  1. You can unmold the cake and place it on a platter, if you like. I sometimes take this approach if I am going to serve it at home and in this case I usually (but not always) also frost the sides of the cake.
  2. If you are traveling with the cake, or simply taking a more homespun approach, leave the cooled cake in the pan and frost the top. I usually apply the buttercream with a large offset icing spatula, but you can use the back of a teaspoon or soupspoon. Simply cover the cake and make whirls and swirls to your heart’s desire. Add sprinkles while the buttercream is still soft and moist. I just sprinkle on with my fingers! Cake is ready to serve. Cake may be held at cool room temperature overnight. If you refrigerate it, it MUST be brought back to room temperature or the cake and buttercream will be too firm, and the textures will be unappealing.



FODMAP Information

Our recipes are based on Monash University and FODMAP Friendly science.

  • Butter: Both Monash University and FODMAP Friendly have lab tested butter. Monash states that a low FODMAP Green Light portion is 1 tablespoon or 19 g and also states that “butter is high in fat and does not contain carbohydrates (FODMAPs)”. FODMAP Friendly gives it a “Pass” at 1 tablespoon or 19 g. Both recommended serving sizes are presented as part of healthy eating guidelines, not as maximum FODMAP serving size. Fat can affect guy motility and trigger IBS symptoms in some people. Eat to your tolerance.
  • Sugar: Monash University and FODMAP Friendly have both lab tested white, granulated sugar. Monash states that a Green Light low FODMAP serving size of white sugar is 1/4 cup (50 g). FODMAP Friendly simply states that they have tested 1 tablespoon and that it is low FODMAP. Regular granulated white sugar is sucrose, which is a disaccharide made up of equal parts glucose and fructose. Sucrose is broken down and absorbed efficiently in the small intestine.

Please always refer to the Monash University & FODMAP Friendly smartphone apps for the most up-to-date lab tested information. As always, your tolerance is what counts; please eat accordingly. The ultimate goal of the low FODMAP diet is to eat as broadly as possible, without triggering symptoms, for the healthiest microbiome.
