Preheat your oven to 350°F (175°C). Grease a mini muffin tin or line it with paper liners.
2. Prepare the Muffin Batter:
In a medium bowl, whisk together the flour, sugar, baking powder, salt, and cinnamon.
In another bowl, whisk together the milk, melted butter, egg, and vanilla extract until well combined.
Pour the wet ingredients into the dry ingredients and stir until just combined. Be careful not to overmix; the batter should be slightly lumpy.
3. Fill the Muffin Tin:
Spoon the batter into the mini muffin tin, filling each cup about 3/4 of the way full.
4. Bake the Muffins:
Bake for 10-12 minutes, or until a toothpick inserted into the center comes out clean and the muffins are lightly golden on top.
Allow the muffins to cool in the tin for about 5 minutes before transferring them to a wire rack.
5. Coat with Cinnamon-Sugar:
While the muffins are cooling, melt the remaining butter in a small bowl.
In a separate small bowl, mix together the sugar and cinnamon for the coating.
Once the muffins have cooled slightly but are still warm, dip each muffin into the melted butter, then roll it in the cinnamon-sugar mixture to coat it thoroughly.
6. Serve and Enjoy:
Let the coated muffins cool completely or serve them while they’re still warm. They’re perfect with a cup of coffee or as an afternoon snack!
