Ingredients
Method
Prepare the crust
- Melt the butter completely.
- Mix melted butter with oatmeal, flour, and brown sugar.
- Press 2/3 of this mixture into a greased 9x13 pan and bake at 325°F for 10 minutes.
- Allow the crust to cool and set the remaining 1/3 of the crust mixture aside for topping.
Make the filling
- Melt the butter for filling in a saucepan over medium heat.
- Stir in brown sugar until smooth, about 1 minute.
- Repeat the process for adding milk, vanilla, and flour, stirring after each addition.
- Bring to a slow boil for about 3 minutes until it begins to thicken, stirring continuously.
- Remove from heat.
Bake the bars
- Once the crust is cool to the touch, pour the caramel filling over it.
- Sprinkle the remaining crust mixture over the top.
- Bake at 300°F for an additional 20 minutes. The bars will appear a bit runny but will firm up when cool.
Notes
For maximum gooeyness, serve warm with vanilla ice cream. Store in an airtight container at room temperature for up to 3 days.
