I've baked thousands of cupcakes and only just last week did I have this problem of the liners not sticking. I made the King Arthur Flour White Cake (on the recommendation of MANY who'd made it) but I made cupcakes instead of a cake. I pulled them out of the oven and the papers had already started to pull away from the cake. As they cooled, ALL of them pulled away. Not only that but they were like little gut bombs. No flavor, flat on top, hardly any rise and they were just YUCK! I checked my baking soda and powder for expiration dates and they were fine and every other batch of cupcakes I've made since then have risen just fine. I totally don't get this.
I do sometimes have difficulty getting a nice dome as well and I've found that each recipe does have its own nuances; some rise, some don't. I'm not quite sure how to remedy this other than using a box mix and doctoring but I'd like a good light chocolate cupcake recipe (like a German chocolate) that rises and gets a nice dome. I made the recipe from the Baker's sweet chocolate package and the flavor was awesome, but they ended up flat as a pancake on top with a holey/spongy kind of top. Weird.
