The aroma of warm, pillowy sourdough discard cinnamon rolls filling my kitchen on a lazy weekend morning is one of my favorite things in the world. It’s that perfect blend of sweet, spicy, and tangy, creating a treat so comforting it feels like a warm hug in every bite. And let me tell you, these blueberry cinnamon rolls are a truly special version.

I remember waking up to the smell of my grandmother’s kitchen on Sunday mornings, where she’d always have something baking. That nostalgic feeling, that sense of home and warmth, is what I strive to recreate with every recipe I share, especially with these rolls.

This recipe is fantastic for using up that often-overlooked sourdough discard, turning what could be waste into pure culinary gold. It’s surprisingly low stress, making it perfect for a cozy morning with the family. My top tip is always to prep the dough the night before for an even easier morning.

What You Need to Make This Recipe

My secret to these soft, delightful sourdough discard cinnamon rolls lies in a few simple yet powerful ingredients like the active sourdough discard for that signature tang, rich unsalted butter for flavor, and a hint of cinnamon for warmth, much like my favorite blueberry sourdough scones. You’ll find the full list of ingredients and precise measurements in the recipe card below.

How to Make Sourdough Discard Cinnamon Rolls

Making these incredible sourdough discard cinnamon rolls involves a few straightforward steps: first, preparing the wonderfully soft dough using your active sourdough discard. Then, you’ll assemble those glorious rolls with a generous cinnamon-sugar filling. After a quick rise, they’re baked to golden perfection, just like I do with my sourdough discard biscuits. Finally, we’ll whip up a creamy, dreamy cream cheese frosting to top them off.

Pro Tips for Making This Sourdough Discard Cinnamon Rolls

Creating the perfect batch of sourdough discard cinnamon rolls is a truly rewarding experience, and I’ve learned a few tricks over the years that I’m excited to share with you.

Mastering the Dough

Don’t rush the dough’s first rise. The sourdough discard needs time to work its magic, giving you that incredible fluffy texture. I always look for the dough to at least double in size, which might take a bit longer in a cooler kitchen.

Achieving the Perfect Filling

Be generous with your cinnamon-sugar mixture! It might seem like a lot, but that’s what creates those irresistible swirls of flavor. Make sure the softened butter is evenly spread before sprinkling the sugar and cinnamon for maximum coverage.

My Secret Trick: My secret for truly soft, airy sourdough discard cinnamon rolls is to use whole milk in the dough and make sure all your cold ingredients, especially the egg and milk, are at room temperature. This helps everything incorporate smoothly and promotes a more active yeast, leading to a much fluffier final product.

How to Store Sourdough Discard Cinnamon Rolls

To keep your delicious sourdough discard cinnamon rolls fresh, I recommend storing any leftovers in an airtight container at room temperature for up to two days. If you want them to last longer, pop them in the fridge for up to a week. For reheating, my personal tip is to warm them gently in the microwave for 15-20 seconds or in a low oven (around 250°F) until soft and warm. This brings back their wonderful fresh-baked texture and makes them taste just as good as the first bite!

Nutritional Benefits

While these sourdough discard cinnamon rolls are certainly a treat, they do offer some benefits. The fermentation in sourdough can aid digestibility, and with ingredients like whole milk and eggs, they provide a comforting start to the day. It’s all about balance in my family-friendly kitchen!

FAQs

Can I make the sourdough discard cinnamon rolls dough ahead of time?

Absolutely! I often prepare the dough for these sourdough discard cinnamon rolls the night before. After the first rise, you can shape the rolls and place them in your baking dish, then cover and refrigerate overnight. Simply take them out about an hour before baking to come to room temperature and rise slightly before popping them in the oven.

What if I don’t have instant yeast?

If you only have active dry yeast, you can still make these fluffy sourdough discard cinnamon rolls. Just make sure to activate it first by dissolving it in a small amount of warm milk (from the recipe’s total) with a pinch of sugar for about 5-10 minutes until foamy. Then proceed with the recipe as usual.

Can I freeze the baked sourdough discard cinnamon rolls?

Yes, you can! I often bake a big batch of sourdough discard cinnamon rolls and freeze some. Once they’ve cooled completely, wrap them individually or in small batches and store them in an airtight freezer-safe bag for up to 2-3 months. Thaw and reheat for a quick, comforting breakfast.

How do I prevent my cinnamon rolls from drying out?

The key to moist sourdough discard cinnamon rolls is not to overbake them. They should be lightly golden brown on top. Another tip I swear by is to frost them while they are still warm, allowing that luscious cream cheese frosting to melt slightly into the rolls, keeping them wonderfully soft.

Ingredients
  

For the Dough
  • 1 cup sourdough discard (approx. 240g), unfed, at room temperature
  • 1 cup whole milk warm (about 105-115°F / 40-46°C)
  • 2 tsp instant yeast
  • 1/4 cup granulated sugar
  • 1 large egg at room temperature
  • 1/4 cup unsalted butter (57g), melted and cooled
  • 1 tsp fine sea salt
  • 3 1/2 - 4 cups all-purpose flour (420-480g), divided, plus more for dusting
For the Filling
  • 1/2 cup unsalted butter (113g), softened
  • 3/4 cup light brown sugar (150g), packed
  • 2 tbsp ground cinnamon
For the Cream Cheese Frosting
  • 4 oz cream cheese (113g), softened
  • 1/4 cup unsalted butter (57g), softened
  • 2 - 3 cups powdered sugar (240-360g), sifted
  • 1 tsp vanilla extract
  • 1 - 3 tbsp milk or heavy cream as needed for consistency

Equipment

  • Stand mixer with dough hook
  • Large Mixing Bowl
  • Measuring cups and spoons
  • Rolling Pin
  • 9x13-inch baking dish
  • Whisk
  • Rubber spatula
  • Electric Hand Mixer

Method
 

Prepare the Dough
  1. In the bowl of a stand mixer (or a large mixing bowl if kneading by hand), combine the warm milk, sourdough discard, instant yeast, and granulated sugar. Stir gently and let sit for 5-10 minutes until slightly foamy, indicating the yeast is active.
  2. Add the egg, melted and cooled butter, and salt to the wet ingredients. Mix well.
  3. Gradually add 3 cups of the all-purpose flour, mixing on low speed with the dough hook until just combined. Add the remaining flour 1/2 cup at a time until the dough comes together and pulls away from the sides of the bowl. It should be slightly sticky but manageable. (You may not need all 4 cups of flour).
  4. Increase speed to medium and knead for 8-10 minutes with the dough hook until the dough is smooth, elastic, and passes the windowpane test. If kneading by hand, knead on a lightly floured surface for 10-15 minutes.
  5. Lightly grease a large bowl. Transfer the dough to the bowl, turning once to coat. Cover the bowl with plastic wrap or a clean kitchen towel. Let rise in a warm place for 1 to 2 hours, or until doubled in size.
Assemble the Rolls
  1. While the dough is rising, prepare the filling. In a small bowl, combine the softened butter, brown sugar, and ground cinnamon. Mix until well combined and spreadable.
  2. Lightly flour a clean work surface. Turn the risen dough out onto the surface and gently punch it down. Roll the dough into a large rectangle, approximately 12x18 inches (30x45 cm).
  3. Evenly spread the cinnamon filling over the entire surface of the dough, leaving a small 1/2 inch border along one of the longer edges.
  4. Starting from the long edge opposite the border, tightly roll the dough into a log. Pinch the seam closed to seal. Use a sharp knife or unflavored dental floss to cut the log into 12 even slices (about 1.5 inches thick each).
  5. Lightly grease a 9x13 inch baking dish. Arrange the cut cinnamon rolls in the prepared dish, leaving a little space between each as they will expand. Cover the dish with plastic wrap or a clean kitchen towel and let rise in a warm place for another 45-90 minutes, or until puffy and almost doubled in size.
Bake the Rolls
  1. Preheat your oven to 375°F (190°C) about 15 minutes before the second rise is complete.
  2. Bake the cinnamon rolls for 25-30 minutes, or until golden brown on top and cooked through. If they start browning too quickly, you can loosely tent them with foil.
  3. Remove from the oven and let cool slightly in the pan while you prepare the frosting.
Make the Cream Cheese Frosting
  1. In a medium bowl, beat together the softened cream cheese and softened butter with an electric mixer until smooth and creamy.
  2. Gradually add the sifted powdered sugar, 1 cup at a time, beating until fully incorporated. Add the vanilla extract and 1 tablespoon of milk or cream. Beat until smooth.
  3. Add additional milk or cream, 1 teaspoon at a time, until the frosting reaches your desired smooth, spreadable consistency.
Serve
  1. Spread the cream cheese frosting generously over the warm (but not hot) cinnamon rolls. Serve immediately and enjoy!

Notes

For the best flavor and texture, these sourdough discard cinnamon rolls are best enjoyed the day they are baked. Store any leftovers in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. Reheat gently in the microwave or oven. For make-ahead, you can assemble the rolls and do the second proof in the fridge overnight. In the morning, take them out 1-2 hours before baking to come to room temperature and finish rising, then bake as directed.

Conclusion

I truly hope you’ll try making these soft and fluffy sourdough discard cinnamon rolls! They are a testament to how simple ingredients, combined with a little love and patience, can create something truly extraordinary. There’s nothing quite like sharing a warm, homemade treat with loved ones, just like I love to make my potato spinach frittata for brunch. It’s comforting, practical, and a delicious way to bring that homemade warmth to your family’s table.
