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

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!!

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.

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!

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!

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?

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.

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

This recipe is amazing!!

I tried microwaving this for a shorter amount of time as suggested because my microwave is pretty powerful and it turned out much too sticky. I made it again at 6 minutes, 2 minutes and it turned out AMAZING!!! I have made probably six batches since then using this recipe and I highly recommend it! If you don't like the way it turns out, it most likely has to do with the microwave time. I am interested in trying out the extra baking soda next time. What kind of change does this create?

This recipe is great. I followed the advice of previous posts and lowered the time to 6 minutes plus 2 minutes, it turned out perfect. Definitely a keeper for a fulltime RV'ing couple.

My sister in law told me about this..It is absolutely fantastic! We will have peanut brittle all year now.. Will try the 6 minute thing tho.. Got a mighty microwave.

Cant wait to try this recipe! LOVE brittle but often time consuming! I use the microwave in ALL my chocolate classes. Love the efficiency. Whenever I try a new recipe I do however start in shorter time spurts to avoind burning my first batch. Thanks for sharing!!

I made peanut brittle the old fashioned way 2 times this year and both times it turned out too sticky (it would have pulled out your fillings). Someone said it was too humid. Then I found this recipe and it turned out perfect!!! Way to go!! Will keep on using this recipe each year from now on!!!!

Totally burned and tasted gross. Have to start all over.

I have been making this for several years and everyone loves it. I have had to adjust the time to under 6 minutes. Use 1 1/2 tsp. baking soda for better brittle. Also, this year I have spread it on a buttered silicone mat. Works Great!

First time I made this and it turned out wonderful. I will be using this recipe again. So easy. I will try the extra baking soda that Kim suggested.

I've used a recipe similar to this for years, and agree on bumping up the baking soda to 1 1/2 tsp. Cooking time is based on your microwave - just keep an eye on it the first couple times you make it.

For a twist, replace the peanuts with cashews and add a tsp. of nutmeg and cinnamon.
