Line a baking tray with parchment paper or a silicone baking mat.
In a large bowl, combine the chocolate cake mix, baking chips, vegetable oil and eggs. Beat with an electric mixer for 2 minutes, until a cohesive dough forms with no dry patches.
Use a cookie scoop to portion out dough in 2 Tablespoon-sized pieces, onto the baking tray, about 3” apart.
Bake for 8-10 minutes, until cookies have puffed up and cracks have formed.
Remove the cookies from the oven and immediately place one unwrapped chocolate on each cookie.
Allow the chocolate to warm up for 3-5 minutes, then use an offset spatula to spread the melted chocolate over the cookies. Allow the melted chocolate to set before storing or serving.
