Root Beer Float Cupcakes with Ice Cream Frosting

These Root Beer Float Cupcakes with Ice Cream Frosting are all summer! Using ice cream inthe frosting is a perfect wayto get the ice cream flavor but not worry about the melting!!

These are a two-fer.

They are Root Beer Float cupcakes, they are also “early-birthday” cupcakes…hence the straw AND the sprinkles.

Got it?


So yeah…my kid has a summer birthday, so he doesn’t get a special day designated to him at school…no goody bags to pass out to classmates, no friends making handmade cards to give him, no birthday crown…

The effect of parents letting their guard down in October as opposed to April.

Apparently, though…in the world we live in, where everything is always fair, everyone gets a trophy and there is no last place, my kiddo gets to celebrate his summer birthday during the school year…with a “Summer Birthday Celebration”.

The sweet teachers at the school didn’t factor in, however, that my child also expected presents on his early birthday, deciding that everyone ELSE in the WHOLE school got “Summer Birthday Celebration Presents”.

I let him pick his cupcake flavor instead.  Life is a compromise.

The choice du jour was Root Beer Float Cupcakes.  Cheaper than a new iPod.

PhotobucketThese are an easy Root Beer Float Cupcake with Vanilla Ice Cream Frosting.

Look what I added in there…All Spice and Cinnamon.  Not enough to make it a spice cake, but enough to bump up the Root Beer flavor a bit.

PhotobucketAnd I also added enough Root Beer to make them completely kid-friendly.

PhotobucketWith the batter mixed, I baked them up…

PhotobucketAnd started on the frosting.

It began with some vanilla ice cream.

PhotobucketHonestly, the ice cream doesn’t make a HUGE taste difference, since I used vanilla, but the idea of throwing ice cream into the frosting made me happy.

You need to let the ice cream sit out for a bit so it isn’t frozen…if you make that mistake the frosting will seem perfect until the ice cream melts, and then you will have a melty frosting cupcake.

I know this because, well, I didn’t factor that in the first time.

Yes, melty cupcakes everywhere.

Learn from my mistakes.

After I got the frosting just right, I drizzled it with a little Root Beer syrup, but you could easily use chocolate.

PhotobucketAnd since we couldn’t forget that they were for a “Summer Birthday Celebration” I added some sprinkles…to amp up the birthday-ness of it all.

PhotobucketNo presents, just cupcakes.

Feel sorry for my child.

Yum. I have an obsession with root beer concentrate, and just purchased two more bottles. I think I’ll be giving these beauties a try this summer! Thanks for the tip on the ice cream! Totally something I would have done!

Colleen @ What

Ooooh, ice cream frosting! What a fun, creative recipe!


Love!! Great idea to add ice cream to the frosting!

Ali @ Gimme Some Oven

These are adorable!!! And ha – definitely cheaper than an iPad. 🙂

Katrina @ Warm Vanilla Sugar

Mmm now these are just pretty.


These are too perfect Shelly. I don’t drink soda but I will gladly consume a root beer float…especially in cupcake form!

Mrs. Zoom

Root bear screams summer to me! Now, I’m craving these cupcakes. Plus I love a good two-fer. Thanks for sharing. I’m hosting a kiddie playdate next week and I think I’ll serve these 🙂

Lauren | Sweet Splendor

SO glad I found your blog because I love this idea! I’m adding this to my recipe binder tonight! Thanks for posting!

Debby Pucci

Have to try these, they sound delicious! Thank you.

Karen @ Sugartown Sweets

These are perfect! My grandson’s birthday party is less than two weeks away. He wants a rootbeer & Cars theme. I think i’ve found the recipe! Thank you. 🙂

Well at least they acknowledge summer birthdays at your son’s school. My daughter and I both have Aug birthdays. They never did anything at my school, nor at the school my daughter goes to. It really stinks. Plus having a late summer birthday meant everyone was on their last minute vacations before school started. STinky! Somehow, with an early start to the school year, my daughter gets to have her birthday on the second day of school! How sad is it that I’m jealous? Wah! Maybe it would make things all better if someone magically came over and made these… Read more »

These look out of this world! SO cute!

Averie @ Averie Cooks

These look awesome and I love the straws. Been looking all over for straws with old-fashioned stripes.

I also have a summer bday and was always skipped in school, every year. I can relate to your son!

Erin Deal

Are these regular size cupcakes or mini cupcakes. They kinda look like mini ones in the pictures.


How many does this make?


this cupcakes sounds really good! i mean ice cream frosting?!? <3


Dying to bake these. . . but cannot bake them without the cute little staw accesorization! Where did you get those darling little things!?

sally @ sally

Frosting made with ICE CREAM? Does it honestly get any better? And I just love how the cupcakes are decorated, Shelly! Looks like the perfect way to celebrate a birthday.


I love the idea of root beer cupcakes! It’s so clever. I also think the idea that the school has summer birthday celebrations. Being a summer birthday kid, I always missed the parties that we had for everyone else during the regular school season. Cool idea for the summer babies!

Valérie ( France )

C’est un suplice que de regarder ces gourmandises
Je te souhaite une belle soirée

Katrina @ In Katrina

True story: we just took our 5 year old on a special overnight vacation…no baby brother. We seriously could have just bought him a root beer and he would have been just as excited. We let him have it for the first time and that was his best memory of the whole darn weekend. Yay for root beer.


Ice cream frosting? YUM!!


Don’t get mad. But I actually don’t like ice cream floats. =X


Rootbeer and vanilla ice cream = two of my favorites!
How adorable are these Shelley!
Love the straws!
LOVE the idea of ice cream in the frosting!
That =s MAGIC!!!

Lauren at Keep It Sweet

These are adorable!

Elizabeth@ Food Ramblings

These look amazing! I want to make cupcakes for my rehearsal dinner and these might be the winner 🙂

Sue @ Cakeballs, cookies and more

aw how fun for your kiddo, and I would so have not let the ice cream thaw out, and it would have been a huge mess, and I would have had to eat it all myself.


These are seriously the CUTEST little cupcakes ever!!


This is a blog robbery!!! Obey my rules and no one will get hurt:

Pack these up & mail them to me so I can eat them all in one sitting.

Do as I say and no one will get hurt!!!



Woow looks super tasteful! If only I could pull off cupcakes like this ones. And the ice cream icing? Bah, impossible with my baking skills, hahah, but I’m gonna try over the weekend. I’m sure I will be freezing and defrosting the ice cream for the whole day and my fiance will drink all the beer in the meanwhile 😀

Have a beautiful day!


Note to self…be wary of summer birthday doom when conceiving future children lest you feel compelled to celebrate your child’s birthday twice in one year.

Although…getting to eat these twice doesn’t seem so bad to me!


I really, really love these !!!
They just look, and probably taste, PERFECT :O)

Nikki @Pennies on a Platter

oh lordy. We’ve been downing root beer floats during this whole vacay we’re on! I’m gonna have to take it a step further and make these now!

(My boy has a December birthday, so I’ll have to figure out how to make sure I separate Christmas and his birthday…when he’s old enough to care. I think I’d rather he have a summer (not-in-school) birthday! lol!)

bridget {bake at 350}

Super adorable cupcakes! Loved that you added in the spices, too. You are so smart! Mr. E would love these!

Jackie@Just Add Milk

I’m so happy I found this…. My boys LOVE root beer and their 13th birthday is next month. This is a perfect dessert for that day!!!! Thanks again!!!


I love the idea of ice cream in the frosting but how does it hold up after they are frosted. Do they have to stay refrigerated after frosting the cakes?


This recipe is perfect! Thank you so much. I’ve made root beer cookies before, but when my little guy requested a root beer cake for his 5th birthday, I was at a loss. Yours was the first recipe I tested, and I have no reason to try any others. It’s great! I used the root beer frosting from my favorite cookie recipe (from Lindsey Johnson at Cafe Johnsonia) and it made for an intense root beer experience. 🙂 I may try doubling the root beer concentrate in the cake next time. We love root beer. 🙂


When making the frosting, how long do you wait for the ice cream to melt? Is it suppose to be all of the way melted until soup or just a little bit and then you have to keep them in the fridge? Thanks!!


I find all of your cupcake ideas so very fascinating. I mean ice cream frosted cupcakes? Thats like totes awesome. They also look really delicious


So, my sister in law has a birthday coming up, and she is a Diet Coke drinker extraordinaire. Do you think it’d be possible to make a diet coke version of this? If so, what spices would you use to ramp up the diet coke flavor?
