This is my late grandmother’s recipe for homemade caramel corn. Brimming with buttery flavor, sweet crunch, and from-scratch caramel, each handful (you’ll want to eat it that way!!) is undeniably irresistible. You’ll make the 6-ingredient caramel sauce on the stove, and while a candy thermometer is helpful, you certainly can get by without one. The recipe below is for plain caramel popcorn, but if you want to dress it up, go ahead and add nuts, melted chocolate, and/or a dash of cinnamon.
Every holiday season when I was growing up, my late grandmother made a double batch of this beloved homemade caramel corn. Friends and family would flock to the sweet and salty snack, and it never lasted more than a couple of days. Grandma was happy to repeat the process; serving it brought her so much joy.
Here’s Why You’ll Love This Caramel Corn
- Just 7 ingredients
- Salty, buttery, sweet
- Nothing beats the homemade flavor
- The caramel is chewy-crisp, not a break-your-teeth situation 😉
- Enjoy plain or add some flair with nuts, chocolate, or spices
- A make-ahead dessert recipe or sweet snack; the caramel corn keeps for days (if taste testers can resist!)
I cannot make this stuff fast enough. It’s INCREDIBLY irresistible, and a great holiday snack. In fact, it’s been tradition in our family to serve it along with a batch of spicy honey chex mix or seasoned pretzels as we decorate Christmas sugar cookies. Just a suggestion if you’re hosting a cookie decorating day and need some snack ideas!

Do not accidentally use baking powder. I repeat: do not use baking powder.
Use Air-Popped Popcorn
Once you have your popcorn ready, start the caramel sauce.
Caramel Coating for Caramel Corn
The caramel is a little different from my salted caramel sauce recipe, which is more like drizzle or garnish. Today’s caramel, however, is a caramel sauce that has some elasticity (thanks to the corn syrup), and holding power. Meaning it can cling nicely to the popcorn, and not melt off.
Combine the brown sugar, corn syrup, butter, salt, and cream of tartar together in a medium heavy-bottomed pot. Cook and stir over medium heat. Once the butter has melted and the mixture is bubbling around the edges, let it boil for around 4 minutes. If you have a candy thermometer (I use and love this one), use it here. Cook the mixture until it reaches 234–235°F (112–113°C).
As soon as the caramel comes off the heat, stir in the baking soda. The mixture will bubble up, almost double in volume, and appear frothy on the surface as you stir; this is normal and expected:
Pour over the popcorn, gently stir to combine, and then spread out onto a lined baking sheet:
Bake at 200°F (93°C) for 1 hour, stirring every 20 minutes. Baking the caramel corn is imperative and helps the caramel set evenly over the popcorn.
Bring to bake sales, tote along on road trips, or serve as a simple finger food at holiday parties—everyone loves this stuff. It’s also a wonderful option if you’re ever in need of gluten free dessert recipes.

Homemade Caramel Corn Recipe
Ingredients You’ll Need
Instructions
- Preheat the oven to 200°F (93°C). Line 1 or 2 12×17-inch baking sheets with silicone baking mats or parchment paper.
- Pour the popcorn into the largest bowl you have, or spread it onto the prepared baking sheets. (Either way is fine.)
- Combine the sugar, corn syrup, butter, salt, and cream of tartar in a medium saucepan over medium heat. Stir constantly as the butter melts and mixture comes to a simmer. Once simmering around the edges, allow to bubble, without stirring, for 4 minutes. (If you have a candy thermometer, the caramel should reach 234–235°F (112–113°C).)
- Remove caramel from heat and immediately stir in the baking soda. The mixture will bubble up, almost double in volume, and appear frothy on the surface as you stir; this is normal and expected. Be careful, it’s very hot.
- Pour the caramel over the popcorn and, with a large spoon or spatula, stir gently until all of the popcorn has been coated. Go slowly here and have patience; it requires quite a few turns of the spatula/spoon as the caramel begins to harden. If it’s not already, spread the popcorn evenly onto prepared baking sheet(s).
- Bake for 1 hour, gently stirring every 20 minutes.
- Allow to cool on the pan for at least 30 minutes. The caramel hardens as it cools. Once cool enough to handle, you can break apart any large clusters.
- Cover the popcorn tightly once cooled. This caramel corn stays fresh for up to 2 weeks in an airtight container, so it’s a great recipe to make ahead of time.
Frequently Asked Questions
If using microwave popcorn, look for a variety that's pretty plain, without butter, and not overloaded with salt. Buttered popcorn makes greasy caramel corn, and the caramel may not set.
Yes. Baking the caramel-coated popcorn helps to set the caramel sauce. By skipping this step, the caramel corn will become soggy.
Caramel corn will taste soft and chewy right out of the oven. Give it some time to cool. If it's still tasting soggy after 1–2 hours of cooling at room temperature, you may have under-baked the caramel corn. 1 hour in the oven is usually plenty. Additionally, be sure to cook the caramel on the stove for long enough. If you don't have a candy thermometer, you'll want to keep an eye on the clock—once it's bubbling, let it boil for 4 full minutes.
A candy thermometer isn't necessary for this recipe, but it's certainly helpful, as it gives the most accurate results. A candy thermometer shouldn't scare you away from a recipe; in fact, it's your biggest helper when it comes to candy recipes because it ensures precise results. If you have one, I recommend using it.
Yes, absolutely. You can add 1–2 cups of your favorite salted or unsalted nuts such as peanuts or cashews to the popcorn before you stir in the caramel sauce. To add chocolate, I recommend drizzling melted chocolate or white chocolate on the cooled caramel corn. You do not want to bake the caramel corn with the chocolate on top.
