People rave about this, and it is so simple. To help with cleanup, soak the measuring cup or bowl in very hot soapy water. Easy! DO NOT spread the peanut brittle--just tip the cookie sheet back and forth. You do not want to break the "bubbles" made by the baking soda. That is what makes it "tender." The thinner the better, so I heat my cookie sheet in a warm oven so the candy spreads more quickly.


This is a great recipe, fast, fun, easy and delicious. The first time I made it I followed the cooking time exactly and it burned. Next time I cut the first cooking time to 3.5 minutes the second to 3 minutes and the last cooking time to 1 minute, and it turned out perfect. My microwave is 1000 watts. This has become a family favorite.


This really was delicious. The only thing is that the baking soda needs to be stirred in very quickly. Then the mixture needs to be poured out AS SOON AS the baking soda is stirred in. The directions "stir until light and foamy" are a little misleading. It doesn't become light and foamy as you stir. . . it becomes less light and foamy. It was hard to pour out, but ended tasting very good. *update: I have now made this recipe numerous times. At first I gave it 4 stars; however, if you follow the hint I gave above, the recipe is 5 stars. The Peanut Brittle is fantastic. My grandmother is THE candy-maker, and my mom says that she cannot tell the difference between mine and my grandmother's (she slaves away all day on her's). Also, this recipe is delicious topped with chocolate. All you have to do is put a layer of semi-sweet chocolate chips (or whatever kind of chocolate you prefer) on top of the brittle as soon as you pour the mixture out onto the cookie sheet. The chocolate will start to melt; simply spread the chocolate over the peanut brittle with a spatula. Absolutely delish!
