You’ll not only solve your discard dilemma but also create the most irresistibly soft, perfectly spiced, and wonderfully balanced cinnamon rolls you’ve ever tasted!

Ingredient Notes

Making Sourdough Discard Cinnamon Rolls is truly a joy, and understanding the role of each ingredient will help you achieve that perfect fluffy texture and irresistible flavor. Here’s a quick run-down of what you’ll need and why:

Sourdough Discard: This is our star! Unlike a fed sourdough starter, discard isn’t here for leavening (we’ll use commercial yeast for that). Instead, it brings a beautiful tang, depth of flavor, and incredible tenderness to the dough. You can use discard straight from the fridge, whether it’s a day old or a week old – the age doesn’t matter much here, as long as it’s unfed.
Active Dry or Instant Yeast: Since the discard isn’t active, commercial yeast is essential for a reliable rise. Instant yeast can be mixed directly with the dry ingredients, while active dry yeast usually needs to be proofed in warm milk first.

All-Purpose Flour: I find all-purpose flour works wonderfully for these rolls, giving them a tender crumb. If you want a slightly chewier roll, you could substitute up to half of it with bread flour.
Whole Milk: Whole milk contributes richness and moisture to the dough, making it soft and tender. You can substitute with 2% milk, but whole milk truly gives the best results. For a non-dairy option, unsweetened almond or oat milk can also work, though the texture might be slightly different.

Granulated Sugar: This provides sweetness to the dough and also helps to activate the yeast.
Unsalted Butter: Butter is crucial for both the dough and the filling, adding richness and flavor. Make sure it’s softened for both the dough and the frosting, and melted for the filling. If using salted butter, reduce the added salt in the dough by about a quarter teaspoon.
Eggs: Eggs add richness, color, and contribute to the overall structure and tenderness of the rolls.

Salt: Don’t forget the salt! It balances the sweetness and enhances all the flavors in the dough.
Brown Sugar & Cinnamon (for the filling): The classic combo! Dark or light brown sugar works equally well, providing that deep, molasses-y sweetness. Use a good quality cinnamon for the best aroma and taste.
Cream Cheese (for the frosting): Full-fat cream cheese is key for a luscious, tangy frosting. Let it soften at room temperature before beating to avoid lumps.

Powdered Sugar (for the frosting): Also known as confectioners’ sugar, this fine sugar dissolves easily to create a smooth frosting.
Vanilla Extract: A touch of vanilla brightens up the frosting beautifully.

Step-by-Step Instructions

Get ready to fill your kitchen with the most amazing aroma! Here’s how I make my Sourdough Discard Cinnamon Rolls:

1. Prepare the Dough

In a large bowl, combine the warm milk (ensure it’s not too hot, about 105-115°F or 40-46°C), sourdough discard, granulated sugar, and yeast. If using active dry yeast, let it sit for 5-10 minutes until foamy.
Add the softened unsalted butter, eggs, and salt to the mixture. Whisk everything until well combined.
Gradually add the all-purpose flour, mixing with a wooden spoon or a stand mixer with a dough hook until a shaggy dough forms.

Turn the dough out onto a lightly floured surface or continue with the dough hook. Knead for 8-10 minutes until the dough is smooth, elastic, and no longer sticky. It should pass the windowpane test (stretch a small piece thinly enough to see light through it without tearing).
Lightly grease a clean bowl with a little oil. Place the dough in the bowl, turning it once to coat. Cover the bowl with plastic wrap or a clean kitchen towel.
Let the dough rise in a warm place for 1 to 1.5 hours, or until doubled in size. Alternatively, for a deeper flavor, you can refrigerate the dough overnight (8-12 hours) for a slow cold proof.

2. Make the Filling

While the dough is rising, prepare your glorious filling. In a medium bowl, combine the softened unsalted butter, light or dark brown sugar, and ground cinnamon. Mix everything together with a fork or spatula until it forms a thick, spreadable paste. Set aside.

3. Assemble the Rolls

Once the dough has doubled (or after cold proofing, bring it to room temperature for about 30 minutes), gently punch it down to release the air.
On a lightly floured surface, roll the dough into a large rectangle, approximately 12×18 inches (30×45 cm) and about 1/4 inch (6 mm) thick.

Evenly spread the cinnamon-sugar filling over the entire surface of the dough, leaving a small 1/2-inch border on one of the longer edges.
Starting from the longer edge opposite the border, tightly roll the dough into a log. Pinch the seam gently to seal it.
Using a sharp knife, unflavored dental floss, or a serrated knife, cut the log into 12 equal rolls, each about 1.5 inches (4 cm) thick.

Arrange the rolls in a lightly greased 9×13 inch (23×33 cm) baking dish, leaving a little space between each roll as they will expand.

4. Second Rise and Bake

Cover the baking dish loosely with plastic wrap or a clean kitchen towel. Let the rolls rise in a warm place for another 30-45 minutes, or until they look puffy and have nearly doubled in size.
Preheat your oven to 375°F (190°C) about 15 minutes before the end of the second rise.

Bake the cinnamon rolls for 20-25 minutes, or until they are golden brown on top and cooked through. If they start browning too quickly, you can loosely tent them with foil.
Remove from the oven and let them cool in the pan for 5-10 minutes while you make the frosting.

5. Prepare the Cream Cheese Frosting

In a medium bowl, with an electric mixer, beat together the softened cream cheese and softened unsalted butter until smooth and creamy.

Gradually add the powdered sugar, one cup at a time, beating until fully incorporated.
Stir in the vanilla extract. Beat until the frosting is light, fluffy, and smooth. If it’s too thick, you can add a tablespoon of milk or cream until desired consistency is reached.

6. Frost and Serve

Spread the cream cheese frosting generously over the warm (or slightly cooled) cinnamon rolls. Serve immediately and enjoy!

Tips & Suggestions

Here are a few of my favorite tips to ensure your Sourdough Discard Cinnamon Rolls turn out perfectly every time:

Don’t Over-Flour: When kneading or rolling out the dough, resist the urge to add too much extra flour. A slightly sticky dough makes for a softer, more tender roll. Use just enough flour to prevent sticking.
Overnight Proofing for Convenience: If you want fresh cinnamon rolls for breakfast without the early start, proof the assembled (unbaked) rolls in the refrigerator overnight. Just pull them out in the morning and let them come to room temperature for 30-60 minutes before baking.

The Dental Floss Trick: For perfectly clean-cut cinnamon rolls, slide a piece of unflavored dental floss underneath your rolled dough log. Cross the ends of the floss over the top, pull them tight, and watch it slice through the dough effortlessly.
Warm vs. Cooled Frosting: I love frosting my rolls while they’re still warm – it creates a melty, gooey layer that’s absolutely divine. If you prefer a more defined, thicker frosting, wait until the rolls have cooled completely.
Vary Your Filling: Feel free to experiment with the filling! Add a pinch of nutmeg or cardamom for an extra layer of spice, or finely chopped pecans or walnuts for some crunch.

Achieving a Golden Brown: Keep an eye on your rolls while baking. Ovens vary, and you want that perfect golden hue without overbaking, which can dry them out.

Storage

You’ll probably devour most of these quickly, but in case you have leftovers, here’s how to keep your Sourdough Discard Cinnamon Rolls fresh:

Room Temperature: Unfrosted cinnamon rolls can be stored in an airtight container at room temperature for up to 2 days. Once frosted, due to the cream cheese, they are best kept refrigerated.

Refrigeration: Frosted cinnamon rolls should be stored in an airtight container in the refrigerator for up to 5 days. You can gently warm them in the microwave for 15-20 seconds before serving to bring back their softness.
Freezing Baked Rolls:
- With Frosting: Place cooled, frosted rolls on a baking sheet and freeze until the frosting is firm (about 1-2 hours). Then, wrap each roll individually in plastic wrap, followed by aluminum foil. Store in a freezer-safe bag or container for up to 1 month. Thaw at room temperature or warm gently in the microwave or oven.
- Without Frosting: Allow baked rolls to cool completely. Wrap each roll individually in plastic wrap and then foil. Place them in a freezer-safe bag or container for up to 3 months. To reheat, unwrap and warm in a preheated oven at 300°F (150°C) for 10-15 minutes, or microwave for 30-60 seconds. Frost after reheating.
Freezing Unbaked Rolls: You can prepare the rolls and arrange them in your baking dish. Cover tightly with plastic wrap and then foil, then freeze for up to 2-3 weeks. When ready to bake, transfer them to the refrigerator overnight to thaw and rise slowly, or let them sit at room temperature for 3-4 hours until puffy before baking as directed.

Final Thoughts

And there you have it! What a journey, from a simple cup of sourdough discard to a pan of pure bliss. I truly believe these Sourdough Discard Cinnamon Rolls are a must-try for anyone who loves a good homemade treat. They represent the perfect marriage of practicality and indulgence, transforming what might otherwise be waste into something utterly spectacular.

The subtle tang from the sourdough discard isn’t just a gimmick; it genuinely elevates the flavor, cutting through the sweetness of the filling and the rich cream cheese frosting to create a beautifully balanced bite. Plus, the dough often comes out incredibly soft and tender, thanks in part to that unique addition. You’ll find yourself wondering why you ever made cinnamon rolls any other way!
