Everyone's favorite sweet treat for all of the holidays, these cutout sugar cookies are a staple in our household. They hold their shape while baking, don't require any chilling time, and are reaaaaally delicious.
Cream the butter and sugars together until airy and light in color, about 2-3 minutes in a stand mixer.
Add the room temperature egg, milk, and vanilla until just combined.
Sift together flour, corn starch, and salt.
Add flour mixture to butter mixture in 3 installments, allowing the flour to almost fully-mix in before adding the next installment.
Bring dough together into a ball, and place on a floured cool surface.
Roll Out and Cut the Dough
Take ⅓ of the dough and roll it out on the floured surface to be about ¼ of an inch thick. If dough is too sticky, add a bit of flour at a time to the rolling surface and to the top of the dough to allow for easier rolling.
Use cookie cutters to cut the dough into whatever shape desired. Cut as many as you can from the dough and place on a nonstick cookie sheet.
Once you can no longer fit any cutouts in the dough, regather the dough together, re-roll, and re-cut.
Repeat with the remaining dough until there isn't any dough left.
Bake
Bake the cookies at 350 for about 8-10 minutes. The cookies should look set (e.g., not shiny), but should not be browned around the edges.
Remove the cookies from the oven and allow to cool completely. Frost with my royal icing recipe, or whatever icing you prefer.
