Truly Easy Birthday Cakes

You know, a lot of cakes claim to be “easy,” but let’s be real—only about 25 of them actually deserve that label. I mean, have you ever read those blog posts that promise easy cake recipes? I can’t be the only one who raises an eyebrow at them.

Honestly, I’d be more likely to end up with a sticky mess than a beautiful cake. And then there’s the whole piping thing. Using a star tip to frost Elmo or Cookie Monster? Yeah, I can picture it now: one wrong squeeze and I’d have a frosting explosion instead of a cute character!

Ingredients:

Your favorite cake (homemade or store-bought)
Frosting (store-bought or homemade)
A generous amount of sprinkles (any type you like!)
