Brown Butter Popcorn Brittle Recipe

You can make candy at home — and it’s easier than you think. Turn buttered popcorn into a crunchy, buttery popcorn brittle with this simple recipe.

I had been wanting to make popcorn brittle for a very long time, and when Popcorn, Indiana sent me a bag of their movie-theatre-style popcorn, it felt like the perfect nudge to finally try it. I don’t mention everything I receive, but this popcorn earned its place in a recipe because it really is that good.

I’m somewhat of a popcorn enthusiast, and I often buy pre-popped popcorn when I’m feeling lazy. Store-bought pre-popped varieties can be overly salty or dense with unpopped, hard kernels that are unpleasant to bite into. What I like about the Popcorn, Indiana Movie Theatre popcorn is that it has fewer partially popped kernels, a lighter salt level compared with many brands, and it’s made with clarified butter. The ingredient list is short — just popcorn, canola oil, clarified butter, and salt — and it tastes closer to real buttered popcorn than some overly processed microwave or pre-popped brands.

I tested this buttered popcorn brittle recipe extensively to find the best balance of caramelization and butter flavor. Here are a couple of things I learned from making multiple batches:

• If you add too much popcorn, the candy becomes more like caramel corn than brittle — the texture softens and it won’t snap as well.
• Darker, more deeply caramelized sugar makes a richer brittle, but it also masks the delicate buttered popcorn flavor. For this version, a light-to-medium caramel color preserves the popcorn’s buttery notes.

For a straightforward, delicious popcorn brittle, I kept the recipe simple: water, light corn syrup, granulated sugar, a bit of extra butter, salt, and lightly crushed buttered popcorn. The corn syrup helps prevent the sugar from crystallizing while you cook. We avoid baking soda here because its residual flavor can interfere with the pure popcorn taste. Aim for a light-to-medium caramel color so the brittle stays crisp without overwhelming the buttered popcorn flavor. The amount of popcorn you add is up to you — about 5 cups will give a chewier, caramel-corn-like result, while roughly 1–1.5 cups yields a firmer, more brittle-style candy.

📖 Recipe

Buttered Popcorn Brittle

Make a crunchy, buttery brittle by folding popcorn into a light caramel. This recipe is quick and makes a crisp snack that highlights real butter flavor.

Equipment

• Sheet pan
• Candy or instant-read thermometer
• Rolling pin (optional, for crushing popcorn)

Ingredients

• 60 grams water
• 75 grams light corn syrup
• 200 grams granulated sugar
• 30 grams unsalted butter
• 20 grams popcorn, crushed a little (use high-quality buttered popcorn)
• About 0.625 mL fine kosher salt (adjust if using table salt)

Instructions

1. Line a sheet pan with parchment paper or foil and grease it lightly with nonstick spray or a little butter. Parchment is my preference.
2. In a medium saucepan, combine the water, light corn syrup, and granulated sugar. Stir over medium heat until the sugar dissolves, then stop stirring and bring the mixture to a boil. Attach a candy thermometer and heat until the mixture reaches 300°F (150°C), the hard-crack stage.
3. Add the unsalted butter, stirring to combine, and continue to cook until the temperature reaches 330–340°F (166–171°C). The caramel will develop a light golden color. Remove the pan from the heat immediately.
4. Working quickly, stir in the crushed buttered popcorn and the salt until evenly coated. Transfer the hot mixture to the prepared sheet pan, cover with another layer of parchment, and roll or press to your desired thickness.
5. If you prefer neat pieces, grease a chef’s knife and score the surface while the brittle is still warm to make cutting easier. When the brittle is fully cooled and set, snap it into pieces and store in an airtight container at room temperature.

Notes

• This recipe calls for fine kosher salt. If you use table salt, use about half the amount to avoid over-salting.
• Adjust the popcorn amount to control texture: more popcorn gives a chewier, caramel-corn style; less popcorn produces a crisp, thin brittle.
• For the best popcorn flavor, use a popcorn you enjoy eating on its own — real butter or clarified-butter-flavored popcorn works particularly well.

Popcorn, Indiana provided the popcorn used for testing this recipe. Their movie-theatre-style popcorn worked well because it has fewer partially popped kernels, a balanced salt level, and a buttery flavor that comes through in the brittle. I only highlight products I think are worth mentioning.
