There are a couple of things you want to remember when making them. The dry ingredients and wet ingredients are mixed in separate bowls and not combined until you’re ready to make them. Let your buttermilk , milk and eggs sit out to room temperature before mixing with the cooled melted butter. If they are cold ,the melted butter will solidify and you’ll have butter chunks. When you’re ready to mix the dry and wet ingredients together, only mix until the ingredients are incorporated. The batter will be lumpy, you want it that way.
