Ingredients in Peanut Brittle
- Sugar - you’ll need white granulated sugar for this recipe.
- Corn Syrup - this helps make sure the sugar syrup doesn’t crystallize as it cooks, making it grainy.
- Water - this is added to the sugar mixture to help ensure that it cooks evenly.
- Peanuts - I like to use raw peanuts, but salted peanuts and roasted peanuts would also work great.
- Butter - it’s a good idea to cut your butter into pieces so that it will melt quickly in the hot syrup.
- Baking Soda - this creates miniscule bubbles in the brittle, helping to give it it’s characteristic texture.
- Vanilla Extract - pure vanilla extract tastes best.
How to Make Peanut Brittle
- Cook the sugar syrup. In a large saucepan over medium heat, add the sugar, corn syrup and water. Cook over medium heat, stirring occasionally until the sugar is dissolved.
- Add the peanuts. Add the peanuts and stir frequently until the temperature reaches 300 degrees F on a candy thermometer.
- Stir in the rest. Remove from heat and stir in baking soda, butter, salt and vanilla. Stir just until combined.
- Pour mixture onto the prepared baking sheet. Immediately pour the mixture as evenly as possible onto a large buttered baking sheet (or a baking sheet covered in parchment paper). Do not spread.
- Cool completely. Let the mixture cool to room temperature (at least 30 minutes) then break into 2" pieces using your fingers.
- Serve. Serve immediately or store in a cool place in a covered container. Enjoy!
Frequently Asked Questions
You’ll want to store your brittle inside an airtight container in a cool, dark place. Room temperature is preferred over the fridge because there is less chance for moisture to get to it.
If you don’t add baking soda to your Peanut Brittle, you’ll have a hard time eating it. The baking soda creates thousands of tiny little bubbles in the mixture making the finished texture light and airy.
If you don’t have a candy thermometer, the next best thing is a meat thermometer. Don’t have that either? Try dipping a spoon into a small amount of mixture then plunging it into very cold water. If the brittle threads, it’s ready.
The stickiness in sugar candies means there is too much water present. Either you didn’t cook the sugar mixture all the way to 300 degrees F or you introduced it to the refrigerator where water forms more readily.
Storing Homemade Peanut Brittle
Store your Peanut Brittle in an airtight container at room temperature, in a cool dark place. If stored properly, it should last for up to 2 weeks.
