1 1/2 cups plain Greek yogurt
3/4 cup peanut butter
2 tablespoons pure maple syrup
3/4 cup chocolate chips (can use more or less to taste)
Store bought graham cracker crust (or make your own, but then it's more than 5 ingredients)
Mix yogurt, peanut butter, and maple syrup in a large bowl. Stir in chocolate chips.
Spread into pie crust.
Cover and freeze for several hours (until solid). Serve and enjoy!!
