Adapted from Taste Magazine Winter 2012, Toffee Crunch Shortbread pg. 170
Makes 3-4 dozen
2 3/4 cups AP flour
2/3 cup corn starch
3/4 lb salted butter, softened
1/3 cup white sugar
1/3 cup tightly packed light brown sugar
1 1/2 cups toffee baking bits
Preheat the oven to 325 degrees F.
Butter the bottom and sides of a 13×9 baking pan and line the bottom with parchment paper, leaving enough overhang on two sides to create handles to lift the shortbread out of the pan when done baking.
In a large bowl sift together flour, cornstarch and salt and set aside. In a food processor fitted with the blade attachment, cream together butter and sugar until completely incorporated, scraping down the sides as necessary. You may use a stand mixer or hand mixer for this also.
Add the flour blend 1/2 a cup at a time, making sure the flour is completely mixed in before adding more. If the dough becomes too thick you may need to knead in the remaining flour. Knead in the toffee bits until evenly incorporated.
Press the dough firmly into the parchment lined baking pan. I recommend taking a second piece of parchment paper and using either a rolling pin, if you can fit it into the pan, or a metal spatula to create a smooth surface. Prick the surface of the dough with a fork all over to allow steam to escape while baking.
Bake in the centre of the oven for 30 minutes. Remove from the oven and prick the surface again to ensure air bubbles have not formed under the surface of the dough.
Bake for another 20 minutes or until the cookies are lightly browned around the edges.
Remove from the oven and place on a cooling rack for 5-10 minutes before attempting to remove the cookies from the pan. This is important to prevent the cookies from becoming shortbread crumbs. Carefully lift the shortbread out of the baking pan, and onto a cutting board. Cut the shortbread lengthwise into three long pieces, and then cut each into four pieces. You may now cut each of these pieces into 2, 3, or 4 pieces depending on how large you’d like them. I suggest cutting into thirds making 36 pieces. Allow the shortbread to completely cool before transferring to an airtight container.
