A Classic Candy
This peanut brittle recipe is one of our FAVORITE homemade candies!
It’s been grandpa’s favorite for as long as we can remember and now a favorite of our own. We LOVE the crunchy texture and sweet and salty flavor of this classic old-fashioned treat! We make this a couple of times a year, especially at Christmas to gift to friends and neighbors (and so we can munch on it).
It is actually a really simple candy. There are few ingredients, simple steps, and less than 30 minutes of actual work!!
For more crunchy favorites try our famous Toffee Recipe and Christmas Crack Recipe.
WHY WE LOVE IT:
- Familiar flavor. It’s perfectly crispy, filled with roasted peanuts, and has a sweet buttery, flavor.
- A classic candy. This candy has been a beloved confection for years, and is a go-to treat (especially around Christmas)!
- Easy to make. With just a few simple steps, it’s ready to enjoy in under an hour!
Ingredients
PREP TIME: 10 minutes
COOK TIME: 15 minutes
COOL TIME: 30 minutes
- 1 cup white sugar
- ½ cup light corn syrup
- ¼ cup water
- 1 cup peanuts (no skin) – Blanched peanuts are skinless. If using unroasted peanuts, add them to the mixture when melting the sugar, corn syrup, and water. This way they’ll cook and soften. Salted peanuts work too.
- 2 tablespoons unsalted butter – Cutting the butter into cubes first helps it melt better.
- 1 teaspoon vanilla extract
- ¼ teaspoon salt – omit if using salted butter
- 1 teaspoon baking soda
How to Make Peanut Brittle
- PREP. Make sure all ingredients are ready and measured out before starting. Some steps require quick action, so this will help the process.
- Preheat the oven to 170°F.
- Grease a 10×15 jelly roll pan or rimmed baking sheet (or cookie sheet) with at least 1-inch tall sides. Set aside.
- SUGAR MIXTURE. Heat a large pot over medium heat (The mixture will boil up a lot so use one that’s bigger than you think you’ll need.)
- Bring 1 cup sugar, ½ cup corn syrup, ¼ teaspoon salt, and ¼ cup water to a boil. Stir until the sugar is dissolved. When the liquid looks clear, that indicates the sugar has dissolved.
- While the mixture is heating up, add the jelly roll pan to the preheated oven so it can warm up.
- PEANUTS. Add a candy thermometer to the sugar mixture. When the temperature reads 250°F, stir in 1 cup of peanuts. Cook on medium-low heat at a steady boil until the temperature reaches the hard crack stage of 300°F (takes about 10-13 minutes).
- If you don’t have a thermometer, drop a small amount of the candy mixture into a bowl of cold water, if it separates into hard and brittle threads, it’s ready.
- COMBINE. Once the mixture reaches 300°F, this is the fast part. Remove from heat and immediately stir in 2 tablespoons butter, 1 teaspoon baking soda, and 1 teaspoon vanilla.
- The brittle will lighten up in color but will return to a golden-beige color when it cools.
- SPREAD. Working quickly, pour back and forth onto the cookie sheet. Using oven mitts, move the pan around until the mixture spreads out. The recipe will not fill the whole pan, do not spread with a knife or spatula.
- COOL. After pouring/spreading, allow it to sit at room temperature for 10 minutes to cool. Then place it in the refrigerator for another 20-30 minutes.

Store in an airtight container at room temperature for a week or longer. We don’t recommend freezing or refrigerating because it can lose its crunch.
