1cuproasted macadamia nuts (coarsely chopped)optional but good!
Instructions
Preheat oven to 375 degrees F. If making larger cookies, you may want to use 350 and bake slightly longer.
In a mixing bowl, using low speed of a stand mixer, beat the butter, shortening and both sugars just until mixed (not light and fluffy, just mixed). Gradually add the eggs, stirring just until blended. Then stir in the vanilla and Vodka.
Combine the flour, cornstarch, baking soda and salt in a separate bowl and stir well. Add the flour mixture to the butter mixture and stir until blended. Stir in the white chips (and macadamia nuts, if using).
Drop dough by rounded tablespoons (or scoop with a medium size cookie scoop) onto a parchment or nonstick foil lined baking sheet. Bake for 12-15 minutes or until cookies are nicely browned all over. Makes about 32 to 36 depending on how large you make the cookies
Notes
If you don't have a scale and can't weigh out 12 oz of flour, measure by volume using a very light hand. That is, scoop the flour into the cup and level it off with a knife.
