Step‑by‑Step Instructions
- Preheat your oven to 350℉ (175℃) and prepare a muffin tin with large bakery-style liners.
- Combine brown sugar, flour, and ground cinnamon in a mixing bowl. Add melted butter and mix until crumbly. Set aside.
- Cream softened butter and white sugar until light and fluffy. Mix in vanilla, eggs, milk, and sourdough until well combined.
- Incorporate baking powder and all-purpose flour into the wet ingredients. Mix until just combined.
- Fill the muffin liners halfway with batter and sprinkle with cinnamon sugar filling.
- Top with remaining batter, filling to three-quarters full, then sprinkle with leftover cinnamon sugar mixture.
- Bake for 25-30 minutes until golden brown and a toothpick comes out clean.
- Cool in the tin for 5 minutes, then transfer to a wire rack.
- Whisk powdered sugar, vanilla, and milk to create glaze. Drizzle over cooled muffins.
- Allow glazing to set before serving.

Notes
Use large bakery-style liners for best results. Avoid overmixing for fluffy muffins. Store in an airtight container for up to 5 days at room temperature.
