Remember Circus Animal Cookies? We had totally forgotten they existed and are so happy to have rediscovered them (and kind of scared because they are so good). It’s semi-shameful how many of these were consumed during the making of this recipe, but totally worth it! Who can resist something as happy looking as an Animal Cookie Milkshake? Bring on the ice cream and extra sprinkles, because this is one shake you definitely want to indulge in.
