Ingredients

Dough

Cinnamon Filling

Frosting

Instructions

Prepare the Dough

  • Heat the milk and butter together in a microwave-safe bowl until the butter is melted and the mixture is warm, about 60–90 seconds.
    1 cup milk, ¼ cup salted butter
  • Stir in the salt and set aside to cool until just warm to the touch (about 120°F–130°F).
    1¼ teaspoons kosher salt
  • In a separate bowl, combine the warm water, about 1 tablespoon of the sugar, and the yeast. Stir and let stand 5–10 minutes, until foamy.
    ⅔ cup warm water, ½ cup granulated sugar, 1 tablespoon active dry yeast
  • Add the milk mixture, remaining sugar, eggs, and vanilla to the yeast mixture.
    2 large eggs, 2 teaspoons vanilla bean paste
  • Mix in 1 cup of the flour until combined.
  • Continue adding flour, about 1 cup at a time, mixing and kneading until a very soft dough forms and begins pulling away from the sides of the bowl. Add the remaining ½ cup flour only if the dough is excessively sticky.
    5 to 5½ cups all-purpose flour
  • Knead with a dough hook on medium speed for about 5 minutes, or knead by hand for 8–10 minutes, until smooth and elastic.
  • Shape the dough into a ball, place in a lightly oiled bowl, turn to coat, and cover.
  • Let rise in a warm place until doubled in size, 1–2 hours.

Make the Cinnamon Filling

  • Combine the brown sugar, granulated sugar, flour, cinnamon, and melted butter in a bowl.
    ⅔ cup brown sugar, ⅓ cup granulated sugar, ½ cup all-purpose flour, 2 teaspoons ground cinnamon, 4 tablespoons salted butter
  • Mix until evenly blended and crumbly.
  • Set aside.

Shape the King Cakes

  • Line two baking sheets with parchment paper.
  • Punch down the risen dough and divide it in half.
  • Roll one half into a rectangle approximately 10 × 16 inches on a lightly floured surface.
  • Cut the rectangle lengthwise into two long strips.
  • Sprinkle the cinnamon filling evenly over both strips.
  • Roll each strip tightly into a log, seam side down.
  • Twist the two logs together to form a braid, then shape into an oval and pinch the ends to seal.
  • Transfer to a prepared baking sheet.
  • Repeat with the remaining dough and filling.
  • Cover loosely and let rise until puffy, 30–45 minutes.

Bake

  • Preheat the oven to 350°F.
  • Bake the king cakes for 25–30 minutes, until golden brown and baked through.
  • An internal temperature of 190°F–195°F indicates doneness.
  • Cool completely before frosting.

Prepare the Frosting

  • Whisk together the powdered sugar, milk, melted butter, lemon juice, and vanilla until smooth.
    2 cups powdered sugar, 3 tablespoons milk, 1 tablespoon salted butter, 1 teaspoon lemon juice, 1 teaspoon vanilla bean paste
  • Adjust with additional milk if needed to achieve a thick but pourable consistency.

Finish and Serve

  • Insert a small plastic baby into the underside of each cake, if using.
  • Drizzle the frosting over the cooled cakes and spread gently if needed.
  • Decorate with purple, green, and gold sanding sugar while the frosting is still wet.
    ½ cup Purple Sanding Sugar, ½ cup Green Sanding Sugar, ½ cup Gold Sanding Sugar
  • Slice and serve.

Notes

Substitutions
  • Unsalted butter may be used; increase salt by ¼ teaspoon in the dough.
  • If dough is too sticky, begin adding more flour ¼ cup at a time until the desired consistency is reached.
  • Vanilla extract can replace vanilla bean paste in equal amounts.
  • Instant yeast may be substituted for active dry yeast; mix it directly with the flour and sugar and proceed without proofing.
Serving Suggestions and Pairings
  • Serve with coffee, café au lait, or hot chocolate.
  • Pairs well with fresh fruit or any brunch offerings.
Storage
  • Store covered at room temperature for up to 2 days or refrigerate for up to 1 week.
  • Bring to room temperature before serving for best texture.
Freezing
  • Fully baked and unfrosted king cakes may be frozen for up to 2–3 months.
  • Wrap tightly in plastic wrap and place in an airtight container.
  • Thaw at room temperature, then frost and decorate before serving.
