In case you couldn’t tell, I’m a total sucker for Christmas cookies. And cheesecakes. And brownies. Ok, maybe I have a sweet tooth. Of all the delicious desserts out there, I’ve grown particularly fond of the combination of salty and sweet. Common sense suggests that salt shouldn’t pair well with a sweet dessert…but common sense is just wrong when it comes to this Peanut Brittle recipe! This treat is the perfect way to round out that Christmas cookie platter or even to pack in tins and give to the neighbors, teachers, postal workers, your favorite bloggers, etc. After all, who can turn down a delicious homemade peanut brittle recipe…especially when it’s mixed with Peanut M&Ms?!

As a kid, I always remember my mom saying that peanut brittle was her favorite childhood dessert. I’d save up my allowance every Christmas (and maybe “borrow” some quarters and dimes from my sister) to get my mother a box of peanut brittle for Christmas. I didn’t particularly enjoy peanut brittle back then, but oh how times have changed! Now I understand the addicting deliciousness of those pieces of peanut brittle hiding in a cookie tin in the kitchen. And this version is even tastier thanks to the colorful addition of Peanut M&Ms.I debated what color M&Ms to use, but in the end, I decided on the traditional color mix. You could certainly use the red-and-green mixed M&Ms if you’re making this peanut brittle recipe for gifts or a holiday party.

I’m not much for television commercials, and I usually just fast forward through them on the DVR (unless we’re talking Super Bowl commercials…then that’s a whole different story!). But I really enjoy the M&M commercials. You know, the ones where Red is always getting into some kind of trouble. I particularly loved the recent one with Red singing “I Would Do Anything For Love.”“Happy thoughts…happy thoughts…” So I give credit to the folks at Mars for coming up with commercials that actually make me want to stop and watch them!

If you’ve never made a peanut brittle recipe before, then you’re in for a treat…pun intended! Peanut brittle is incredibly easy to make, although it does require a candy thermometer to make sure the mixture reaches 300°F. (And since melted sugar is incredibly hot, make sure to use extra caution when pouring the mixture into the sheet pan.) Other than those simple little tips, just let the mixture cool for 30-45 minutes and you’re done!
