The only thing I did different was leaving out the cinnamon and reducing the sugar from 2 tbsp. Mix the dry ingredients together and then add the buttermilk. Mix until combined and leave covered for 10-15 minutes.
Heat a pan on low heat. If a drop of the dough dances on the pan, its hot enough. Drop about a quarter cup (or less) at a time onto the pan. When little bubbles begin to form on top, flip it over for a minute until browned. I made tiny dollar pancakes.
