Lemon Blueberry Muffin Recipe
This updated version of my lemon blueberry muffins improves texture and color while simplifying the method. After testing and retesting, this recipe produces muffins that are lighter, softer in the middle, and nicely golden on top — without extra fuss.
Key ingredients and why they matter
- 1/2 cup unsalted butter — Beaten with sugar to incorporate air and improve texture. Use softened (not melted) butter.
- 3/4 cup granulated sugar — Balances the tartness and helps create a golden top.
- 2 large eggs — Contribute structure and tenderness.
- 1 1/2 teaspoons vanilla extract — Adds depth to the flavor.
- 2/3 cup sour cream — Keeps the crumb soft and moist. This recipe relies on sour cream so you don’t need buttermilk.
- Fresh lemon zest and 2–3 tablespoons lemon juice (about 1 lemon) — Fresh lemon juice and zest deliver bright citrus flavor without harsh tartness.
- 2 cups all-purpose flour — Measure carefully: whisk, spoon into a measuring cup, and level off to avoid dry muffins.
- 1 teaspoon baking powder and 1/2 teaspoon baking soda — The combination gives a reliable rise and a light crumb.
- 1 1/2 cups blueberries — Fresh or frozen. If using frozen, do not thaw; toss with 2 teaspoons of flour to prevent bleeding.
Do not overmix the batter. Overmixing creates tough, dry muffins with tunnels. Use room-temperature eggs and sour cream and softened (not melted) butter to make mixing easier. A few small lumps in the batter are fine.
Bake at 375°F. I found 350°F didn’t produce a strong rise, and 400°F browns the tops too quickly. 375°F gives nicely domed, golden muffins.
The lemon glaze is optional but elevates the muffins. If you prefer less sweetness, skip it.
These muffins are moist, soft in the center, golden on top, and full of lemon and berry flavor. They’re a delightful variation on classic blueberry muffins and make a great breakfast or afternoon snack.
Ingredients
For the Muffins
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened to room temperature
- 3/4 cup granulated sugar
- 2–3 tablespoons lemon zest (about 1 lemon)
- 2 large eggs
- 1 1/2 teaspoons vanilla extract
- 2–3 tablespoons lemon juice (about 1 lemon)
- 2/3 cup sour cream
- 1 1/2 cups blueberries
- 2 teaspoons flour (only if using frozen berries)
For the Glaze
- 1 tablespoon fresh lemon juice
- 1–1 1/2 cups icing sugar
Instructions
Lemon Blueberry Muffins
- Preheat the oven to 375°F. Line a 12-cup muffin pan with paper liners.
- In a large bowl, whisk together the flour, baking powder, baking soda, and salt.
- In a separate large bowl, beat the butter, sugar, and lemon zest until fluffy (about 2–3 minutes).
- Beat in the eggs one at a time, then stir in the vanilla extract and lemon juice.
- With the mixer on low, beat in about half the sour cream, then about half the flour mixture. Beat in the remaining sour cream, then turn the mixer off and gently fold in the remaining flour by hand with a spatula.
- If using frozen berries, toss them with 2 teaspoons of flour in a separate bowl.
- Gently fold the blueberries into the batter.
- Spoon the batter into the prepared muffin pan, filling each cup to the top; you’ll get 12–14 muffins.
- Bake for 17–20 minutes, or until the tops are golden and a toothpick comes out clean or with only blueberry juice (not batter).
- Cool in the pan for 10 minutes, then transfer to a wire rack to finish cooling.
Lemon Glaze
- Whisk the lemon juice and icing sugar together until smooth.
- Drizzle the glaze over cooled muffins.
Notes
*Room temperature ingredients are preferred. To warm eggs quickly, place them in lukewarm water for 10 minutes.
**Fresh or frozen berries both work. I prefer fresh to reduce color bleed. If using frozen, do not thaw; toss with 2 teaspoons flour before folding in. Frozen berries may increase bake time by a few minutes.
***Beating the sour cream and flour into the batter in stages helps prevent overmixing, which makes muffins tough and dry.
Muffins are best the day they’re baked. Store in an airtight container at room temperature up to 3 days, or freeze up to 2 months and thaw in the refrigerator.
