Rich buttery crust with a sweet vanilla-like layer, chocolate, and toffee bits!
Preheat oven to 350°F.
Cream together butter, brown sugar, and flour until well blended and mixture sticks together well.
Press into 9x13 pan.
Bake for 20-22 min or until slightly golden.
Cool for at least 30 minutes while preparing the next topping. (Do not skip this step.)
In a medium pan over medium heat, heat sweetened condensed milk and butter, stirring constantly for 5-10 min or until thickened. It should be very thick.
Spread over the cooled base layer.
BAKE AGAIN at 350°F for 10-12 min or until slightly golden brown.
Remove from oven and sprinkle chocolate chips evenly over the top.
BAKE for 2 minutes longer or until chocolate is shiny and soft.
Remove from the oven. Spread chocolate evenly with a small offset spatula and then sprinkle toffee bits on top.
Cool and cut into bars.
