Key Lime Pie Marshmallow Treats are loaded with graham cracker crumbs, lime zest, coconut and Campfire® Marshmallows then drenched in a rich chocolate coating.

We just got home from Florida, approximately 4 hours and 32 minutes ago. And we drove, because what better way to test your relationship than to travel to Florida in a car for 17 hours and 56 minutes with a teething 6 month old? There is no better way. Trust me.

Elle was such a trooper, and although I cued the dramatics as soon as I started this post, things were pretty uneventful. Well, except for the ginormous accident aftermath we saw 5 minutes into our voyage back to Ohio. It basically had me breathing in and out of a Chick-fil-A bag and demanding that we just stay in Florida – forever.

We stayed on Gasparilla Island, which is pretty much my favorite place. After seeing my Instagram photos and reading this post, I’ve received a few emails from readers asking about this gorgeous vacation spot, so I’ll definitely fill you in on all the details in the coming weeks.

Speaking of Florida, Key West was my inspiration for these Chocolate-Dipped Key Lime Pie Marshmallow Treats. Although I’ve never stepped foot on the island, I’ve heard amazing things about the place from friends and family. I’ve also been told that the island serves up Chocolate-Dipped Key Lime Pie on a stick. I’ve convinced myself that this has to be the best dessert in the history of desserts. A) It’s Key Lime Pie B) It’s on a stick. And everything is better on a stick. C) Because it’s dipped in chocolate.

I had a desperate craving for marshmallow treats, and then I got to thinking about that Key Lime Pie dipped in chocolate. I thought what better way to kick them a notch than to load them with lime zest and drench them in chocolate? I’m fairly certain they’ll immediately transport you to a tropical climate – even if you’re sitting on your brother’s couch in Ohio after a gazillion hour roadtrip <--- that'd be me!

Mini marshmallows have always been my favorite. For cocoa, for marshmallow treats, for tossing into my gob at break-neck speed. There’s just something so adorable, so snackable, about baby marshmallows. In my opinion, Campfire® Mini Marshmallows are the best tasting marshmallows on the market – they’re super soft, fluffy and oh, so delicious.

As you may remember from my Salted Caramel S’mores, I’m partnering with Emily from Jelly Toast and Campfire® Marshmallows over the next year. You’ll see more recipes from us, and hopefully even more exciting stuff as the year goes on.

Be sure to check out Emily’s post for Marshmallow Strawberry Shortcake – I can’t handle the gorgeousness! Please don’t miss it.

We even created a Marshmallow Madness Pin Board where we’ll pinning all of our favorite marshmallow recipes from our favorite food sites.

    My boyfriend and I have been driving to Kansas from California for Christmas these past two years. The ride there is so much fun for us. It’s the ride back, especially that last stretch that kills us! Food, more specifically rice krispy treats, definitely makes our car trips much better. This is such a creative recipe. I’ll have to make it for our next road trip.

  3. Jamie says:

    I don’t envy your long car ride at all! I get restless riding in or driving a car for longer than 2 1/2 – 3 hours. I’m loving the chocolate dipped key lime pie treats though! They look delicious!!!

  4. Allison says:

  6. Jocelyn @BruCrew Life says:

    Driving long distances definitely does test all the relationships in the vehicle. We usually drive to FL too because 5 airline tickets is ridiculous!!! I have actually had that chocolate dipped Key Lime pie in Key West…it is crazy good!!! So I know that I will be in love with these awesome rice krispie treats with all the same goodness packed into them.

  8. Tom @ Raise Your Garden says:
