Classic Peanut Brittle Recipe
I really wanted to name this Beth’s fabulous, tasty, buttery, delicious, addicting Peanut Brittle. BUT, Google only gives me 60 characters for a title so I just kept it simple. This is my sister-in-law, Beth’s, recipe for peanut brittle. She is a peanut brittle pro and has been making this delectable candy for over 20 years now.
If you’re new to candy making, then I suggest starting with this Peanut Brittle recipe. It’s really simple to make. Beth wanted me to share three musts with this recipe:
- You must have a candy thermometer to make this recipe.
- You must be exact with the temperatures.
- You must butter the cookie sheet and NOT use a nonstick cooking spray.
Peanut Brittle Recipe Ideas:
- Drizzle it with white or dark chocolate after it’s been broken into pieces.
- Use other nuts like pistachios, hazelnuts, cashews, pecans, almonds, or macadamia nuts. You can even use pumpkin seeds instead of nuts!
- Right after pouring the brittle out onto the buttered cookie sheet, sprinkle it with some crumbled bacon. This sweet and salty combination takes on a new level of irresistible!
- Make cinnamon brittle by adding 1 teaspoon of cinnamon the same time you add in the baking soda.
- Crush up the brittle nice and fine and cover freshly dipped caramel apples with it.
- Make the brittle SPICY by adding a ½ teaspoon of cayenne pepper at the same time as the baking soda.
- Sprinkle some sea salt on top of the brittle to get a fantastic salty-sweet sensation!
Common Peanut Brittle Questions answered!
What is the purpose of adding baking soda to peanut brittle?
Once the baking soda is added to the hot mixture it bubbles up and the mixture becomes somewhat airy. (You can see this in my recipe video below). When the brittle sets, those air bubbles dry and give the candy its distinctive airy texture.
How long does it take for peanut brittle to dry?
About 30 minutes.
How do you store peanut brittle?
Peanut brittle must be stored in a cool, dry place in either an air-tight container or Ziploc bag.

- Make sure you have all of your ingredients measured out and ready before you begin making this recipe. The recipe moves quickly and you won’t have time to measure out the ingredients in between steps.
- IT will keep in an airtight container at room temperature for about 2 weeks…but I bet it won’t last that long!
- While Peanut Brittle is most popular around the holidays, I like making and gifting it at other times of the year, too like Valentine’s Day.
- Other treats that I like to gift right along with brittle is my Almond Roca Brittle and Chocolate Chip Cookie Dough Truffles!
