These Hotteok are a popular Korean street food made with yeast dough and filled with a melt-in-your mouth mixture of brown sugar, cinnamon and walnuts. These sweet Korean pancakes are super easy to make and addictively delicious. The melted brown sugar filling warm, gooey and just SO GOOD. This Korean street food is traditionally served in the winter, but is good all year round. #wenthere8this #hotteok #koreanpancakes #koreansweetpancake
