There’s something about lemon and blueberry recipes that scream “spring.” These lemon blueberry muffins are no exception!  

The muffins themselves are supremely moist thanks to the combination of oil and sour cream in the batter. To amp up the lemon flavor, I used both lemon juice and lemon zest in the batter. There’s nothing worse than biting into a lemon muffin, only for it to barely taste like lemon! 

If you’re a lemon fiend, you’ll love the simple lemon powdered sugar glaze on top of these muffins. It’s the same type of glaze you’d find on a loaf of lemon bread, but this time I drizzled it all over the muffins. Springtime never tasted this good!

Ingredients for This Recipe 

These lemon and blueberry muffins are made with pantry staples, plus a few special ingredients you may need to make a quick grocery run for. Here’s what goes into this muffin recipe: 

  • All-purpose flour: Spoon and level the flour when measuring it, otherwise you may accidentally measure out too much. 
  • Baking powder: Helps the muffins rise in the oven. 
  • Salt: Balances out the sugar in the batter and enhances the lemon flavor. 
  • Granulated sugar: I used 1 cup of sugar in the batter, which is just enough to sweeten the muffins and balance out the sour lemon juice, but not so much that the lemon flavor is masked. 
  • Sour cream: Makes for the moistest muffins. If you don’t have sour cream, you can substitute plain Greek yogurt. 
  • Oil: Use a neutral oil, like canola or vegetable oil. 
  • Lemons: You’ll be using both the juice and zest of the lemons. Give the lemons a quick rinse under warm water to remove any dirt and bacteria before zesting them. 
  • Eggs: To help bind everything together.
  • Vanilla extract: Pure vanilla extract will give you the best flavor. 
  • Blueberries: You may use fresh or frozen blueberries in this recipe. If using frozen blueberries, do not thaw them, and be sure to gently stir them into the batter so they don’t bleed their color.

How to Make Lemon Blueberry Muffins 

Preheat your oven to 375°F (190°C) and line a muffin pan with 12 liners.

In a large mixing bowl, whisk together the flour, baking powder, and salt. In a separate bowl, whisk together the remaining ingredients.

Add the dry ingredients to the wet and mix until just combined. Gently fold in the blueberries last. 

Divide the batter between the 12 muffin liners, filling each one almost all the way to the top. Bake the muffins until a toothpick inserted in the middle comes out clean.

Once the muffins have cooled completely, make the lemon powdered sugar glaze. The glaze is as easy as whisking the two ingredients together until it reaches your desired consistency. 

For a thicker lemon glaze, add more powdered sugar. For a thinner glaze, add a splash more lemon juice. 

Drizzle the glaze over the muffins, then let them sit for 10 minutes so the glaze has time to set.

Can I Use Frozen Blueberries? 

Yes, you can use fresh or frozen blueberries to make the muffins. If using frozen berries, do not thaw them first. Add them to the batter frozen and stir until just combined, otherwise they could bleed their color into the batter.

Storage Instructions 

Store the lemon and blueberry muffins in an airtight container at room temperature for up to three days. They can also be frozen for up to three months. When ready to eat, thaw overnight in the fridge.

Baking Tips 

  • These muffins are quite lemony as is. However, if you want an even stronger lemon flavor, add extra zest to the batter but NOT extra lemon juice. Adding extra lemon juice may make the batter too runny and could alter the texture of the muffins. 
  • The lemon glaze on top of the muffins is technically optional, but it adds a punch of bright citrus flavor! 
  • If using the glaze, let the muffins cool completely before drizzling it over top. If you try to glaze warm muffins, it will slide right off.
