In a glass bowl, unwrap the caramels and add the evaporated milk.

Melt in the microwave in 30 second intervals, stirring between.

Set aside.

Heat the oven to 350.

In a bowl, combine the melted butter, brown sugar, flour, oats, salt, and baking soda.

Stir to combine and press 1/3 into an 8x9" pan.

Bake for 8-10 minutes and remove from the oven.

Lay the chocolate down, top with caramel and twix and sprinkle the remaining crust mixture on top.

Bake an additional 15 minutes and set aside to cool before cutting.

Or serve warm, which is our favorite but more messy
