Some idiot at work brought this in for his birthday. No-one really likes him that much but luckily we all loved his cake.

Sorry forgot to add, the supercook baking powder is gluten free but is not actually marketed as "gluten free baking powder". Its generally much cheaper than those that you find in the GF aisle.

nsrdm03 Some baking powders contain wheat flour as a filler so are not gluten free.

sorry for asking a stupid question, but should the mashed potato be done with butter and milk, or just potato? im not very confident with cooking! thanks for your help!

hi, I'm left wondering why you would specifically use gluten free baking powder? Do other baking powders have gluten in them or is it that Gluten free baking powder is more suited to gluten free flower?

Cake turned out great, but because I had no almonds I used sweetened desicated coconut... an unusual combanation, but tasted great! ( very very moist cake! ... yum!)

Didn't mash the potato finely enough and had lumps of potato through it - disgusting! It looked lovely, but the taste was NOT good!

A super easy and fantastic tasting gluten free cake!

made this but found it a very wet texture...would be better as a pudding served with ice cream than a cake. Flavour was wonderful though. I bought a potato ricer and now wonder how I managed with out one all these years!!

I'm planing to make this cake for Boxing Day, as my Mum is wheat intolerant. Has anyone made this in advance and frozen it? Was it OK? Thanks.

What a stunner. I made this as a surprise for a celiac friend - once following the original recipe, and once adapted a little to make a vanilla birthday cake - and both times she was so happy and touched that she almost cried. The time I made the lemon version was for a coffee morning, and it was a massive hit with everyone else as well - no one guessed the secret ingredient, and several people said it was the best lemon drizzle they'd ever had, gluten-free or not!

I didn't have a potato ricer but mashed the potato well and left it overnight in the fridge. Next day I mashed the potato again with a fork to break up any lumps. Only had 140g of ground almonds so made up the rest with brown rice flour. The result was lovely - had some warm as I made it in the evening and couldn't wait for the next day to try it!! My 9 year old loves it but for me the only snag is the calories. I wonder if it would still be as yummy if I substituted the almonds for rice flour?? I'll try it and see!

I followed this recipe by the book, and it was a flop (quite literally). I don't know what went wrong but the outside was fine, the middle was still like mash potato, and i could taste the mashed potato. I won't be trying this again anytime soon, unless anyone can suggest what may have gone wrong.

I tried this as we were visiting family and my sister in law follows a gluten-free diet.Everyone looked a bit shocked when I said it had mashed potatoe in it but it was really tasty-you would never know!!It was enjoyed by all!!!

I would like to make this as a birthday cake for a colleague, and wondered about putting a philadephia, icing sugar and lemon topping on it (similar to whats usually on a carrot cake). Would this still make it gluten free and would it work together?

Excellent recipe. My sister passed this recipe on to me as I am gluten intolerant. I've made it again and again for the family and it's such a hit that my mum made it as the top layer of my wedding cake!

Made this cake for my daughter-in-law who is allergic to gluten, she said it was delicious like eating real cake!

Don't be put off by the potatoes-it works! My mum's allergic to wheat so it went down especially well with her

My 4 year old daughter , who is coeliac loved it - wanted it for breakfast!! No-one could believe it was made from mash tatties.

made this on friday as my coeliac sister in law ( along with the rest of the family) were coming for tea on saturday; also made carrot and almond cake ( vegetarian good food april/ may 1993) which only has 2 tablespoons of flour in it, which is ok for her. Both cakes gorgeous and she thought i had bought them! My mash hating brother was none the wiser. The mixture did look a little odd, like it had curdled, when i added the potato.
