Listen, I know, I KNOW I’m going to be eaten alive for this but it’s the truth and I cannot lie… I ate cake mix powder as a kid. And it was wonderful. Yes, I’m talking the actual powder. I’d dump it into the bowl and if there was a clump I’d carefully, oh so delicately lift it up and eat it! It was so good! lol! How could I not make something cake mix flavor as an adult?
