Key Lime Pie Puppy Chow Muddy Buddies

Is it called puppy chow or muddy buddies?

OK, let’s talk about this Key Lime Pie Puppy Chow Recipe. Or do you call them Muddy Buddies? You know, the cereal squares coated in melted chocolate and peanut butter, then shaken all up with powdered sugar. Or, as I like to call them – Crack!

Honestly, I never know what to call this stuff. I mean, I suppose Muddy Buddies work when you use dark or milk chocolate because they do have kind of a muddy look about them. But really, the name isn’t all that appealing. And then when you make them out of white chocolate, it totally doesn’t work.

I have a Chai Tea White Chocolate Puppy Chow recipe that I originally called “Snow Buddies.” For that flavor, it works. Key Lime? Snow? I don’t think so.

And then there is the ever-popular Puppy Chow recipe. Except maybe it isn’t so popular. I brought some to a mom’s group, said it was Puppy Chow, and somebody asked me if it was for people to eat. Disclaimer: this was before she tasted it. #fail

So there is also just Chex Mix, but to me, that conjures up images of pretzels and peanuts and something salty for snacking while watching football. And you know, trademarks and all. Cereal Treats – those are the bars made with melted marshmallows. Not gonna work.

Oh gosh, I’m done. I went with Key Lime Pie Muddy Buddies. Then changed it to puppy chow. Oh gosh. Maybe I should have gone with Key Lime Crack. Because for you citrus lovers out there – seriously addictive, people! And the fact that it takes about five minutes to make. Umm, yeah…

How do you make puppy chow that tastes like Key Lime Pie?

The Key Lime Pie puppy chow recipe is super duper easy to make.


  • From the traditional Muddy Buddy recipe, I swapped out the milk or semisweet chocolate chips and peanut butter for white chocolate chips and butter.
  • Then I added some lime juice and zest (don’t get all up on me – I know they aren’t technically key limes. Sorry.).
  • As for the cereal part, I swapped some of the Chex for graham cracker pieces. This gives it a bit of “crust”.
  • Melt the chips and stuff, stir together with the cereal, toss in a big old Ziploc bag with powdered sugar and let the 3-year old shake it up. Definitely, a fun snack to make with the kids.

One disclaimer, I often find that white chocolate melts a little weird, Between that and the lime juice, it looks a little thick when you melt it. Just pour it over the cereal and toss around a bit. It’ll get coated enough to make it sticky for the powdered sugar to cling to all the pieces in a sweet and yummy coating.

How do you make muddy buddies gluten free?

Want to make this key lime pie puppy chow recipe gluten free? Instead of the cup of graham cracker pieces, just use all Chex (I think even a cup of the Cinnamon Chex would be awesome for a little graham-cracker-ish-ness). Or simpler yet, grab some gluten free graham crackers. Easy peasy!

All the flavor of the classic Key Lime Pie in a sweet and yummy snack mix that takes only minutes to make! Make sure you double the recipe to feed the whole gang!
Prep: 6 mins
Total: 6 mins
Servings: 14


  • 1 cup powdered sugar
  • 4 cups Chex cereal your favorite variety
  • 1 cup graham crackers broken into pieces similar in size to the Chex (see Note for a gluten free option)
  • 1 1/2 cups white chocolate chips
  • 2 Tablespoons unsalted butter
  • 1 teaspoon vanilla
  • 2 teaspoons lime zest
  • 1 Tablespoon fresh lime juice


  • Place powdered sugar in a large zip top plastic bag and set aside.
  • Gently toss together the Chex and graham cracker pieces in a large bowl.
  • Combine the white chocolate chips, butter, vanilla, lime zest and lime juice in a bowl and gently melt in the microwave or over a double boiler. If doing it in the microwave, use 50% power and stir every 15-30 second until melted. It may look slightly thick and clumpy.
  • Pour chocolate mixture over the Chex mixture and gently stir and toss until fully coated, breaking up any large clumps that may form.
  • Transfer the cereal mixture to the plastic bag with the powdered sugar seal and toss until fully coated.
  • Pour out onto a sheet pan lined with a nonstick baking mat or wax paper and allow to cool and harden.
  • Store in an airtight container.


To make this gluten free, use another 1 cup Chex (perhaps try the Cinnamon Sugar Chex), or gluten free graham crackers.

    I was so excited for this but my chocolate seized and i followed directions to the T. Ugh. I was hoping it would be salvageable but it ended up tasting off because of the chocolate. ?

    1. White chocolate is definitely temperamental. I’m sorry it didn’t work out for you. Not sure what type of white chocolate you used, but candy coating chocolate or almond bark sometimes work better than chocolate chips or the bars you get in the grocery store.

    1. Brianne Cupcakes & Kale Chips

      Ashley, I’m sorry you’re having difficulty with the white chocolate. All chocolate is very sensitive to heat and other liquids. If the chocolate gets too hot, it will seize up, and if you get even a drop of water in bowl with the melted chocolate, it will seize up. If you’re melting the chocolate on a stove top, it might help to place the chips in a metal bowl and place it over the top of a saucepan with simmering water. You don’t need much water in the pan at all… you don’t want the bottom of the bowl to touch the surface of the water.
      If you’re melting it in the microwave, use 50% power and stir every 15-30 seconds, just until the chocolate melts.

    LOVE LOVE LOVE anything citrus and can’t wait to try these!!! Just a thought…. for the “graham-y” part….how about throwing some graham cracker crumbs into the mix instead of the pieces???

  3. I love puppy chow! It’s so addictive. I make all different kinds and making them fruity is a great idea. I wondered if fruit juice and zest could be added. Most orange/lime/lemon versions I see use cake mix or something weird so I love this!

  4. I have had Muddy Buddies recipes “pinned” for ever & still have not made any! Since Key Lime is the hubs’ absolute favorite dessert, I must try your recipe. Thanks!

  5. Lesa @ Edesia's Notebook

    Yummy! I grew up calling these Puppy Chow, but I think Muddy Buddies is more common. That’s what Chex calls them. Your key lime version sounds really good. Can’t wait to try it!
