Carmelita Bars have sweet, crumbly oatmeal cookie layers sandwiching a creamy caramel and chocolate chip filling for the perfect combination of gooey, melty, and crispy in every bite.
In a large bowl, mix together flour, oats, brown sugar, baking soda, and salt. Add melted butter and mix until combined well. Spread half of the mixture in prepared pan, pressing down to cover the bottom.
Bake 10 minutes. When 10 minutes are up, remove from oven but do not turn off oven.
