Here's a super-cute project that, while time consuming, is very fun and relatively easy to make. I used a cake mix (from the box) but changed it, as per the instructions in the back of the Hello, Cupcake! book this recipe comes from. In spite of the warning in the book about not using a mix with pudding, that's what I used because it was all I had on hand. Also, I used whole milk and lemon juice instead of buttermilk, again because it was what I had on hand. The cupcakes domed nicely and were very sturdy. One box made enough cupcakes to have 12 large and 24 mini owls.
Many thanks to Kimball, who split the eyes for me. I'd suggest actually buying Oreos instead of a knockoff (which is, unfortunately, what I did). The mini Oreos came apart very easily, but the large cookies weren't Oreos and they were a pain in the neck to separate!
