Step 1

Preheat oven to 325F and line 2 cookie sheets with parchment paper.

Step 2

In a medium bowl, toss together the flour, powdered sugar, cornstarch, and salt. Set aside.

Step 3

In a large mixing bowl, beat the butter and vanilla until light and fluffy.

Step 4

Slowly mix in the dry ingredients until almost combined. Then fold in the toffee bits until just combined. The dough might seem dry and crumbly but it will come together when you roll it in your hands.

Step 5

Scoop the dough using a tablespoon or cookie scoop. Roll the dough into a ball and place 2″ apart onto the prepared baking sheets. Flatten slightly with the palm of your hand.

Step 6

Bake for 15 minutes or just until the bottoms start to brown. Let cool for 10 minutes before serving.
