This Mardi Gras King Cake features a tender, sweet brioche dough enriched with butter and eggs, gently swirled with a cinnamon sugar filling. After rising twice for softness, it's baked to a golden brown and finished with a glossy icing, then brightly decorated with purple, green, and gold sugars to celebrate tradition. The rich, aromatic nutmeg and vanilla add warmth, while the optional lemon zest brightens the flavor. This treat pairs wonderfully with coffee or chicory café au lait, making it a festive staple for gatherings and celebrations.

The first Mardi Gras I spent in New Orleans, my upstairs neighbor Miss Marie knocked on my door with a cardboard box tied with purple ribbon. Inside sat this magnificent ring of brioche, still warm from her oven, with sugar crystals catching the afternoon light through her window. She told me king cake wasn't just dessert it was the season itself, baked into something you could hold in your hands.

Last year I made three of these cakes back to back one for my office, one for my daughters class, and one that never actually made it out of my kitchen. The third one sat on my counter while I debated delivering it, and somehow between morning coffee and afternoon tea, wed picked away half the ring. Sometimes the best parties are the unexpected ones.

Ingredients

  • All purpose flour: This provides structure for the rich dough while keeping it tender, and bread flour would make it too chewy for a traditional king cake
  • Warm milk: Activating the yeast properly is everything here too cold and it wont wake up, too hot and youll kill it before it can work its magic
  • Active dry yeast: One standard packet gives you that reliable rise that creates the airy texture you want in a good brioche
  • Granulated sugar: Sweetens the dough itself while also helping feed the yeast for a strong, steady rise
  • Unsalted butter: Softened butter incorporates into the dough beautifully, creating those tender rich layers that make brioche so special
  • Large eggs: These add richness and structure while helping the dough hold its shape through the rolling and rising process
  • Salt: Just enough to balance the sweetness and bring all the flavors forward
  • Ground nutmeg: A subtle warmth that hints at the festive nature of this traditional cake
  • Vanilla extract: Rounds out all the flavors and adds that classic bakery aroma while it bakes
  • Lemon zest: Optional but lovely, it adds a bright note that cuts through the richness of the butter and sugar
  • Brown sugar: The molasses in brown sugar creates a deeper, more caramel like filling than white sugar alone would give you
  • Ground cinnamon: The classic pairing that makes the house smell like every good memory youve ever had
  • Powdered sugar: Creates that smooth pourable icing that sets up just enough to hold the colored sugars in place
  • Colored sugars: Purple for justice, green for faith, gold for power the colors that tell everyone exactly what season it is
  • Plastic baby: Tucking this inside continues the tradition that whoever finds it hosts next years celebration

Instructions

Wake up the yeast:
Combine the warm milk and yeast in a small bowl, watching for that beautiful foam to form after about five minutes, which tells you the yeast is alive and ready to work
Cream the butter and sugar:
Beat them together until theyre pale and fluffy, then add your eggs one at a time so they incorporate fully before mixing in the salt, nutmeg, vanilla, and lemon zest
Bring the dough together:
Pour in that foamy yeast mixture, then gradually add the flour, mixing until a soft smooth dough forms that feels alive under your hands
First rise:
Place the dough in a greased bowl, cover it with a warm towel, and let it double in size for about ninety minutes while you catch up on that book youve been meaning to read
Prepare the filling:
Stir together the brown sugar and cinnamon in a small bowl until theyre completely combined and ready to create those beautiful spiraled layers
Roll and fill:
Punch down that puffy dough, roll it out on a floured surface into a rectangle, brush it generously with melted butter, and sprinkle every inch with your cinnamon sugar mixture
Shape the ring:
Roll the dough into a tight log from the long side, pinch the seam closed, then form it into a ring on your parchment lined baking sheet and pinch the ends together securely
Second rise:
Cover the ring and let it puff up again for thirty to forty five minutes, tucking in the plastic baby from underneath if youre keeping with tradition
Bake until golden:
Slide it into a 350 degree oven for twenty five to thirty minutes, watching for that gorgeous deep golden brown color that tells you its done
Make the icing:
Whisk together the powdered sugar, milk, vanilla, and salt until you have a smooth pourable consistency that will coat the top of the cake perfectly
Add the colors:
Drizzle the icing over your completely cooled cake, then immediately shower it with alternating sections of purple, green, and gold sugars while the icing is still wet

My cousin found the baby one year at our family party and took her hosting duties so seriously that she started planning next years celebration before shed even finished her slice. Thats the thing about traditions they have a way of taking on a life of their own, one piece of cake at a time.

Making It Your Own

Ive discovered that swapping half the milk for sour cream creates an incredibly tender crumb that people will ask about long after the party ends. Some years I do a cream cheese filling instead of cinnamon sugar, letting the doughs natural sweetness shine without competing with too much spice.

The Serving Ritual

Theres something perfect about cutting this cake with a table full of people watching, wondering whos going to bite into that piece of plastic and become next years host. Serve it with strong chicory coffee if you can find it, or regular coffee if you cant, and let the conversation flow as naturally as the second round of servings.

Timing Your Celebration

The best king cakes appear right after Epiphany and continue through Fat Tuesday, the rhythm of the season dictated by this humble dough ring appearing on breakroom tables and kitchen counters.

  • The dough needs those two rising periods, so plan accordingly and dont try to rush them
  • This cake is actually better the day after its baked, once the flavors have had time to settle and the icing has set up properly
  • If youre transporting it, wait until you arrive to add the final colored sugar decoration so it arrives picture perfect

Recipe FAQs

Use warm milk around 110°F and fresh active dry yeast. Let the yeast mixture sit until foamy before mixing, and keep the dough in a warm, draft-free spot while rising.

Yes, cream cheese or fruit preserves can replace the cinnamon sugar for a different flavor twist while maintaining the cake's moist texture.

Traditional colored sugars in purple, green, and gold reflect Mardi Gras colors, adding a festive look and a touch of sweetness on the icing.

Lightly flour your work surface and rolling pin. If needed, use a small amount of softened butter on your hands and surface to prevent sticking while rolling and shaping.

Instructions

1
Prepare the Dough: Combine warm milk and yeast in a small bowl. Let stand 5 minutes until foamy. In a large mixing bowl, beat butter and sugar until light and fluffy. Add eggs one at a time, then mix in salt, nutmeg, vanilla, and lemon zest. Add the yeast mixture, then gradually mix in flour.

Shape the Cake: Punch down the risen dough and roll out on a floured surface to a 10x20-inch rectangle. Brush melted butter over the surface. Sprinkle evenly with cinnamon-sugar mixture. Starting from the long side, roll up the dough into a log. Pinch the seam to seal. Transfer log to a parchment-lined baking sheet and form into a ring, pinching ends together. Cover and let rise until puffy, about 30–45 minutes. Optionally tuck the plastic baby into the dough from underneath before baking.
