Ingredients

For the Muffins

  • 1 cup sourdough discard
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup melted butter
  • 3/4 cup sugar
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup milk
  • 1 1/2 cups fresh or frozen blueberries

For the Crumb Topping

  • 1/2 cup flour
  • 1/3 cup sugar
  • 1/4 cup cold butter
  • 1/2 teaspoon cinnamon (optional)

Step-by-Step Instructions

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C).

Line a muffin tray with bakery-style muffin liners or parchment paper cups.

Large muffin liners help create tall bakery-style muffins.

Step 2: Make the Crumb Topping

In a small bowl combine:

  • Flour
  • Sugar
  • Cold butter
  • Cinnamon

Use your fingers or a fork to mix until crumbly.

The topping should look sandy with small buttery chunks.

Place it in the refrigerator while preparing the batter.

Step 3: Mix the Wet Ingredients

In a large bowl whisk together:

  • Melted butter
  • Sugar
  • Eggs
  • Vanilla extract
  • Milk
  • Sourdough discard

Mix until smooth and creamy.

The sourdough discard adds rich flavor and soft texture.

Step 4: Add the Dry Ingredients

In another bowl combine:

  • Flour
  • Baking powder
  • Baking soda
  • Salt

Slowly add the dry ingredients into the wet mixture.

Mix gently until just combined.

Do not overmix or the muffins may become dense.

Step 5: Fold in the Blueberries

Carefully fold the blueberries into the batter.

If using frozen blueberries, do not thaw them first.

This prevents the batter from turning purple.

The batter should be thick and fluffy.

Step 6: Fill the Muffin Cups

Fill each muffin cup almost to the top.

Bakery-style muffins need extra batter for tall domed tops.

Sprinkle generous amounts of crumb topping over each muffin.

The more crumb topping, the better the bakery-style texture.

Step 7: Bake the Muffins

Bake for 22–28 minutes or until golden brown.

The tops should look crisp and beautifully crumbly.

A toothpick inserted into the center should come out mostly clean.

Your kitchen will smell incredible during baking.

Step 8: Cool and Serve

Allow the muffins to cool for 10 minutes before removing from the tray.

Serve warm for the best flavor and texture.

The blueberries will be juicy and the crumb topping perfectly buttery.

Tips for Perfect Bakery Muffins

Don’t Overmix

Overmixing creates tough muffins.

Mix only until the flour disappears.

Use Cold Butter for Streusel

Cold butter creates a crunchy crumb topping.

Fill Muffin Cups Fully

This creates tall bakery-style muffin tops.

Use Fresh Blueberries When Possible

Fresh berries create the best texture and flavor.
