Olive is 3 years old! When I was writing a post on Instagram about her birthday party, I had to stop and think, wait is she 2 or 3? She’s 3??? Wow. Anyway, this year for Olive’s THIRD birthday, she wanted a gumball machine cake (well at first she said she wanted a bowling alley on top of her cake but I’m not that skilled). She’s still a bit young for gumballs, so I made her the next best thing: a gumball machine cake!

You can see Olive’s first birthday pastel galaxy birthday cake here and her second birthday Daniel Tiger birthday cake here. I always have such a blast making these for her!

This year was a little different because now we have baby Sidney which makes it harder to find time to bake on the weekends. But I strapped little Sid to my chest in her Ergo Baby and went to work! She only lasted about 20 minutes before getting fussy and then I handed her off to dad (fortunately he was home during the birthday cake chaos). You can see a time-lapse video of me filling and frosting this cake with my little helpers here on Instagram.

Since cookies are my specialty, I made a giant gumball machine cookie topper to complete the gumball theme on this cake. I used my cookie pop technique to hold it in place. The small gumballs inside the machine are royal icing transfers (watch the video to see how I made them). And for the cupcakes, I made small round gumball cookies to go on top of each one.

The bright colors on the cookies and cake came from the Wilton Color Right set and I used this nifty cake comb to make the stripes (it took a while to get it right but now that I know how to use it I’m in love with it). See below for the full list of supplies and recipes.

Here are the supplies I used to make this Gumball Machine Cake

  • Homemade Yellow Cake Mix from I Am Baker
  • Vanilla pudding for the filling (I used a boxed mix and added half & half instead of milk. I added 3/4 the amount of liquid that is called for to make it extra thick. It was so good, I will only make it like this from now on!)
  • Crumbled Biscoff cookies for the filling
  • American Buttercream Frosting from I Am Baker
  • Blue & yellow food coloring to make teal frosting
  • Decorating bags
  • Large round decorating tip
  • Large offset spatula for frosting the cake

  • Gumball machine template (below)
  • Small round cookie cutter (around 1-1/2')
  • Acrylic board or upside down sheet tray wrapped in parchment paper for gumball royal icing transfers
  • Scribe tool
  • Black color dust (I used Charcoal from Sugarpaste.com)
  • Alcohol or any flavor extract – Alcohol or flavored extracts are used for painting on royal icing because they evaporate very quickly, which means that the liquid won’t dissolve the icing as you are applying the paint.
  • Paint palette or small dish for mixing paint
