  • 2 organic eggs (room temperature)
  • 1/2 cup unsalted butter (room temperature)
  • 10 grams sea salt
  • 1 teaspoon vanilla extract
  • 650 grams organic bread flour
  • 1 cup brown sugar (for filling)
  • 4 tablespoons unsalted butter (for filling, room temperature)
  • 1 tablespoon cinnamon (for filling)

How to Make Sourdough King Cake

Preparing the Dough

Start by combining warm water and sourdough starter in a small bowl. In another bowl, sift together the flour and sea salt. In a large bowl, cream the unsalted butter, vanilla extract, and organic cane sugar until the mixture is light and fluffy. Incorporate the eggs thoroughly, then mix in the warm water and sourdough starter until smooth.

Making the Filling

While the dough is resting, prepare the filling. Use a hand mixer to combine the room temperature butter, brown sugar, and cinnamon until well blended. The aroma of cinnamon will make your kitchen feel cozy and inviting.

Shaping the Cake

After letting the dough rest for an hour, stretch and fold it into a smooth ball. Cover it and let it rise at room temperature for about 2 hours, until it nearly doubles in size. Next, roll the dough into a rectangle on a floured surface, about 15×10 inches, and spread the cinnamon filling evenly over it. Roll the dough tightly from the longer side to form a log, then connect the ends to create a circle in the lined baking pan.

Baking the Cake

Allow the shaped dough to rise for 1 to 2 hours until it puffs up beautifully. Preheat your oven to 375°F (190°C) and bake for 40 minutes, or until the cake is golden brown and fragrant. Let it cool for 2 to 3 hours before icing.

Icing and Decorating

For the icing, mix powdered sugar with milk to achieve your desired thickness. Spread or drizzle this sweet icing over the cooled cake and sprinkle with festive decorations while the icing is still wet for that perfect finish.

Tips for Perfect Sourdough King Cake

Ensuring Your Sourdough Starter is Active

Make sure your sourdough starter is active and bubbly before starting. For an extra boost, mix in a teaspoon of instant yeast to enhance the rise.

Vegan Substitutions

If you prefer a vegan option, substitute eggs with flaxseed meal and use plant-based butter in the dough and filling. Royal icing should be made with whole milk for the best results, but you can find starch-based recipes for a vegan icing alternative.

Storage Suggestions

This cake is best enjoyed fresh, but if you have leftovers, refrigerate them to maintain taste and texture. Reheat slices gently in the microwave for a warm treat.

What is the King Cake Tradition?

Historical Significance

The king cake tradition dates back centuries, originally linked to the Christian celebration of Epiphany. Traditionally, a small figurine or bean is hidden inside, and the person who finds it is crowned king or queen for the day.

Celebrating with King Cake

In many cultures, especially during Mardi Gras, king cakes are a symbol of festivity and joy. Sharing this cake with family and friends is a delightful way to embrace the season.
