While I was at the grocery store the other day, I got a massive craving for chocolate milk. It legit came out of nowhere, but I immediately bought a carton of skim milk and a bottle of Hershey’s Dark Chocolate Syrup (because yessss) and went home and made myself a giant glass of chocolate milk. It was everything I wanted and more except that I felt seriously sick after drinking it. Probably because I haven’t had an entire XL size glass of milk in about 20 years. It also made me realize that I haven’t made a for real cup of hot cocoa in ages, which, when you consider that hot cocoa really is the best part of winter, is pretty sad. While I don’t think we’re going to get any more snow in Boston this season, I do know that we’re still stuck with weather in the 30s and 40s. So, I may just have to come home from work one evening this week and make myself a mug.

In the meantime, I’ll just eat my chocolate. Which is totally fine with me. Also, while I do enjoy a good hot chocolate from time to time, I much prefer Mexican hot chocolate and am pretty much in love with all things cinnamon. In fact, I often sprinkle a little cinnamon into my coffee grounds before brewing our morning coffee and mmm it makes it so much better. So, I obviously bought these new Cinnamon Pebbles the second I saw them on the grocery store shelf (p.s. cinnamon is SO a thing in the cereal world right now… I also just noticed Cinnamon Frosted Flakes the other day!) and knew I needed to combine them with chocolate ASAP. I did exactly that with these Mexican Chocolate Whoopie Pies with Cinnamon Pebbles and a delicious marshmallow buttercream.

I made my whoopie pies in a whoopie pie pan because I have one and don’t use it nearly enough. But if you don’t have one, it’s no problem at all! You can easily make whoopie pies on a parchment paper-lined cookie sheet, just like you would regular cookies. Into my batter went lots of cocoa powder, cinnamon, and some espresso powder, too. And don’t forget to fold in the Cinnamon Pebbles!

The frosting is also super easy to whip up. I was close to making my own marshmallow fluff because I hate buying the stuff, but you know… the container literally lists the same ingredients as what I put in my mixing bowl, so I took the easy way out here. No shame… I just wanted to get these whoopie pies into my mouth as soon as possible!

And done. I feel like this is one baked good that is seriously underrated and I have no idea why. Don’t get me wrong, I’ve had some not-so-great whoopie pies in my day, but I think the key is to really have a nice moist cake/cookie and enough filling to balance everything out. I think I had success here!

And yeah, those Cinnamon Pebbles. I’m a big Pebbles fan in general and love baking with Fruity Pebbles since they’re so fun, bright, and cheery. And remember Ice Cream Pebbles?? I wish those would come back! But I seriously hope Cinnamon Pebbles are around to stay because they are my new “dessert cereal” obsession. I don’t really eat sugary cereals for breakfast, but love stuff like this for a snack or dessert! Or, you know, incorporating into other desserts.

If you’re not on the chocolate/cinnamon AKA Mexican chocolate bus, I urge you to get on it. Cinnamon also has a crazy amount of antioxidants and health benefits, so that should make you feel even better about indulging in dessert. Not that you should ever feel bad about it. I’m all about balance in my diet and try to eat as many fruits and veggies as I can throughout the day since I know I’m going to crave something sweet after dinner (I’ve toyed with the idea of cutting out sugar before… But I honestly feel like I wouldn’t be as happy without it. I know once I got over it, I’d be totally fine… But I just want some simple pleasures in my life #sorrynotsorry).

Moist and fluffy cake with a sweet marshmallow buttercream filling and cereal crunch? Please don’t deprive me! This is my idea of perfection and exactly what I want after a long hard workday. Or, I mean, after any day really…

  7. Such a creative – and delicious – sounding recipe! I can totally relate…I rarely drink milk and the other day had a glass and then did not feel so great, I guess it’s one of those things one has to ease back into…perhaps with one of these woopie pies 😉

  9. I always get a milk chocolate craving when I go to the grocery and never not walk out with at least two bars..haha

  10. I have to laugh. I’m from Maine and Mainers eat BIG whoopie pies. When I bought a whoopie pie pan and made my first batch I thought, “these are not going to bring me back to Maine, are they?”

    …and they didn’t. Last time I used the pan. LOL

    I love how you’ve taken an old favorite and made it new again.
