Birthday Cake Cupcakes

Time for a birthday par-tay.Creme de la Crumb is officially one year old today! That is crazzzzzzy. And we are celebrating. With, well, birthday cake. Duh. Except they’re birthday cake cupcakes. Cause I’ve been in a cupcake mood lately. And I sort of feel less psychotic if I eat seven cupcakes instead of seven pieces of cake, ya know?

That sounded less embarrassing in my head.

And if we are being totally honest here, I like these cupcakes wayyyyyy better than any cake I’ve had at any birthday celebration. In my experience birthday cake tends to be dried out and the frosting is too rich.  But these cupcakes solve both of those problems. And they start out with a cake mix! (No shame here, I’ll take a shortcut.) Don’t follow the recipe on the back of the box though, this recipe is much much better than that.

So. Without further ado, here’s to a pretty awesome first year of blogging, a whole lot of life changes, and to learning to boil water.

Here, have a cupcake. Mmmmmmmm.
