Description

Deliciously moist sour cream blueberry muffins bursting with fresh or frozen blueberries. These muffins have a tender crumb thanks to the sour cream and are topped with a crunchy coarse sugar for a delightful texture contrast. Perfect for breakfast, snacks, or brunch, this recipe yields 16 muffins and requires simple ingredients and straightforward steps.


Ingredients

Scale

Dry Ingredients

  • 3 cups all-purpose flour (spooned and leveled, about 360g)
  • 1 tablespoon baking powder
  • ¼ teaspoon salt

Wet Ingredients

  • 1½ cups full-fat sour cream
  • 2 large eggs
  • ½ cup vegetable oil
  • 1 cup granulated sugar
  • 1½ teaspoons vanilla extract

Fruit

  • 2 cups fresh or frozen blueberries

Toppings (optional)

  • Coarse sugar for sprinkling on top


Instructions

  1. Prep: Preheat your oven to 425°F (218°C). Line 16 muffin cups with paper liners. If you don’t have enough muffin cups, you can use a mini loaf pan for the extra batter.
  2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, baking powder, and salt until well combined.
  3. Mix Wet Ingredients: In a separate bowl or a large measuring jug, whisk the sour cream and eggs until smooth. Add in the vegetable oil, granulated sugar, and vanilla extract, stirring thoroughly until everything is well combined.
  4. Prepare Blueberries: If you’re using fresh blueberries, rinse them under cold water and pat dry. For frozen blueberries, no need to thaw; toss them directly into the flour mixture and coat evenly to prevent them from sinking and bleeding in the batter.
  5. Combine Ingredients: Pour the wet sour cream mixture into the bowl with dry ingredients and blueberries. Gently fold the batter with a spatula until just combined. The batter will be thick—that is the desired consistency.
  6. Fill Muffin Cups: Evenly divide the batter into the prepared muffin cups, filling them nearly to the top. Sprinkle the tops with coarse sugar and press a few extra blueberries on top if you want an attractive bakery-style finish.
  7. Bake: Place the muffin pans in the oven and immediately lower the temperature to 400°F (204°C). Bake for 5 minutes, then reduce the oven temperature again to 350°F (177°C) and bake for an additional 15–18 minutes. Avoid opening the oven during this time. Muffins are done when a toothpick inserted in the center comes out clean.
  8. Cool and Serve: Allow the muffins to cool in the pan for 5–10 minutes. Transfer them to a wire rack to cool completely or serve warm. Store any leftovers in an airtight container.

Notes

  • Use either fresh or frozen blueberries based on what you have available; coating frozen blueberries in flour prevents them from sinking.
  • Coarse sugar sprinkled on top adds a delightful crunch and looks attractive but is optional.
  • Filling mini loaf pans with leftover batter is a great way to avoid waste and enjoy a different texture.
  • Keeping the oven door closed during baking ensures even cooking and puffy muffins.
