It wouldn’t be a piñata without a candy surprise in the middle! These multi-striped, burro piñata sugar cookies are frosted together in sets of 3. The middle cookies have hollow centers so you can fill them with a secret stash of mini M and M’S. That way, when you break open or bite into the cookie, the M and M’S come spilling out. Just like a real piñata. Olé!
