Preheat oven to 350 degrees.
In a large bowl, mix softened butter, sugar, brown sugar, peanut butter, eggs, and vanilla. Add soda, salt, and flour. Fold in chocolate chips.
Using an ice cream scoop, place 6 scoops of dough on an ungreased cookie sheet. Use your hand and slightly flatten each scoop of dough. (These are big cookies.)
Bake each batch for 12 minutes.
Remove cookies from oven and lightly press 8 cut-up pieces of Reese’s® peanut butter cups over the top of each cookie. Return cookies to oven for 2 more minutes.
Cool on baking sheet for 2 minutes before placing on cooling rack.
