Easy Key Lime Pie Puppy Chow Recipe

The no-bake snack mix with a name that confuses people, but a taste that is incredibly addictive! The classic Chex snack mix gets a citrusy makeover. Whip up a batch in minutes for your next party and the bowl will be empty in no time. It is definitely, a fun snack to make with the kids.

 

This is a departure from the traditional Muddy Buddy recipe. First, it swaps out the milk or semisweet chocolate chips and peanut butter for white chocolate chips and butter. Then lime juice and zest add that fresh and tart flavor.

As for the cereal part, swap some of the Chex for graham cracker pieces to give it a bit of “crust” since it is a nod to Key Lime Pie, and you can’t have pie without crust!

Just try to keep your hands out of the bowl!

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 – my kryptonite!

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. And when you make them with white chocolate, it totally doesn’t work.

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 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. Well, whatever you call it, for the citrus lovers out there – seriously addictive, people! And the fact that it takes about five minutes to make. Umm, yeah…

Ingredients

  • Powdered sugar: To give your Muddy Buddies a sweet coating.
  • Chex cereal: You can use your favorite variety, just be sure to use rice or corn to make it gluten free.
  • Graham crackers: Break them into pieces similar in size to the Chex. If you are gluten free you can use additional Rice or Corn Chex, Cinnamon Chex, or buy or make your own Gluten Free Graham Crackers.
  • White chocolate chips: Or white coating chocolate. Note that Ghirardelli white chocolate chips are NOT gluten free.
  • Unsalted butter
  • Vanilla extract
  • Lime zest: Use a zester to zest the lime before you juice it.
  • Lime juice: Juice that lime after you zest it because fresh lime juice give it the best flavor.

How to Make Key Lime Pie Muddy Buddies

The puppy chow recipe is super duper easy to make.

Get things ready: Place powdered sugar in a large zip top plastic bag and set it aside. Line a sheet pan with a nonstick baking mat or wax paper. Break up the graham crackers and gently toss together the Chex and graham cracker pieces in a large bowl.

Melt the chocolate: 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 seconds until melted. Note that because of the lime juice, it may be a little thick.

Coat the cereal: Pour the chocolate mixture over the Chex mixture and gently stir and toss until fully coated., breaking up any large clumps of chocolate and cereal that may form. Because the white chocolate gets thick, it may not coat as smooth an evenly as with milk or semisweet chocolate, but it’ll coat enough for the sugar to stick.

Toss in sugar and cool: Transfer the cereal mixture to the plastic bag with the powdered sugar seal and toss until fully coated.

Cool and enjoy: Pour out onto a sheet pan lined and allow to cool and harden.

Storing Puppy Chow

Key Lime Pie Muddy Buddies can be stored at room temperature in an airtight container for up to a week.

Tips for Success

Make it gluten free: Be sure to use Rice Chex or Corn Chex. You can use gluten free graham crackers or just use additional Chex. Cinnamon Chex would give that hint of warm spice like graham crackers. Also be sure your white chocolate chips are gluten free because some brands such as Ghirardelli, are not.

Use one lime: You should only need one lime. Just be sure to zest it before you juice it.

Melt the chocolate with the lime juice: If you add the lime juice to the melted chocolate, it will seize immediately and won’t coat well.

Work quickly: Make sure you have the Chex and graham crackers ready before you melt the chocolate. Since it is thick, it starts to harden quickly. While it doesn’t have to coat the cereal perfect smoothly, you don’t want it to seize and form lots of big clumps right away.

Double it: If you are bringing Key Lime Pie Puppy Chow to a party, make sure you have plenty because it will disappear fast.

PLASTIC STORAGE BAGGIE HOLDER: As shown in the video, one of the best gadgets to make this simple snack even easier is this holder to hold the zip top bag open while you pour in the coated cereal pieces.

MICROPLANE: The best tool for zesting citrus, as well as finely grating chocolate, ginger, or parmesan cheese.

WAX PAPER: Make sure you line your baking sheet so the puppy chow doesn’t stick.

WHITE CHOCOLATE CHIPS: Nestle white chocolate chips are gluten free, if that is a concern for you.

    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!
