Ingredients
Method
- Heat the oven to 375 F (190 C). Line a 12 cup muffin pan with paper liners.
- Mix the streusel ingredients until large clumps form. Mix the swirl brown sugar and cinnamon in a separate bowl.
- Whisk the flour, sugar, baking powder, baking soda and salt in a large bowl.
- In a second bowl, whisk the egg, sour cream, melted butter, milk and vanilla. Fold the wet mixture into the dry mixture until just combined.
- Add 1 tablespoon of batter to each liner, sprinkle with half of the cinnamon sugar, then add the remaining batter to fill 3/4 full. Sprinkle with the rest of the cinnamon sugar.
- Top each muffin with streusel. Bake for 22 to 25 minutes until golden and a toothpick comes out clean.
- Cool for 10 minutes. Whisk the glaze ingredients and drizzle over the warm muffins.
