Step 1

Preheat oven to 350°F. Line a 13x9-inch baking dish with parchment paper leaving a 2-inch overhang on all sides. Spray paper with cooking spray, set aside.

Step 2

Bars: In a medium-size mixing bowl use a whisk to sift together the flour, baking powder and salt until combined.

Step 3

In a separate large mixing bowl, use a whisk to stir together the brown sugar, melted butter, vanilla and eggs until smooth.

Step 4

Add the dry ingredients to the wet mixture stirring together until fully combined. To the batter add 1 ½ cups butterscotch chips. Stir to distribute.

Step 5

Spread batter evenly in the prepared pan. (It will be thick) Sprinkle the top with 1/2 cup reserved butterscotch chips.

Step 6

Place into the oven and bake for 25-30 minutes r until the top appears dry and set and a toothpick inserted into the center comes out clean. Cool completely in the pan on a cooling rack.

Step 7

Butterscotch Glaze: Place the remaining 1/2 cup butterscotch chips and heavy cream in a microwave-safe bowl. Microwave in 15-second intervals, stirring in between repeating this process until they're completely melted and smooth.

Step 8

Lift bars from pan using the parchment paper "handles". Cut into desired size bars. (You can slice into 12 or 16 bars.)

Step 9

Pour melted butterscotch into a piping bag or a plastic Ziplock bag with the corner snipped off. Drizzle the glaze over the cut bars, let them dry for about 20 minutes to set, then serve.
