Ingredients

• 1 cup granulated sugar
• 0.5 cup light corn syrup
• 0.125 teaspoon salt
• 1 cup unsalted peanuts
• 1 tablespoon unsalted butter
• 1 teaspoon vanilla extract
• 1 teaspoon baking soda

Directions

Step 1

Prepare a baking sheet by lining it with parchment paper or a silicone baking mat; set aside.

Step 2

In a large microwave-safe glass bowl, combine the granulated sugar, light corn syrup, and salt. Stir until well mixed.

Step 3

Microwave the sugar mixture on high for 4 minutes. Carefully remove the bowl from the microwave (it will be very hot).

Step 4

Stir in the unsalted peanuts, ensuring they are fully coated in the hot syrup.

Step 5

Microwave the mixture on high for an additional 3 to 4 minutes, or until the mixture turns a golden brown caramel color.

Step 6

Remove the bowl from the microwave and immediately stir in the unsalted butter and vanilla extract. Mix until fully combined.

Step 7

Quickly stir in the baking soda. The mixture will foam up as the baking soda reacts with the caramel. Stir until evenly distributed.

Step 8

Immediately pour the peanut brittle mixture onto the prepared baking sheet. Using a spatula, spread it out into an even layer.

Step 9

Allow the peanut brittle to cool completely at room temperature, about 30 minutes.

Step 10

Once cooled and hardened, break the brittle into pieces and serve or store in an airtight container for up to two weeks.
