  1. Heat oven to 180C/fan 160C/gas 4. Butter and line a deep, 20cm round cake tin. Beat the sugar and butter together until light and fluffy, then gradually add the egg, beating after each addition. Fold in the almonds, cold mashed potato, lemon zest and baking powder.

  2. Tip into the tin, level the top, then bake for 40-45 mins or until golden and a skewer inserted into the middle of the cake comes out clean. Turn out onto a wire rack after 10 mins cooling. Mix the granulated sugar and the lemon juice together, then spoon over the top of the cake, letting it drip down the sides. Let the cake cool completely before slicing.

This was delicious - such a refreshing change to find a simple tasty wheat free recipe! Instead of mashing the potatoes, I cooked them so they weren't completely falling apart, allowed to cool/rinsed them in cold water, then grated them into the mixture (no potato ricer!!) but this seemed to work perfectly - texture is lovely and moist, although as mentioned in other comments I think I may bake for slightly longer next time. covered it in raspberry jam and coconut - took me back to school dinners!!

Was VERY well received by my celiac friends and just won me first prize in show category 'cake for special dietary requirements'! So it must be good!

Followed the recipe as stated, but found it took quite a bit longer to cook (perhaps I was using a deeper cake tin), but still turned out brilliantly. Very delicious and moist. Took it into my son's primary school for his birthday as one of his classmates is gluten intolerant - seemed to be widely enjoyed by staff and pupils alike.

Bit dubious initially about using potato in a cake but it tastes fantastic. Will definitely make it again. All my friends wanted the recipe too!

Delicious, doesn't taste like gluten free at all. I served it to 9 people & there wasn't a crumb left on anyone's plate.
