Let Me Tell You About These Sourdough Discard Cinnamon Rolls

Okay, so you know that feeling when you open the fridge and see yet another jar of sourdough discard staring at you with judgement? That’s pretty much how this recipe started for me. I was on a baking rampage (as one does after a rainy weekend with nowhere to be) and ended up with more discard than sense. One afternoon, I thought: why not cinnamon rolls? Turns out, they soak up that tangy flavor like a sponge, and the results—well, my partner calls them “dangerously good.” Seriously, one time my neighbor stopped by for a quick hello, left with three rolls, and texted me for the recipe before she even got home. If only my attempts at sourdough bread itself were always this successful. (But that’s a story for another time. Remind me to tell you about my infamous brick loaf…)

Why I Keep Coming Back to This Recipe

I make these when I’ve got that nagging bit of discard and want something a bit fancy but that still feels like cheating. My family goes absolutely bonkers for them because they’re soft, gooey, a little tangy, and not too sweet (though you can totally up the sugar if that’s your jam). Also, these rolls are very forgiving; I’ve thrown this dough together late at night and finished it in the morning, and no one ever noticed. Oh, and that vanilla glaze? I could eat it with a spoon. Actually, I did once—no regrets. If rolling dough makes you nervous, trust me, it gets less intimidating. Just don’t stress about making perfect spirals; the messy ones are always my favorite anyway.

What You’ll Need to Make These Cinnamon Rolls

For the Dough:

1 cup (about 240g) sourdough discard (unfed, straight from the fridge is fine; I’ve used bubbly discard too, just use what you have)
1/2 cup milk (dairy or honestly, oat milk works in a pinch – I’ve also tried almond milk, but the flavor was a bit odd for me)
1/4 cup sugar (granulated, but brown is good for extra depth)
1 large egg
1/4 cup melted butter (sometimes I do half butter, half coconut oil, especially if I ran out – which happens a lot)
2 1/2 cups all-purpose flour (my grandma swore by King Arthur, but store-brand is totally fine)
1 tsp salt
2 tsp instant or active dry yeast (not technically necessary with active starter, but I like the extra oomph for a fluffier roll)

For the Filling:

1/2 cup brown sugar (or coconut sugar if you’re feeling adventurous)
2 tbsp ground cinnamon (I eyeball this, honestly)
4 tbsp softened butter (I just nuke it for a few seconds if I forget to soften it—no shame)
Pinch of salt (I like flaky salt, but table salt is fine)

For the Vanilla Glaze:

1 cup powdered sugar (sift it if you want, but I rarely do)
2 tbsp milk (any milk, really)
1 tsp vanilla extract (I like the real stuff, but the imitation kind works too in a pinch)
Optional: a squeeze of lemon juice for a bit of zing

How I Actually Make These Rolls (Step by Step-ish)

Warm Up the Milk: Pop the milk in the microwave just until it’s warm—not hot (think bathwater, not soup). If you scald it, just let it cool a bit, no biggie.
Mix Up the Dough: In a big bowl, whisk together the sourdough discard, warm milk, sugar, egg, and melted butter. Sprinkle in the yeast; let it sit for a couple minutes while you measure the flour (I use this time to scroll through my phone, honestly). Add flour and salt. Stir with a wooden spoon until it’s a shaggy mess.
Knead: Dump it onto a floured counter and knead for about 5-7 minutes. Or do it in your stand mixer with the dough hook if you’re feeling fancy. The dough should be smooth but still a little tacky. Don’t overthink this. It always looks weird at this stage—totally normal.
First Rise: Toss the dough in a lightly greased bowl, cover with a tea towel or cling film (whatever’s handy), and let it rise until doubled. About an hour if your kitchen is warm; sometimes it takes longer. Go walk the dog or watch an episode of Bake Off.
Roll & Fill: Tip the dough out onto a floured surface. Roll it into a rough rectangle—mine’s never perfectly rectangular, and it doesn’t matter. Smear the softened butter over the dough. Mix the brown sugar and cinnamon (plus salt), sprinkle it all over. Pat it down so it sticks.
Roll It Up: Roll the dough up tightly from the long edge (or the short edge if you like thicker rolls). Pinch the seam shut. Slice into 8-12 rolls, depending how big you want ’em. (Tip: I use dental floss for clean cuts. Regular thread works too, or just a sharp knife.)
Second Rise: Arrange the rolls in a greased baking dish. Cover, let them puff up for 30-45 minutes. They’ll look a bit wonky—that’s fine.
Bake: Bake at 350°F (180°C) for 22-28 minutes, until golden. I usually check at 22 minutes. If you like crispier edges, go a bit longer. This is where I always get impatient and poke them with my finger.
Make the Glaze: While the rolls are cooling slightly, whisk up the powdered sugar, milk, vanilla (and lemon juice, if using). Pour, drizzle, or slather over warm rolls. I go heavy on the glaze, but that’s just me.

Stuff I Learned (Usually the Hard Way)

If your dough feels too sticky to handle, just add a bit more flour. I used to panic—then I realized a dusting solves it.
Letting the dough rise overnight in the fridge totally works. The flavor is deeper (but don’t forget to let it come to room temp before rolling, or you’ll be fighting cold dough. Been there.)
If you forget to grease the pan, the rolls stick but come out eventually (with enough patience and a spatula).

Variations I’ve Tried (the Good and the Not-So-Good)

Swap the cinnamon for pumpkin pie spice in autumn—instant cozy vibes.
Add some chopped pecans or walnuts in the filling. I did raisins once (controversial, I know); my kids staged a minor rebellion.
Maple glaze instead of vanilla—delicious, but a little too sweet for my taste.
Once I tried stuffing the rolls with cream cheese before baking. It oozed everywhere. Tasted good, but the mess… oh boy.

What If I Don’t Have All the Right Equipment?

Honestly, you don’t need much. A rolling pin is helpful, but I’ve used a wine bottle in a pinch—works just fine. No stand mixer? Good old elbow grease will do. If you don’t own a baking dish, a rimmed baking sheet lined with parchment does the trick. Oh, and for cutting the rolls: if you don’t have floss or thread, a sharp knife run under hot water works, too. I once used fishing line, but that’s not something I’d recommend unless you’re desperate.

How Long Do These Last? (Not Long, Honestly)

Keep the cooled rolls in an airtight container at room temp for 1-2 days. You can pop them in the fridge, but they dry out a bit (though 10 seconds in the microwave sorts that out). Freeze for later if you must—but in my house, leftovers are basically mythical. Once my brother-in-law ate half the tray before dinner. True story.

How I Serve Them (and Sometimes Sneak One Early)

Warm, with coffee. Or tea. Or, if it’s the weekend, with a drizzle of extra glaze and a side of fresh berries. My kids like dunking them in milk (I think it’s weird, but hey, to each their own). If we’re having brunch guests, I pile them up on a big plate and set out extra glaze. No need for forks—fingers are fair game here. And if you want to get really wild, top with a scoop of vanilla ice cream while they’re still warm. Just saying.

My Hard-Earned Pro Tips

Don’t rush the rising. I once tried to shortcut a rise by setting the bowl on top of a radiator. It kind of… cooked the bottom. Not my finest hour.
If your glaze looks lumpy, just keep whisking. Or accept a few lumps. It’ll still taste good.
Don’t slice the rolls too thin or they dry out. Bigger is always better here, in my opinion.

Questions People Actually Ask Me

Can I make these ahead? Yep! I usually assemble and do the second rise in the fridge overnight. Just let them sit out for 30 mins or so before baking.
Can I use fed starter instead of discard? Sure, but tbh, the discard is nicer for not wasting. The flavor’s a little tangier with fed starter, though.
Can I skip the yeast? You can, especially if your starter is super active, but the texture gets a bit dense. On second thought, I like the boost from a little yeast.
Do these freeze well? They do, but I think they’re best fresh. If you freeze, just reheat gently so they don’t go tough.
Is there a gluten-free version? I haven’t nailed one yet. I tried swapping in a 1:1 gluten free flour, but the dough was weirdly gritty. If you figure it out, let me know!
What else can I do with sourdough discard? Oh, so many things! Pancakes, crackers, even brownies. I’m obsessed with The Perfect Loaf—Maurizio has loads of ideas. Or check out this King Arthur Flour discard recipe collection for more inspiration.

And that’s the gist. If you give these Sourdough Discard Cinnamon Rolls with Vanilla Glaze a try, let me know how they turn out—or if you invent some wild new filling. Never hurts to experiment, as long as you don’t mind a bit of flour on your shirt (or the dog, as sometimes happens here…)
