Soft, moist sour cream blueberry muffins bursting with juicy blueberries and a tender, bakery-style crumb that’s comforting and easy to make at home.

Ingredients

  • 2 cups all-purpose flour
  • 2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 cup sour cream
  • 1/4 cup milk
  • 1 1/2 cups fresh or frozen blueberries

Instructions

  1. Preheat the oven to 375°F (190°C) and line a muffin tin with liners.
  2. In a bowl, whisk together flour, baking powder, baking soda, and salt.
  3. In another bowl, cream butter and sugar until light and fluffy.
  4. Add eggs and vanilla extract and mix until combined.
  5. Stir in sour cream and milk until smooth.
  6. Gently fold the dry ingredients into the wet ingredients until just combined.
  7. Fold in blueberries carefully to avoid overmixing.
  8. Divide batter evenly among muffin cups.
  9. Bake for 20–22 minutes, until tops are lightly golden and a toothpick comes out clean.
  10. Cool slightly before removing muffins from the pan.

Notes

  • Toss blueberries with a little flour to prevent sinking.
  • Frozen blueberries can be used straight from the freezer.
  • Lemon zest adds a bright flavor boost.
  • Sprinkle coarse sugar on top for a crisp muffin top.
