½cuppowdered sugar (sifted) (also known as icing sugar or confectioners sugar) (sifted)
¼cupcorn starch
½teaspoonvanilla
1½cupsflour all purpose**
½cupmini semi sweet chocolate chips
1pinchsalt
*If you use unsalted butter then add a 1/4 teaspoon of salt. Be sure to use a good quality butter, apparently this year 2022, store brand butter quality is not what it used to be. Less fat could mean a dry not so tasty cookie.
**Flour should have at least 11% protein, this keeps the cookies from spreading.
In the bowl of the mixer add butter and icing sugar and on medium speed cream until very fluffy. Then add the salt, cornstarch, vanilla and flour. Beat until very light approximately 2-3 minutes. Stir in chocolate chips or beat on low for 10-15 seconds.
Drop by heaping teaspoon, or roll into balls the size of a golfball and lightly flatten with a fork, place parchment paper lined cookie sheets. Chill for 15-20 while the oven is pre-heating.
Pre-heat oven to 325° (160° celsius).
Bake for approximately 15-20 minutes** until very lightly golden, almost white never browned. Let cool for 5-10 minutes then carefully move to a wire rack to cool completely before serving. Enjoy!
** Start to check the cookies after 10-12 minutes, depending on the size they may take less time to bake.
Notes
If you prefer you can substitute the chocolate chips with chopped nuts or dried fruit or just leave them plain.
How to store whipped shortbread cookies
Your baked cookies should be left to cool then store them in an airtight container at room temperature they will last up to 5 days. I like cold cookies so I actually store mine in the fridge, they will last up to 10 days in the fridge.
To freeze the whipped shortbread cookies
Freeze the completely cooled cookies in an airtight freezer safe container or bag. They will keep for up to 2 months in the freezer. If you are worried about the cookies sticking together, then place the cooled cookies on a cookie sheet and freeze until firm (about 2 hours) then move to the containers or bags. You can also place parchment paper between the layers.You can also freeze the dough, make the dough balls and place them on a parchment paper lined cookie sheet, once they are frozen place in an airtight freezer safe container or bag. The cookies can be baked frozen, just be sure to add an additional couple of minutes to the baking time.
