Tips and Tricks

  • The bowl gets very hot. You’ll see I recommend using hot pads. Learn from my mistake and always use them.
  • I use dry roasted, lightly salted peanuts (no skins). You can also try switching it up and make this Cashew Brittle too.
  • Finally, clean up. The brittle hardens in the glass bowl very quickly. Fill with HOT water and allow to soak until you can scrub it off.

Make Peanut Brittle on the Stove Top

Yes, you can also make this on the stove top if you prefer.

  1. Line your baking sheet with parchment paper like above.
  2. Using a heavy 2 quart saucepan over high heat, bring to a boil the sugar, corn syrup, and add 1/4 cup water.
  3. Stir until sugar is dissolved and mixture is boiling. Reduce heat to medium.
  4. Stir in peanuts. Set a candy thermometer in place, and continue cooking until temperature reaches 300 degrees F (or until a small amount of mixture dropped into very cold water separates into hard and brittle threads.
  5. Remove from heat and immediately stir in butter, vanilla, and baking soda. Pour onto baking sheet and spread to desired thickness. Break into pieces when completely cooled.

Comments & Reviews

  1. Aimee I was just wondering, you say power level 7 on your 1500 watt microwave. Would that be the same for a 1200 watt?

    1. I live in the South, humidity makes a huge difference with any brittles. Ideally this peanut brittle works best on the lowest day of humidity. Don’t try if it is raining or recently rained, it will be “sticky” and chewy not “crisp”. I was raised in the West, never had this problem, even experienced cooks have to learn about weather and how it effects everything.

  2. I have an older microwave and I am not sure of the wattage. It also doesn’t have the option of setting a power level. What would you suggest for timing?

    1. I was making peanut brittle and dropped my eyeglasses in the boiler. How can I get the sticky hardened candy off my glasses?

  3. Great idea! Peanut Brittle is something I’ve never bothered to try making, assuming that it would be too much effort. But now I have no excuse!
