  • Like the recipe but don’t care for red velvet? That is what is great about using a boxed cake mix as a base. You can use whatever cake mix flavor you love. All the cake mix flavors will work with this!
  • The white chocolate chips can be substituted for other flavors or you can just not add in any chocolate chips at all.
  • If you don’t enjoy a thick frosting, just cut the frosting recipe in half.

    I made this treat for Christmas to give as one of several other treats to neighbors. It was delicious. Will definitely make again. Thanks for the post!

  2. I’m not much of a baker so this recipe is much appreciated. I have a lactose intolerant grandson so wondering if I can use dairy free milk for frosting? Thanks!

    I am very puzzled about the recipe. I followed your recipe to the “t”, but without the cup of water that the box mix called for, it was so stiff that I could never have poured it into the 8×8 pan. So, I added 1 cup of water; that was much better. The cake tastes just fine, but I would like to make it again in the future, and I wish to do it correctly per recipe. Also, do you have a preference for the grand of Red Cake Mix? Please advise.

    I’m not much of a baker. I can cook, but baking is totally different language for me. So, thank you for using a cake box to make this recipe. Makes my life a lot easier. 🙂
