A bold twist on classic peanut brittle, this Jalapeño Peanut Brittle delivers crisp caramelized sugar, toasted peanuts, and a subtle heat that builds with every bite. The sweetness balances the spice, creating a candy that’s perfect for gifting, entertaining, or adding a gourmet touch to dessert boards.

Ingredients

• 2–3 fresh Jalapeño peppers, seeded and finely diced
• 2 cups granulated sugar
• 1/2 cup water
• 1 cup light corn syrup
• 2 cups salted peanuts
• 2 Tablespoons unsalted butter
• 2 teaspoons baking soda
• 1 teaspoon pure vanilla extract

Preparation

1. Prepare the Pan: Line a 9×13-inch baking pan with parchment paper or lightly grease a rimmed baking sheet. Set aside.
2. Start the Sugar Base: In a heavy-bottomed saucepan over medium heat, combine sugar, water, and corn syrup. Stir until the sugar dissolves and the mixture begins to boil.
3. Cook to Soft Crack Stage: Attach a candy thermometer to the side of the pan. Cook, stirring occasionally, until the mixture reaches 250°F.
4. Add Peanuts and Jalapeño: Stir in the peanuts and diced Jalapeño. Continue cooking, stirring constantly, until the mixture reaches 300°F (hard crack stage).
5. Finish the Brittle: Immediately remove from heat. Quickly stir in the butter, baking soda, and vanilla extract. The mixture will foam and lighten in color.
6. Spread and Cool: Pour the hot mixture onto the prepared pan. Spread thinly with a heatproof spatula as quickly as possible. Allow to cool completely at room temperature, about 1 hour.
7. Break and Store: Once fully hardened, break into pieces. Store in an airtight container at room temperature for up to 2 weeks.

Cook’s Notes

• Use gloves when handling Jalapeños to avoid irritation.
• For milder heat, use 1–2 peppers and remove all seeds and membranes. For more spice, leave in some seeds.
• Humidity can affect texture. For best results, make brittle on a dry day.
• Work quickly once the mixture reaches 300°F, as it sets fast.

Serving Suggestions

• Serve alongside dark chocolate for a sweet-heat contrast.
