Preheat oven to 350. Line or spray baking sheets. In a medium bowl combine flour, baking soda and salt. In mixer, beat butter, peanut butter, brown sugar, and sugar on medium-high speed until well combined, about 2 minutes.

Add eggs, milk, and vanilla and beat until combined. On low speed gradually add flour mixture and beat until just combined. Add chocolate chips, peanut butter chips, and Reese's Pieces and beat until combined. May do by hand with a spatula if mixer isn't strong enough.

Roll dough into 1/4-cup balls and place on baking sheets. Flatten balls into 1/2-inch thick disks. If desired, press extra chips onto top of dough and sprinkle with Turbinado sugar. Bake 12-15 minutes, or until cookies are light golden at edges. Do not overbake. Cool completely and store in an airtight container.
