Gooey Oatmeal Chocolate Bars

This is a super yummy treat that a friend of mine made for "Birthday Sunday". I almost prefer them to cookies. The oatmeal in them is fabulous! They are kind of messy but oh so good. :)
INGREDIENTS
1.5 cups flour
1.5 cups rolled oats
1.5 cups brown sugar
1/3 tsp salt
3/4 tsp baking powder
1 cup melted butter
1/2-3/4 bag of chocolate chips
1/2 cup or more caramel sauce

Mix flour, oats, sugar, salt, and baking soda in a bowl. Melt butter and add to flour mixture. Stir until combined. Pat down 3/4 of the mixture in a 9x13 pan. Bake at 300 degrees for about 10 minutes (it won't look done). Drizzle caramel on top while hot. Sprinkle chocolate chips evenly on top of caramel. Crumble the rest of the mixture on top and bake at the same temperature for 15 minutes or so. Allow to cool completely for easiest cutting. Then enjoy!

I have tried mint chocolate chips and love how that tastes. I wonder what it would be like with butterskotch or chocolate syrup? It won't look done when you take it out of the oven. But once it sets up it's super good. I usually let it sit overnight.
