Instructions
- Preheat the Oven: Set oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease it.
- Prepare the Streusel Topping: In a small bowl, mix together flour, granulated sugar, cinnamon, and salt. Add melted butter and vanilla extract, using a fork to create a crumbly texture. Place in the freezer while preparing the batter.

- Assemble the Muffins: Spoon a tablespoon of batter into each muffin cup. Sprinkle with the cinnamon swirl mixture. Add the remaining batter and top with streusel.
- Bake: Bake for 18-22 minutes, or until a toothpick inserted comes out clean. Let cool in the pan for 5 minutes, then transfer to a wire rack.
- Optional Glaze: Mix 1 cup powdered sugar, 2 tablespoons milk, and ½ teaspoon vanilla extract. Drizzle over cooled muffins.
