Preheat the oven to 425 degrees F or prepare barbeque grill.

Cut off the ends of the bananas. Place the unpeeled bananas on an ungreased cookie sheet or in a baking pan or place the bananas on the lightly oiled rack of barbeque grill. Bake or grill for 15 minutes, or until the skins burst and turn black. Discard the skins and cut the bananas lengthwise. Mix the butter, brown sugar, and lemon and drizzle over the cooked bananas. Serve with ice cream.
