Diet Coke Cupcakes with Cream Cheese Frosting

I’m not a big cake person but I’ve always heard from people trying to lighten up their diets that you can make really delicious cake using cake mix and diet soda. My mom ended up making some and it really did taste moist and delicious, so I decided to try it myself, as cupcakes. They turned out pretty well!

I decided to top them with frosting (who eats cupcakes without frosting?) and I found a yummy looking cream cheese frosting recipe on the Skinny Taste site. The frosting turned out pretty good, but I opted to replace the sugar in the recipe with Splenda to lighten it up even more and in the future I would just use the sugar or a blend of the two. The frosting definitely had that Splenda aftertaste to it. Otherwise the frosting was good, so I look forward to trying it again without the sugar substitute.


Diet Coke Cupcakes with Cream Cheese Frosting

Yield: 24 cupcakes


Diet Coke Cupcakes:

  • 1 box of cake mix – it can be any flavor, I used chocolate
  • 1 can of diet soda – I used Diet Coke but again, it can be any flavor
  • 2 egg whites

Cream Cheese Frosting:

  • 8 oz 1/3 fat cream cheese
  • 1 cup powdered sugar (I used Splenda but I recommend following the original recipe)
  • 1 tsp vanilla extract


  1. Preheat oven per directions on cake mix box
  2. Line cupcake pan with 24 cupcake liners or use cooking spray to lightly coat 24 spots
  3. Combine all ingredients in a large bowl and beat together until thoroughly mixed. Pour mixture into cupcake liners.
  4. Bake according to directions on cake mix box. Let cool completely before frosting.
  5. Combine all frosting ingredients in a bowl and beat with an  electric mixer until smooth. Top cupcakes with frosting.

    I have made diet soda cupcakes several times, but that frosting takes them to a whole new level! Even my diet-phobe husband liked them (!!!). I did a little write up on my blog if you want to check it out
    Love your blog:)

    Can you make these with Coke Zero or should it be Diet coke??

      Can you believe I’ve never even tried Coke Zero? I should get some. I’m sure it would be fine to use that instead. Hope you like the cupcakes!

    So, they’re 1 WW ppl using the powdered sugar? Or 1 ppl with the splenda? And you used standard cupcake pans?
