Ingredients

Streusel

  • 1/2 cup all-purpose flour
  • 1/2 cup old-fashioned oats
  • 1/2 cup packed dark brown sugar
  • 3/4 tsp kosher salt
  • 5 tbsp salted butter, cubed and at room temperature
  • 1/4 cup packed dark brown sugar
  • 2 tbsp salted butter, melted and slightly cooled
  • 1 tbsp all-purpose flour
  • 1 tsp ground cinnamon

Muffin Batter

  • 2 cup all-purpose flour
  • 2 tsp baking powder
  • 1/4 tsp baking soda
  • 1/2 tsp ground cinnamon
  • 1/2 tsp kosher salt
  • 1 cup sour cream, at room temperature
  • 1 stick salted butter, melted and slightly cooled
  • 1/2 cup granulated sugar
  • 2 large eggs, at room temperature
  • 1/2 tsp vanilla extract

Glaze

  • 1 cup powdered sugar
  • 1 to 2 tbsp milk (adjust for consistency)

Instructions 

  • Preheat oven to 375˚F. Line a muffin pan with liners. Make streusel: mix flour, oats, brown sugar, salt, and cut in butter until crumbly.
  • Prepare cinnamon swirl: whisk brown sugar, melted butter, flour, and cinnamon. Set aside.
  • Mix dry ingredients for muffins. In another bowl, whisk wet ingredients. Combine gently until just mixed. Fill muffin cups halfway, add cinnamon swirl, top with remaining batter, and sprinkle streusel.
  • Bake 30-32 minutes until golden. Cool 10 minutes in pan, then transfer to rack to cool completely.
  • Whisk powdered sugar and 1 tbsp milk for glaze. Add more milk if needed. Drizzle over cooled muffins and let set for 10 minutes.
