Instructions

Preheat the Oven:

Set the oven to 350 degrees Fahrenheit. Line a nine by thirteen inch baking pan with parchment paper so you can lift the bars out easily when cool.

Prepare Caramel Layer:

Unwrap all the caramels and add them to a small saucepan with the butter and sweetened condensed milk. Heat gently over medium low stirring constantly as caramels soften. If microwaving use thirty second bursts stirring after each just until totally smooth and creamy. Set aside to cool slightly while you prepare the dough.

Mix Dry Ingredients:

In a bowl whisk together the flour oats baking powder and salt until they are evenly combined. This ensures there are no pockets and your bars rise evenly.

Cream Butter and Sugars:

In a large mixing bowl use a mixer to blend the unsalted butter creamy peanut butter and brown sugar until the mixture is very light and fluffy. This can take three to four minutes. Scrape down the bowl so everything gets combined.

Add Eggs and Vanilla:

Crack in one egg at a time mixing well after each so dough stays smooth. Follow with vanilla extract and mix until blended.

Combine Dry and Wet Mixtures:

Gradually add the dry ingredients to the butter mixture by spoonfuls on low speed or by hand. Stir until just combined do not overmix to keep bars tender.

Fold in Chips and Toffee:

With a spatula gently fold in the chocolate chips peanut butter chips and toffee bits just until they are evenly distributed.

Assemble Layers:

Spread two thirds of the dough firmly and evenly into the baking dish so the bottom is completely covered. Pour the warm caramel carefully over top in an even layer. Spoon the remaining dough over the caramel in rustic heaps so caramel peeks through.

Bake:

Place pan on middle rack and bake for about thirty minutes. The top will turn golden and edges will be set but center may still look a bit soft.

Cool and Cut:

Let bars cool thoroughly in the pan so the caramel can set up. Use the parchment to lift bars out then cut into squares with a sharp knife wiped clean between slices for perfect edges.
