If I could have any muffin, I would always choose Lemon Blueberry! It’s just the perfect sweetness with a touch of tart. I think the Lord really loved me when he made blueberries. I could eat blueberries all day, every day!

You May Be Wondering What to Do With All Your Sourdough Discard

Make these delicious muffins! Or any of the other sourdough discard recipes on my blog! I love incorporating sourdough into as much of my baking as possible. It’s a delicious way to use up any extra discard. If you are feeding your own sourdough starter every day (sometimes twice a day) like I do, you may have a lot of sourdough starter discard. Don’t actually “discard” it! Quick recipes like this are a great way to use leftover sourdough discard. It adds such great flavor and fluffy texture!

What Kind of Blueberries Should Be Used in These Lemon Blueberry Sourdough Discard Muffin Recipe?

You can use either fresh or frozen. I like to use frozen in muffins, as they are less likely to get smashed when they are combined into the muffin batter. I also prefer to use frozen wild blueberries.

Why Wild Blueberries?

Wild blueberries have a much higher nutritional value than regular blueberries. They are also a lot smaller and less likely to cause texture aversions with kids. (ahem… my kids.) I’m sure I’m not the only mom who has had to deal with that sort of thing when feeding their children. (Blessing to all you fellow picky kids’ mommas. It will get better!)

Can I Use Lemon Juice Instead of Lemon Zest in Lemon Blueberry Muffins?

Yes, you can use 2 tablespoons of lemon juice for 1 tablespoon of lemon zest. Lemon juice is more acidic than lemon rind, though. So you may want to up the sugar just ever so slightly.

How to Keep Blueberries From Sinking in Muffins

If you just dump frozen or fresh blueberries into muffins or quick bread, they will most likely sink to the bottom when they are baked. For best results add a couple of tablespoons of the flour that you will be using in my batter and toss it in with the blueberries. Then fold the flour coated blueberries into the batter after all other ingredients have been added. This will help them to float in the batter. It also helps prevent some bleeding of the blueberries in your batter if you are using frozen blueberries.

Did you know?

The silvery-white coating on blueberries is a sign of freshness. The “bloom” as it is called is natural and helps protect the fruit from insects and bacteria.

How to make Lemon Blueberry Sourdough Discard Muffin Recipe

  • Preheat oven to 425 degrees F and prepare muffin pan with paper liners. This recipe will make 12-15 muffins.
  • In a large mixing bowl, cream together the sugar and room temperature butter. 
  • Next add the eggs, vanilla extract, sourdough discard, sour cream, and lemon zest. 
  • Once combined, add dry ingredients: flour (reserve about 2 Tablespoons to mix in with the blueberries), baking powder, baking soda, and salt to the wet ingredients. Mix just until flour mixture is incorporated into wet ingredients.
  • Coat blueberries with the reserved flour and then fold them gently into the batter. 
  • Fill muffin cups to the top. (I like to use a large cookie scoop to put the muffin batter into the muffin tin.)

How to make crumb topping

  • Soften the butter in a small bowl and mix in brown sugar and flour with a fork.

    This recipe is so good! I’m typically hesitant to follow a recipe without any reviews but these turned out good.

    Only thing I noticed was the crumb topping could’ve used less butter since it turned out more of a batter consistency but still baked fine.

    1. I’m so glad you liked these muffins! I don’t usually like to attach the nutritional values with my recipes because ingredients values can differ and I can’t really give very accurate values for everyone. There are nutritional calculators that you can list ingredients in a recipe and it can give you an idea of the nutritional values. I used one online and plugged in this recipe and here is what it came up…

    Amazing! Such great texture and flavor! I changed it up a bit, did 1/2 butter 1/2 coconut oil, I ran out of reg flour so had to add 1/4 cup of WW flour and I added some chopped strawberries.
    I didn’t do the crumble just to save a few calories. Makes 12 nice size muffins! So yummy!!

    They came out perfectly delicious! Do you think I could use this recipe for a crumb cake instead of muffins?

    1. I have not personally used this muffin recipe for a crumb cake, but I don’t see why you couldn’t. I think I would use a 8×8 or 9×9 pan. Also adjust the oven temperature to 350 and expect to cook it for about 40-45 minutes or until toothpick comes out clean. I’m so glad you liked this recipe!
