Use your leftover sourdough discard to make these incredibly soft, fluffy cinnamon rolls. This recipe skips extra yeast and delivers gooey, homemade flavor quickly, topped with a simple cream cheese frosting.

Ingredients

Scale
  • 1 cup (227g) active sourdough discard
  • 1/2 cup (113g) unsalted butter, softened, divided
  • 1/2 cup (100g) granulated sugar
  • 1/4 cup (50g) packed light brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 2 1/2 cups (300g) all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 cup (57g) butter, melted (for filling)
  • 1/2 cup (100g) packed light brown sugar (for filling)
  • 2 tablespoons ground cinnamon (for filling)
  • 4 ounces (113g) cream cheese, softened (for glaze)
  • 1/4 cup (57g) unsalted butter, softened (for glaze)
  • 1 1/2 cups (180g) powdered sugar (for glaze)
  • 1 teaspoon vanilla extract (for glaze)
  • 12 tablespoons milk or cream (for glaze)

Instructions

  1. Combine the sourdough discard, 1/4 cup softened butter, granulated sugar, brown sugar, egg, and vanilla extract in a large bowl. Mix until just combined.
  2. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until a soft dough forms. Do not overmix.
  3. Turn the dough out onto a lightly floured surface and knead briefly, about 1 minute. Cover the dough and let it rest for 10 minutes.
  4. While the dough rests, prepare the filling: In a small bowl, mix the 1/4 cup melted butter, brown sugar, and cinnamon until it forms a thick paste.
  5. Roll the rested dough into a large rectangle, about 12×18 inches. Spread the cinnamon-sugar filling evenly over the dough, leaving a small border on one long edge.
  6. Starting from the long edge opposite the border, tightly roll the dough into a log. Pinch the seam closed.
  7. Slice the log into 12 equal rolls. Place the rolls in a greased 9×13 inch baking dish. Cover the dish loosely with plastic wrap.
  8. Let the rolls rise in a warm spot for 1 to 1.5 hours, or until they look slightly puffy. They will not double in size like traditional yeast rolls.
  9. Preheat your oven to 375°F (190°C). Bake the rolls for 20 to 25 minutes, or until golden brown.
  10. While the rolls bake, prepare the glaze: Beat the softened cream cheese and 1/4 cup softened butter until smooth. Gradually beat in the powdered sugar and vanilla extract. Add milk or cream, one tablespoon at a time, until you reach a spreadable consistency.
  11. Remove the rolls from the oven and immediately spread the cream cheese glaze over the warm rolls. Serve warm for the best gooey texture.

Notes

  • For zero waste baking, this recipe is ideal for using up unfed starter.
  • If you prefer a less tangy flavor, use discard that is closer to 12 hours old.
  • You can prepare the rolls the night before, cover them, and refrigerate. In the morning, let them sit at room temperature for 30 minutes before baking as directed.
