Step 2: Mix the dough. Using an electric mixer, beat the butter, sugars, vanilla, and salt on medium speed until smooth and creamy, about 3 minutes. Mix in the cooled flour on low speed until crumbly, then incorporate the cream and chocolate.
Step 3: Serve or store. Enjoy right away, refrigerate for up to 5 days, or freeze for up to 3 months. If frozen, thaw overnight in the refrigerator and let sit at room temperature for about 10 minutes before serving.
