It is so unnecessary to grease a cookie sheet! Just roll out 2 foot of aluminium foil on a counter. Nothing needed on the foil. After the brittle is cooled Just pull the brittle off or pull the foil to the edge of counter downward and bend the brittle upward and it breaks off. I like to transfer the foil and brittle to a cooler spot on counter where cooler so cools faster.

I have used the original recipe for many years with great success. I also make a few batches with pecans!! I had to purchase a new microwave last year and I was happy it was a 1200 watt... guess what... that is toooo hot for this recipe. I could not find the right time adjustment!! My sister successfully found the right time: mix, cook 3 mins., stir, cook 3 mins; add final ingredients and cook 2. Perfect again. My family is so happy!!!

My husband loves it with pecans instead of peanuts, too.

What type of utensil is best for stirring, and a word of warning. DO NOT attempt to use your finger to clean the utensil you are stirring with. OWIIIEEEEEE!!!

I think foolproof should be tempered with the comment you may need to adjust to your microwave's particular power/wattage. The first batch I made was overcooked at 8 minutes total The way I read the recipe it is a total of 10 minutes cooking time. At just over 8 minutes my first batch was moderately burnt. Second batch at about 7 total was about right. I lost my regular recipe and the ingredient proportions on this seemed the same, so it's a great basic recipe just experiment with the time. If you like coconut a little toasted coconut is a nice touch at the end.

Outstanding and simple! Like other reviewers suggested, I adjusted the cooking time based on the power of my microwave. Stir at four minites and add one minute thereafter until it bubbles and gets a bit of color, but don't go longer than 8 minutes or it might burn the peanuts. I was interrupted by a phone call in the middle of making this and forgot to add the butter. It tasted great without it, but your results may vary. Merry Christmas and happy holidays to all!

Turned out perfect, does anyone know if you double it how long to adjust the times for ?? I also made it with macadamia nuts, can you say " Awesome" !!

This is a great recipe and can be found in various forms on lots of sites. I have cooked for seven and a half or even seven minutes, total, with my eight year old microwave and had successful results. I cook the sugar/corn syrup mix for three minutes, add in (jarred) roasted, lightly salted nuts, cook for two and a half minutes, then add the butter and vanilla, mixing well after each time out of the oven. Then, after the last two to two and a half minutes is up, quickly add in the baking soda, beating while everything foams. Having all your ingredients ready is key while I find the pre-heating of your pan doesn't really make a difference to the "spreadability" of the hot brittle. Use Pam or similar for coating your pan, then put aluminum foil down and spray again. And, spray your spoon used for stirring. I use a pan specifically made for the micro and heavily spray that, also. And, I use the dark Karo syrup which doesn't affect the taste, but makes a lovely colored brittle!

You've got to try this recipe!! It never fails even with my old microwave. Even when I put the butter in too soon! It's the perfect peanut brittle. I even shell my own peanuts because my grandchildren are allergic to tree nuts.

I bought one of those LARGE 2 quart Pyrex mixing pitchers with the handles. Very easy to handle the HOT glass! The timing depends on your bowl, if everything is room temperature, if your soda is new, lots of variables. But the end result is great, just need to test it out with your microwave. Trial and error. Just put messing bowl in sink and run the HOT water into it and let sit. It melts right off.

This is like the recipe I got from my 89 year old Aunt. Everyone loves it. Her hint is you need to buy NEW soda or it could be a flop!

To clean your bowls and any utensils you use. Boil a pot of water. When you have poured out your brittle pour the boiling hot water on your utensils let it sit a few minutes the hardened sugar comes right off. I spread my brittle with a spatula that I spray with pam.

This a great recipe. The only thing I suggest is stir between one and a half minutes, it keeps the sugar from burning. I only need 4 minutes for the whole recipe. I have gotten several requests for my home made microwave peanut brittle. If you like cashews they are great as brittle as well.

I tried last night and it turned out chewy not brittle. The only thing I did differently was double the recipe. So what do you think was the problem? Thanks,

Cooked for 6 minutes. Came out great. Also preheat. Cookie sheet. Now how do you clean the bowl? ?
