How to Make Peanut Brittle In the Microwave
First, you need a 1100 watt microwave to have success with this recipe. If your microwave is not 1100 watts I can’t guarantee the results. So if your microwave is not 1100 watts go out and buy a new microwave. It will be worth it. Just kidding. Sort of. 🙂
In a 1.5 quart baking dish combine raw peanuts, sugar and light corn syrup. So many recipes out there say to use regular peanuts. Don’t do it. You need raw peanuts that will cook naturally as you make this recipe. You can find raw peanuts with skins in the produce section of your grocery store. They’re not with all the other peanuts. Why? Why!
Microwave at 70% power for 4 minutes and 25 seconds.
Stir like crazy.
Put it back in the microwave at 70% power and microwave for another four minutes.
Stir in the butter and vanilla.
Microwave for the last time at 70% power for two minutes.
Immediately add the baking soda and stir until the peanut brittle is foamy and light.
Pour onto a greased baking sheet. The brittle will naturally spread to about 1/4 inch thickness.
Let cool and break apart.
How long does it take peanut brittle to cool?
It takes about 30 to 45 minutes to completely cool. Unless you’re like me and live in a drafty old farmhouse – you can cut that cooling time in half. 😉
Do I need a candy thermometer to make this recipe?
No. You can make this easy peanut brittle recipe without a candy thermometer because of the exact baking times in the microwave using a 1100 watt microwave at 70% heat.
How long does Peanut Brittle last?
You can store in an airtight container on the counter for up to 1 week or until you find it starts to taste stale.
I hope you enjoy this old fashioned homemade recipe that’s been adapted to the microwave! You get the same amazing results without the time and hassle of a vintage recipe. That’s winning in my book!
