A dear friend of mine graduated from university and I made him this gorgeous low FODMAP carrot cake to celebrate! Instead of using cream cheese for the orange lemon icing I made a beautiful butter icing instead. As I am completely dairy intolerant I used a dairy free spread, but if you are just on the low FODMAP diet you can use normal butter. This cake does contain quite a bit of sugar so make sure you only have one serve at a time.
Check that the dried cranberries are sweetened with sugar and not apple juice.
Buy a gluten free plain flour or gluten free all purpose flour. The one I used contains these ingredients: maize starch, rice flour, tapioca starch, rice bran, & guar gum. Avoid flour blends that contain soy flour, chickpea/besan/gram/garbanzo bean flour, lentil flour, coconut flour, amaranth flour, or lupin flour.
Make your lemon juice and lemon zest from fresh lemon.
Make your orange juice and orange zest from fresh oranges.
Most icing sugars (powdered sugar) are gluten free, however some do contain wheat starch. This means you should check that your icing/powdered sugar is gluten free.
Herbs and spices are naturally gluten free, however they can become contaminated during manufacturing processes. If you are highly sensitive to gluten, check the dried herbs and spices do not contain a warning for trace gluten. If you are just on the low FODMAP diet you do not need to worry about this.
If you are highly sensitive to gluten, check all packaged products, processed meat (like bacon), nuts, seeds and dried fruit do not contain a warning for trace gluten. If you are just on the low FODMAP diet you do not need to worry about this.
Use a dairy free spread or olive oil spread instead of butter. Butter is considered low FODMAP.
