Preheat oven to 350°. Line cookie sheets with parchment or silpat liners.

In medium bowl, whisk together flour, cocoa, baking soda, and salt.

In a large bowl, cream together the butter and sugars until light and fluffy. Add eggs one at a time. Add vanilla and mix until well blended. Add flour mixture and mix on low speed just until blended. Stir in chocolate chips and peanuts.

Using a small cookie scoop, drop by rounded scoops on to cookie sheets.

Cut a Snickers Baking Bites into three pieces and press into the top of each scoop.

Bake for 8 minutes, until edges are set, but still soft in center. Let cookies cool on the cookie tray for five minutes. Remove cookies to a wire rack to cool.
