HACK: Add a ½ cup of oil + 2 eggs to turn any cake mix into cookie dough.
THE IDEA: Now, when I first saw this, I wondered if I were supposed to add the eggs and the oil in addition to the usual ingredients you're supposed to add to the mix. The answer is no. You just add the eggs and the oil to your dry mix, stir until well combined and scoop balls of it on a baking tray. The instructions (from Reddit) recommended 8–10 minutes in the oven, at 350°F. In my first batch, the cookies were pretty large (about 1/4 cup dough each) so they took longer around 12–13 minutes to cook. I made smaller scoops in my later batches and they took around 10 minutes to cook.
DID IT WORK?: Yup!THE RESULTS: The cake mix made about 15 cookies, and perhaps unsurprisingly, the cookies were very cakey. I like my cookies crispy on the edges and super fudgy in the middle and these were none of that — so I didn't even eat the whole batch. (Even after adding some sea salt on top, which complemented the chocolate well.)So yeah, this works and if you like cakey cookies, you'll probably like them. But these did not rock my world. ¯—Marie Telling
