  • Total Time: 33 minutes
  • Yield: 12 muffins 1x

Ingredients

Scale
  • 1/2 cup unsalted butter, melted
  • 3/4 cup granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 tablespoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup milk, room temperature
  • 1/2 cup sour cream, room temperature
  • 3/4 cup granulated sugar (for cinnamon sugar)
  • 1 tablespoon ground cinnamon
  • 1 cup powdered sugar (for glaze)
  • 1 teaspoon milk (for glaze)

Instructions

  1. Preheat oven to 400°F and grease a muffin tin or line with muffin liners
  2. In a medium bowl, sift together flour, baking powder, salt, and sugar
  3. In a large bowl, combine melted butter, eggs, vanilla extract, milk, and sour cream
  4. Pour wet ingredients into dry ingredients and stir until just combined, being careful not to overmix
  5. In a small bowl, mix together sugar and cinnamon for the swirl
  6. Scoop half of the batter into the prepared muffin tin
  7. Sprinkle a generous amount of cinnamon sugar mixture on top of the batter in each cup
  8. Scoop remaining batter on top of the cinnamon sugar
  9. Sprinkle more cinnamon sugar generously on top of each muffin
  10. Bake at 400°F for 5-6 minutes, then reduce temperature to 350°F and bake for 12-13 minutes until a toothpick inserted in the center comes out clean
  11. Allow muffins to cool completely before glazing
  12. For glaze, mix powdered sugar with milk until smooth and drizzle over cooled muffins

Notes

Use room temperature ingredients for best results. Full-fat sour cream produces the softest and fluffiest muffins. Do not overmix the batter to avoid dry, crumbly muffins.
