Keto Lemon Cake with Syrup

This moist Keto Lemon Cake is soaked in a vibrant and tangy lemon syrup, making it Keto heaven.

It is higher in carbs being a baked good, so it is important to enjoy in moderation or around a lower carb day.

Using cardamom and ginger gives it a lovely floral undertone that matches beautifully with the tartness of lemon.




Keto Lemon Cake with Syrup


I once read an interview with a number of famous chefs, where they were asked what would be the one ingredient they could not live with out.

Every single one of them said lemons, and I completely understand.

Sweet or savoury, the acidity of lemons is to die for and can balance just about any dish.

Using 3 whole lemons in this Keto Lemon Cake ensures it packs a citrus punch. My mouth is watering just looking at it again.

I’m sure my husband won’t object if I make it again. He tried to convince me the flavours weren’t balanced just so I would make it again, I disagreed though!

If you are cooking anything – from cake to curry, and it just needs a little more kick, squeeze in a little lemon.

The almond meal you use is important here. You want a fine, blanched almond flour (ie. not with the brown bits in it!) to get a fluffy cake.

It isn’t fluffy like a sponge but the texture is amazing.

This recipe came about after craving some Greek Karidopita, which is a spiced walnut cake with a super sweet syrup.

So not keto, but I was craving that moist texture and tangy taste so this Keto Lemon Cake was born.

I think this cake is perfect for entertaining, because you can make it in advance and serve it cold with some cream.

The punchy lemon flavour is really great after a hearty meal and is bound to wow your guests.

It may not look like the prettiest cake (or maybe I’m not good at making pretty cakes?) but the flavour makes up for it.


Enjoy! x
