I made this gorgeous banana cake with lemon icing for my birthday. This low FODMAP cake has the sweetness from the bananas and tanginess from the lemons which makes it absolutely delicious! My friends definitely couldn’t tell it was low FODMAP, gluten and dairy free. As always I would recommend having one piece of cake at a time so you don’t have too much sugar at once.
FODMAP Note: Common bananas when they are firm (unripe - green or just yellow) are low FODMAP in 100g serves, however they become high FODMAP for fructans when ripe (yellow with brown spots).
When choosing bananas make sure you select common bananas and not sugar bananas. Then use the bananas when they are firm (green to just yellow) and then become high FODMAP when they are ripe (have brown spots).
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.
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.
Use a dairy free spread or olive oil spread instead of butter. Butter is considered low FODMAP.
