Okay I’ve been healthified the last two weeks, but now it’s time to dive straight into downright indulgent peanut butter craziness.  Ryan is a total peanut butter addict – he goes through massive amounts in a week, and we’ve always got extra stocked up for baking or related emergencies.  I like to say he eats peanut butter every morning with a side of banana.  Well, let’s just say that I used up all the peanut butter in the house to make these rise krispie treats last weekend.  That’s a lot of peanut butter!  These aren’t for the faint of heart but OMG they’re amazing.  And thankfully this is one case when pictures actually come close to doing them justice…

When I saw these on Your Cup of Cake‘s blog, I immediately added them to my recipe queue.  Believe it or not I’ve never made rice krispie treats, and I thought that was something I should probably do if I wanted to go around calling myself a baker of sorts.  I’ve never really been drawn to the normal variety – I’m not a huge fan of marshmallows and whenever there were brownies also lined up at bake sales, I always bee-lined for those. But this is not your average rice krispie treat.  Yes, it starts with the basics of rice krispie cereal and marshmallows, but there’s also a boatload of peanut butter, a layer of peanut butter fudge mixed with mini Reese’s peanut butter cups, and a topping of creamy chocolate peanut butter ganache.  They’re the mother of all rice krispie treats in my opinioin, and they disappeared off the tray at my brother’s pool party last weekend quicker than anything else on the dessert table!

The only downside of these treats is the execution for this particular recipe is a bit more labor intensive than your average rice krispie treat.  I think one of the reasons rice krispie treats are so popular is because they’re so easy to put together – it’s just mixing together some rice krispies and melted mashmallows, and you don’t even need to turn the oven on.  But these particular krispies involve 3 layers – one layer of peanut butter fudge with mini peanut butter cups mixed in sandwiched between two layers of regular peanut butter rice krispie treats.  And then of course you have to top the whole thing with the chocolate peanut butter ganache.  So it’s a few more steps than you might be used to, but SOO worth it!  The final result is almost unrecognizable as a rice krispie treat, but you still get that wonderful slight crunch from the cereal that will bring back all your memories of rice krispie treats growing up.  (Unless of course you were like me and never really ate them…)  Either way I think I’ve given you more than enough reasons to make these, especially if you have a peanut butter fanatic in your family like I do!

    I’ve had these pinned for a while and will finally be making them this weekend, but I’m thinking about using mini rolo candies and pressing crushed pretzels into the ganache on top for a Take 5 kind of combination. In any case, yum!

    We’re moving in 48 hours, and I wanted to use up our half-boxes of cereal and make some snacks for eating on the go. I used your recipe from the Rice Krispie layer, and finished the last of our Cap’n Crunch Peanut Butter Crunch cereal, roughly crushing the cereal with a rolling pin. This stuff was an instant hit! Everybody’s new favorite. Move over, Rice Krispies.
