How do I make DOMED cupcakes?

I have a feeling its the recipe your using because I like to compare my homemade baking results with box mixes, and usually, box mixes produce muffin-shaped cupcakes. With my baking, I usually, like the other person said, fill up the cupcake liners more, instead of making more cupcakes (so 16 cupcakes would be like 12 large cupcakes). Also, I'm not sure if you're doing this, but don't even/smooth out the cupcake batter in each well. If you leave it alone after you dump it in, it should probably rise to make a dome shape. Finally, about the cupcakes being hard, I have two tips. First, make cupcake recipes that are strictly for cupcakes (they aren't derived from/based off of a cake recipe). Second, some recipes just come out bad. Just try a bunch and decide which flavor, shape, etc. you like the best.
