Preheat the oven to 350 degrees F.
Line a cookie sheet with parchment paper.
In a medium to large bowl, add the cocoa powder, sugar, butter, and oil. Mix well to combine.
Add the egg, vanilla extract, and peppermint extract, and mix until well combined.
Add the flour, baking powder, and salt, mixing them well into the dough.
Add the Andes mint baking chips and fold in.
Using 1-2 tablespoon cookie scoop, scoop the dough, roll each dough ball until smooth, and place onto prepared baking sheet.
Bake in the preheated oven for 9-10 minutes - they will still be soft but will set up once they cool. Don't overbake!
Cool on baking sheet for about 10 minutes and then transfer to a cooling rack to cool completely.
Enjoy!
