Vintage Peanut Brittle Recipe
Introduction
Vintage Peanut Brittle is a timeless, crunchy treat that combines the rich flavor of roasted peanuts with a perfect balance of sweet caramelized sugar. This classic candy is simple to make and sure to satisfy your sweet tooth with its delightful texture and buttery notes.

Ingredients
- ¾ cup water
- 2 cups granulated sugar
- 1 cup light corn syrup
- 6 tablespoons unsalted butter, cubed
- 2 ½ cups salted dry roasted peanuts
- 2 teaspoons vanilla extract
- 1 teaspoon baking soda
Instructions
- Step 1: Line a large (18×26 inch) sheet pan with lightly buttered parchment paper or a silicone mat to ensure easy removal once the brittle hardens. Set aside.
- Step 2: In a large (3-4 quart) stainless steel sauce pot, combine water, granulated sugar, and corn syrup. Gently stir to blend. Attach a candy thermometer to the pot, making sure it doesn’t touch the bottom and the bulb is submerged in the syrup for accurate temperature readings.
- Step 3: Heat the mixture over medium heat and boil undisturbed until the temperature reaches 250°F (firm ball stage). This process will take about 20-25 minutes depending on your stovetop.
- Step 4: Stir in the cubed butter slowly until fully melted, then mix in the peanuts evenly.
- Step 5: Continue cooking and stirring the mixture occasionally until it reaches 300°F-305°F (hard crack stage), about 10-15 minutes. Remove from heat immediately to prevent burning.
- Step 6: Quickly stir in the vanilla extract and baking soda until well combined. The mixture will bubble and foam, so be cautious.
- Step 7: Pour the hot peanut brittle onto the prepared baking sheet. Spread it evenly to a thin layer, approximately ¼ inch thick, using a silicone spatula. Work fast as the brittle hardens quickly.
- Step 8: Let the brittle cool completely at room temperature. Once hardened, peel off the parchment paper and break the brittle into bite-sized pieces. Serve immediately or store as desired.
Tips & Variations
- Use salted peanuts to enhance the flavor, or try unsalted and add a pinch of sea salt on top before cooling for a sweet-salty twist.
- If you don’t have a candy thermometer, test the syrup by dropping a bit into cold water—at the hard crack stage, it will snap easily.
- For added texture, mix in chopped almonds or cashews along with the peanuts.
- Be sure to stir gently and avoid stirring too much during the initial boiling phase to prevent crystallization.
Storage
Store peanut brittle in an airtight container at room temperature to keep it crisp. It will remain fresh for up to 2 weeks. Avoid storing in humid areas as moisture can cause brittleness to become sticky. No reheating is necessary; simply enjoy it as is.

FAQs
Can I use raw peanuts instead of roasted?
It’s best to use dry roasted peanuts for the classic flavor and crunch. Using raw peanuts may result in a less roasted taste and different texture.
What if my brittle turns out sticky or soft?
Sticky brittle usually means the syrup didn’t reach the hard crack stage. Use a candy thermometer for accuracy, or test the syrup by dropping a small amount into cold water before removing from heat.
