The inspiration for this oreo funfetti cake is my Husband. He loves Oreos and funfetti cake, and I wanted to make him a special cake for his birthday.

I was gone for his birthday last year, so I hoped this year’s cake would make up for that!

What Types Of Sprinkles Should I Use To Make This Oreo Funfetti Cake?

While you might think all sprinkles are created equal, sadly you’re wrong. When making a funfetti cake, you have to be sure you use the right type of rainbow sprinkle.

The best sprinkles for this are rainbow jimmies. They are the longer sprinkles that you used to (and may still) put on your ice cream.

These sprinkles keep their color, and won’t immediately bleed into your batter.

This is important, because it will help your batter say white while you add it to your pans. This will allow the color of the sprinkles to really shine through once the layers are baked.

The type of sprinkle you should NOT use are the tiny, round, rainbow sprinkles. They’re called nonpareils, and they are the true enemy of funfetti cakes.

Nonpareils will start to bleed their colors the second they’re stirred into your batter, resulting in a creepy, pink/grayish batter.

This can also happen if you let your rainbow jimmies sit in your batter for too longer, and then try to stir it.

The key takeaways? Only use rainbow jimmies in this oreo funfetti cake recipe, and immediately pour the batter into your cake pans once it’s made.

Why Use Caramel Buttercream on This Oreo Funfetti Cake?

Why NOT is the better question!! Just kidding…kind of.

My husband is quite a picky eater, and is equally selective when it comes to cake flavors. He only really likes a few flavors of frosting, and caramel buttercream is at the top of that list.

So yes, this is a funfetti oreo cake frosted with caramel buttercream.

It might seem like there’s a lot going on in this cake, but I promise all the flavors actually come together quite nicely.

If this is too many flavors for you, you can always frost this cake with my vanilla buttercream recipe instead.

The Inspiration Behind This Cat Cake Decoration

It’s no secret that my husband loves cats. I’m sure down the road we’ll get a nice little kitty, but we aren’t allowed to have pets in the building we currently live in.

For the time being, a cat cake is about the best I can do. I’ve never been great at making super realistic cakes which usually use lots of fondant or modeling chocolate.

I like to make cakes inspired by cute cartoons with buttercream. They’re more fun to eat, and a heck of a lot more fun for me to make.

That was my game plan for this cake, and I’m in love with how it turned out! It’s equal parts adorable and silly, and I’m here for it.

How to Make This Adorable Cat Cake

This cat cake isn’t too complicated to make, but it was a process! Below are the steps I took create this look.

Step #1: Trim Your Cake Layers

After your cake layers have baked are fully cooled, I recommend leveling them with a serrated knife.

Once they’re leveled, you can trim the sides of two of the layers to begin to create the round shape of the cat’s head.

This makes it a lot easier to get the shape you’re after, and makes frosting the cake a lot simpler.

Step #2: Fill and Frost The Cake

Next I used the caramel buttercream to fill and crumb coat the cake. I chilled it for 10 minutes in the freezer, and then added a second thicker layer of frosting.

After that I smoothed the curved sides with an acetate sheet. You can use a small offset spatula if you don’t have acetate sheets on hand.

I divided the remaining frosting into two bowls. Then using gel food coloring, I colored one bowl gray and the other orange. I placed each frosting in its own piping bag, and cut a 1 cm opening.

With both colors of frosting I piped overlapping patches on top of the cat’s head to look like big spots. Then I cut out triangles of fondant and secured them on top of the cake with toothpicks.

Once the ears were in place, I covered them with matching buttercream and smoothed it out using a small offset spatula.

Step #3: Make the Cat’s Cute Little Face

While I’m a buttercream girl through and through, there is a time and place for fondant. This is it.

Piping buttercream details for a face can be extremely challenging. While it can be done (I somehow managed to on my Grinch cake), I thought it would look better to use fondant for the cat’s face.

I used a bit of black, pink, and white fondant to make the cat’s eyes, nose and mouth.

Step #4: Celebrate and Enjoy!

The last step was to add the fondant features onto the buttercream cake with a tiny bit of extra buttercream.

Then it was time to cut in and enjoy! And yes, party hats were involved 🙂

Tips for Making This Oreo Funfetti Cake Recipe:

• Chill your cake layers in the freezer for about 20 minutes before assembling the cake, to make it easier to stack and frost.
• Mix your cake batter just until the ingredients are incorporated; this will ensure your cake layers are tender and fluffy
• Use a serrated knife to level your cake layers once they’re fully cooled, to make it easier to assemble and frost your cake
• I do NOT recommend using this recipe to make cupcakes! Instead, I highly recommend trying my funfetti cupcake recipe (I like the texture better for cupcakes). Swap out half the sprinkles for crushed oreos
• Use my small batch funfetti cake recipe to make a 6-inch layer cake, and swap out half the sprinkles for crushed oreos

Making These Cake Layers in Advance and Storage Tips:

• Make your cake layers in advance and freeze them: It breaks the process up and make it more approachable.
• Make your frosting ahead of time too, or save any leftover frosting! It can be stored in an airtight container in the fridge for up to a month, or in the freezer for up to 3 months. Be sure to give it a good stir once it thaws to get the consistency nice and smooth again.
• A frosted cake can last in the fridge for up to a week, or in the freezer for up to a month. The buttercream locks in all the moisture, keeping the cake fresh and delicious!
• If you cut into the cake and have leftovers, use any remaining frosting to cover the cut section to keep it moist and store in the fridge for up to a week.
