in these muffins?

I used a HunnyZ apple because it remains firm when cooked and has a strong apple flavor. You could use a tart apple (e.g. Granny Smith, Pink Lady) to increase the tang in these sourdough discard muffins, or any sweet, crisp apple.

What can I substitute for buttermilk in these sourdough discard apple muffins?

I would reach first for yogurt, but you could also use milk or an unsweetened non-dairy milk.

I don’t have a sourdough starter. Is there something else I can use?

A 100% hydration starter is equal amounts of water and flour. If you don’t have a starter, just add an additional 2 ounces (57 grams or one-third cup) of flour to the dry ingredients and an additional 2 ounces (one quarter cup) of buttermilk or other liquid.

My sourdough starter has a different hydration level, can I still use it?

Yes, you’ll just need to calculate the amount of water and flour in your starter. And add flour and liquid to get to 4 ounces of each.

Can I prepare the sourdough discard muffin batter ahead of time?

Muffins, pancakes, and waffles should be made soon after the batter is put together. It’s always better to bake muffins and then freeze them if you want to make them in advance.

Can I freeze these sourdough discard muffins?

Yes! Muffins freeze very well. After they have cooled, place them in a freezer bag and remove all of the air. You can let them warm at room temperature, or pop them in a warm oven to defrost.

Can I decorate these apple muffins?

If you want to add a bit of decoration, I would add just a simple layer of coarse decorating sugar on top about 10 minutes into baking.

    Just made these muffins – they came out scrumptious! I used yogurt instead of buttermilk (it’s what I had on hand) and added 1/8 tsp allspice, just to warm things up a bit. So yummy! Thanks for the great recipe!
