Lemon Potato Cake – gluten-free & low FODMAP

Lemon Potato Cake -gluten-free & low FODMAPMichael Pollan quote
This cake has been a eureka moment! It is moist, delicate and delicious. I have baked with many different vegetables as a base for sweet dishes including pumpkin, zucchini, white beans and avocado but I have never used potato. And yet it is such an obvious choice because it is a starch just like flour. I made absolutely sure I didn’t overcook it, and that lemon syrup took it over the top. This has to be my biggest low FODMAP triumph yet. I finished it off with a little icing made of icing sugar and lemon juice just to kick it up a notch.
This recipe has almond meal in it but I have kept it to a small amount because the Monash University, which researches the FODMAP diet, says we can only have less than 10 almonds at a time. I have already discovered this and so do limit them. I still find it amazing that everything that is considered healthy to eat can be suspect for us. It has been an interesting journey so far.

    What a clever idea to use potatoes in a cake! You are such a creative cook – I love the idea! And lemon is one of my favorite flavors, so I find this immensely appealing. Really a bummer that you need to limit your almonds, because almond flour is such good stuff. But you’re coping extremely well. Anyway, wonderful cake – thanks.

      There is definitely no potato flavour, only the moistness so it works well. It is a shame about the almonds but 10 is quite a lot of nuts, I guess.

    This is such a beautiful looking cake. I love how the lemon icing just dribbles down the sides of the cake. I don’t think I’ve ever cooked a cake with mashed potato but I have used pumpkin, carrot, zucchini etc so I should try this. I does look super-moist. Thanks for the offer of your book xx

      I’ve used all sorts of vegetables in my baking but potatoes hadn’t occurred to me until recently. Not sure why not. The cake is still really moist today which is unusual for gluten-free baking.

    Do you use potato flakes or real mashed potatoes. If real potatoes, do you use a particular kind, i.e. russet, yukon, red? Thanks

    • says

      Shari, I used real mashed potatoes. I have never used potato flakes before – didn’t even know they exist. I bought general purpose potatoes which are the best for mashing. Don’t use the more waxy ones because they don’t mash well. If you make it, you will love it.

    Potato starch or some other kind of starch is an essential of gluten-free baking but mashed potato is the unusual ingredient. Do try it.

    Hi there! So I have been browsing TONS of recipes because my niece has many allergies, gluten and nuts specifically and i love this recipe and was curious if there is any way the almond meal can be substituted? My niece hates chocolate (she cant have most anyways) and she loves lemon so I am hoping that maybe you have a few ideas that you wouldnt mind sharing! Thank you!

    • says

      Hi Erin,
      I have plenty of nut and chocolate-free recipes on my blog. My cookbook is gluten, grain, refined sugar, dairy and nut-free. Maybe your niece should have a look at it.

    Hello this is somewhat of off topic but I was wondering if blogs use WYSIWYG editors or if you have to manually code with HTML.
    I’m starting a blog soon but have no coding experience so I wanted to get guidance
    from someone with experience. Any help would be enormously appreciated!
