This sounds like a weird addition to pancakes, but they are really delicious--fluffy inside and super crispy outside and fun to make. I've made pancakes with yogurt before when I didn't have the traditional pancake ingredients. I've also used coconut milk, sweetened condensed milk and other non-classical ingredients. They were all good, but these are even better! I probably found this recipe online, but look at so many recipes that I do not remember exactly. Pancake ingredients are basic: eggs, flour, sugar, butter or oil, some kind of leavening to lighten them up, and a dairy product.
