Cake Batter Blondies are chewy, sweet, loaded with sprinkles, and topped with marshmallow buttercream! They start with a cake mix, with a few added ingredients including marshmallows to up the chewy factor! The prettiest blondies you will ever make!
Top these blondies off with my sweet Party Frosting aka Marshmallow Buttercream!
Cake Batter Blondies are the Perfect Party Dessert!
I made these Cake Batter Blondies way back in 2011, but thought they might need a little facelift! I snapped a few new pictures and thought that I’d bring these beauties back up to the top of your newsfeed again!
What’s not to love about a sprinkle filled, buttery bar topped with fluffy marshmallow buttercream frosting? If you’re looking for a party party treat, this is the easy dessert recipe for you!
It All Starts With A Cake Mix!
The beauty of these blondies is they start with a cake mix! I used Funfetti, because SPRINKLES! But you can certainly use any flavor that you would like. If you’re going for that true “cake batter” flavor, I do recommend that you use any version of vanilla.
Starting with a cake mix is definitely a short-cut. You use the dry cake mix as an ingredient, so don’t prepare the cake according to the package directions. Use it as you would any other dry ingredient.
Add Marshmallows!
Adding marshmallows into the batter makes these blondies extra chewy! It’s a pretty simple ingredient to add that really amps up the chewy factor. They kind of melt into the batter as it bakes, like a secret sweet ingredient.
Ingredients For Cake Batter Blondies…
- 1 box vanilla cake mix. I used Funfetti, but you can get creative with other flavors!
- Vegetable oil
- Egg
- Milk
- White chocolate chips. If you use a chocolate cake mix you can use chocolate chips instead! Or if white chocolate isn’t your thing you can leave them out!
- Mini marshmallows to add extra chewiness
Add Frosting…Or Don’t…
If frosting isn’t your thing, you can absolutely leave it off! I made some without and added some extra sprinkles on top instead.
These blondies are very sweet already, so leaving it off is fine, although I am always up for adding frosting when I can.
I do like to press sprinkles into the top, though, as the batter is a bit thick and the tops of these blondies can be a bit lumpy and not as pretty when baked.

Belch….those sausages ARE just like dog food. I used to hide my dogs medicine in them but he got smart and figured it out.
I am laughing so hard right now that tears are flowing down my face. I just read it out loud to my husband making me laugh / cry even harder. Thank you for that and this delicious recipe!
haha this story cracked me up–thank you! I will never look at Vienna sausages the same way 😉
I’ve made cake batter blondies…but never with frosting. YUM!
I love this post!! I too have been suffering from Pinterest envy. But

Oh Shelly, You brightened my day!:) Love your spin on these~fabulous! I love Pinterest too!
My Mom used to give us cream cheese sandwiches with mayo and lettuce on white bread in our school lunches. I was so embarrassed since all the other kids had normal things like pb&j, cheese or tuna. Little did I know that would be the beginning of my love affair with cream cheese and mayo. Thanks Mom. Ok, back to the recipe at hand. Those things look amazing! A definite keeper!
Another very good recipe. Thank you. May I ask please, where is your cake stand from?
Thanks! I got that cake stand at Homegoods 🙂
