Step 1

Preheat oven to 350º and line a 8 x 8 inch baking pan with parchment paper.

Step 2

Beat butter and brown sugar until combined, add flour and mix. It should look like cookie dough. Press into the prepared pan and bake for 15 minutes until lightly golden brown.

Step 3

Combine condensed milk and butter in microwave safe bowl and microwave until the butter is just melted, about 1-2 minutes. Pour over shortbread and bake for an additional 12-15 minutes until it is bubbly and starting to turn brown.

Step 4

Remove from oven and immediately sprinkle chocolate chips over the top. Return to the oven for 2 minutes. Remove and using an off-set spatula, spread the chocolate chips evenly over the top. Sprinkle with toffee bits and chopped pecans and press them into the chocolate mixture. Let cool completely. Refrigerate before cutting.
