Cake Batter Brownie Snack Cake

Ok, so don’t be confused.

This recipe is brownies.

2 different kinds of brownies

Baked together.

BUT when they bake together they kind of form a cake.

It’s weird, I know.

But it happened.

It wasn’t what I was expecting, but then again, most things aren’t.

Anyhow.  Cake Batter Blondies baked with regular Brownies makes cake.

I have no idea how it does it, but it’s kind of magic.

SO this isn’t really that much of a recipe.

Well, I mean it IS, but it isn’t.

It’s actually more of an assembly process.

Here’s why…

I made the brownies according to the package directions.

Buy the “Family Size” Brownie mix.  The kind you would bake in a 9×13 pan. (I happened to find “Funfetti” Brownie mix, but you don’t have to…it was just a fun option.  The only difference is that it included “rainbow chips” to sprinkle on the brownies.)

Also, you’ll need a box of Funfetti Cake mix.
Two boxes of Funfetti cake mix I used THIS RECIPE FOR CAKE BATTER BLONDIES using the Funfetti cake mix.

BUT I omitted the white chips and the marshmallows.  Don’t be confused.

Whip that up and spread it into a greased 9×13 pan…

Funfetti cake batter spread in a baking dishThen make your brownies, according to the package directions…

Pour that on top of the Cake Batter part…

Brownie batter being poured over top of vanilla funfetti cake batter in a baking panThen, only if you want, sprinkle the top with rainbow chips, or sprinkles.  Don’t worry about this step too much because you’re going to frost over the top anyway.

Rainbow sprinkles being spread on top of brownie batter in a baking panNow they’re ready for the oven.

A glass baking pan of brownie batter with rainbow sprinkles on topWhen they’re baked the layers get all swirly, and in some cases flip to brownie on bottom, Funfetti layer on top.

It’s basically a science experiment.

Then, when it’s cooled, you should frost it.

I mean, it IS cake and all.

I used this recipe cut in half.  Or use a can of frosting.  I mean, who are we kidding here?

Then you should definitely add more sprinkles.

Made this for my hubby’s b-day! Turned out great.

This didn’t really work for us. In fairness, I didn’t use the brands you did. I used a regular white cake mix and a family size (13×9) brownie mix, and it was still totally jiggly wet in the middle after the first check. By the time it was close enough in the middle, the edges were kind of dark looking. It’s edible (with frosting) but dry, and my 7yo ate hers but my 4yo son actually declined eating his piece at all. It’s definitely not up to my normal standards. I’m not sure where I could have gone wrong, it… Read more »

Today was Monday, and even though it’s now spring, IL decided to get cold again. Having to wear my down coat once more made me want alllll the deliciousness and this was the answer. Thanks for getting me out of this Mondaze!

Just made these and they are awesome!!! I didn’t frost them and they are incredible! Great recipe!

Anyone try and make this with their own favorite homemade brownie recipe? I am interested in thoughts on doing this with a homemade brownie recipe. I found the box recipe flavor very overwhelming. I don’t always mind cake mixes but usually find brownies to have an after taste and in this case it completely took over. I LOVE the idea though!

I made this for my daughter’s 9th birthday cake this past Friday (without trying it beforehand) and it was amazing. I followed all of your directions and did 1/2 the buttercream w/ sprinkles on top and I thought it was super delicious. I was so surprised by the consistency and how well the 2 mixes blended together. Super yum!

mine was definitely not done in 25-30 minutes. It’s been in for almost an hour now, and I am kind of frustrated. Hope it turns out ok. I have it on 350. not sure what the problem is. the middle is still very gooey.

I’ve made these several times. The baking time is way off. I have to keep adding another 5-10 minutes. I check to see if the center comes out clean. I do like these but the cooking time needs to be adjusted.

Did the cake naturally swirl or did you swirl it at all?

Do you think this would work as a cupcake?

Yay! You’re back! These are so pretty and look so yummy. I super~love Cookies and Cups recipes. 🙂

This recipe is dangerous because calling them snack cakes leads me to think it’s ok to “snack” on a whole pan without the consequence of calories. Which I would readily do.

You had me at cake better. And then again at brownie. Oh, and then you had me again at snack cake. These look fantastic!!

February 5, 2013 8:31 am

those look amazing!

These look yummy! Also, I don’t know if anyone else has had this problem, but when I try to enter your website, my browser warns me that I’m at risk from your site. Just a heads up. (I use Chrome is that makes a difference)
