How to Make Lemon Blueberry Muffins
Step 1: Prepare the Oven and Pan
Preheat the oven to 425°F.
Line a standard 12-cup muffin pan with paper cases.
Step 2: Combine the Dry Ingredients
Whisk the flour, baking powder, baking soda and salt in a large bowl.
Set the mixture aside.
Step 3: Make Lemon Sugar
Place the granulated sugar and lemon zest in a separate bowl.
Rub them together with clean fingertips until fragrant and slightly moist.
Step 4: Add the Wet Ingredients
Add the eggs, vegetable oil, sour cream, milk, lemon juice and vanilla to the lemon sugar.
Whisk until smooth.

Step 5: Combine the Mixtures
Pour the wet ingredients into the dry mixture.
Fold gently with a spatula until only a few flour streaks remain.
The batter should be thick and slightly lumpy.
Step 6: Prepare the Blueberries
Dry fresh blueberries thoroughly.
Toss the berries with one tablespoon of flour.
Frozen blueberries should remain frozen.
Step 7: Fold in the Blueberries
Add the berries to the batter.
Fold gently until evenly distributed.
Avoid overmixing or crushing the fruit.
Step 8: Fill the Muffin Cups
Divide the batter between the 12 paper cases, filling each nearly to the top.
Add several extra blueberries and optional coarse sugar.

Step 9: Bake at High Temperature
Bake at 425°F for 5 minutes.
Without opening the oven, reduce the temperature to 350°F.
Step 10: Finish Baking
Continue baking for approximately 15–19 minutes.
The muffins are ready when:
- The tops are golden and rounded.
- They spring back when pressed gently.
- A toothpick emerges clean or with several moist crumbs.
Avoid testing directly through a blueberry.
Step 11: Cool
Allow the muffins to cool in the pan for approximately five minutes.
Transfer them to a wire rack.
Serve warm or at room temperature.
Tips for Tall Bakery-Style Muffins
- Begin with a fully preheated oven.
- Fill each case nearly to the top.
- Use thick batter.
- Avoid overmixing.
- Keep frozen berries frozen.
- Bake at 425°F initially, then reduce the temperature.
- Do not open the oven during the temperature change.
Why Are My Muffins Dense?
Dense muffins may result from too much flour, overmixing, cold ingredients, expired raising agents or underbaking.
Measure the flour accurately and fold only until the ingredients are combined.
Why Did the Blueberries Sink?
The batter may be too thin or the berries may be wet. Dry and coat fresh berries lightly with flour before folding them into the thick batter.
Why Did Frozen Blueberries Turn the Batter Purple?
Frozen berries release colour when they begin thawing. Add them directly from the freezer and fold them through the batter with as few movements as possible.

Place a paper towel beneath and above the muffins to absorb excess moisture.
Can You Freeze Lemon Blueberry Muffins?
Yes.
