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 into 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 begins to simmer. Once it starts simmering around the edges, let it bubble without stirring for 4 minutes, or until it reaches 234–235°F (112–113°C) on a candy thermometer.
Step 4: Remove the caramel from heat and immediately stir in the baking soda. The mixture will bubble up and become frothy. Be careful as it will be very hot.
Step 5: Pour the caramel over the popcorn. Using a large spoon or spatula, gently stir until all the popcorn is coated evenly. Work slowly to ensure the caramel begins to harden on the popcorn. If not already done, spread the coated popcorn evenly on the prepared baking sheet(s).

Step 6: Bake for 1 hour, stirring gently every 20 minutes to maintain even coating and prevent burning.
Step 7: Remove from the oven and allow the caramel corn to cool on the pan for at least 30 minutes. The caramel will harden as it cools. Break apart any large clusters once it is cool enough to handle.
Step 8: Store the cooled caramel corn in an airtight container. It will stay fresh for up to 2 weeks.

Tips & Variations

Use silicone mats or parchment paper to prevent sticking and make cleanup easier.
For a nutty twist, add 1 cup of roasted nuts to the popcorn before pouring on the caramel.
Be patient when stirring the caramel into the popcorn; rushing can cause clumps instead of an even coating.

If you don’t have cream of tartar, you can omit it, but it helps stabilize the caramel.

Storage

Store caramel corn in an airtight container at room temperature for up to two weeks. Avoid refrigerating, as moisture can soften the crispness. To refresh slightly softened popcorn, spread it on a baking sheet and warm in a 250°F (120°C) oven for 5–10 minutes.

How to Serve

A large silver baking tray holds a single thick layer of caramel popcorn, each popcorn piece coated in a shiny golden-brown caramel glaze with some white popcorn parts peeking through, spread evenly across a red silicone mat beneath. The tray sits on a white marbled surface with a blue and white patterned cloth partially visible on the bottom left corner. photo taken with an iphone --ar 4:5 --v 7

FAQs

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

Yes, you can use microwave popcorn, but avoid varieties with butter or strong seasoning. Plain, lightly salted microwave popcorn works best to achieve an even caramel coating.

What if I don’t have corn syrup?

You can substitute corn syrup with honey or maple syrup, but the texture of the caramel may be slightly different. Corn syrup helps prevent crystallization and gives a smooth finish.
