Mardi Gras King Cake Cupcakes

The first time I brought these cupcakes to a Mardi Gras party, someone actually gasped when they saw the purple, green, and gold sugars. It was February in Chicago, gray and slushy outside, but my kitchen looked like a carnival had exploded. My roommate kept stealing the cinnamon sugar swirl mixture before I could even fold it into the batter, which tells you everything you need to know about how addictive this recipe is.

Last year I made three dozen of these for my daughters classroom party and the teacher asked for the recipe before the last child had even finished frosting. Watching six year olds get powdered sugar all over their faces while arguing about who found the hidden almond was worth every single minute of cleanup. The way the cinnamon hits you when you bite through that sweet glaze is absolutely transporting.

Ingredients

• All purpose flour: The structure builder here. Do not pack it down or your cupcakes will be dense instead of fluffy light
• Baking powder: This gives you that beautiful dome. Check the expiration date because old baking powder makes sad flat cupcakes
• Salt: Just a pinch to balance all the sugar and let the vanilla shine through
• Unsalted butter: Use this softened to room temperature. Cold butter creates lumps that never quite disappear into the batter
• Granulated sugar: Sweetens and tenderizes. Cream it thoroughly with the butter until it looks pale and fluffy
• Large eggs: Also at room temperature. Cold eggs can seize up the butter mixture and create weird texture issues
• Vanilla extract: The aroma that makes everyone wander into the kitchen. Pure extract worth every penny here
• Whole milk: Creates moisture and richness. Buttermilk works beautifully too if you want extra tang
• Ground cinnamon: The warm spice that makes these taste like king cake. Freshly opened containers give the best flavor
• Brown sugar: Mixed with extra cinnamon for the swirl. The molasses creates little caramel pockets inside
• Powdered sugar: For that classic glaze. Sift it first or your icing will have lumps no matter how much you whisk
• Colored sugars: Purple green and gold are non negotiable. Look for sanding sugar for extra sparkle

Instructions

Get your oven ready:

Preheat to 350 degrees and line a 12 cup muffin tin with paper liners. This tiny bit of prep makes everything else flow smoothly.

Whisk the dry stuff:

Combine flour baking powder and salt in a medium bowl. Set it aside while you work on the wet ingredients.

Cream butter and sugar:

Beat butter and granulated sugar until light and fluffy. This takes about 3 minutes and is worth every second for texture.

Add eggs and vanilla:

Beat in eggs one at a time then stir in vanilla. The mixture should look glossy and smooth.

Combine everything:

Alternate adding flour mixture and milk beginning and ending with flour. Mix only until combined. Over mixing makes tough cupcakes.

Fold in cinnamon:

Gently incorporate the ground cinnamon by hand. You want subtle ribbons of flavor not uniform color.

Mix the swirl:

Stir brown sugar and cinnamon together in a small bowl. This concentrated mixture creates those gorgeous marbled pockets.

Layer the batter:

Fill liners halfway with batter. Sprinkle cinnamon sugar over each then top with remaining batter.

Create the swirl:

Gently drag a toothpick through each cupcake once. Do not over swirl or you will lose the defined ribbon effect.

Bake until perfect:

Bake 18 to 20 minutes until a toothpick comes out clean. Cool in pan 5 minutes then move to a wire rack.

Make the icing:

Whisk powdered sugar milk and vanilla until smooth and pourable. Add milk one tablespoon at a time to reach perfect consistency.

Glaze and decorate:

Spoon icing over cooled cupcakes. Immediately sprinkle colored sugars in alternating stripes before the glaze sets.

My neighbor started requesting these for her birthday instead of a traditional cake. There is something about that combination of warm cinnamon and sweet glaze that feels like a hug. Last Mardi Gras I found myself eating two for breakfast and not even feeling guilty about it.

Making The Swirl Work For You

The cinnamon sugar ribbon is what makes these special. I have learned that sprinkling it in the middle rather than swirling it throughout the entire batter creates the most beautiful marbled effect. The toothpick technique takes a light hand. One gentle swirl through the center gives you those distinct ribbons that look so impressive when you bite into them.

Icing Like A Pro

Perfect glaze consistency is thick enough to hold its shape but thin enough to pour gracefully. If it is too thick it will look clumpy. Too thin and it runs right off the cupcake. The colored sugars need to be applied immediately. I keep three small bowls set up in order purple then green then gold so I can work quickly and create those classic festive stripes.

The Hidden Treasure Tradition

Hiding a plastic baby or almond inside one cupcake before baking keeps the king cake tradition alive. Just make sure every guest knows about it beforehand. I once forgot to warn someone and they nearly choked on the surprise. Now I tuck it into the batter from the side so I can remember which cupcake holds the prize. Watching adults get excited about finding the hidden treasure might be the best part of serving these.

• Press the hidden treasure in horizontally not vertically so it stays hidden during baking
• Use a whole blanched almond if you want to avoid plastic pieces
• Mark your own secret code on the cupcake liner so you know which one contains the surprise
