homemade caramel corn!

Popcorn is our go-to snack of choice for movie nights. When we’re craving something sweet and crunchy it’s always caramel popcorn!

You can find packaged caramel popcorn at lots of retail stores, but the real deal is HOMEMADE popcorn made in your kitchen. It tastes 100x better and fresher – and makes the perfect treat!

We often like to air-pop our kernels for maximum freshness and flavor, but you could easily start with pre-popped corn or microwave a couple of bags. The sweet caramel coating is just 5 ingredients and cooks up in the microwave in minutes! It’s a quick dessert – easy to whip up seconds or thirds! 😉

Crunchier than our Caramel Marshmallow Popcorn, this caramel popcorn recipe is undeniably delicious!

WHY WE LOVE IT:

  • Great all year long. It’s a favorite for parties and movie nights, but also great to gift for birthdays and holidays like Christmas!
  • Yum factor! Homemade is always better than store-bought and this is caramel perfection!
  • Ready in minutes. This is a deliciously easy dessert with its simple ingredients and easy instructions.

Ingredients

  • 2 (3.29-ounce) bags plain popcorn Use microwave bags of popcorn or a popcorn maker. You’ll need about 9-10 tablespoons of popcorn kernels or 18-20 cups of popped plain popcorn.
  • ¾ cup butter We use unsalted butter but salted butter can be used instead.
  • ⅓ cup white Karo syrup – or another brand of light corn syrup
  • 1½ cups brown sugar – We use light brown sugar, but dark brown sugar can be used.
  • ¾ teaspoon salt Reduce if using salted butter.
  • ¾ teaspoon baking soda
  • variation Drizzle chocolate or white chocolate over the caramel popcorn while it’s cooling on the cookie sheet, or add chopped nuts.

How Much Popcorn to Make

A 3.25 bag of popcorn contains 2.5 servings, each serving is 2 tablespoons of kernels which makes 4.5 cups of popped corn. For this recipe, you would need 2 bags which is 9-10 tablespoons of kernels or 18-20 cups of popped popcorn.

How to Make Caramel Popcorn

  1. PREP. Make 2 bags plain popcorn and place it in a large bowl. Remove unpopped kernels.
    • A good trick is to pour your popcorn over a cooling rack. The un-popped kernels will fall through the cracks and the popcorn will stay on top.
  2. CARAMEL. Using a medium-sized microwave-safe bowl add ¾ cup butter, 1½ cups brown sugar, ⅓ cup karo syrup, and ¾ teaspoon salt. Heat in the microwave for 2 minutes.
    • Add ¾ teaspoon baking soda to the melted ingredients. The mixture will foam up. Stir well.
    • The longer the caramel topping cooks, the crunchier it will be. This caramel corn recipe is meant to have more of a crunch, but if it is too hard to eat, then it was cooked for too long.
  3. COAT. Pour over popcorn and toss together evenly coating all of the pieces.
    • Place the coated popcorn in the microwave for 1 minute and then stir. Place it back into the microwave and heat for another minute. For crunchier popcorn, heat it for another minute.
  4. ENJOY! Line a baking pan with parchment paper and spread the coated popcorn on it to cool. Break apart and enjoy this caramel popcorn recipe!

Stove top directions

  1. In a medium saucepan, melt the butter over medium heat. Add the brown sugar, Karo syrup, and salt and stir while the mixture comes to a boil.
  2. Boil the mixture for 5 minutes without stirring it. Add the baking soda and mix to combine everything and remove from the heat.
    • To avoid crystallization, be cautious about scraping the sides of the pot and accidentally stirring in the crystalized caramel.
  3. Drizzle over plain popcorn in a large bowl, toss to evenly coat, and spread on a lined cookie sheet to cool completely.

    DO NOT RECOMMEND
    Recipe makes no sense. Blog talks about doing it over the stove top, while recipe and instructions talk about making caramel in microwave. Also says that it is free of corn syrup but calls for 1/3 Karo syrup.

    1. Lil'Luna Team says:

      Thanks for the feedback and for giving the recipe a try.

  2. Moriah says:

    I’m a bit confused. The directions and the recipe are completely different. Which way is best?

  3. Jamie says:

    Is it possible to make caramel popcorn with Berry Hill Creamy Caramel dipping sauce?

    1. Lil'Luna Team says:

      You know, I haven’t tried making it with caramel dip before. You could certainly give it a try. There might be recipes out there specifically using a dip too. You’ll have to let us know how it turns out if you make it with the dip!

    1. Kristyn Merkley says:

      You are so welcome! Happy to hear that! Thank you for trying it!

  6. Jacqui says:

    Why does it say only 5 ingredients and no corn syrup, then the recipe has more than 5 ingredient,s one of them being corn syrup?

  7. Sarah says:

    You said this recipe is made without corn syrup but it has karo syrup, which is corn syrup, listed as an ingredient. Do you omit it?

  8. Lori Duncan says:

    I am a little confused as there is corn syrup in the recipe that says its a corn syrup free??
