Dunkaroo inspired cake

As a kid, there was pretty much no bigger score than opening your lunchbox and seeing that bright blue Dunkaroos tube. You were instantly the coolest kid at the lunch table, with people offering up their Uncrustables, their chips, and their juice boxes in hopes that you’d trade them for your sweet treats. In case you missed it, Dunkaroos are back – they’ve relaunched at select stores, but are still pretty tough to find. So, I did what any normal person would do, and made a cake that tastes just like them. Behold – Dunkaroo cake.

The Cake

This cake is a basic funfetti, but lightened up. I am a firm believer in making a slightly healthier version of your favorite dishes, so I’m always experimenting with reducing sugar/butter, sneaky swapping in healthier ingredients, and lowering the caloric load that comes with eating cake on the regular (sorry not sorry). For this funfetti cake, I reduced the sugar down to just half a cup, whereas most cake recipes call for a cup or more (eek!). If you remove the sprinkles, you’re left with a plain vanilla cake which is super versatile!

Simply frost one side, flip the other on top, and frost normally!

This way, you end up with a two-layered cake, but only one half of it, which is perfect if you’re a small family (or a hungry single person). You can also leave it as one layer and frost the entire thing – it’s just as delicious. 

If you have more of a crowd and want an entire 9″ two layer cake, then double the entire recipe and frost accordingly!


The Frosting

This frosting is just as good as the one you’d find in that iconic blue tube. It starts as a basic buttercream (yep, I reduced the butter/sugar there too and it’s still insanely good), and I added in Cool Whip, which is low in calories, to fluff this frosting up. I whipped the frosting in my KitchenAid Mixer, which makes frosting (and life) so much easier. If Funfetti isn’t your thing, omit sprinkles and you’ve got a fluffy vanilla frosting that can go on just about anything. Also, you can substitute the milk with a plant-based milk if need be!

I turned your childhood favorite snack into a delicious cake that tastes just like the good stuff in the neon blue tube. This makes one 9″ round cake, which I like to cut in half and stack and frost, so I only end up eating half a cake instead of an entire one (self control is not a strong suit). If you’re looking to make a full layer cake, double everything!
