These Cookies 'n Cream Cookies are perfectly sweet, a bit salty, crunchy, and moist all at the same time! They stay chewy soft for days, and are a crowd favorite!
Preheat oven to 350F with rack on lower middle position. Line large baking sheet with parchment paper.
Using paddle attachment of stand mixer (or hand mixer), mix butter and sugar until fluffy and fully combined. Add egg and vanilla, and mix until incorporated.
In a separate large bowl, combine flour, baking soda, and salt. Whisk to combine.
Gently fold butter mixture and flour mixture together, using rubber spatula. When dough is fully combined, gently fold in broken cookie pieces and white/chocolate chips. If needed, chill until dough can be easily shaped.
Form walnut sized balls out of dough, flatten slightly (these don't spread too much), and place onto parchment-lined baking sheet.
Bake 8 minutes or until edges look done. Centers will still seem underdone, but they set up nicely upon cooling. Let cool on baking sheet for a few minutes, and then transfer on wire rack to complete cooling.
