Cream the butter with the sugars. Add the vanilla and egg and mix in.
Add in the flour, cocoa, baking soda and salt. Stir until combined.
Lastly add in the Andes, mini's and chocolate chips then drop by spoonfuls on a baking sheet.
Bake the cookies for 10-12 minutes depending how big you make them. Leave them on the baking sheet for 5 minutes before transferring to a cooling rack.
Store in an airtight container.
Notes
I found Andes baking chips in our bulk section at the grocery store.
