Perfect Low-FODMAP Coconut Cake Recipe; Gluten-free, Dairy-free

Printer Friendly Version

This low-FODMAP Coconut Cake is absolute perfection. It is exactly what a coconut cake should be.  Light, fluffy cake layers subtly yet expertly balanced with the sweetness of low-FODMAP coconut cream all covered by velvety low-FODMAP frosting. The coconut shavings give the frosting texture and make it beautiful and fun.  But just wait for the taste…melt in your mouth delicious!

This low-FODMAP Coconut Cake recipe is the best you will ever enjoy.  It is moist, light and beautiful.  Plus, it incorporates real coconut milk in the cake, and plenty of shredded coconut in the layers, making it so natural and fresh tasting.

Your guests will never know this low-FODMAP Coconut Cake is gluten-free and IBS-friendly.  Top it with my low-FODMAP Cream Cheese frosting or low-FODMAP Ermine frosting (for dairy-free option).

    • Double recipe for layer cake as per instructions

      • 2/3 cup or 64 g is one low-FODMAP serving for coconut
      • If decorating the entire cake need about 2 cups
  • Vegetable shortening, for greasing

For low-FODMAP Coconut Cream Filling:

  • 3 large egg yolks
  • ¼ cup plus 2 tablespoons sugar
  • 3 tablespoons cornstarch or potato starch
  • 1/8 teaspoon salt
  • 1 and 1/2 cups low-FODMAP milk (such as almond milk for dairy-free or lactose-free milk)
  • 3/4 cup sweetened shredded coconut
  • ¾ teaspoon pure vanilla extract


  • Preheat oven to 350 F
  • Line 2 x 9 inch round cake pans with parchment and grease well
  • In large bowl of stand mixer with flat paddle, mix sugar and eggs on medium for 1 minute
  • In a second medium bowl, combine low-FODMAP flour, baking powder, and xanthan gum
  • In a large measuring cup, place oil, coconut milk, vanilla and coconut extracts and stir to combine
  • Add the flour mixture to the egg mixture on low-medium, alternating with the oil/coconut milk mixture until all are combined; do not overmix
  • Pour batter into the 2 pans
  • Place in center of oven and bake for about 35-40 min, until cake springs back from pan edges and center is springy when touched, tester in center should come out clean (ovens vary, so yours may take more/less time)
  • Cool cakes in pan for 5 minutes, then invert to a rack and cool completely
  • If desired- chill or freeze cakes prior to decorating; this step is recommended if you plan to cut your layers to create a 4 layer cake
  • Prepare your choice of low-FODMAP frosting; add coconut extract to frosting recipe if desired (see note above)
  • Prepare coconut cream filling while the cake is baking and chill at the same time as the cake

Directions for low-FODMAP Coconut Cream

  • Place egg yolks in a large bowl; whisk to combine; set bowl aside
  • Combine sugar, cornstarch, and salt in a saucepan
  • Gradually whisk in low-FODMAP milk
  • Cook, stirring, over medium heat until mixture thickens and comes to a boil, 10 to 12 minutes
  • Remove from heat
  • Whisk a few tablespoons of the hot milk mixture into the reserved egg yolks to temper yolks
  • Slowly pour warm yolks into the saucepan, stirring constantly
  • Cook slowly, stirring, over medium-low heat, until mixture begins to bubble, about 5 to 6 minutes
  • Remove from heat
  • Stir in shredded coconut and vanilla
  • Transfer filling to a medium mixing bowl, and cover with plastic wrap touching the surface so a skin doesn’t form
  • Chill until set, about 1-2 hours in refrigerator

When ready to frost and fill low-FODMAP Coconut Cake, remove from refrigerator or freezer:

  • If making a 4 layer cake, cut both of the layers in half
    • I used a cake cutter as well as a long serrated knife.  This is tricky so take your time 😉
  • If making a 2 layer cake, skip this step
  • Place the bottom base layer on cake plate, and place half the low-FODMAP coconut cream on this layer
      • This will be a thin layer, just visible to the eye in the photos .  You don’t want the low-FODMAP coconut cream to overpower the lightness of the cake
      • The low-FODMAP coconut cream blends beautifully with the cake and gives it a moist texture and wonderful flavor
  • Top with the second half of this cake and place the low-FODMAP Opera Cream/Ermine frosting or low-FODMAP Cream Cheese frosting as the middle
    • Don’t forget to add some coconut extract to your choice of low-FODMAP frosting as per above ingredients
    • The middle layer will be slightly thicker than the other 2 layers
  • Repeat with the next cake layer and place the low-FODMAP Coconut Cream on this layer
  • If making a 2 layer cake, spread the low-FODMAP Coconut cream in the middle
  • Top with the top layer of the cake and frost top and sides with low-FODMAP Opera Cream/Ermine frosting or low-FODMAP Cream Cheese frosting
  • Garnish cake with the shredded coconut
  • Chill until serving

Moist, light and so delicious.  I think this may be my favorite low-FODMAP Cake Recipe ever!
