📝 About This Recipe

Celebrate the spirit of Mardi Gras with this authentic Gâteau des Rois, a regal brioche ring that bridges the gap between old-world French tradition and vibrant Louisiana soul. This recipe features a buttery, yeast-leavened dough swirled with a decadent cinnamon-pecan filling, draped in a silky vanilla glaze, and finished with the iconic purple, green, and gold sugars. It is more than just a dessert; it is a centerpiece of celebration, hidden with a tiny plastic baby to designate the 'king' or 'queen' of the festivities.

🥗 Ingredients

The Brioche Dough

  • 4 cups All-purpose flour (plus more for dusting)
  • 1 cup Whole milk (warmed to 110°F)
  • 1 packet Active dry yeast (0.25 oz)
  • 1/2 cup Granulated sugar
  • 1/2 cup Unsalted butter (melted and cooled)
  • 2 large Egg yolks (room temperature)
  • 1 teaspoon Kosher salt
  • 1/4 teaspoon Nutmeg (freshly grated)

Cinnamon-Pecan Filling

  • 3/4 cup Light brown sugar (packed)
  • 1 tablespoon Ground cinnamon
  • 1/2 cup Pecans (finely chopped)
  • 4 tablespoons Unsalted butter (softened)

Glaze and Decoration

  • 2 cups Powdered sugar (sifted)
  • 2-3 tablespoons Whole milk
  • 1/2 teaspoon Vanilla extract
  • 3 tablespoons Colored sanding sugars (Purple, Green, and Gold/Yellow)
  • 1 piece Plastic baby (to be hidden after baking)

👨‍🍳 Instructions

  1. 1

    In a small bowl, combine the warm milk and 1 tablespoon of the granulated sugar. Sprinkle the yeast over the top and let it sit for about 5-10 minutes until it becomes foamy and fragrant.

  2. 2

    In the bowl of a stand mixer fitted with the dough hook, combine the remaining sugar, melted butter, egg yolks, salt, and nutmeg. Pour in the yeast mixture and whisk by hand until combined.

  3. 3

    Add the flour one cup at a time, mixing on low speed until a soft dough forms. Increase to medium speed and knead for about 5-7 minutes until the dough is smooth, elastic, and pulls away from the sides of the bowl.

  4. 4

    Place the dough in a lightly greased bowl, cover with plastic wrap or a damp cloth, and let rise in a warm, draft-free spot for 1.5 to 2 hours, or until doubled in size.

  5. 5

    While the dough rises, prepare the filling by mixing the brown sugar, cinnamon, and chopped pecans in a small bowl. Set aside the softened butter.

  6. 6

    Punch down the risen dough and turn it out onto a lightly floured surface. Roll it out into a large rectangle, approximately 10x20 inches.

  7. 7

    Spread the 4 tablespoons of softened butter evenly over the dough, leaving a 1-inch border. Sprinkle the cinnamon-sugar-pecan mixture over the butter.

  8. 8

    Starting from the long edge, roll the dough up tightly like a jelly roll. Pinch the seam closed.

  9. 9

    Transfer the log to a parchment-lined baking sheet and join the ends together to form a ring. Dampen the ends with a little water and tuck one end into the other, pinching firmly to seal.

  10. 10

    Cover the ring lightly and let it rise again for 45 minutes until puffy. Preheat your oven to 350°F (175°C) during this time.

  11. 11

    Bake for 25-30 minutes, or until the cake is a deep golden brown. Let the cake cool completely on a wire rack before icing.

  12. 12

    Once cool, make a small slit in the bottom of the cake and insert the plastic baby. In a bowl, whisk together the powdered sugar, milk, and vanilla until smooth and thick but pourable.

  13. 13

    Drizzle the glaze over the cake, then immediately alternate bands of purple, green, and gold sanding sugar over the wet icing.

💡 Chef's Tips

Ensure your milk isn't too hot (above 115°F) or it will kill the yeast; use a thermometer to be safe. For an extra-rich dough, substitute half the milk with heavy cream. If you don't have a stand mixer, you can knead the dough by hand for 10-12 minutes until it passes the 'windowpane test.' Always hide the plastic baby *after* baking to avoid melting it or creating a choking hazard for those unaware. If the dough is too sticky, add flour 1 tablespoon at a time, but avoid over-flouring or the cake will be tough.

🍽️ Serving Suggestions

Serve with a steaming cup of Café au Lait spiked with chicory for the ultimate New Orleans breakfast. Pair a slice with a glass of chilled Champagne or sparkling cider for a festive party vibe. Offer extra pecans and a side of Creole cream cheese for guests who want an even richer experience. Serve as the centerpiece of a brunch spread alongside savory boudin links or a spicy crawfish quiche.
