Step 1

To the bowl of a stand mixer fitted with the paddle attachment (or large mixing bowl and electric mixer) combine the butter, sugars, vanilla, and beat on medium-high speed until creamed and well combined, about 4 minutes.

Step 2

Stop, scrape down the sides of the bowl, and add the flour, baking soda, optional salt, and beat on low speed until just combined, about 1 minute.

Step 3

Stop, scrape down the sides of the bowl, and add the white chocolate chips, sprinkles, and beat on low speed until just combined, about 30 seconds. If your dough seems dry or crumbly, add milk or cream, 1 tablespoon at a time, until dough comes together. Conversely, if your dough seems too wet, add flour 1 tablespoon at a time until dough comes together.

Step 4

Using a 2-inch cookie scoop or your hands, form approximately 13 equal-sized mounds of dough and roll into balls. Serve immediately. Cookie dough can be stored in an airtight container in the refrigerator for at least 1 month, or in the freezer for up to 6 months.
