A moist and zingy lemon cake that’s made without flour, butter, eggs and oil. A naturally gluten free healthy cake sweetened purely with fruit.

This healthy cake doesn’t just taste great but it’s full of healthy fats and protein. Two slices of my lemon cake recipe even has a portion of fruit! A foolproof easy cake recipe that’s full of goodness.

a bit of this healthy lemon cake recipe. the lemon rind is used to add a really zesty lemon flavour

As you’re using the rind for this lemon cake recipe make sure to use unwaxed and untreated lemons. I tend to buy organic lemons as they are untreated but be warned unlike normal lemons they don’t last long at all, so buy them and use within a day.

If you can’t get organic lemons check the label to see if they have been treated, in the EU they illegally need to say if the lemons have had any coatings or treatments applied.

gluten free vegan lemon cake recipe that is foolproof and anyone can make. Full of healthy ingredients and sweetened only with fruit.

The flaxseed in this gluten-free lemon cake is the vegan replacement for eggs. When added to water it becomes gel like and once baked and cooled helps it set – as well as adds nutrition.

You can use brown flaxseed (linseed is the same as flax) but purely for aesthetic reasons I prefer to use golden to make a more, well golden cake. Also chia seeds can be used if ground, but again they do affect the aesthetics, but not the taste!

a stack of my lemon cake that's made without any dairy or oils. All the fats come from almonds and flaxseed.

I add a lot of lemon to this cake, it’s the kind of cake that’s very moist and makes a wonderful sound as you pull it away from the paper.

It tastes very much like a lemon drizzle cake but hasn’t been doused in a liberal amount of sugar syrup so your body will thank you.

Sultana and lemon juice is blended together to make a sweet and zesty syrup that's high in fibre without any refined sugar

If you don’t have ground almonds you could try to blend your own almonds, but you need to blend them enough so it’s a flour but not too much to make almond butter. It can be a bit fiddly doing this as sifting and several batches are optimal.

Luckily ground almonds and almond flour is now available everywhere including the limited range budget supermarkets.

anyone even a child can make this gluten free and healthy lemon cake as after blending all that's needed is some stiring.

Often in life I use limes in place of lemons but for some unknown reason lemon cake is vastly superior to lime cake, at least for me!

As this vegan lemon cake doesn’t contain any eggs you can taste it before baking to check the sweetness or lemon-ness. Sometimes I add a tablespoon or two of coconut sugar if I’m making for someone that’s into more “normal” cakes.

vegan lemon cake that's made without eggs as flax seeds are used as an egg substitution. flax seeds are high in heart healthy fats and omega 3 fatty acids.

  8. Spread out the vegan and gluten free lemon cake mixture into the pan.
  9. Bake for 30 about minutes in the middle of your oven and take out just as the top gets some colour

In the video I use greaseproof paper to line a pan for oil free cooking. Some prefer to use spray oil and others prefer to use silicone bakeware, all work well.

      Yes you can, but do mill it dry before adding (unless already ground). The colour is a bit affected but still tastes great πŸ™‚

      Hi there, afriad not – oat flour doesn’t have much fat so although it would work it would end up being a bit different. Do try it and report back though πŸ™‚

      Really sorry I think they’re pretty important in this recipe, a ground seed like sunflower might work but be a bit more earthy and you’d have to mill it yourself
