Preheat the oven to 350 degrees and grab a lined baking tray.
Start by combing butter, sugars, vanilla and eggs in a bowl. Mix well and then sift in the cocoa powder mixing throughly to well combine.
Combine the flour and baking powder in a separate bowl and gradually add to the wet mixture. Don’t overmix!!
Fold in the chocolate chunks and chopped Oreo cookies at the very end.
Scoop 2 tbsp sized balls of dough onto the baking sheet. Bake for 10 minutes. Makes 12-15 cookies.
Once cooled, melt the remaining 1/4 cup of chocolate and drizzle over the cookies. I added a few more Oreo chunks at this point too cause why not!!
