- 1 1/2 teaspoons cinnamon
- 1/4 cup unsalted butter (56 grams) (melted)
Muffin Batter
- 2 cups all-purpose flour (250 grams) (measured properly)
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter (112 grams) (softened, but not melted)
- 3/4 cup granulated sugar (150 grams)
- 1/4 cup brown sugar (50 grams) (light preferred)
- 2 large eggs
- 1 1/2 teaspoons vanilla extract
- 1/2 cup sour cream (120 ml)
- 1/3 cup milk (80 ml) (recommended 2%)
Glaze
- 1/2 cup powdered sugar (55 grams)
- 1-2 tablespoons milk or cream
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) and line a 12-cavity muffin pan with muffin papers.
- Prepare Cinnamon Sugar: Stir together 1/3 cup granulated sugar with 2 teaspoons cinnamon until evenly mixed; set aside for layering.
- Make Streusel Topping: In a bowl, mix 1/2 cup flour, 1/2 cup brown sugar, and 1 1/2 teaspoons cinnamon, then stir in melted butter until the mixture resembles damp sand and forms crumbles.
- Mix Dry Ingredients for Batter: Whisk 2 cups flour, baking powder, baking soda, and salt in a medium bowl to combine evenly.
- Cream Butter and Sugars: In a large bowl, beat softened butter with granulated and brown sugars until the mixture is fluffy and light in color.
- Add Eggs and Vanilla: Mix in vanilla extract, then beat in eggs one at a time, scraping down bowl sides to incorporate completely without lumps.
- Combine Batter Ingredients: On low mixer speed, add half the flour mixture, then sour cream. Follow with the remaining flour mixture and finally milk. Mix just until combined to avoid overmixing.
- Assemble Muffins – Layering: Spoon 1 to 1 1/2 tablespoons of batter into each muffin paper, filling about 1/4 to 1/3 full.
- Add Cinnamon Sugar Layer: Sprinkle the cinnamon sugar evenly over the batter in each muffin cavity.
- Finish Muffin Batter Layer: Spoon about 1 tablespoon of batter over the cinnamon sugar layer; if batter remains, add slightly more so papers are 2/3 to 3/4 full.
- Top with Streusel: Evenly sprinkle the streusel crumble on top of each muffin.
- Bake Muffins: Bake in the preheated oven for 23-27 minutes or until a toothpick inserted into the center comes out clean.
- Cool Muffins: Let muffins cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
- Prepare Glaze: Whisk powdered sugar with 1 tablespoon milk, adding more milk or powdered sugar as needed to achieve a thin drizzle consistency but still opaque white in color.
- Drizzle Glaze: Once muffins are cooled, drizzle the glaze over the tops evenly for a sweet finish.
Notes
- Measure flour properly by spooning into the cup and leveling to avoid dense muffins.
- Do not overmix the batter; mix just until ingredients are combined to keep muffins tender.
- Use 2% milk as recommended for the best texture, but whole milk or cream can add richness.
- The streusel topping can be made ahead and stored in the refrigerator for up to 2 days.
- Adjust glaze thickness by adding milk or powdered sugar gradually for desired drizzle consistency.
