Mason Jar Banana Bread

Original Pinterest Inspiration (Recipe):
http://allrecipes.com/recipe/janines-best-banana-bread/detail.aspx

Materials:
1/4 cup butter, softened
1 cup white sugar
1 egg
3 ripe bananas, mashed
2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
8 half-pint mason jars
cake pan

Procedure:

1. Preheat the oven to 350 degrees.
2. Lightly grease all mason jars.
3. Cream butter and sugar together in a large bowl.
   
4. Beat in the egg and bananas. I know, it looks gross.
   
5. Mix in the flour, baking soda, and salt, just until everything is combined.
   
6. Scoop or pour portions of the batter into the mason jars. I used a soup spoon. Only fill the jars about 1/2 of the way, so that there is room for the bread to rise.
   
7. Add water to the cake pan so that the water is about 1/2 inch deep.
8. Put the mason jars into the cake pan and put the whole thing in the oven. The water is to prevent the mason jars from heating up too quickly and cracking.
9. Bake for about 40 minutes, or until a toothpick comes out cleanly when inserted into the middle of a bread loaf. The outside of the loaf should be crispy while the inside stays moist and chewy.
