Baked Oatmeal

I saw this pin Megan Dietz posted on Pintrest who found a recipe on Urban Nester for gluten free baked oatmeal that was altered from a post on Inspired Taste (I hope I gave credit to everyone). What a wonderful make ahead breakfast dish! I adjusted it to what I had in the house.

2 cups oats
1/3 cup brown sugar
1 teaspoon baking powder
1 teaspoon cinnamon
1/2 teaspoon salt
1/2 cup chopped walnuts
1 cup dried cranberries

Mix this all together and spread evenly in a 9 X 13 "brownie" pan that has been well sprayed with cooking oil. Top with two sliced bananas.Preheat the oven to 375 degrees.

Whisk the following ingredients and pour over the dry mixture in the pan (gently jiggle it to spread out the liquid mixture):
2 cups milk
1 egg
3 tablespoons melted butter
2 teaspoons vanilla extract

Bake for 35-40 minutes and eat warm. Wonderful!
