Sourdough Discard Cinnamon Rolls

These Sourdough Discard Cinnamon Rolls are a great way to use up some of your sourdough discard and make a delicious treat for breakfast, brunch, or a sweet afternoon treat! I added raisins to the filling, but you could easily change that for something else (check out some of my favorite variations below)!

I've also included directions below on how to make overnight cinnamon rolls, in case you want to prep them the day before baking!

Ingredients

There are only a few ingredients you'll need to make these Sourdough Discard Cinnamon Rolls.

• Non-dairy milk: I like to use unflavored almond milk, but this would work with any non-dairy or regular dairy milk. Heat the milk in the microwave until warm but not boiling, about 30 seconds.
• Active yeast: Even though we're using sourdough discard, we need to use a leavening agent (in this case, yeast) to make sure the dough rises predictably.
• Egg: You will want the egg to be room temperature before adding to the recipe.
• Sourdough discard: The sourdough discard should be unfed and at room temperature for this recipe. This recipe is designed to be made from a sourdough starter that uses a 1:1 ratio (when you feed your starter, it's with 1 part flour and 1 part water). If your starter uses a different ratio, you may need to adjust some of the ingredients in this recipe.
• Brown sugar: Brown sugar combines with the butter, cinnamon, and raisins to create the filling between the layers of the rolls.
• Raisins: These are optional and you can certainly leave them out (I know there are some strong opinions about raisins!), but I think they add a nice pop to the recipe. See the variations section below for a few other add-in ideas.
• Unsalted butter: There is a good bit of butter in this recipe, and you want almost all of it to be softened at room temperature. Don't forget to take that butter out of the fridge!

See full recipe below for detailed directions.

Substitutions & Variations

This is a very adaptable recipe and below are a few easy substitutions and variations you can try.

• Use active sourdough starter: If you'd like to make this recipe with active sourdough starter instead of discard, you can! To do so, omit the yeast and replace the sourdough discard with sourdough starter. You will also need to adjust the rise times.
• Use regular dairy milk: This recipe uses non-dairy milk, but this recipe will also work just as well with regular dairy milk.
• Use rum- or bourbon-soaked raisins: While your dough is rising, soak the raisins in rum or bourbon. This will help them plump up, but also add some of that spirit flavoring!
• Add crushed nuts: Add ¼ cup crushed almonds, pecans or walnuts when you're spreading the cinnamon sugar mixture.

How to Make Sourdough Discard Cinnamon Rolls

Letting the dough rise for enough time is the key to success with this recipe. There are a few easy steps you'll need to follow to make these Sourdough Discard Cinnamon Rolls!

Mix the dough ingredients, then place in a large, greased bowl and let rise for 60-90 minutes until doubled in size.

Roll the dough into a roughly 12x18-inch rectangle on a floured surface.

Spread the dough with the softened butter, then sprinkle with cinnamon, brown sugar and drained raisins. Be generous with the filling!

From the long end of the rectangle, roll the dough into a log. It shouldn't be loose, but doesn't need to be super tight, either!

Using unflavored dental floss or a sharp knife, cut the rolled log into 12 approximately equal-sized pieces.

Place the pieces cut-side up in a greased 9x13-inch baking dish. They will not fill the pan fully, but they will expand with the second rise. Cover with a towel and let rise for 45 minutes.

After the second rise, the rolls should be touching each other in the pan. Bake for 30-35 minutes until golden brown. Set aside to let cool.

While the rolls are cooling, combine the ingredients to make the frosting.

Once the rolls have cooled, spread with the icing.

Serve and enjoy!

How to Cut Cinnamon Rolls

Cutting the rolls is an important step. You want to make sure the rolls are equal in thickness so they will cook evenly. If they're a little bit off (especially those end pieces), that's ok, but you want to get them as close as possible to the same thickness.

There are a few ways to cut cinnamon rolls:

• Use dental floss: This is my preferred method. Use an unflavored dental floss (if it's flavored, you'll taste that in the final rolls!) and wrap it around the log. Cross the ends over the log and pull to pinch-cut the rolls. Dental floss is ideal here as it's very thin and strong and will cut through the dough easily. I do not recommend using kitchen twine, or a thicker string to try to do this, as that will tear the rolls rather than cutting them cleanly.
• Use a sharp knife: You can also use a large, sharp knife to cut the rolls. Again, you want them to be equal in thickness, and try to get a crisp cut rather than a tear. I like to use an 8-inch chef's knife so you can make one clean cut (rather than needing to make a sawing motion with a smaller knife or a serrated knife).
• Cut the dough before rolling the rolls: After you spread the filling on the dough, you can use a pizza cutter to cut dough strips. You will then roll each strip into a cinnamon roll. For this, you are cutting before rolling (unlike the above methods). This works well, but I find you need to be a bit more precise with measurements and cutting to size!

For this recipe, I recommend cutting the log into 12 rolls. But cinnamon rolls are very versatile and you could easily cut into fewer or more rolls to fit your baking pan!

What is Sourdough Discard?

Sourdough discard is what you have left over after you feed a sourdough starter. You can either literally discard it (compost, or throw it away), or you can use it in sourdough discard recipes like this one.

This recipe is designed for a sourdough starter with a 1:1 ratio (when you feed your starter, it's with 1 part flour and 1 part water). If your starter uses a different ratio, you may need to adjust some of the ingredients in this recipe.

Every sourdough starter is different. As you're kneading the dough, if it seems too dry (dense) or too wet (sticky), add more flour or milk (1 Tablespoon at a time) to reach your desired consistency.

Why does this recipe use yeast?

Sourdough discard is inactive, and needs a leavening agent (in this case, yeast) to help the dough rise predictably. You'll still get the benefit of the sourdough flavor, as well as some additional lift from the discard to make these cinnamon rolls extra fluffy. And the best part: you'll be putting your sourdough discard to good use!

Storage

Room Temperature Storage: Store the rolls covered or in an airtight container at room temperature for 2-3 days. They will harden as they dry out. You can reheat the rolls for 15-30 seconds in the microwave to make them warm and soft again.

Freezer Storage: These cinnamon rolls freeze very well. Once the cinnamon rolls are fully cooled, transfer to an airtight container or bag (I like to split them into individual rolls and store each in a plastic bag, which makes it easier to heat up just one roll at a time). Freeze for up to 3 months. To reheat, warm the cinnamon rolls in the microwave for about 60 seconds until soft and warm again.
