Butterscotch Cashew Bars are a delicious blend of sweet shortbread, rich shortbread, and crunchy cashews. These butterscotch caramel bars are a guaranteed hit!
Preheat oven to 350°F (175°C). Spray a 9″x 13″x 2" pan with cooking spray. Using two sheets of parchment paper, line the pan’s width and length, creating a parchment “sling.” Spray the parchment paper with cooking spray.
Using an electric mixer on medium speed, beat the butter, brown sugar, and salt for 1 to 1 & 1/2 minutes. Decrease mixer speed to low and add the flour. Mix just until combined.
Lightly press the dough evenly into the prepared pan. Poke holes in the dough with a fork. Bake for 30 to 40 minutes, until the crust is a golden color. Remove to wire rack to cool.
In a heavy saucepan over low heat, stir together the butterscotch chips, corn syrup, and water. Stir until the mixture comes to a simmer and the butterscotch chips are melted. Pour over the crust.
Sprinkle the cashews over the butterscotch caramel. Bake for 5 minutes.
Cool completely on a wire rack. After cooling, remove from the pan and use a very sharp knife to cut into bars.
