Preheat the oven to 350 degrees and line a baking sheet with parchment paper.
Pour the entire package of vanilla cake mix into the mixer and add the stick (1/2 cup) of room temperature salted butter, 2 eggs, and a cup of rolled oats. Mix thoroughly. Stir in 1 cup of chocolate chips.
Use a regular size spoon and scoop onto a baking sheet. Make sure to leave 1/2" of room between the cookies so they don't bake together. Place the baking sheet on the middle rack of the oven and bake for 10-12 minutes. The cookies are done with the edges look slightly brown.
Remove from the oven and cool on a cooling rack. Repeat until all 24 cookies are baked.
