This caramel popcorn is plain popcorn tossed in a quick stovetop glaze of brown sugar, butter, corn syrup and a pinch of baking soda, then baked low at 250°F for 45 minutes. It makes about 12 cups, takes just under an hour, and comes out crunchy, not chewy or sticky. You do not need a candy thermometer.
The oven does the real work. The low heat dries the glaze onto every piece, and stirring every 15 minutes keeps the coating even.

- Popcorn: 12 cups freshly popped, plain and unsalted (about 1/2 cup kernels)
- Glaze: 1 cup packed brown sugar, 1/2 cup (1 stick) unsalted butter, 1/4 cup light corn syrup, 1/2 teaspoon salt
- Stirred in at the end: 1/2 teaspoon baking soda, 1 teaspoon vanilla
- Oven: 250°F (120°C), 45 minutes, stirred every 15
- Time: 10 minutes hands-on, about 55 minutes in total
That ratio is the whole recipe: 1 cup brown sugar, 1/2 cup butter and 1/4 cup corn syrup coat 12 cups of popcorn in a thin, even shell.
Popping 12 Cups of Plain Popcorn
Air-popped, stovetop with 1 tablespoon of neutral oil, or plain microwave bags all work. I have made it all three ways. What matters is that the popcorn is fresh and has no butter or salt on it, because buttered popcorn turns greasy under the glaze.
Tip it into your biggest bowl and pick out the unpopped kernels now. Once they are glazed you cannot see them, and nobody wants to bite one.
Cooking the Brown Sugar Glaze
Turn the oven on to 250°F before you start, so the coated popcorn can go straight in. In a medium saucepan over medium heat, stir the brown sugar, butter, corn syrup and salt until it comes to a gentle boil.
Then stop stirring and let it simmer undisturbed for 4 to 5 minutes. Stirring a boiling sugar syrup drags sugar crystals from the sides back into it, and the glaze turns grainy. The corn syrup helps here too. I have tried honey in its place. It left the popcorn slightly chewy, while corn syrup gave the lightest, most even crunch.
Why the Baking Soda Foams
Take the pan off the heat and stir in the baking soda and vanilla. The glaze foams up and turns paler. Those tiny bubbles are what make the finished coating light and brittle instead of a hard candy shell that sticks to your teeth. The foam settles within a minute or so, so have the popcorn ready and pour right away. If your baking soda is old and barely foams, replace it.
Coating and Baking Low at 250°F
Pour the foaming glaze over the popcorn and fold it with a heatproof spatula until every piece is streaked. Spread it on a parchment-lined rimmed baking sheet in a single layer. If it piles up, use two sheets.
Bake for 45 minutes and stir every 15 minutes, moving the edges to the middle. The glaze darkens slightly and dries to a gloss. It only finishes crisping as it cools, so leave it on the sheet until completely cool, then break it into clusters.
Caramel Sauce or Baked Glaze on Popcorn?
A lot of people search for caramel sauce to drizzle on popcorn. You can pour warm homemade caramel sauce over a bowl for a soft, sticky treat, but the cream in it never dries, so the popcorn goes soft within hours. Eat that version the same day. This butter and brown sugar glaze has no cream, and baking dries it into a crunchy coating that keeps for a week. For a gift bag, a party bowl or anything made ahead, use the glaze.
Chewy, Sticky or Scorched?
- Still chewy: pull out a piece and let it cool for a minute. If it bends instead of snapping, bake 10 to 15 minutes more.
- Sticky the next day: it was underbaked or the container let in air. Spread it out and recrisp at 250°F for about 10 minutes.
- Grainy glaze: it was stirred after it boiled. Next time, hands off for the full 4 to 5 minutes.
- Dark, bitter edges: the popcorn was piled up or not stirred. Keep it in one layer and stir every 15 minutes.
- Thin, patchy coating: the foam had collapsed before you poured. Have the bowl ready before the soda goes in.
Add Ins, Gift Bags and Party Bowls
Toss in 1 cup of salted peanuts or pecans with the popcorn before you pour, sprinkle flaky sea salt on the hot popcorn as it comes out of the oven, or drizzle melted chocolate over the cooled clusters. For a heavier, more candy-like coat, double the glaze and expect to bake a little longer.
For fall gatherings I pack it in brown paper cones or glass jars tied with string. Ten minutes of bagging and it is done. It sits well on a Halloween snack table, and in December there is my Christmas popcorn. Next to homemade caramel apples and a plate of salted caramels it makes a full caramel table.
Keeping It Crunchy for a Week
Once completely cool, store the caramel popcorn in an airtight container at room temperature for up to a week. Humidity is what softens it, so close the lid tight and keep it away from the stove and the dishwasher. In my house it rarely lasts past day three.
Caramel Corn Questions
Can I make caramel popcorn without corn syrup?
Honey works, but the coating comes out slightly chewy instead of crisp. Corn syrup keeps the glaze smooth and the crunch light.
Is this like Amish caramel corn?
It is close. Amish-style caramel corn is also a brown sugar and butter glaze baked low in the oven, the kind you find at markets and fairs.
Can I skip the oven?
You can eat it straight from the bowl, but it stays soft and sticky. The 45 minutes at 250°F is what makes it crunchy and lets it keep.

Caramel Popcorn Recipe
This caramel popcorn is a crunchy homemade caramel corn made with freshly popped popcorn and a stovetop glaze of brown sugar, butter, light corn syrup, salt, baking soda and vanilla. One batch makes about 12 cups in just under an hour, baked at 250°F for 45 minutes and stirred every 15 minutes until the coating is dry, glossy and crisp. The baking soda makes the caramel glaze foam, which gives a light, brittle coating instead of a sticky one, so no candy thermometer is needed. Pack it in gift bags, set it out for Halloween and movie nights, or serve it at fall parties. Toss in peanuts or pecans or add flaky salt. It keeps for up to a week in an airtight container at room temperature.
Ingredients
- FOR THE POPCORN
- 12 cups freshly popped popcorn (about ½ cup kernels or use plain air-popped)
- 1 tablespoon neutral oil (if popping on the stove)
- FOR THE CARAMEL GLAZE
- 1 cup packed brown sugar
- ½ cup unsalted butter (1 stick)
- ¼ cup light corn syrup
- ½ teaspoon salt
- ½ teaspoon baking soda
- 1 teaspoon pure vanilla extract
Instructions
- PREPARE THE POPCORN: Pop the kernels using your preferred method—stovetop, air popper, or plain microwave. Transfer the popcorn to a large mixing bowl and carefully remove any unpopped kernels to avoid biting into hard pieces later.
- MAKE THE CARAMEL GLAZE: In a medium saucepan over medium heat, combine brown sugar, unsalted butter, corn syrup, and salt. Stir continuously until the mixture comes to a gentle boil, then stop stirring and let it simmer undisturbed for 4 to 5 minutes.
- FINISH THE GLAZE: Remove the saucepan from heat and stir in the baking soda and vanilla extract. The mixture will foam and expand—this is expected and helps aerate the caramel for a lighter coating.
- COAT THE POPCORN: Immediately pour the hot caramel mixture over the prepared popcorn. Use a heatproof spatula or wooden spoon to gently toss and evenly coat the popcorn with the glaze.
- BAKE FOR CRISPINESS: Preheat the oven to 250°F (120°C). Spread the coated popcorn evenly on a parchment-lined baking sheet. Bake for 45 minutes, stirring every 15 minutes to redistribute the caramel and ensure even crisping.
- COOL AND STORE: Remove the baking sheet from the oven and allow the popcorn to cool completely. Once cooled, break into clusters and transfer to an airtight container to maintain freshness.
Notes
Use plain, unsalted, unbuttered popcorn and remove unpopped kernels before coating. Preheat the oven to 250°F before you start the glaze so the coated popcorn goes straight in. Stop stirring once the glaze boils, or it can turn grainy. Pour the glaze while the baking soda is still foaming; the bubbles make the coating light and crunchy. Spread the popcorn in a single layer and stir every 15 minutes so it bakes evenly without scorching. If a cooled piece is still chewy, bake 10 to 15 minutes longer. Store in an airtight container at room temperature for up to one week; recrisp sticky popcorn at 250°F for about 10 minutes.
This Caramel Popcorn is absolutely amazing! I love it and so does my husband. I made a double batch yesterday and it’s still crunchy today. I have made Caramel popcorn before and baking it afterwards is key to keeping it crunchy. Thanks so much.
That’s so great to hear, Coleen! You’re absolutely right baking really makes the difference for that lasting crunch. So glad you and your husband are enjoying it!
