Sourdough Discard Apple Muffins

These sourdough apple muffins were requested by a reader who asked for an apple muffin recipe packed with apples. They are quick and easy, coming together in under 30 minutes.

The fruit seems to be an afterthought in too many apple muffin recipes. That’s not true for these sourdough discard muffins with over one cup of apple in eight muffins.

Key technique: baking ratios

The base of this sourdough discard muffin recipe is from Michael Ruhlman’s Ratio. According to Ruhlman, the standard formula for muffins and quick breads is 2 parts flour: 2 parts liquid: 1 part egg: 1 part butter by weight.

Key ingredient: sourdough discard

Sourdough discard is what you are left with after you feed a sourdough starter. Instead of throwing it away, you can use sourdough discard in any recipe with flour and liquid. The discard will give it a slightly sour or tangy taste, which is particularly great in recipes with buttermilk.

Calculate the amount of flour and water in your starter and reduce the amount of flour and liquid in your recipe by that weight. It’s easy if you have a 100% starter that’s equal amounts of flour and water.

You can obviously use your sourdough discard to add flavor to yeast breads like this sourdough discard bread. But you can use sourdough discard in pancakes, waffles, and cakes like this sourdough apple cake.

Tips and tricks

Tip from the wise quacker: If you don’t have sourdough starter, you can still make this recipe. Use an additional 2 ounces (57 grams or one-third cup) of flour and an additional 2 ounces (one quarter cup) of buttermilk or other liquid.

Baking with apples

The best apple for these sourdough muffins is one that remains firm when cooked and has a strong apple flavor. Using a tart apple like a Granny Smith or Pink Lady will increase the tang even more.

Step by step

Brown butter adds a deeper, caramel and nutty flavor to your baking. If you prefer, you can melt the butter and stop before the browning stage.

Muffins are typically made using the “muffin method.” Using this method, you first whisk the dry ingredients in a large bowl. Then combine the buttermilk, brown butter, egg, and vanilla in a large measuring cup and add them to the dry ingredients.

Like with other muffins, waffles, and pancakes, mix only until the dry ingredients are completely moistened. Then add the chopped apples and scoop into your prepared muffin tin.

Variations and substitutions

  • Substitute yogurt, milk, or an unsweetened non-dairy milk for the buttermilk.
  • Decorate your muffins by adding coarse decorating sugar to the top about 10 minutes into baking. Or make a glaze with a cup of confectioners’ sugar, teaspoon of cinnamon, and a tablespoon or two of buttermilk, cream, or milk.

FAQs

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!

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

Yes, you’ll 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?

You should always make muffins, pancakes, and waffles soon after you make the batter. 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 well. Put cooled muffins into 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.

    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!
