Ingredients & Substitutions

Room Temperature Ingredients:ย Room temperature ingredients (specificallyย butter, sour cream, egg, and milk) are important here to prevent lumps in this muffin batter.

Sour Cream: Adding sour cream to the muffin batter helped make the muffins tender and rich.

Lemon: You will need one lemon for this recipe. First, zest the lemon until you have 2 teaspoons. Then, juice the lemon for 2 tablespoons of freshly squeezed lemon juice.

Blueberries: Fresh blueberries are best in this recipe. However, you could also use frozen blueberries to fold into the muffin batter.

Crumble Topping: The crumble topping is easy to make, but really adds something amazing to these muffins.

Glaze (Optional): The simple confectionersโ€™ sugar glaze is made with just two ingredients, confectionersโ€™ sugar (also known as icing sugar or powdered sugar) and water. Add water as needed to get the glaze to your desired consistency. You could leave off the glaze if preferred, as I did in the images.

Can I Make This Into A Loaf?

Yes! If you would rather make these muffins into one loaf, just grab an 8 1/2 x 4 1/2-inch loaf pan to use. Follow the same instructions for the batter and crumble topping. But, bake for 65 minutes (rather than just 20 minutes for muffins). Drizzle the glaze over the top of the cooled loaf.

Can I Make Muffins Ahead Of Time?

Yes, you can make this blueberry lemon muffin batter ahead of time by combining all the ingredients, except for the blueberries, covering, and storing it in the refrigerator overnight. The next day, fold in the blueberries and proceed with baking the muffins. Itโ€™s important to note that the batter should be used within 24 hours for best results, but can be stored up to 48 hours in the refrigerator. You can also get the crumble topping made in advance and stored in the refrigerator for up to a week.

How To Store Blueberry Lemon Muffins

  • Room Temperature: Because they are best enjoyed at room temperature, this is usually the recommended way to store muffins. Use a larger sealable plastic bag or an airtight container to store the muffins in a single layer. Some folks recommend adding a piece of paper towel to the bottom so that it will soak up any condensation. If your muffins are properly cooled before storing, this may not be necessary. However, if I am using an airtight container, I will often add a piece of bread to the container, torn in half, and fit in between the muffins. The bread will soak up moisture as well. Best enjoyed within 2-3 days.
  • Refrigerator: (Refrigeration, in general, dries out baked goods faster so a typical muffin recipe shouldnโ€™t be refrigerated.) Place in a sealable plastic bag or airtight container and then place into the refrigerator. They should keep for up to 5 days. To reheat, remove from refrigerator and pop into the microwave for 10 seconds or just allow muffin to come to room temperature naturally, about 15 minutes.
  • Freezer: Place cooled muffins into a freezer-safe sealable plastic bag or a freezer-safe airtight container and pack as closely as possible without crushing. Remove as much air as possible. Label with date and recipe name. They will last up to 3 months in the freezer.

I am usually just a 'top of the muffin' eater, but I seriously devoured the entire muffin! I loved the texture and all of the blueberries loaded in each muffin. And, even though I am not always a fan of blueberry lemon treats, this one was amazing!

Bella

This muffin is perfectly moist! Exactly how I like my muffins! After each bite, I enjoy biting into a fresh blueberry. Although I am not a huge fan of crumbles on muffins, they work perfectly in this recipe!

This recipe is loaded with fresh lemon and plump blueberries. The muffins are tender and the topping has the perfect buttery crunch!!!

Blueberry overload!! If you love blueberries, and moist muffins, this is it! The hint of lemon and crunchy crumble on top is just perfection.

  1. Will frozen blueberries do
    Ty for all your great recipes I make slit of them for my husbandโ€™s coworkers

    1. Hi Ora – This is what it says in the blog post. Feel free to glance at it should you have questions in the future.
      “Blueberries: Fresh blueberries are best in this recipe. However, you could also use frozen blueberries to fold into the muffin batter.”

  2. I made these muffins and they were so good! I used Greek yogurt lite in place of the sour cream. They were moist and really good. You have got to try them.

    1. Hey! If you donโ€™t mind, when the recipe asks to โ€œbeat until creamyโ€ for the muffin, about how long did that take you? And are we talking just combined or like icing creamy? If you do happen to see this, thanks in advance. Happy baking ๐Ÿ‹๐Ÿง

  3. I didn’t have any sour cream, but had Lemon yogurt in the fridge, so I substituted. They turned out great! Love how moist they are, and the crumble topping is perfect with these. I also have larger muffin pans, so it took a little longer to bake, (approximately 14 minutes more overall) but well worth the wait!๐Ÿฉท
