What You’ll Need

Ingredients:

  • 1 cup granulated sugar
  • 1/2 cup light corn syrup
  • 1 cup roasted salted peanuts
  • 1 tablespoon unsalted butter
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda

Tools:

  • Microwave-safe glass bowl (e.g., Pyrex)
  • Silicone spatula or wooden spoon
  • Measuring cups and spoons
  • Parchment paper or a silicone baking mat
  • Heat-resistant gloves or oven mitts

Pro Tips for Perfect Microwave Peanut Brittle

  1. Use a Microwave-Safe Bowl: A sturdy glass bowl is crucial, as the candy mixture will get extremely hot.
  2. Work Quickly: Once you stir in the baking soda, the mixture foams up and sets fast. Have your parchment paper ready before you start.
  3. Measure Everything in Advance: Candy-making is all about timing, so measure out your ingredients before microwaving to avoid delays.
  4. Be Careful with Heat: The sugar mixture will be very hot, so use oven mitts when handling the bowl.
  5. Add a Pinch of Salt: If your peanuts are unsalted, add a pinch of salt to balance the sweetness of the brittle.

Substitutions and Variations

  • Peanuts: Swap with almonds, cashews, or a nut mix for a fun twist.
  • Butter: Use margarine or coconut oil for a dairy-free version.
  • Corn Syrup: Replace with honey or maple syrup, though the texture might vary slightly.
  • Flavor: Add a pinch of cinnamon or a splash of rum extract for extra flavor.

Make Ahead Tips

  • Peanut brittle keeps for weeks, so feel free to make it in advance. Store it in an airtight container at room temperature to maintain its crisp texture.

Instructions: How to Make Microwave Peanut Brittle

Step 1: Combine Sugar and Corn Syrup

In a microwave-safe glass bowl, combine 1 cup granulated sugar and 1/2 cup light corn syrup. Mix until the sugar is moistened.

Step 2: Microwave the Mixture

Microwave the bowl on high for 3 ½ to 4 minutes, or until the mixture is bubbly and lightly golden.

Step 3: Add Peanuts and Butter

Carefully remove the bowl from the microwave (use oven mitts!) and stir in 1 cup of roasted peanuts and 1 tablespoon of unsalted butter. Return to the microwave and heat for another 1 to 1 ½ minutes.

Step 4: Stir in Vanilla and Baking Soda

Remove the bowl again and quickly stir in 1 teaspoon of vanilla extract and 1 teaspoon of baking soda. The mixture will foam up—this creates the light, airy texture of the brittle!

Step 5: Spread onto Parchment Paper

Immediately pour the foamy mixture onto a sheet of parchment paper or a silicone baking mat. Use the spatula to spread it out into a thin layer. Let it cool completely (about 30 minutes).

Step 6: Break into Pieces

Once the brittle is completely cool and hardened, break it into rustic pieces and serve!

Leftovers and Storage Tips

  • Storage: Store the brittle in an airtight container at room temperature for up to 2-3 weeks. Avoid refrigerating, as moisture can make it sticky.
  • Gifting Idea: Wrap pieces in wax paper or cellophane and pack them in a decorative tin for a thoughtful gift.
