Shortbread for dessert tonight

I'm making dinner for some friends tonight and settled on shortbread for dessert.  I really like this Martha Stewart recipe because there's no mixer involved and you can add anything you want to flavor the dough.  I used chocolate chips and heath toffee bits that I got on sale at Acme.

Chocolate-Toffee Press In Shortbread
Recipe adapted from Martha Stewart

Ingredients:

• 1 cup (2 sticks) unsalted butter, room temperature
• 3/4 cup sifted confectioners' sugar
• 1 teaspoon pure vanilla extract
• 2 cups sifted all-purpose flour
• 1/2 teaspoon salt
• 1 cup chocolate chips
• 1/2 cup or more toffee bits

Method:

Preheat oven to 325.  Mix all dry ingredients in a bowl.  Then add butter and vanilla and cut in with pastry cuter.  Add chocolate and heath chips and stir to combine.  Press into an un-greased 9x9 baking pan firmly.  Bake for 25 mins or so until golden brown on the edges.  Remove the pan from the oven and let it cool for half an hour then run a knife around the edges and flip it onto a cooling rack.  After the massive square cookie has cooled chop it into square pieces and devour it.
