Skinny Funfetti Cupcakes w/ Cake Batter Marshmallow Frosting for Two!


Happy birthday to me! Happy birthday to me! Happy birthday to meeeee, happy birthday to me!!!

Today marks the 2nd anniversary of my 29th birthday and the start of my birthday week, and I couldn’t be more excited!

And the only reason I am excited is because of this flipping recipe.

Ok, maybe not the only reason, but this is by far the best birthday present I have *EVER* given to myself.

What’s that you say?

You want to give me a birthday gift as well by following me on Twitter and Pinterest, liking my Facebook page, and subscribing to my posts?!?

Awwww thanks, y’all!!!! You just made my day even more special!!!

These gorgeous tasty morsels of funfetti fantasticness are like ittybitty bites of birthday heaven hand delivered to moi by the big man upstairs.

And they are only 87 calories and 2 WWpts each!!!!

87 calories!!!!!!!!!!

If you don’t believe in miracles after eating one (or both) of these cuppity cakes then something is clearly wrong with you…bless your heart…

Also, I will never ever, never ever ever make another type of cake icing again. This is the absolute best I’ve ever eaten, and you would never know that it is super low calorie and kinda, sorta, a little bit good for you.

This frosting is ooey, gooey goodness and is taken over the edge by one very special ingredient…

Butter extract.

IMHO, butter extract makes the world go round.

It is that extra special ingredient that makes recipes taste like cake batter without having to actually use cake batter &/or mix.

Another great thing about this recipe is that it only makes two cupcakes.

Hallelujah praise the Lord because if y’all are anything like me, you can’t stay away from cupcakes if they are anywhere within your vicinity. Also, I promise you will never miss the eggs, butter, and oil that are missing from this cake.

The only wet ingredient you will need is a bit of flavored soda water of your choosing and you are good to go! (No soda water? Use diet sprite or cream soda instead). 

My sweet tooth is horrible and unrelenting, but because of this awesome recipe, I have finally found the perfect way to have my cake and eat it…for two!

    Mmm…those look TASTY!

    Chocolate for sure. Tea (unless I have a lot of studying or science to do…then I’ll go for a coffee or a diet coke). I’m a libra!

    Happy 29th bday anniversary to you! I personally haven’t told anyone how old I am in several years. So that by the time I turn 30 (still not there yet!), people won’t know because they won’t remember exactly how many years ago it was when I turned 24. Is that weird? I’ve been told its weird. Oh well…I’m a scientist. We’re weird 😉

      You’re a scientist?!? What do you do? I wish I like math and science. I don’t…at all. In fact, I couldn’t loathe them any more! I told a friend just yesterday that I would rather right a 25 page paper than take one chemistry test! Ha!

    • amber says

      Thanks so much! They really are the perfect cupcakes. I’m so glad they only make two! I would be in trouble if I made more!

    • amber says

      Butter extract is da bomb!!! If you haven’t tried it yet, do it! It’s so good and tastes just like cake. Weird, but true!

  2. Cindy says

    I need this recipe using the whole box of cake mix and how to make enough icing for 24 cupcakes! I want to make these for my daughters birthday party!

    • amber says

      Hi Cindy! Use one standard box of cake mix and one standard size size can of diet sprite or cream soda (12 Oz, I think?) for the frosting If you just want a little bit use 4 large egg whites, 1 cup granulated sugar, 1 tiny pinch of salt, 1/2 tsp vanilla extract and half a tsp of butter extract and follow the directions on my site. If you want a lot of frosting, double those measurements. Hope this helps! Let me know how they turn out!
