If you're craving the cozy aroma of warm baked cinnamon rolls but have no time for all that kneading or rising, whip up this cinnamon bun popcorn instead. It packs all those bakery vibes into your kitchen in less than an hour. Love your popcorn with a little twist? This popcorn is made for snacking on the couch, binge-watching your favorites, or lazy chill sessions on the weekend.

Irresistible Ingredients

  • Plain popped popcorn: This is what everything builds on—go for unsalted or air-popped if you can. Leave out bagged flavored corn for best crunch.
  • Mini marshmallows: This brings a chewy softness to the mix. Look for the fluffiest, freshest bag so they melt right.
  • Vanilla extract: All the bakery flavors show up with real vanilla, if you have it.
  • Baking soda: This makes the sweet coating airy and lighter, giving a crisp snap. Fresh box works best.
  • Ground cinnamon: The main flavor—find a jar that smells super fragrant for that punchy cinnamon bun feel.
  • Kosher salt: This keeps the whole thing from being way too sweet, plus adds a little pop of flavor. Use coarse or fine, whatever's handy.
  • Light corn syrup: The glue that holds the sweet syrup together, so everything sticks. Clear and not old works best.
  • Granulated sugar: Balances out the brown sugar and keeps things light.
  • Brown sugar: Rich caramel notes that really make the flavor, dark or light is up to you.
  • Butter: All the flavor sticks thanks to this—choose salted for a boost in taste.

Simple Step-by-Step

Cool and Enjoy:
Pull the popcorn from the oven, mix one last time, and let it sit out until totally cool. Go ahead and munch right away, or stash in a tight container for later.
Bake and Stir:
Put the sheet in to bake. Stir after 15 minutes, do it again 15 minutes later. Give it an extra 5 to 10 minutes in the oven for some crispness, then pull out.
Coat the Popcorn:
Spread your popcorn on the lined baking pan. Pour the hot syrup over top, and use a spatula or big spoon to gently toss. Be careful not to smash the kernels.
Add Flavorings:
Remove the pot right away from the heat and dump in the vanilla, marshmallows, cinnamon, and baking soda. It'll foam up—totally fine! Stir until everything melts together and it's smooth.
Cook the Syrup:
When it bubbles, leave it alone (don’t stir, or the sugar might get grainy). Set a timer for 5 minutes. Lower the heat a bit if you have a gas range, just so the sugar doesn't burn.
Make the Cinnamon Coating:
In a heavy pot, melt butter over medium heat until bubbly. Don’t let it brown. Pour in the sugars, corn syrup, and salt. Stir it up until shiny and blended, then let it hit a low boil.
Preheat and Prep:
Flip on your oven to 225 F. Cover a rimmed baking tray with a silicone mat—makes cleanup a breeze and nothing will stick.

My absolute favorite part? The cinnamon gets into every nook and cranny of the popcorn. Nothing beats that sweet, spicy aroma in my kitchen—totally takes me back to childhood mornings baking with my family around the holidays.

Best Ways to Store

To keep this popcorn crisp, store it in a zipped bag or a tin with a good lid, right on the counter. Don't put it in the fridge—the cold just makes it tough. Sealed up, it'll stay tasty for about a week, although ours always disappears before then!

Different Options

Swap butter for vegan sticks or coconut oil for plant lovers. No corn syrup? Honey or golden syrup will do the trick. Only have big marshmallows? Snip 'em smaller and toss right in.

Fun Serving Ideas

Scoop into big bowls for family movie time, or tie up in bags for a sweet gift during the holidays. It's also awesome at kids' parties or showers. Use cupcake liners for grab-and-go snacks.

Frequently Asked Questions

→ What's the trick to keeping popcorn crunchy?

Keep the heat low while baking and mix it up a few times. That way, any extra dampness cooks off and you get that perfect crispy shell.

→ Can I grab microwave popcorn for this?

Sure, just pick one that's plain and doesn't have any extra flavor or salt. Coating sticks better this way.

→ Is there an easy swap for corn syrup?

Try using honey or golden syrup if that's what you've got. The texture might shift a bit, but it'll still work. Corn syrup keeps it all shiny and smooth.

→ How do I keep it fresh?

When it's cool, just toss it in a tight container and leave it out on the counter. It'll stay crunchy for about a week.

→ Can I toss in nuts or chocolate?

Go ahead! After you've baked it, mix in nuts like pecans or walnuts or sprinkle in some white chocolate for a fun bite.

Yield: 15 Servings (1 large batch)

Dietary: Gluten-Free

Ingredients

→ Main Mixture

01 1 cup mini marshmallows
02 1 teaspoon vanilla extract
03 0.25 teaspoon baking soda
04 2 tablespoons ground cinnamon
05 0.5 teaspoon kosher salt
06 60 ml light corn syrup
07 100 g granulated sugar
08 100 g packed light brown sugar
09 115 g salted butter

→ Coating Base

10 9–10 cups plain popped popcorn

Instructions

Step 01

Let the popcorn cool off right on your baking tray. Wait until it’s nice and crunchy, then break it up into big chunks. Dig in once it’s totally set.

Step 02

Pop your tray back in the oven for 5 to 10 minutes if you want a bit more crunch. Stir it once more and take it out to finish.

Step 03

Stick the baking tray in your oven. Give it 15 minutes, then stir the popcorn around to get even coating.

Step 04

Spread all your popcorn on the lined baking pan. Pour your hot cinnamon syrup all over and toss it gently until every piece is covered.

Step 05

Take the pot off the burner. Toss in the cinnamon, baking soda, vanilla, and the marshmallows right away. Stir till it’s all smooth and the marshmallows melt.

Step 06

Let it bubble while stirring often. When it starts boiling, stop stirring and let it cook on its own for about 5 minutes. If it’s getting dark too quickly, turn the heat down.

Step 07

Start by melting butter in a sturdy pot on medium. Dump in the brown sugar, white sugar, corn syrup, and salt. Mix them up until smooth.

Step 08

Fire up your oven to 110°C. Line a big baking tray with a silicone mat to keep things from sticking.

Notes

  1. You can grab dark or light brown sugar—they both work for the syrup.
  2. Try 9 cups popcorn for a heavy coat or 10 cups for something lighter.
  3. Can’t find kosher salt? Use regular table salt, but use just 0.25 teaspoon.
