Instructions

Step 1: Prepare the Oven

Preheat your oven to 425°F (220°C).

Line a jumbo muffin pan with paper liners or grease well.

Step 2: Mix Dry Ingredients

In a large bowl, whisk together:

• Flour
• Baking powder
• Baking soda
• Salt

Set aside.

Step 3: Mix Wet Ingredients

In another large bowl, whisk together:

• Melted butter
• Sugar

until smooth.

Add:

• Eggs
• Sour cream
• Milk
• Vanilla extract

Whisk until fully combined.

Step 4: Combine Wet and Dry Ingredients

Gradually add the dry ingredients to the wet ingredients.

Mix gently until just combined.

Do not overmix.

The batter will be thick.

Step 5: Add the Blueberries

Toss blueberries with 1 tablespoon flour.

Fold them gently into the batter.

This helps prevent the berries from sinking.

Step 6: Fill the Muffin Pan

Divide the batter evenly among the 6 jumbo muffin cups.

Fill each cup nearly to the top.

Press a few extra blueberries onto the surface of each muffin.

Sprinkle generously with sparkling sugar.

Step 7: Bake

Bake at 425°F (220°C) for 5 minutes.

Without opening the oven door, reduce the temperature to 375°F (190°C).

Continue baking for 20–25 minutes.

The muffins are done when:

• The tops are golden brown
• A toothpick inserted into the center comes out clean
• The tops spring back lightly when touched

Step 8: Cool

Allow the muffins to cool in the pan for 10 minutes.

Transfer to a wire rack to cool completely.

Bakery Secret for Tall Muffin Tops

Starting the bake at a high temperature creates a burst of steam that quickly lifts the batter, forming those beautiful oversized muffin domes. Lowering the temperature afterward ensures the centers bake evenly without drying out.

and sprinkle over the tops before baking.

Tips for Perfect Muffins

Use Room Temperature Ingredients

This promotes even mixing and a lighter texture.

Don’t Overmix

Overmixing develops gluten and creates dense muffins.

Coat the Blueberries

A light flour coating helps keep berries suspended throughout the batter.

Fill Muffin Cups Generously

Nearly full muffin cups create the iconic bakery-style appearance.

Storage

Room Temperature

Store in an airtight container for up to 3 days.
