Preheat your oven to 350 degrees Fahrenheit. Line a 9 x 9 inch cake pan with parchment paper, ensuring it hangs over the edges for easy removal later.
In a microwave-safe bowl, combine 1 cup of dark chocolate chips with 10 tablespoons of butter. Heat in the microwave for one minute and stir until smooth; if necessary, heat for an additional 20 seconds.
Using a stand mixer, beat three room-temperature eggs on high speed until frothy—this should take about 2-3 minutes. Gradually add in the melted chocolate mixture while continuing to beat until fully combined.
To your wet mixture, add in flour, cocoa powder, baking powder, kosher salt, and remaining chocolate chips; mix until just combined without overmixing.
Spread the brownie batter evenly into your prepared pan using a spatula. Bake in your preheated oven for 25-30 minutes or until a toothpick comes out with just a few moist crumbs attached.
Once cooled, cut your brownies into squares and chill them in the freezer for about 15 minutes before dipping them in melted chocolate mixed with coconut oil for that perfect coating finish! Once coated and set in the fridge again, decorate with bandage icing made from powdered sugar and cream before adding candy eyes for that spooky touch!
