I've made this a few times now. Like many reviewers, I doubled the recipe, decreasing the amount of baking powder to just 2T, I added a bit more melted butter (1.25 sticks for a double batch),  egg, and buttermilk. Also added a bit more sugar, but not too much. I also do my own thing where I add a few healthy dashes of cinnamon to the dry ingredients. I have a fine mesh colander that makes sifting really fast, I recommend not skipping that step. It's a great base - we make blueberry pancakes, peanut butter (literally just stir in pb), and whatever else you want. Make sure to mix dry and wet separately, mix about half the wet in, stir (but don't over stir), then add the rest. 

I'm not sure why I ever used a mix to be honest. These are easier and tastier.
