Marvellous looking cake isn’t it! Moist, buttery, my mouth’s watering just looking at that little bubble of lemon loveliness drizzling down the side. If I tell you this cake is made without any flour will you believe me?
Oh you do? You’re waiting for the BUT about how it tastes though.
Well, drum roll please…. no ifs, no buts, no maybes. This cake really tastes as good as it looks. Double helpings all round proved that! It’s the perfect choice for anyone who usually has to pass on the delights of baked goodies. Like 4 year old coeliac Megan who can now have her cake and eat it.
The best gluten free cake I ever made rejected wheat-free flours in favour of ground nuts (mmm cue drooly memories of Chocolate and Orange cake). This lemon drizzle cake demands the same but with an added twist. Did you notice the hidden extra in the mixing bowl?
I’ve been wanting to use mashed potato in a pud ever since I visited the Ministry of Food exhibition at the Imperial War Museum. I doubt a wartime version of this cake would have been as tasty minus the lemons and with rationed amounts of sugar and butter. I’m willing to find out though and feel re-inspired to have another thumb through my ‘Thrifty wartime ways to feed your family‘ cook book.
to make gluten-free lemon drizzle cake
200g butter, softened
200g sugar
4 eggs
175g ground almonds (replace with polenta or wheat-free flour for a nut free version)
250g cold mashed potato
zest of 3 lemons
2tsp gluten free baking powder (Supercook does one)
For the drizzle: juice of one lemon, 4 tbsp sugar
- Heat oven to 180C/fan 160C/gas 4.
- Butter and line a deep, 20cm round cake tin (serves 8-10)
- 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.
- 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 minutes 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.
- Store in an airtight container in the fridge and eat within 3 days (this won’t be difficult!). In my experience the moistness and greater quantity of eggs in flour-less cakes means they don’t keep as well (things start to grow!)
* you may have noticed I drizzled the bottom of my cake. Two reasons for this:
1) I didn’t want to risk the cake collapsing by trying to flip it over
2) the top was so beautifully crusted I thought it would soak in better bottom up.
This is what you can expect it to look like fresh from the oven.

Nip it in the bud 
What a fabulous recipe! I will have to share that with my sister who has many coeliac friends who she bakes goodies for. Thanks Nic!
Yum-o!
Blimey that does look good.
I haven’t tried baking cakes with mashed potaoe (yet) as it’s eggs that gets my little one – though I did try an egg free lemon drizzle cake – it came out flat!
Emjoy the rest of the day,

Hi Nic, I take it you will keep a piece for your mum
when you see her this week won’t you?
What a great recipe! I am sure megan would have been excited to have some cake
love mashed potato in baking – I’ve tried potato bread, chocolate cake, pizza bases but my favourite would have to be the boston bun! My mum even tried a GF pastry recently which had mashed potato – she loved it
Reading this recipe and looking at your pictures has got my mouth watering and I have only just had my breakfast.
Looks gooooooood! I had a colleague who was gluten-intolerant at my last school and often made cakes which used ground almonds in place of the flour. I have never tried mashed potato in one though!
Joanna – a pleasure. When you find a recipe this good you just have to share it!
Tom – couldn’t agree more 😉
Nina – that’s a bind not being able to eat eggs. Will keep little Boo in mind if I come across any suitable cake recipes. At least there are lots of biscuity/flapjack alternatives for her
Dad – ‘fraid not. This is the cake you missed out on at Nan’s last month when everyone had two slices! (always posting a few weeks/months behind!)
Johanna – I’ll be trawling your archive for sure. Intrigued by the potato pizza base – have been dabbling with the idea of using polenta.
Simon – I know the feeling! You’d get on well with G who started the day with apple pie for breakfast
Norm – I shall definitely be doing further experiments with my mash. Perhaps even with my peruvian purples!
ID would love this, not sure what he woudl think of the mashed potato in it though. Well I will just have to try it out someday.
don’t tell him it’s there and he’ll never know. None of my tasters could guess what the secret ingredient was!
What a lovely lemon drizzle cake. The mashed potato must have made it lovely and moist too.
thanks, it did. I used floury red skinned potatoes from the allotment – they broke down beautifully in the water and needed hardly any mashing
Looks delicious, I must try it, I love lemon flavour and also fancy trying the mashed potato idea.
reckon it would work well with all sorts of combinations :o)
Tracy made the lemon drizzle cake for Megan and Olivia’s Christening yesterday and it really was delicious. Nobody guessed the secret ingredient!
Mel – glad to hear it :o)
Now just think how this would have looked if you’d used the Peruvians. Sounds like a fantastic cake – really moist and delicious.
Purple cake is definitely next on my list (still not loving the dry texture of Peruvians on their own). I wonder if the lemon flavour with a non-yellow coloured cake will be too much of a mind bend?
Cake in oven now! Can I freeze when cold?
Hi Gillie, I hope you were pleased with how it turned out. re. freezing, I have no idea I’m afraid – ours was eaten so quickly it wasn’t something I even had to consider. All I would say is that as it’s so moist I’d be a bit wary of freezing as I’m not sure if it would be soggy when it defrosted? that’s just me though as I’ve never been very successful at freezing things and being happy with the thawed result.

[…] Cream the butter, sugar and eggs and gradually mix in the flour. Add the spoonfuls of lemon curd. Spoon into 2 cake tins (or one if halving the recipe). Bake in a pre-heated oven at 180 degree C for approx 25-40 mins depending on how deep your cake tin is. I mostly guess the time but you’ll know it’s ready when a fork poked into the cake comes out clean. Turn your cake out onto a wire rack and while it cools mix up some butter spread and icing sugar for the filling. Mixing in some lemon juice or a teaspoon of lemon curd will make it lovely and zesty. Drizzle a little lemon icing on top and enjoy with your favourite cup of tea. If you need to cater for a gluten free friend have no fear I have that covered too in my blog post making gluten free lemon cake […]
