Help! Every time I bake cupcakes from scratch they look like the picture below. The top bubbles and sinks and is just plain ugly. I like a rounded even tone with a smooth top much like that from a cake mix. My cake mix cupcakes come out perfectly everytime but since I sell them I want to make ALL of my cupcakes from scratch. I used Magnolia's vanilla cupcake recipe and baked at 350 for 20 minutes as the directions said. They were raw in the middle at 18 minutes when I checked them (they were getting too golden brown).

woops...the picture did'nt upload. I am not sure I know how to add it. I clicked the attachment but I guess I didn't do something right.

maybe need to try a different recipe, or at least bake at 325 if you really dont want to change.
i use a victoria sponge, never a problem. bakes well at gas 4, whatever tht is!
