The next Great American Bake Sale featured item is the humble kolaczek (kolaczki is plural). Amidst my eternal indecision of what to bake for the masses, I decided to embrace my heritage and attempt a Polish mass of white ingredients.
I grew up eating kolaczki, but they were always store-bought or restaurant-made. Most of the time, they are anemic pieces of dough folded over filled with either more white stuff (cheese), or a fruit jelly, then garnished with powdered sugar (even more white stuff). The following recipe I got from a great chef who makes the best [foie gras] pierogies I know. It doesn't include baking powder, which is an ingredient that seems to be up to much debate in online grandma forums.
