Root Beer Float Brownies

Root Beer Float Brownies have root beer baked right in! The root beer pairs perfectly with the chocolate and it’s all topped with Root Beer Buttercream!

I am always looking for a new, fun way to enjoy brownies! Plus, my kids a re huge root beer float lovers, so I thought it would be fun to combine the two!

First you start with delicious chocolate, both white and dark.  I’m an equal opportunity baker.

And then there’s the Root Beer..use whatever kind you like…just let it sit out a bit so there’s no foam.

After I baked up the brownies I let them cool…but I had to try a little bit know,  for research.

The root beer in the batter gave the brownies a fine crumb, but the melted chocolate gave them a rich fudgy texture.  Really yummy!  You can’t taste the root beer in the brownies, it just changes the texture and adds a layer of sweetness.

Then of course I topped the brownies with Root Beer Frosting and a quick drizzle of chocolate syrup. Perfection!

The frosting has a subtle root beer flavoring from a little root beer extract, but if you wanted less you could leave the extract out.

I’m not much of a root beer lover but Jason is a root beer FANATIC so I definitely have to make these for him!


Hi, I found your blog through pinterest, and I love it!! You inspire me! Can I ask, how do you have the special recipe card background? It’s so creative, and stylish. Keep posting…you’re a really good writer!!


The 1/2 tsp salt is missing from your recipe card! 🙂


You can watch the Brady Bunch online for free! 🙂 Just thought I would spread the Brady love.


The Brady Bunch just makes me feel like a Sunshine Day…I think I’ll go for a walk outside now. Okay, I’m back. You cannot beat the BB for good, clean fun. I love the Silver Platters, Johnny Bravo, Davy Jones guest starring, etc.


i wasn’t the biggest brady bunch fan, although i love the theme song and i always appreciated alice. 🙂
great brownies, shelly–terrifically unique!


A couple of weeks ago I finally got tired of the shows my girls were watching on Nick & Disney; all the kids were lying to their parents and being mean to others (and not in the more innocent way they used to in the 70’s). So, I went to Amazon and purchased the Brady Bunch boxed set for them to watch. Then, after locking out those 2 channels on our tv, told them our service had changed and we don’t get those channels anymore. Not honest, I know, but I’d like to preserve their innocence a little longer. They… Read more »

Wanna know MY favorite line to repeat from Brady Bunch?

Pork chops and applesauce…swell. (said in a Humphrey Bogart voice, duh)

Peter finding a personality is the BEST episode evah.


The brownies look great.

megan @ whatmegansmaking

I’d like one of these while watching the brady bunch please. That would be perfect!


Just when I think you can’t top something, you go and do it again! Brilliant. And ditto kick buttkowsk. What the heck is it anyway lol. Cant beat the brady’s!


I’m about to make you very jealous. When I was a little girl, I got to stand BESIDE Alice for a Christmas Eve service. How cool is that? Do I remember it? No, not really; I was a bit too young, but my mother told me I was just excited as all get out to have that honor. 🙂

Just had to pass it along because you will appreciate it more than most people ever have. LOL!


Oh, you make me laugh Shelly:) These brownies sound amazing! The root beer float syrup is the perfect topping~what a great find!


Oh Holy Cow! The tiki-idol thing is so funny! There is actually a station in KC that plays all older episodes of fun shows ala Nick at Nite…..and that exact Brady episode was on and I watched and laughed!


Are you kidding me? Root Beer Float brownies? I may just die.
I rarely got to watch the Brady Bunch (not sure why) but the one with the house of cards contest they had still has stuck in my head.

I remember “playing” Brady Bunch on the playground in our neighborhood. I always wanted to be Cindy b/c she had those yarn ribbons in her hair. 🙂
