If you haven’t gathered already, I’m kind of a cake person. Ok, in all honestly I’m kind of a sweets person all around. I don’t judge. If it’s sweet, I will eat…that’s my motto. And I fully believe I can live by it, as long as I’m happy that’s all that matters, right?

So I was feeling kind of nostalgic and this Marshmallow Fruity Pebbles Cake was born. Moist layers of white cake are filled with bright colorful goodness then frosted with a ultra delicious Marshmallow Fruity Pebbles buttercream. Seriously it’s like a rainbow within a cake! 

I grew up with Fruity Pebbles being one of my absolute favorite cereals and that is the same today as it was 20 years ago. Being a busy mom of 4 we don’t have a lot of time in the mornings and cereal is one of our go-to options, but cereal isn’t jut for breakfast anymore folks!

I first introduced you to my love of this Marshmallow buttercream here and it is one of the most delicious buttercream frostings out there. Add some Fruity Pebbles to the mix and you have yourself a fruity marshmallowy piece of heaven.

I think there is something about bright colorful foods that intrigue people and draw them in! Once you see this cake it’s like…omg gimme. I need to see what that colorful goodness is all about!

Can you believe that Fruity Pebbles has been around since 1970!!! Now they upped their game and added marshmallows to the mix in this new Marshmallow Fruity Pebbles. Finally a cereal where my kids won’t just go in and pick out the marshmallows and be done with it!

 Around here we like to utilize cereal it in different forms other than in a bowl with milk. Obviously with my track record you can only assume which way I was heading. Dessert! You truly can have cereal anytime! Not to mention that this cereal alone is a great source of vitamins like B6, Thiamin and Riboflavin! It is also naturally cholesterol free! Woo-hoo to that!

I happened to see this new Marshmallow Fruity Pebbles cereal while I was browsing my local Walmart like I’m known to do and knew I need it in my life. So while I was perusing I picked up all the other simple ingredients I needed to make this colorful beauty and hurried home to my kitchen.

You’d be surprised at how easy this cake is to make! Don’t be scared of layer cakes, I was for the longest time and once I started making them more often I got less and less scared and realized that they don’t have to be utterly beautiful (trust me a lot of people don’t judge), they just have to be tasty!

This Fruity Pebbles Marshmallow Cake is just that AND has flavor for days! Moist white cake is layered with blue, yellow and pink buttercream and frosted with marshmallow buttercream (with Fruity Pebbles mix in) and coated in Fruity Pebbles. That coat makes this cake! Each little piece packs a delicious fruity punch with each bite!

What I really love about this cake is that it mixes crunch and creamy together. You have the soft creaminess of the cake and buttercream which is set off by the crunchy fruity burst from the Fruity Pebbles! Seriously you guys, this cake was so much fun! I felt like a kid again making this, just the colors can’t help but make you smile!!

What is your favorite way you’d use this delicious new Marshmallow Fruity Pebbles cereal?

Notes

We like to freeze or refrigerate our cakes before serving, it makes cutting the cakes easier and cleaner. It also sets up the frosting.
