The bottom of my plastic bowl melted through! Make sure to use a glass bowl!!

Need to adjust cooking time. Mine burnt after 6 mins total in a 1,000 watt microwave. Maybe 4 1 min would work better. Will try again, as this is such a simple recipe, and would like to make it work! I was able to get it out before it was too burnt, and think I will crush it up and use it in a topping.

For those of you who used cashews - were they raw or roasted or does it matter? I noticed starting out with raw peanuts in the recipe yields nicely crunchy cooked peanuts when it's done - so is it best to start with raw cashews so they don't get overly hard during the cooking process?

I absolutely LOVE this recipe. I have killed my peanut brittle the last two years... and I was devastated. I gave this recipe a try after ruining one batch of brittle this year. I will NEVER use a different recipe! This one is perfect!

I have changed microwaves and my new one is higher wattage; therefore I have been searching for the cooking time for 1000 watts or higher. Thanks for your cooking results on the time variables as this is key in microwave peanut brittle. I first burned it, then under cooked so now maybe I can get it right with those who have previously failed and tried again!

Tried this for the first time after seeing the recipe in The Houston Chronicle. The Chronicle recipe was exactly the same, except that it said for an 1100 watt microwave, use power level 8. Even then, after the first slightly overcooked batch, I reduced each cooking interval by 30 seconds and had better results.

Awesome recipe!! I have a 1000 watt microwave, so I cooked the first four ingredients for 6 minutes (not 8) & stirred after 3 minutes. I also added just a bit more baking soda & lined my baking sheet with aluminum foil instead of using butter (no need for extra fat - the foil just peels off after the candy cools). Thanks for the recipe!!

Had to try a couple of times. With my microwave it was 3 minutes, stir then 2 minutes butter then 1 minute and vanilla and baking soda. The idea of using foil on sheet also was a great idea

How easy is this? I am in awe. Yes to the 6 min/2min cook time. If you don't have raw peanuts, throw your spanish peanuts into the brew after 3. It's fun when you add the vanilla and the baking soda and the whole thing puffs up and goes caramel color and makes the whoosh sound! Proof that candy making is chemistry. It can be hard to spread thin but even if you don't get it microscopically thin it will taste good.

I have made this for about 15 years, however I only cook mine for 6 minutes (stir after 4 minutes). I then add the salt, butter and vanilla and cook for 2 more minutes. It is impossible to spread. I just pour it onto a buttered cookie sheet and let it harden.

Hi all. I've been using my microwave for brittle for more than 20 years with great success. Newbies should depend on their nose and eyes when first trying this! The syrup will begin to darken, and the peanuts will become very fragrant. Don't go by the timer or you'll likely burn it! Also, heat a buttered cookie sheet in the oven while you cook the brittle in the microwave. When it's ready, pop the pan from the oven to the stovetop and while it's hot, pour the candy mixture onto it. Don't spread it. Don't mess with it. Leave it alone! Walk Away! The candy will spread itself over the hot pan and still contain those little bubbles that make it light, airy, and crunchy. You'll be delighted!

Hilarious! The name needs to be changed from 10 Minute Never Fail Peanut Brittle to 8 Minute Never Fail Peanut Brittle... but mine was more like 7 minutes. (6 minutes for the first 4 ingredients then just one minute after the butter). I have a 1200 watt microwave so I could smell when it was done!

It would have been beneficial to know the wattage of the microwave where the brittle came out perfect after 10 minutes. I also had to cut my cooking time down to 6 minutes and probably could have stopped at 5.5 min. Everything else was great. Waiting for it to cool so we can eat it!

This recipe is so easy and tastes just as good, if not better, than any stove top peanut brittle I've had. I was stressing over my first attempt at peanut brittle but, when I found this recipe for the microwave, I was so relieved. Even more so when I tasted it! It's delicious and every bit as easy as it sounds! After reading the reviews, I did reduce the first part of the cooking time to 6 minutes and it came out perfectly.

Been making this recipe for over 25 years. Made an error with the baking soda first time. My friend that gave me the recipe was angry when my batch turned out better than hers. :-) The error was my using the orange Tupperware measuring spoons as they measured in rounded AND half measures. I grabbed the teaspoon and a half and was over-all more airy. I also put my vanilla in at the same time as the butter. The baking soda goes in last by itself. I work very quickly once the soda is in and pour immediately onto the buttered cookie sheet. I DO NOT SPREAD as that takes the air out of the finished product. Try it and see what you think. I think you will like it much better! SB.
PS. This is the original recipe and all measurements and ingredients are correct! Only the time may vary according to your individual microwave. Over the years I had to lessen the time due to having a carrousel . It would cook hotter and quicker! GOOD LUCK!!
