It tastes good,But I had a hard time with it. I think maybe it should be whipped before adding the walnuts. I just don`t know. I did work fast.But it just seemed to harden to fast! Or even skip the whipping part!!!!!!! You may laugh at me but I buttered an other cookie sheet and put it on top then stepped on it using my weight to spread it out. There was no way I could have stretched it out.!!

I had to opposite problem! Mine didn't get cooked enough! After cooling, the brittle was soft and chewy. So I re-cooked the concoction in the microwave in small batches for about 3 minutes more and poured on my buttered sheet pan and then it cooled to a nice crunchy brittle. SO - a few points to consider, microwaves cook at different speeds and temps. I would highly recommend using a candy thermometer with this recipe because it needs to get to the hard crack stage. The mixture should be lightly browned, frothy and bubbly and it should sizzle a bit when poured on the cookie sheet. That's how you'll know it's been cooked enough. This makes a wonderful, delicious, tasty and crunchy brittle. As long as you make sure to cook it enough - you'll be so happy with the results!
