Vanilla Bean Peanut Brittle

Vanilla Bean Peanut Brittle

setting up on my silpat


Make sure you let the brittle cool at least thirty minutes before trying to break it into pieces.

There is a microwave peanut brittle recipe that I got from Taste of Home magazine years ago. Over time, I have changed many of the measurements and timing in order to suit both my tastes and my microwave oven wattage. This Christmas, I believe I made the best batch yet. I used a scant half cup of corn syrup (instead of a heaping half cup) and vanilla beans instead of vanilla extract. (I tried the vanilla beans because alcohol burns off as it boils, and the vanilla extract in the original recipe boils for five minutes). The result? Using a scant half cup of corn syrup makes this brittle extra crisp. Plus, the vanilla beans give this brittle an incredible scent and delicious flavor.

Prep time
Cook time
Total time
Serves: 8-12
  • 1 cup white sugar
  • ½ (scant) cup light corn syrup
  • ¼ teaspoon salt
  • 2 Tablespoons butter
  • 2 vanilla beans, scraped
  • 1 & ½ cups honey roasted peanuts
  • 1 teaspoon baking soda
  1. In a large glass bowl, combine sugar, corn syrup, and salt. Cook in microwave for six minutes on 80% power.
  2. Stir in butter, vanilla beans, and honey roasted peanuts. Cook for five more minutes on 80% power.
  3. Stir in baking soda until foamy.*
  4. Quickly pour onto a cookie sheet lined with silpat or parchment paper.** Using a silicone spatula, spread mixture to all sides of pan. Work quickly, as the brittle sets fast.
  5. Let cool on counter thirty minutes before breaking into pieces. Store in a loosely covered container to maintain crispness.
*The mixture gets VERY hot and bubbly. Use an oven mitt when handling the bowl. **Make sure you use silpat or parchment paper. Waxed paper will stick like crazy to the brittle and the candy will be ruined. ***This recipe is for a 1150 watt oven. Most microwaves are stronger, so you will need to cook at lower power. -For a 1200 watt microwave, cook at 70% power, keeping cooking times the same. ****Anything left in the bowl after pouring onto the parchment paper will be very hard to remove, so immediately soak the bowl in HOT water to unstick any leftover brittle.
