Step 1

Preheat the oven to 350ºF. Spray an 8x8" baking pan with cooking spray, or line it with parchment paper. Using parchment paper will allow you to easily remove the bars from the pan and cut them evenly.

Step 2

In a medium size bowl, mix together the flour, sugar and melted butter. Press this mixture into the bottom of the prepared pan. Bake for 20 minutes.

Step 3

In the same bowl, mix together the toffee bits, sweetened condensed milk, vanilla and chopped pecans. Pour this mixture onto the crust. Bake for another 20 minutes until the top is bubbling.

Step 4

In a microwave safe bowl, melt the chocolate chips in 15 second intervals, stirring between each interval, until the chocolate is melted.

Step 5

Drizzle the chocolate over top the baked bars.

Step 6

Allow the bars to cool completely, then cut them into squares.

Step 7

Store in an airtight container at room temperature for up to 3 days. Then refrigerate or freeze.
