If you’re looking for an easy cake recipe, you have to try my sugar free keto chocolate ricotta cake.

This cake is moist and delicious, yet sugar free, grain free, gluten free and very low carb, making it a perfect ketogenic dessert.

It is one of the easiest cakes I’ve ever made, with all ingredients going into one bowl, so there is even less washing up to do afterwards.

Having tried numerous versions using different flours, the winner, hands down, was the one I made with lupin flour.sugar free keto chocolate ricotta cake

So what is lupin?

Although it is often described as a grain, lupin is actually a bean, or better still, a seed, obtained from the lupin plant. The plant grows in abundance all over the Mediterranean region and is wildly cultivated for crop rotation as well as for the food industry.

If you ever visit Italy’s grocery stores, you will have no difficulty finding jars of yellow lupins preserved in brine, a bit like olives. Lupin beans have a waxy inedible coat that you discard before eating the soft middle part. You just put them in your mouth, break the husk and spit it out, leaving you to savour the pulp. Italians love munching on these. I am not too keen, to be honest, as I find these yellow lupins to be dry and bland in flavour. They are also expensive to buy and don’t last more then a few days once the jar is opened. Having said that, they are a very healthy snack: ask any old Italian lady and she will sing the praises of lupin for all sorts from curing gout to keeping headaches at bay.

The flour is obtained from the white, or sweet, lupin plant variety and is GMO free. It has a high content of protein and fiber, a very low Glyceaemic index and very few carbs, which is unusual for a flour derived from a legume. Before you rush to buy lupin flour, however, you need to consider that it is a legume of the same family as peanuts and soybeans, so if you have an allergy to these you may also have an allergy to lupin.

Where to find lupin flour

In the UK, you won’t find lupin flour in ordinary stores or even in health food shops. In fact, mention lupin flour and virtually everyone will say they’ve never heard of it. It is a real shame, because its health benefits are pretty amazing, it is inexpensive and it is very versatile in cooking.

Even my favourite shop in the world, Amazon UK, only has one seller for lupin flour, and the price tag is prohibitive.

My lupin flour comes from an  amazing online store in Luxembourg that sells an organic, GM free, yet inexpensive flour. You do have to pay for international courrier delivery, but if you buy several packs, as I do, the cost is negligible and your items will arrive within 2-3 days. N.B. I don’t have any affiliation with this company or receive any commission for promoting it. I just like the lupin flour they sell.sugar free keto chocolate ricotta cake
