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.

  1. Yummy!! Thanks for sharing! The Brady’s were great – kids today (boy, does that make me sound old or what) need good TV like that… so sad. Here in Utah, the local channels play Brady Bunch reruns almost every weeknight! ๐Ÿ™‚

  2. Ah we both posted root beer treats tonight! how awesome! those brownies sound and look amazing and I am super jealous of your root beer float topping..we can’t even buy regular root beer in supermarkets here in England, let alone super cool dessert topping! p.s loving the new blog, usually just read your posts in reader but popped over and am loving the new header!

  3. Well those look just yummy! I’m sitting thinking about baking brownies now. MMmmm. I am also nostalgic and a huge fan of old tv. I, too, grew up with the Bradys in syndication every afternoon. We really need more wholesome TV. Great Post!

  4. Oh – I am there with you! I LOVDED the Brady Bunch!

    I was in love with Greg. Wanted Jan’s hair, but didn’t like her. I also thought Marcia was a bit of a snob. I wished we had an Alice and wanted the entire house – astro-turf and all (dibs on the attic!)

    Fabulous brownies!

  5. 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.

    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!

  7. 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. ๐Ÿ™‚

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

      That is SO awesome!! I hope someone snapped a pic, but I guess that was prob before camera phones ๐Ÿ™
      I am truly impressed!!

  8. 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.

    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 LOVE the Brady Bunch. It’s so fun to share my youth with them. And, they haven’t asked about those 2 missing channels once!!! This recipe is awesome – can’t wait to make it! Thank you…

  10. i wasn’t the biggest brady bunch fan, although i love the theme song and i always appreciated alice. ๐Ÿ™‚
    great brownies, shelly–terrifically unique!

  11. 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.

  12. 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!!

  13. I am a Pampered Chef consultant, and I can’t wait to make individual Root Beer Float Brownies in our fantastic Brownie Pan! I can also use many our of products to make the batter and frosting as well. Thanks for a great recipe! I’ll be using my husband as my guinea pig (uh, taste tester!) really soon as he LOVES root beer floats!
