Preheat the oven to 350 degrees.
Add the cake mix, oil, and eggs to a large bowl and stir until completely combined.
Stir in the baking chunks.
Line a baking sheet with parchment paper (optional for easier cleanup).
Use a cookie scoop to gather dough, then drop onto a baking sheet, spacing each scoop 3 inches apart.
Transfer the baking sheet to the oven, and bake for 10 minutes.
Remove from the oven, and set the baking sheet on a cooling rack for 2 minutes, then transfer cookies to the cooling rack.
