Get ready for a baking adventure that’s both simple and incredibly rewarding, yielding sourdough discard cinnamon rolls fluffy that are incredibly moist and bursting with flavor. This recipe beautifully balances the tang of sourdough with buttery dough and a perfectly spiced, sweet filling, all topped with a luscious cream cheese frosting.

Step-by-Step Instructions
- Activate the Dough: In a large mixing bowl, combine the active sourdough starter, lukewarm milk, granulated sugar, melted butter, egg, and vanilla extract. Whisk until well combined.
- Add Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
- Combine and Knead: Gradually add the dry ingredients to the wet ingredients, mixing with a spoon or dough hook until a shaggy dough forms. If using a stand mixer, switch to the dough hook and knead on low speed for 7-10 minutes, or until the dough is smooth and elastic. If kneading by hand, turn the dough out onto a lightly floured surface and knead for 10-15 minutes. The dough should be slightly tacky but not stick excessively to your hands.
- First Rise: Lightly grease a clean bowl with butter or cooking spray. Place the dough in the bowl, turning to coat. Cover tightly with plastic wrap or a damp kitchen towel. Let the dough rise in a warm place for 1 to 2 hours, or until it has increased in volume by about 50%. This rise is primarily for flavor development and to incorporate air; it won't necessarily double.
- Chill the Dough: Once the dough has had its first rise, gently punch it down. Then, cover the bowl again and refrigerate for at least 30 minutes, or up to overnight. Chilling makes the dough easier to handle and roll out, and it further enhances the flavor.
- Prepare the Filling: While the dough is chilling, prepare the filling. In a small bowl, combine the softened butter, packed light brown sugar, and ground cinnamon. Mix with a fork until a thick paste forms.
- Roll Out the Dough: Lightly flour your work surface and the top of your dough. Roll out the chilled dough into a rectangle approximately 12×18 inches (30×45 cm) and about 1/4 inch thick.
- Spread the Filling: Evenly spread the cinnamon-sugar filling over the rolled-out dough, leaving about a 1/2 inch border along one of the long edges.
- Roll the Dough: Starting from the long edge opposite the border you left, tightly roll up the dough to create a log. Pinch the seam to seal it.
- Slice the Rolls: Use a sharp knife or unflavored dental floss to cut the log into 12 equal cinnamon rolls. To use floss, slide it under the log, cross the ends over the top, and pull to slice cleanly.
- Second Rise (Proofing): Grease a 9×13 inch baking dish with butter. Arrange the sliced cinnamon rolls in the prepared baking dish, cut-side up, leaving a little space between them as they will expand. Cover the dish loosely with plastic wrap or a damp kitchen towel. Let the rolls rise in a warm place for another 45-60 minutes, or until they look puffy and are touching each other.
- Preheat Oven: While the rolls are proofing, preheat your oven to 375°F (190°C).
- Bake the Rolls: Remove the plastic wrap and bake for 20-25 minutes, or until the tops are golden brown and the centers are cooked through.
- Make the Frosting: While the rolls are baking, prepare the cream cheese frosting. In a medium bowl, beat the softened cream cheese and softened butter together until smooth and creamy. Gradually add the sifted powdered sugar and vanilla extract, beating until well combined and fluffy. If the frosting is too thick, add 1-2 tablespoons of milk or cream until it reaches your desired consistency.
- Frost and Serve: Once the cinnamon rolls are out of the oven and still warm, generously spread the cream cheese frosting over the top. Let them cool slightly before serving and enjoy your sourdough discard cinnamon rolls fluffy!

Storing and Reheating Tips
Storing Leftovers:
- At Room Temperature: Covered tightly with plastic wrap or in an airtight container, the cinnamon rolls will stay fresh for 1-2 days. It's best to frost them just before serving to prevent the frosting from becoming too soft.
- In the Refrigerator: For longer storage, place cooled cinnamon rolls in an airtight container and refrigerate for up to 4-5 days. The frosting may firm up slightly in the fridge.
Reheating:
- Oven Method (Recommended): To reheat individual rolls or a small batch, place them on a baking sheet and warm in an oven preheated to 300°F (150°C) for 5-10 minutes, or until heated through and the frosting is re-melted and gooey.
- Microwave Method: For a quick reheat, place a roll on a microwave-safe plate and heat in 15-second intervals until warm. Be careful not to overheat, as this can make the dough tough.
Freezing for Future Meals:
- Unfrosted Rolls: Allow the cinnamon rolls to cool completely. Wrap each roll individually in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months.
- To Reheat Frozen Rolls: Thaw overnight in the refrigerator, then reheat using the oven method described above. You can also reheat them directly from frozen in a 300°F (150°C) oven for about 15-20 minutes.
- Frosting: It's best to prepare the frosting fresh when you're ready to serve the thawed rolls for the best texture and flavor.
