# Cooking Steps:
01 - Preheat oven to 350°F. Line a 24-cup mini muffin tin with paper liners or lightly grease the cups.
02 - In a medium 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 well incorporated.
04 - Add the wet ingredient mixture to the dry ingredients and stir just until combined. Do not overmix; some lumps are acceptable.
05 - In a small bowl, mix melted butter, packed light brown sugar, and ground cinnamon until a spreadable paste forms.
06 - Spoon approximately 1 tablespoon of batter into each muffin cup. Top each portion with about 1/2 teaspoon of cinnamon filling, then gently swirl with a toothpick to create a marble effect.
07 - Bake for 16 to 18 minutes, or until a toothpick inserted into the center of a cupcake emerges clean.
08 - Allow cupcakes to rest in the pan for 5 minutes, then transfer to a wire rack to cool completely before glazing.
09 - Whisk together powdered sugar, milk, and vanilla extract until the glaze reaches a smooth, pourable consistency.
10 - Drizzle glaze over the cooled cupcakes. Immediately sprinkle alternating bands of green, purple, and gold sanding sugar across the glaze for traditional King Cake appearance. Allow glaze to set completely before serving.
