You’ll love how the simple sour cream batter comes together in minutes for a truly impressive treat.

Prep & Cook Time

Prep Time: 10 minutes

Cook Time: 20 minutes

Total Time: 30 minutes

Servings: 18 muffins

Ingredients

• 2 cups flour (*all purpose)
• 3 tsp baking powder
• 1/2 tsp salt
• 2 eggs
• 3/4 cup sugar
• 1 cup sour cream
• 1 tsp vanilla powder (use half this amount if you prefer less rich vanilla flavor)
• 1/2 cup vegetable oil
• 2 1/2 cups blueberries, divided
• 1 tbsp flour
• 1 cup flour (*all purpose)
• 2/3 cup sugar
• 1/2 cup butter, melted
• 1 tsp cinnamon
• 1/2 tsp nutmeg

Instructions

1. Preheat your oven to 400°F (200°C) and line 18 muffin cups with paper liners or grease them well.
2. In a medium bowl, whisk together the first 2 cups flour, baking powder, and salt. Set aside.
3. In a large mixing bowl, whisk the eggs and 3/4 cup sugar together until smooth and slightly pale. Whisk in the sour cream, vanilla powder (use half this amount if you prefer less rich vanilla flavor), and vegetable oil until just combined.
4. In a small bowl, toss 1 1/2 cups of the blueberries with the 1 tbsp of flour until lightly coated. Gently fold these floured blueberries into the muffin batter.
5. To make the streusel topping: In a separate bowl, stir together the final 1 cup of flour, 2/3 cup sugar, cinnamon, and nutmeg. Pour the melted butter over the mixture and use a fork to mix until crumbly.
6. Divide the muffin batter evenly among the 18 prepared cups. Top the batter with the remaining 1 cup of fresh blueberries, pressing them in lightly. Generously sprinkle the streusel topping over each muffin.
7. Bake for 18-20 minutes, or until a toothpick inserted into the center of a muffin (avoiding a blueberry) comes out clean. Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Variations

• Lemon Zest: Add the zest of one lemon to the wet ingredients for a bright, citrusy twist that complements the blueberries beautifully.
• Mini Muffins: Bake the batter in a mini muffin tin for 10-12 minutes for perfect bite-sized treats.
• Crumb Cake Style: Spread the batter into a greased 9×13 inch pan, add blueberries and streusel, and bake for 30-35 minutes for an easy coffee cake.
• Double Streusel: For extra crunch, press half of the streusel mixture into the batter in the cups before adding the top layer of blueberries and the remaining streusel.

Tips for Success

• Tossing the blueberries in flour helps prevent them from sinking to the bottom of the muffins during baking.
• For the most tender muffins, mix the batter only until the dry ingredients are incorporated; a few lumps are fine.
• Use a cookie scoop or ice cream scoop to evenly and cleanly portion the batter into the muffin cups.
• For extra-large “bakery-style” muffins, fill every other cup in the tin, which allows for more space and a better rise.

Storage & Reheating

Store completely cooled muffins in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. For longer storage, freeze them in a single layer before transferring to a freezer bag for up to 3 months. Reheat in a 300°F oven for 8-10 minutes or in the microwave for 15-20 seconds to restore that fresh-baked warmth.

FAQ

Can I use frozen blueberries?

Why is my streusel topping not crumbly?

If your streusel becomes more like a paste, you may have over-mixed it or your butter was too hot. Aim for a coarse, sandy texture with some larger pebbles.

Can I use muffin liners?

Absolutely. Paper liners help with cleanup and prevent sticking. For easier release, you can also use non-stick baking spray directly on the tin.

My muffins didn’t dome. What happened?

This can be caused by over-mixing the batter, old baking powder, or under-filling the cups. Ensuring your oven is fully preheated and filling cups nearly to the top also promotes a good rise.

Can I use yogurt instead of sour cream?

Yes, plain full-fat yogurt is a good 1:1 substitute for the sour cream in this recipe.

Why bake at 400°F?

The initial high heat helps create a quick rise and a nice dome on the muffin before the outside sets, resulting in a lighter texture.
