Equipment Needed

• Mixing bowls
• Electric mixer
• Spatula
• Wire cooling rack

Instructions

Step 1: Prepare the Oven and Pan

Preheat oven to:

350°F (175°C)

Grease and line a 9×5-inch loaf pan with parchment paper.

Step 2: Coat the Blueberries

Place blueberries in a bowl.

Toss with:

• 1 tablespoon flour

This helps prevent them from sinking to the bottom during baking.

Set aside.

Step 3: Cream the Butter and Cream Cheese

In a large bowl, beat together:

• Butter
• Cream cheese
• Sugar

Mix for 2–3 minutes until smooth, light, and fluffy.

Step 4: Add Wet Ingredients

Beat in:

• Eggs (one at a time)
• Vanilla extract
• Milk
• Sourdough discard

Mix until well combined.

The batter may appear slightly curdled; this is normal.

Step 5: Mix the Dry Ingredients

In a separate bowl, whisk together:

• Flour
• Baking powder
• Baking soda
• Salt

Gradually add the dry ingredients to the wet mixture.

Mix until just combined.

Do not overmix.

Step 6: Fold in Blueberries

Gently fold the blueberries into the batter using a spatula.

Be careful not to crush them.

Step 7: Add Streusel (Optional)

For a crunchy topping, combine:

• Flour
• Brown sugar
• Cold butter

Rub together until crumbly.

Sprinkle over the batter before baking.

Step 8: Bake

Pour batter into the prepared loaf pan.

Bake at:

350°F (175°C)

For:

55–65 minutes

The loaf is done when:

• The top is golden brown
• A toothpick inserted into the center comes out clean or with a few moist crumbs

Internal Temperature

For best results, the center should reach:

200–205°F (93–96°C)

Step 9: Cool

Allow the loaf to cool in the pan for:

15 minutes

Then transfer to a wire rack.

Cool completely before slicing.

Serving Suggestions

Serve with:

• Softened butter
• Cream cheese
• Honey
• Lemon curd
• Fresh blueberries

Pair with:

• Coffee
• Earl Grey tea
• Iced latte
• Hot chocolate

Tips for Success

Use Room-Temperature Ingredients

This ensures a smoother batter and more even baking.

Don’t Overmix

Overmixing can make the loaf dense instead of tender.

Fresh or Frozen Blueberries

Both work well. If using frozen blueberries, do not thaw before adding.

Check Early

Every oven bakes differently, so start checking around 55 minutes.
