# Step-by-Step Guide:
01 - Preheat oven to 350°F. Line a 24-cup mini muffin tin with paper liners or lightly grease each cup.
02 - In a medium mixing bowl, whisk together flour, granulated sugar, baking powder, salt, and cinnamon until evenly distributed.
03 - In a separate bowl, combine milk, melted butter, egg, and vanilla extract. Whisk until the mixture is smooth and homogeneous.
04 - Pour wet ingredients into the dry mixture and fold together just until combined. Avoid overmixing to ensure tender cupcakes.
05 - In a small bowl, mix melted butter, brown sugar, and cinnamon until the mixture reaches a paste-like consistency.
06 - Spoon approximately 1 tablespoon of batter into each prepared muffin cup. Top each with a small dollop of cinnamon filling, then gently swirl with a toothpick to create a marbled effect.
07 - Bake for 16 to 18 minutes, until a toothpick inserted into the center emerges clean and the tops are lightly golden.
08 - Allow cupcakes to rest in the pan for 5 minutes, then carefully transfer to a wire rack to cool completely.
09 - Whisk together powdered sugar, milk, and vanilla extract until the mixture reaches a smooth, pourable consistency.
10 - Drizzle glaze over the cooled cupcakes. Immediately sprinkle alternating bands of green, purple, and gold sanding sugar across each top to achieve an authentic King Cake appearance. Allow glaze to set before serving.
