Jalapeño Peanut Brittle
If you’re a heat aficionado, take peanut brittle to the next level by using jalapeño peppers.

Tips for making delicious peanut brittle
- Prepare Your Workspace: Have all ingredients measured and ready before you start, as the process moves quickly once the sugar melts.
- Use a Heavy-Bottomed Pan: This ensures even heat distribution and prevents hot spots that can cause burning.
- Use a Candy Thermometer: Monitor the temperature closely; peanut brittle typically cooks to about 300 degrees F (hard crack stage).
- Stir Carefully: When melting sugar, stir gently to prevent crystallization. Once the mixture begins to boil, avoid unnecessary stirring.
- Incorporate Baking Soda at the Right Time: Add baking soda when the mixture reaches the correct temperature to create the characteristic airy texture.
- Work Quickly to Pour and Spread: Once the mixture is ready, pour it onto a prepared baking sheet and spread it evenly before it cools.
- Use Parchment or Silicone Baking Mats: These make it easier to remove the brittle once cooled and prevent sticking.
- Cool Completely Before Breaking: Let the brittle cool at room temperature until hard, then break into pieces.
- Store Properly: Keep in an airtight container at room temperature to maintain freshness.
Jalapeño Peanut Brittle

1 1/4 cups granulated sugar
1/2 cup raw peanuts

1/4 teaspoon vanilla extract
1/4 teaspoon almond extract
3 drops green food coloring (optional – I don’t use it)
1/2 teaspoon baking soda
Instructions
- Generously butter a 15 x 10 x 1 inch jellyroll pan. Set aside.
- In a skillet melt 1 tablespoon of the butter; add jalapeños and peanuts, and cook over low heat until peppers are soft.
- In a saucepan, combine sugar and syrup and bring to a boil over medium heat.
- Add jalapeños and peanuts. Stir well, and cook until mixture reaches the soft crack stage on a candy thermometer. Remove from heat.
- Blend in remaining 1 tablespoon butter, vanilla extract, almond extract and food coloring (if using) until well mixed.
- Sprinkle baking soda evenly over the cooked mixture and stir well. When foamy, pour immediately onto the prepared jellyroll pan. Spread out into a thin layer.
