From Nicky: “I’ve made this caramel corn a half dozen times already, it is AMAZING! I usually double the amount of popcorn to caramel and it still covers the popcorn just enough. I bag it up and hand it out as gifts for the holiday. There’s never enough to go around as it gets snacked on immediately!! Thanks“

Ingredients You’ll Need
Here are a few notes on some of the key ingredients to make this caramel corn. Jump to the recipe card below for the exact measurements.
- Popcorn kernels: Either white or yellow kernels will work! I highly recommend popping them in a good air-pop popcorn machine so they’re not coated in any oils or additives, making them perfect for mixing with the caramel sauce. I also think it yields bigger pieces than microwave or stove-top popped popcorn.
- Butter: Butter adds richness and flavor to the caramel while helping it stick to the popcorn. A hefty 4 sticks is needed for this recipe, but it makes a big batch!
- Brown sugar: Light brown sugar adds to the caramel corn’s sweetness and gives it a nice hint of molasses flavor for depth.
- Light corn syrup: I don’t use corn syrup often but it’s very helpful for special treats like caramel corn and homemade caramels. It keeps the brown sugar from crystallizing and guarantees a smooth caramel texture. I usually buy organic corn syrup.
- Baking soda: This is the secret ingredient! When added to hot caramel, baking soda causes it to foam up which helps the caramel stick to the popcorn so much better!
- Salt: A good pinch of salt is key to delicious caramel corn to balance out the sweetness. I highly recommend Kosher salt!
How to Make the Best Caramel Corn
Here’s an overview of how to make this caramel corn. You can jump to the recipe for the full instructions!
- Pop the popcorn: Pop the kernels (preferably in an air-pop popcorn machine) and then divide the popcorn evenly between 2 large baking sheets lined with silicone baking mats or parchment paper. Try to leave behind as many unpopped kernels as possible!
- Boil the caramel: In a medium saucepan, slowly melt together the butter, sugar, light corn syrup, and salt over medium heat. Once it comes to a full boil, continue to boil it for 5 minutes. Stir constantly!
- Add the baking soda: Remove the caramel from the heat and carefully mix in the baking soda. The caramel will expand when you add it in.
- Coat and bake: Use the caramel to coat all of the popcorn on both baking sheets. Mix the caramel and popcorn well for even coating. Bake for 1 hour, stirring every 15 minutes along the way. Cool and enjoy!
Make-Ahead/Storage/Freezing Instructions
To Make-Ahead: This is a great make-ahead recipe as it keeps at room temperature for up to 1 week when stored properly. I love using it for gifts during the holidays!
To Store: Store in an air-tight container or sealed bag at room temperature. Make sure you don’t pack it too tightly! It will stay crunchy and delicious for up to 1 week.
To Freeze: Store in an air-tight container or sealed bag in the freezer for up to 3 months. Thaw at room temperature for at least 1 hour before opening. If it feels a bit soft, place on a lined baking sheet and crisp it up in the oven at 250°F for about 10-15 minutes. Cool before enjoying!
Why is my caramel corn not crunchy?
Your caramel corn won’t turn out crunchy if the syrup is too thick. (You’ll have a chewy caramel corn instead.) To get a nice crunchy caramel corn, try heating the syrup longer to thin it out.
How do you keep caramel corn from getting soggy?
You can avoid soggy caramel corn by baking it at a low temperature over a long period of time. Make sure to stir the caramel corn to ensure it evenly bakes and is well coated with the syrup.
Why is my caramel corn gritty?
Your caramel corn will turn out gritty when the sugar crystals clump together. This can happen if the sugar doesn’t fully dissolved during cooking or if the mixture is stirred inconsistently, among other reasons. The light corn syrup and baking soda in this recipe both help prevent the sugar from crystallizing.
Why do you add baking soda to caramel?
Adding baking soda to caramel breaks apart the sugar molecules and create a softer caramel syrup texture. The baking soda will create a chemical reaction with the acid in the brown sugar and corn syrup to create bubbles. After the mixture creates tiny carbon dioxide air bubbles, it will cool down and create a softer texture. This is the perfect texture for evenly coating your popcorn.
Recipe Tips
- Stirring this easy homemade caramel corn every 15 minutes while it’s baking is key for getting every piece coated with caramel.
- Skip the bags of microwave popcorn for this recipe. Homemade caramel corn will turn out best if you make the popcorn in an air-pop popcorn machine. Even with this extra step, it’s still one of those easy recipes you’ll come back to again and again!
- If you’re unsure of when to take the caramel mixture off of the heat, you can use a candy thermometer. Remove from heat once the mixture reaches 250°F degrees.

Just made this popcorn!! Wow! Delicious! I used dark brown sugar-A MUST! And I actually doubled the amount of popcorn because as one other comment said, it’s a lot of butter. Still had tons of caramel. Can’t wait to pack in small gift bags tomorrow morning! Thanks for a great recipe! (Found you on Pinterest!)

I’m so glad you like it!
Sounds delicious! Thinking of making a batch to put in favor bags for my daughter’s birthday. There are two kiddos that can’t eat dairy. What’s a good substitute for the 4 sticks of butter that works well and still tastes great for caramel corn?
I see other recipes using way less butter with way more popcorn. I think I’ll shy away from this one.
It’s not healthy – but very delicious!
You say “sticks of butter”. Is that 2 cups in total, each stick being half a cup?
Yes 2 cups total.
Sounds so good!
Is there anything I can substitute for the corn syrup?
Unfortunately there’s not!
What a fun video. Brought back memories of childhood and making this at Halloween.
Thanks Heather! Caramel corn really is so fun to make this time of year!
Kids of all ages love these.
Yes they do! 🙂
