Dazzling Low-FODMAP Rainbow Celebration Cake / White Wedding Cake; Gluten-free

Print Friendly Version

This low-FODMAP rainbow celebration cake is the most dazzling low-FODMAP treat you will ever have!

You can change it up:  use black and orange colors for Hallowe’en, add sprinkles instead for a low-FODMAP confetti birthday cake…so many choices!

Or just keep it plain white and enjoy at a wedding or other special occasion. It makes an ideal low-FODMAP White Wedding Cake.  Use my low-FODMAP White Buttercream Frosting for the perfect combination.

This low-FODMAP cake is gluten free and tastes fantastic.

  1. I made this cake for my niece’s 18th birthday. I used King Arthur 1:1 gf flour and dropped each color in the center of the color before, banging the pans to spread layer. I put the colors in opposite patterns between the two pans so the “rainbow” was reversed when you cut through. The icing was Amazing! My family couldn’t believe this was gf and low fodmaps. Delicious!

    1. Hi Alex,
      Wow that sounds amazing! So glad this was a success. Thank you for your comments 🙂
