Butter on blueberry muffin half

The quintessential muffin. Blueberries belong in muffins like chocolate chips belong in cookies. They just go together. These sourdough discard muffins are perfectly moist in the middle with a tender crumb, golden on top with a crunch from the sparkling sugar tops, all with a lovely blueberry flavor throughout. Perfect in the morning with a cup of coffee, or a glass or milk. They are also good as an afternoon snack. An added bonus, these muffins are really simple to make and are ready in less than an hour. Let’s make Sourdough Blueberry Muffins: A Recipe from the Farm.

The Ingredients for Fluffy Sourdough Blueberry Muffins:

All-Purpose Flour

My Favorite flour to use is Dakota Maid flour. It’s not necessary to use bread flour in this recipe actually it is better not too. Less protein in your flour, to a certain point, makes for a more tender crumb to your muffin.

Salt

You only need a ½ teaspoon of salt in this muffin recipe. There is also salt being added because of the salted butter.

Baking Soda and Baking Powder

It is fun to take out a lofty muffin from the oven. Baking soda and baking powder are partly responsible for this as they are both a leavening agent. I use both to ensure a fluffy high muffin top!

Buttermilk

Buttermilk adds to the texture of these moist muffins. If you don’t have buttermilk, you can make your own with milk and vinegar or lemon juice.

How to make Buttermilk at home:

  • Add 1 T vinegar OR lemon juice per 1 cup of milk.
  • Stir and let sit for 5 minutes.

Eggs

You need two room temperature eggs for this recipe.

Pure Vanilla Extract

Vanilla pairs well with blueberries and adding a couple teaspoons elevates these sourdough discard blueberry muffins.

Sugar

There is enough sugar so that the muffins are sweet but not a cupcake sweet. I went back and forth if I wanted them to have a streusel top or sprinkled with sugar. Honestly in the end the sugar top wins. It is simple, doesn’t add as much fat and calories to the muffin and creates such a beautiful muffin top with the perfect crunch! Yum!

Butter

Make sure your butter is soft and combine it first with the sugar. Then add the rest of the wet ingredients mixing well!

Quick way to get soft butter: You can soften the butter in the microwave using the defrost setting. I always find the defrost setting easier when working with butter because it is easier to not melt it!

Sour Cream

Sour Cream adds moisture to these muffins, like the starter, and buttermilk do.

Sourdough Starter – Active or Discard

This is a great way to use up that sourdough discard! Either active sourdough starter or sourdough discard work for this recipe.

What is sourdough discard? After you have fed your starter and use the active sourdough starter in the recipe you plan to make, sometimes there is more leftover sourdough starter than needed in your jar. This can be saved as sourdough discard and used in recipes like this! Just make sure to leave some (about ¼ cup or 75-100 grams) in the bottom of the jar to feed the next time you want to bake something with sourdough.

If you don’t have your own sourdough starter, Agnes would love to help you learn how. Follow along with her and you will have a young starter in a week!

Frozen Blueberries or Fresh Blueberries

Either way these muffins are delicious. If you are using fresh just wash them and throw them in. Sometimes I will squish a half cup of the blueberries first to help distribute the berries well. This is not necessary though.

Frozen blueberries just take out of the freezer and fold into your batter.

Mixing up the Muffin Batter:

  • For best results, before you start mixing up your muffins make sure your ingredients are at room temperature. This helps the ingredients incorporate better and results in a better muffin.
  • First you measure out all the liquid ingredients and put them in a large mixing bowl. Combine them with a whisk until well combined and then add the sugar and mix again.
  • In a medium mixing bowl add the dry ingredients together and then add to the wet ingredients and stir. Mix until just combined and be sure TO NOT OVERMIX.
  • Fold in the fresh or frozen blueberries and they are ready for the oven!

Why Bake them at a High Temperature to Start?

When baking these muffins, you will start your oven at 400 degrees. The muffins bake at 400 degrees for 10 minutes and then lower the temperature to 350 degrees for the last of the baking time.

This initial high temperature allows the muffins to spring up and have a beautiful muffin top. Finishing them at 350 degrees ensures that they won’t burn on the outside and be raw on the inside.

Jumbo Muffin Variation:

Sometimes I like to make jumbo muffins. Same recipe but different pan and you will bake them a while longer. If you are looking for a more bakery-style muffin this is the way to go!

FAQ’s

How do you know when blueberry muffins are done baking?

There are two ways that are commonly used to check if a muffin is done baking:
Does it spring back when lightly touched?
Does a toothpick inserted into the center come out clean?
If either of these questions are answered yes, then the muffins are done!

Why are my blueberry muffins dry?

Chances are that if you have dry or hard muffins it is because you either overmixed them, over baked them, or both. Make sure to only mix until moistened. It’s okay if there are a few lumps. And take them out on time. Watch them closely towards the end of the bake time.

Can I substitute oil for butter?

Yes, I have made this recipe with oil as well and it works. I would just say the oil makes for a less flavorful muffin.

  1. I’m definitely going to try these soon. I never thought about making jumbo muffins in general, let alone sourdough ones. Now I need to look for a jumbo muffin tin!
