Rainbow Bundt Cake (Doctored Cake Mix)- Recipes My Mom Gave Me

I'm not ashamed to admit that I love cake mixes.  In fact, I love all kinds of boxed mixes.  Brownie  mixes, pancake mixes, muffin mixes...you name it.

For this recipe, we are making a fun rainbow cake (great for St Patty's Day ☘), but, the additional ingredients we add to the cake mix can be used with any kind of cake you wish.

How to Make A Rainbow 🌈

  • First, make your batter.
  • Then, divide the plain batter equally into 6 bowls.
  • Tint each bowl a different color.  When you are done, you will have 1 bowl of red, 1 bowl of green and so on.
  • After generously greasing your pan, spoon the red batter onto the bottom of your pan. Go all the way around the pan,  Follow the same pattern with the remaining colors.
  • Don't mix your colors/batter!  Let them stay separate.
  • Bake your cake.

Recipe Notes

  • If you stick with a standard size box of dry cake mix, this will work with any flavor or brand.  You can use the batter for a sheet cake, cupcakes or  a layer cake.  Use the same baking times as directed on your box of cake mix.
  • Be sure to get instant pudding mix. After buying cook and serve many years ago, I always like to remind people that there is a difference.  Also, don't make the pudding.  You will just use the dry mix.


💡 Tips for Getting Your Cake Out of the Pan 

  • Generously grease your bundt pan.  If you have it, use a cooking spray with flour in it.  See recipe card for product suggestion/purchase.
  • Give your cake a chance to cool for 8-10 minutes, then, run a sharp knife along the edges and center of the pan.
  • Invert the cake onto a plate or platter that is larger than the cake and give it a chance to fall naturally.  If it's not cooperating, give the bottom of the pan a few good taps.
  • If your cake breaks a bit, no worries! You can always cover it up with the glaze.
