Ingredients

10–11 cups (about 70–75g) air-popped popcorn*
1 cup (200g) packed light brown sugar
1/4 cup (80g) light corn syrup*
1/2 cup (113g) unsalted butter
1/2 teaspoon salt
1/8 teaspoon cream of tartar*
1/2 teaspoon baking soda

Instructions

Step 1: Preheat the oven to 200°F (93°C). Line one or two 12×17-inch baking sheets with silicone baking mats or parchment paper.
Step 2: Place the popcorn in the largest bowl you have, or spread it evenly onto the prepared baking sheets.
Step 3: In a medium saucepan over medium heat, combine the brown sugar, corn syrup, butter, salt, and cream of tartar. Stir constantly as the butter melts and the mixture starts to simmer. Once it begins bubbling around the edges, let it cook without stirring for 4 minutes. If using a candy thermometer, the caramel should reach 234–235°F (112–113°C).
Step 4: Remove the saucepan from heat and immediately stir in the baking soda. The mixture will bubble and froth—this is normal. Be careful, as it will be very hot.
Step 5: Pour the caramel sauce over the popcorn. Using a large spoon or spatula, gently stir until all the popcorn is evenly coated. Take your time, as the caramel will begin to harden. Spread the coated popcorn evenly on the prepared baking sheet(s) if you haven’t already.
Step 6: Bake in the preheated oven for 1 hour, stirring gently every 20 minutes to ensure even coating.
Step 7: Remove from the oven and allow the caramel corn to cool on the baking sheet for at least 30 minutes. The caramel will harden as it cools. Once cool enough to handle, break apart any large clusters.
Step 8: Store the cooled caramel corn in an airtight container.

Tips & Variations

For extra flavor, add a teaspoon of vanilla extract to the caramel sauce after removing it from heat.
Use salted butter and reduce the added salt for a slightly saltier, balanced flavor.
Try mixing in nuts like pecans or almonds before baking for extra crunch.
If you don’t have light corn syrup, you can substitute with an equal amount of honey or maple syrup, though this may slightly change the texture.

Storage

Store caramel corn in an airtight container at room temperature. It stays fresh for up to 2 weeks. Avoid refrigeration, as moisture can make the caramel sticky or soggy. To refresh slightly hardened caramel corn, warm it gently in a low oven for a few minutes before serving.

How to Serve

A rectangular metal container lined with white parchment paper holds a large pile of caramel popcorn. The popcorn pieces are covered with a shiny, golden caramel coating, giving them a glossy texture. Each popcorn piece is fully coated, with some showing a mix of golden caramel and white popcorn beneath. The container edges have a red and white striped pattern. The whole scene is set on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use microwave popcorn instead of air-popped popcorn?

Yes, microwave popcorn can be used, but avoid flavored or salted varieties. Plain popcorn works best for coating with caramel.

Why does the caramel bubble and foam when baking soda is added?

Adding baking soda reacts with the acidic ingredients, creating carbon dioxide bubbles. This aerates the caramel, making it lighter and easier to coat the popcorn evenly.
