In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium speed until smooth and creamy, about 30 seconds.
1 cup salted butter
Add the milk and vanilla and mix to combine.
3 tablespoons milk, 1 tablespoon vanilla extract
With the mixer on low, slowly add the flour and powdered sugar. Continue mixing just until a shaggy dough forms.
2 cups all-purpose flour, ½ cup powdered sugar
Gently fold the sprinkles into the cookie dough.
¼ cup rainbow sprinkles
Shape the dough into a disc and wrap it in plastic wrap.
Place the dough in the fridge to chill for 15 minutes.
While the dough chills, preheat your oven to 350°F. Line a baking sheet with parchment paper. Set aside.
Lightly flour your work surface and roll the cookie dough out to ¼-inch thick. Cut the dough out using your choice of cutter (I used a 2-inch round cutter) and place the dough on the prepared baking sheet. These cookies don’t spread much so you only need to place them about 1 inch apart.
Bake for 14-16 minutes, or until the cookies are just starting to turn golden brown on the bottom.
Allow the cookies to cool completely.
Notes
Sugar: You can use granulated sugar, but your cookies will come out more crispy and less soft. If using granulated sugar, you can decrease the amount of sugar by about 25% if desired because it is much sweeter than powdered.
Funfetti shortbread cookie dough can be made up to 1 week ahead and stored in the refrigerator until you're ready to bake it. It can also be stored in the freezer for up to 1 month. Allow the dough to soften at room temperature, then roll out, chill, and bake as directed.
These funfetti shortbread cookies are great for any occasion. You can make them festive for the holidays by using holiday-colored sprinkles, such as red and green for Christmas; black, orange, and purple for Halloween; red and pink for Valentine's Day; shades of green for Saint Patrick's Day; or red, white, and blue for the Fourth of July!
Storage: Store funfetti shortbread cookies in an airtight container at room temperature for up to 1 week, in the refrigerator for up to 10 days, or in the freezer for up to 1 month.
