Not birthday cakes, but could be. Thank you to cakes by Kris for this idea it was fun! This is lemon cupcakes, with chocolate fudge injected. Pastry pride frosting and marshmallows. I must "sheepishly" admit I used a sharpie to make the faces......... I know that is a big no no, but I didn't have the black edible marker. I'll pick one up next time. It was only a tiny bit, but still... not something good to do.
