Melt the chocolate in the microwave. Heat in 20-30 second intervals, stirring after each interval until the chocolate is fully melted. Then set the chocolate aside to cool some so it doesn’t cook the eggs in the cookie batter.
In a separate bowl, stir together the dry ingredients: flour, cocoa powder, baking powder and salt.
Then in a large bowl, beat together the butter and both of the sugar together with a stand up mixer or a hand held mixer. Then add in the eggs and vanilla extract. Mix these ingredients together on high speed until the mixture is smooth and creamy. Scrape down the sides of the bowl. Then pour in the cooled melted chocolate and beat for 2-3 minutes until the chocolate is combined.
Slow add the dry ingredients into the butter mixture. Mix on a low speed slowly just until the ingredients are just combined. Be careful to not over mix the ingredients.
Divide the dough into 12 equal portions (approximately 1/2 cup each) and roll them into balls. Then flatten out the balls slightly and place them on a baking sheet (only 6 cookies per tray based on the size).
Bake for 14-16 minutes until the edges of the cookies are set and the cookies are crackly around the tops of the cookies.
While the cookies are baking, stir together the peanut butter and powdered sugar until well combined. Divide this mixture into 12 even size balls, flatten them out to look like hockey pucks and refrigerate until the cookies are done.
Remove the cookies from the oven and use a spoon to create a small dip in the center of each cookie. Let the cookies cool on the baking sheet for 3 minutes. Add a peanut butter ball to the top of each cookie.
Then place the semi-sweet chocolate chips and oil of your choice in a microwave safe bowl. Heat in 20 second intervals, stirring after each interval until the chocolate is fully melted.
Spoon approximately 2 tsp of the melted chocolate on top of each cookie on the peanut butter portion of the cookie and let set so that the chocolate re-hardens.
Then the cookies are ready to enjoy!
