Do you love birthday cake flavored treats? I do! Have you seen my popcorn mix?! Enough said. I love that this “milk” shake I’ve made fulfills my hankering for ice cream and cake at the same time! Plus, I absolutely love birthday cake ice cream (you’re crazy if you aren’t swayed by sprinkles). You can use any vanilla cake mix that you prefer, but I use this one because I buy one package and use it for many recipes, and I personally love that it is inexpensive and sugar free. You can certainly use a gluten-free mix or any dietary altered mix you love!
