Ingredients You’ll Need
For the dough:
- 1 cup active sourdough starter (100% hydration)
- 3 cups all-purpose flour
- ¼ cup granulated sugar
- 1 teaspoon salt
- ½ cup whole milk, warmed
- 6 tablespoons unsalted butter, browned and cooled
- 1 large egg
For the cinnamon swirl:
- ½ cup unsalted butter, melted
- ¾ cup brown sugar
- 2 tablespoons ground cinnamon
For the glaze (optional):
- 1 cup powdered sugar
- 2–3 tablespoons milk or cream
- ½ teaspoon vanilla extract
Step-by-Step Instructions
Step 1: Prepare the Dough
In a large bowl, combine sourdough starter, warmed milk, and browned butter. Stir in sugar, salt, and egg. Gradually add flour and mix until a soft dough forms. Knead for 8–10 minutes until smooth and elastic.
Step 2: First Rise
Place the dough in a greased bowl, cover with a towel or plastic wrap, and let rise in a warm place for 3–4 hours, or until doubled in size.
Step 3: Roll and Add Filling
Roll out the dough on a floured surface into a large rectangle (about 12×16 inches). Brush melted butter over the dough. Mix brown sugar and cinnamon, then sprinkle evenly on top.
Step 4: Shape the Cinnabundts
Starting from the long edge, roll the dough tightly into a log. Slice into 12 equal pieces. Butter and flour mini Bundt pans, then press each dough piece into a pan, filling the ridges.
Step 5: Second Rise
Cover the filled pans and let rise for another 1–2 hours until puffy.
Step 6: Bake
Preheat the oven to 350°F (175°C). Bake the Cinnabundts for 20–25 minutes until golden brown and cooked through. Remove from pans and cool on a wire rack.
Step 7: Glaze (Optional)
Mix powdered sugar, milk, and vanilla until smooth. Drizzle over cooled Cinnabundts for extra sweetness and shine.
Tips for Success
- Brown Butter: Watch carefully to avoid burning. It should be golden brown with a nutty aroma.
- Active Sourdough Starter: Make sure your starter is bubbly and at peak activity for best rise.
- Mini Bundt Pans: If you don’t have mini pans, a muffin tin works too but the shape won’t be the same.
- Don’t Skip the Glaze: It adds sweetness and moisture that perfectly balances the cinnamon.
Serving Suggestions
- Serve warm with a cup of coffee or chai tea.
- Add fresh berries or whipped cream for a decadent brunch.
- Pack in lunchboxes for a special treat.
