Decadent {Low Fat} Diet Coke Cake!!!!

Oh. Wow. Never would I have thought that a Diet Soda + Cake Mix = a decadent, yet low fat CAKE! Consider my mind blown. Just by nixing the eggs and oil, you deduct many calories from the cake. But who would have thought that adding a can of my favorite diet soda to it instead of the eggs and oil would make such a divine, diet-friendly dessert! Not me!!!!! Gotta be honest. I was truly skeptical. I decided I would give it a go but not have high expectations. And honestly, it was really delicious!

I decided to make it while my older boys were at baseball practice (so they wouldn’t see what I was making) and then give them a piece after dinner and get their feedback. They. Loved. It. When I told them it had a can of Diet Coke in it, their jaws hit the floor! You can use any kind of diet soda and any cake mix too – I’m already thinking of the yummy combos! Strawberry cake mix + orange soda, funfetti cake + lemon-lime soda, I mean seriously the list goes on and on! I’m a chocolate freak and currently trying to maintain a healthier diet, so this really hit the spot!

Here are your ingredients:

Plus I added 2 egg whites to make it a little fluffier.

  • 1 dry box cake mix, any flavor
  • 10 oz. diet soda, any flavor
  • 2 egg whites
  • cooking spray

Preheat oven according to box directions. Spray 9×13 pan with cooking spray.

Beat cake mix, diet soda and egg whites in a large bowl for 2 minutes. Pour mixture into pan.

Decrease cooking time by 5 minutes from what the box says. A toothpick inserted in the middle of the cake will come out clean when it is finished. Let cool before cutting into squares. Serve with fat free whipped cream if desired! Yum!

    Just finished making two of these. Hubby said we needed one to sample before making one to take with us to a party tomorrow. It passed the hubby and four year old grandson test with flying colors! Yummy!
