Movie night deserves better than a plastic bag of butter-flavored dust. Infused salted caramel popcorn is the snack that hits every note at once: shatter-crisp caramel, flaky salt, and a slow-building glow from a little cannabutter stirred into the sauce. It comes together in about 45 minutes, most of which is your oven doing the work.
The trick to caramel corn that actually stays crunchy is baking it low and slow after the coating goes on. And because caramel is stirred off the heat at the end, it’s an easy place to fold in cannabutter without cooking off the good stuff.
Key takeaways
- Makes about 12 cups, or 12 servings of roughly 1 cup each.
- Uses 2 tablespoons of cannabutter plus 6 tablespoons of regular butter, so the caramel still sets properly.
- Typical home cannabutter lands around 9 mg THC per serving in this batch, but your butter’s potency is the only number that matters.
- Bake at 250°F for 45 minutes, stirring every 15, for caramel corn that stays crisp for a week.
- Start with half a serving, wait 90 minutes, and label the container clearly.
Ingredients
- 12 cups popped popcorn (about 1/2 cup unpopped kernels), unsalted
- 2 tablespoons cannabutter, softened
- 6 tablespoons unsalted butter
- 1 cup packed light brown sugar
- 1/4 cup light corn syrup
- 1/2 teaspoon fine sea salt
- 1/2 teaspoon baking soda
- 1 teaspoon vanilla extract
- Flaky sea salt, for finishing
Instructions
- Prep. Heat the oven to 250°F. Line two large rimmed baking sheets with parchment. Pop the popcorn, then pick out every unpopped kernel — they are the enemy of a good caramel corn. Divide the popcorn between the two sheets.
- Start the caramel. In a heavy saucepan over medium heat, melt the 6 tablespoons of regular butter with the brown sugar, corn syrup, and fine sea salt. Stir until the sugar dissolves.
- Boil. Bring to a boil and let it bubble without stirring for exactly 4 minutes. It will darken slightly and thicken.
- Take it off the heat. Remove the pan from the burner. Wait 30 seconds, then stir in the vanilla, the baking soda (it will foam up dramatically — that’s what makes the coating light), and finally the 2 tablespoons of cannabutter. Stir until fully combined and glossy.
- Coat. Working quickly, pour the caramel over both trays of popcorn in thin drizzles. Toss with two silicone spatulas until every piece is streaked with caramel. It will not look evenly coated yet — that happens in the oven.
- Bake. Bake for 45 minutes total, pulling the trays out to stir every 15 minutes. Rotate the trays top to bottom halfway through.
- Cool and salt. Spread the popcorn out on the parchment, sprinkle with flaky sea salt while still warm, and let it cool completely — at least 30 minutes. It crisps as it cools. Break up any clusters and store in an airtight container.
Dosing and safety
Do the math on your own butter, not on ours. As a worked example: a home batch of cannabutter made from 3.5 g of 18% THC flower, properly decarbed, tends to land somewhere around 400–450 mg of THC across 1/2 cup of butter — roughly 50–55 mg per tablespoon. This recipe uses 2 tablespoons, so about 110 mg spread across 12 servings, or roughly 9 mg THC per 1-cup serving. Extraction efficiency varies a lot at home, so treat that as an estimate and not a guarantee.
A few ground rules worth repeating every single time:
- Start low, go slow. Have half a serving first. Edibles typically take 30–90 minutes to come on, and longer if you’ve just eaten a big meal.
- Do not re-dose early. Wait a full two hours before deciding you want more.
- Label it. Caramel corn looks exactly like caramel corn. Put it in a labeled, sealed container and store it well out of reach of kids and pets.
- Stir well. Uneven mixing is the most common cause of a serving that hits much harder than expected — take the extra minute in step 5.
- Know your local laws. Cannabis rules differ by state and city. Only make this where it’s legal for you to do so, and never share with anyone under 21.
Frequently asked questions
Can I use canna-oil or a tincture instead of cannabutter?
Yes. Swap the 2 tablespoons of cannabutter for 2 tablespoons of canna-coconut-oil, or stir in a measured dose of tincture at the same off-heat moment in step 4. Tincture is actually the easiest option to dose precisely, since the mg per milliliter is usually printed on the bottle.
Why did my caramel corn turn out chewy instead of crunchy?
Almost always an underbake. The full 45 minutes at 250°F is what drives off the moisture. It also needs to cool completely, spread in a single layer — it is still soft when it comes out of the oven and firms up as it sits.
How long does it keep, and does the potency fade?
Stored airtight at room temperature it stays crisp for about a week. THC degrades slowly over time and with light and heat exposure, so keep the container sealed and out of the sun. Potency will not change noticeably over a week.
Can I halve the cannabutter?
Absolutely, and it’s a good idea if you’re new to edibles or serving guests. Use 1 tablespoon of cannabutter and 7 tablespoons of regular butter for roughly 4–5 mg per serving. The caramel behaves the same either way.
