Ingredients:
Muffin Batter:
- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 eggs, room temperature
- 1/2 cup sour cream
- 1/4 cup buttermilk
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1 tablespoon baking powder
- 1/2 teaspoon salt
Cinnamon Sugar Swirl:
- 1/2 cup brown sugar
- 2 teaspoons ground cinnamon
- pinch of salt
Buttery Crumb Topping:
- 1/3 cup brown sugar
- 3/4 cup all purpose flour
- 2 teaspoons ground cinnamon
- 6 tablespoons butter, melted
Finishing Glaze:
- 1.5 cups powdered sugar
- 1 teaspoon vanilla extract
- pinch of salt
- 2–3 tablespoons milk
Directions:
- Preheat oven to 425°F. Grease 10 standard size muffin tins and line with cupcake liners and set aside.
- In a large mixing bowl, make the muffin batter. Combine the melted butter and granulated sugar, beating until combined. Add the eggs in one at a time. Add the sour cream, buttermilk, and vanilla extract.
- Add the flour, baking powder, and salt. Mix until it begins to come together (not fully incorporated). Set aside.
- Next, make the cinnamon sugar swirl and the crumb topping. In a small bowl, combine all of the ingredients for the cinnamon sugar swirl. Stir to combine and set aside.
- In a third separate bowl, combine all of the dry ingredients for the buttery crumb topping. Add the melted butter and mix together until the mixture clumps together. Set aside.
- Use a 2 tablespoon scoop (or 1/8 measuring cup) to drop muffin batter into prepared muffin tins. Next, drop a large spoonful of the brown sugar mixture over the muffin batter. Top the brown sugar another 2 tablespoons of batter to fill the muffins up about 3/4 of the way.
- Top each muffin with a large spoonful of buttery crumb topping, gently pressing into the top of the muffin so that it sticks.
- Bake for 5 minutes at 425°F, then turn oven down to 375°F and bake for an additional 15 minutes, until muffins are golden brown and spring back to the touch. Remove from oven and allow to cool for at least 15 minutes.
- While the muffins cool, make the glaze. Combine all of the glaze ingredients in a bowl and whisk together until smooth. Drizzle the glaze over the crumb topping. Enjoy!
