Ingredients

Dough

  • 150 g active sourdough starter 2/3 cup
  • 122 g whole milk room temperature (1/2 cup)
  • 390 g all-purpose flour 2 3/4 cups
  • 2 large eggs room temperature (2 large eggs)
  • 6 g salt 1 teaspoon
  • 53 g brown sugar 1/4 cup
  • 3 g ground cinnamon 1 teaspoon
  • 1 g ground ginger 1/2 teaspoon
  • 1 g ground nutmeg 1/2 teaspoon
  • 25-30 g grated carrot patted very dry (1/4 cup)
  • 5 g vanilla extract 1 teaspoon
  • 113 g unsalted butter softened (8 tablespoons)

Filling

  • 135 g brown sugar 2/3 cup
  • 8 g ground cinnamon 1 tablespoon
  • 0.5 g ground ginger 1/4 teaspoon
  • 0.5 g ground nutmeg 1/4 teaspoon
  • 113 g unsalted butter softened (8 tablespoons)
  • 50-60 g grated carrots patted very dry (1/2 cup)

Simple Syrup

  • 80 g water 1/3 cup
  • 67 g granulated sugar 1/3 cup

Cinnamon Cream Cheese Frosting

  • 57 g salted butter softened (4 tablespoons)
  • 113 g cream cheese softened (4 oz)
  • 3 g ground cinnamon 1 teaspoon
  • 5 g vanilla extract 1 teaspoon
  • 120 g powdered sugar 1 cup
  • 30-45 g whole milk 2–3 tablespoons, as needed

Instructions

Make the Dough

  • Add all dough ingredients except the butter to the bowl of a stand mixer fitted with a dough hook.
  • Mix on low to medium speed, scraping down the sides as needed, until a shaggy dough forms.
  • Add the softened butter one tablespoon at a time, mixing well between each addition.
  • Increase to medium-high speed and knead for about 7 minutes, or until the dough is smooth and pulling away from the sides of the bowl.
  • Tip: Watch the dough, not the clock.

Bulk Fermentation

  • Cover the bowl and let ferment for 5–8 hours, or until nearly doubled in size.
  • If your kitchen is warm, it will rise faster; if cool, it may take longer.
  • For a slower fermentation, refrigerate overnight.

Make the Filling

  • In a bowl, use a hand mixer to combine butter, brown sugar, cinnamon, ginger, and nutmeg until smooth.

Shape the Babka

  • Roll the dough into a rectangle about 10 inches long.
  • Spread the filling evenly over the dough.
  • Sprinkle grated, patted-dry carrots evenly on top.
  • Roll tightly lengthwise into a log.
  • Chill for 30 minutes to make shaping easier.

Braid the Dough

  • Slice the log lengthwise down the center using a serrated knife.
  • Place the halves cut-side up.
  • Cross one half over the other to form an “X,” then twist them together, keeping the cut layers facing upward for that signature babka look.

Second Rise

  • Transfer to a parchment-lined 9x5-inch loaf pan.
  • Cover and let rise until puffy and about 50% larger, 1–4 hours.

Bake

  • Preheat oven to 350°F (175°C).
  • Bake for about 40 minutes, or until the internal temperature reaches 200–205°F.

Simple Syrup

  • Heat water and sugar together until dissolved.
  • Brush over the warm babka immediately after baking.

Make the Frosting

  • Beat butter and cream cheese until smooth.
  • Add cinnamon, vanilla, and powdered sugar.
  • Mix until combined, adding milk as needed for desired consistency.

Frost and Serve

  • Let cool completely before frosting.
  • Slice and serve.
