Still looks tasty hehe. I can't resist stealing some of the caramel myself. My wife is a caramel fiend so she always makes a bit extra for us. She recommends the batter thickness to be slightly less runny than pancake batter. "Somewhere between Muffin and Pancake" to quote her exactly lol I hope that helps fine-tune the recipe for you! She also recommends adding more baking powder because "that's what makes the batter rise."
