Baby Butt Cupcakes {guest post}

Hey Hey! For those of you who don’t know, I’m the oldest of 4 girls…the Starr girls. My sister, Margaret, and her friend Ivy, made these precious cupcakes, of which I thought were too cute, and some-what cruel to eat (eating babies, haha)! Thanks Margaret and Ivy for an excellent and adorable guest post!

Hello! For those of you who don’t know me, I am Margaret Starr, the third Starr girl (and, if I had to guess, the preferred sister). My best friend, Ivy (technically Liam’s aunt, too) and I were absolutely ecstatic about Liam’s arrival that we decided to get creative to occupy our impatience. We gave ourselves a week to find a recipe, pick our ingredients, and make a game plan. However, we got news that Caroline was to be induced that night!

So, this is what we came up with!

Luckily, Eliza, the 4th Starr girl, was in one of her baking moods and was already making a batch of Pop-Tart cupcakes. Out of desperation, Ivy and I “borrowed” her cupcakes to make our baby butt cupcake toppers. Thanks, Eliza!

The topper is made of marshmallow fondant, which is surprisingly easy to make! Here’s how:

Baby Butt Cupcakes


  • Double Boiler
  • 2 cups mini marshmallows (not packed)
  • 2 cups powdered sugar (not packed)
  • ¼ cup powdered sugar
  • spoonful of water
  • food coloring
  1. Prepare a large bowl with the 2 cups of powdered sugar. Set aside.
  2. Fill the bottom pot of the double boiler with water and place it on the stove on medium/high heat. (If you don’t have a double boiler, just use a regular pot on lower heat and keep a closer watch so the marshmallows don’t stick or burn.) 
  3. Immediately add the mini marshmallows and spoonful of water to the top pot. The marshmallows should begin to heat and melt within 5-10 minutes. Keep stirring as they melt into a smooth texture.
  4. Once completely smooth (it took me about 15 minutes), pour the marshmallows into the bowl of powdered sugar and mix by folding them into one another. I would suggest using a rubber spatula. Eventually the mixture will become too thick to mix with a utensil.
  5. On a cold, hard surface (a marble slab or countertop), sprinkle some of the ¼ cup of powdered sugar. Also be sure to cover your hands in powdered sugar, as this is about to get messy!
  6. Remove the marshmallow/powdered sugar glob from the bowl and finish mixing them together on the slab until it looks uniform. This is why you need the powdered sugar on your hands:  It took a knife, Eliza, and 10 minutes to clean my hands off. Feel free to continue incorporating powdered sugar if it gets too sticky. The consistency is supposed to be gummy/malleable, but not too wet or dry.
  7. Finished? Now you can divide the fondant however you feel is appropriate for coloring.
  • To color your fondant, make a bowl-like shape with the fondant and add a small amount of coloring (gel or liquid) to the middle. Incorporate the color by folding the fondant into itself until the color is evenly distributed. This process usually takes a while, so be patient! Just think of the calories you’re burning.
  • From here, you can really do anything you want with the fondant. This is how Ivy and I created our babies:
    • Body: The bodies under the blankets are peanut-shaped fondant pieces with a little bump for the butt. Put a thin layer of icing on top of the cupcake before starting. This acts as glue.
    • Head: The faces are drawn on with food coloring markers and stuck onto the bodies.
    • Toes: These are tricky and take patience, but they’re so cute! Take tiny fondant balls (about 1 centimeter in diameter) and add 5 more teeny tiny balls (about 1 millimeter in diameter) for the toes.
    • Hands: Start with tiny fondant balls as you did with the feet. Flatten them a tiny bit with your finger and use a fork prong to define the fingers. Artificial apoptosis!
    • Blanket: Roll out a sheet of fondant and cut into 2”x2” squares. Lay over the baby’s body, and it should naturally mold over the baby’s figure.

Although Ivy and I never ate any of our assembled babies, the marshmallow fondant was very tasty. We hope you enjoy making these for yourself!


  1. What a sweet guest post. Congrats to Margaret and Ivy! The babies look so good, I thought they were plastic dolls at first. A+ on the photography also. Liam is a lucky boy to have so many adoring fans!!!

  2. Hahaha. I love that picture of the hands! That is me. Every time. I never listen to the directions or common sense. “Oooh, it’ll be different this time! I don’t need that.” LAZY!

    These are so cute! The two of you are super talented. I’ve tried making stuff with fondant and all I can do are pumpkins. It’s sad.

    So is the second Starr girl also a baker? Because that must have been a lot of baked goods for one family. 🙂
