Preheat the oven to 400℉ and line a baking sheet with parchment paper.
In the bowl of a stand mixer (or use a mixing bowl and electric hand mixer), beat the butter and sugar until pale yellow and creamy.
Add egg, milk and vanilla extract and mix on medium speed until well combined. Add food coloring, if using.
Stir in flour and baking powder until just combined. Do not over mix the dough.
On a floured surface, roll the dough to a thickness of ¼ - ⅙-inch. I recommend using this rolling pin for perfectly rolled cookies.
Use your favorite cookie cutter shapes to cut out the dough. Use a thin metal spatula to transfer cookies to the prepared baking sheet. Sprinkle with colored sugar or sprinkles, if desired.
Bake in preheated oven for 5-8 minutes, until lightly browned on edges.
Helpful Tip: Add a piece of scrap dough to your cookie sheet. You can lift this scrap piece to check if the bottom of your cookies is golden brown rather than damaging one of your perfect cut out cookies!
Cool the cookies on the baking sheet for 3-4 minutes, until they’re firm, then move to a wire cooling rack to finish cooling.
Store in an airtight container for up to 2 weeks for freshness!
Note: Once you roll the dough/put your cookies on the sheet, gather your scraps, form into a ball. Roll it out again and cut out more sugar cookies. Don’t waste!
