Maggie Moo's Ice Cream and Treatery offers some of the best ice cream in Lancaster. If you are familiar with Cold Stone Creamery, Maggie Moo's uses the same concept. You get to pick your mix in ingredients and your ice cream flavor and they blend it all together for you into some delicious combinations. They have tons of flavors and even more mix ins, so the possibilities are endless. My favorite is the hot fudge brownie sundae. The only downside is that the ice cream is very rich and creamy, so there is no doubt that it has tons of fat and calories.
