Here's what you need:
an apple (I use Gala)
brown sugar or maple syrup to taste
-preheat oven to 375°-cut vertically & core an apple
-poke a few fork holes in there for heat to escape
-put around a 1/2T of butter in what is now the apple valley (duh)
-fill up the remaining space with either brown sugar or maple syrup (or both, holla!)
-place in baking receptacle & bake for 45 min (it's not an exact science- I like my baked apples kind of soft)
They should be bubbling and smelling delish. Be careful: apples retain a lot of heat for a lot of time. More than once I've eaten through the pain. I'm not proud of it.* Put as much or as little (don't be a puss) topping as you want.
*yes I am.
