Ingredients

1/4 cup (60ml) vegetable oil (not required if air popping with a popcorn maker)
1/3 cup popping corn (about 10 cups popped popcorn, see note below)
100g / 7 tbsp unsalted butter
1 cup (220g) brown sugar, packed
1/2 cup (170g) light corn syrup (can substitute glucose or honey, see tips)
1/2 tsp salt
1 tsp vanilla extract
1/2 tsp baking soda

Instructions

Step 1: Heat oil in a large pot over medium heat. Add a few popcorn kernels and wait until they pop, then quickly remove them.
Step 2: Add the remaining popcorn kernels to the pot. Lift the pot off the heat and shake to distribute the kernels evenly. Cover with a lid. Return to heat and once popping starts, gently shake the pot once more.
Step 3: Remove the pot from heat when the popping slows down (about when you can count to 3 between pops). Transfer the popped corn to a very large bowl. You should have about 10 cups of popcorn.
Step 4: Preheat your oven to 110°C (230°F).
Step 5: In a saucepan over medium heat, melt the butter.
Step 6: Add the brown sugar, corn syrup, and salt to the melted butter. Stir gently until just combined.
Step 7: Allow the mixture to come to a boil, then simmer without stirring for 4 minutes.
Step 8: Remove the saucepan from heat. Quickly whisk in the vanilla extract and baking soda. The caramel will foam and increase in volume.
Step 9: Immediately pour the caramel over the popcorn. Toss gently to coat the popcorn evenly as the caramel starts to cool and harden.
Step 10: Spread the coated popcorn onto two baking trays in an even layer.
Step 11: Bake for 45 minutes, tossing the popcorn every 10 minutes. The caramel will remelt during the first few tosses, ensuring an even coating. If using glucose or honey instead of corn syrup, extend baking time by an additional 15 minutes.
Step 12: Remove the trays from the oven and let the popcorn cool completely. Once cooled, break into pieces and serve.

Tips & Variations

For lighter caramel coverage, use 10 cups of popped popcorn as noted. This gives a balanced coating without too much sweetness.
You can substitute corn syrup with glucose or honey, but be aware that baking time may need to be longer to properly crisp the coating.
If you prefer air-popped popcorn, skip the vegetable oil for a lighter result.
Adding a pinch of cinnamon or a sprinkle of sea salt on top before baking adds an interesting flavor twist.

Storage

Store cooled caramel popcorn in an airtight container at room temperature. It will stay crisp for 2 to 3 weeks. To refresh slightly softened popcorn, you can reheat it gently in a low oven (around 110°C / 230°F) for 5 to 10 minutes before serving.

How to Serve

FAQs

Can I use microwave popcorn for this recipe?

Microwave popcorn is not recommended because it often contains added butter and salt that can interfere with the caramel coating process. Using plain popping corn gives you the best results.

Why does the caramel foam when I add baking soda?

Baking soda reacts with the acidic ingredients in the caramel, creating bubbles that aerate the mixture. This foaming effect helps produce a lighter, crispier caramel coating on the popcorn.
