Best Almond Flour Cake Recipe – Low Carb, Keto, Grain-free, Gluten-free, Sugar-free

I’m not a cake person. I’ll admit it. It’s the last dessert I would order in a restaurant; I pass up a slice of birthday cake with ease. I don’t know if its the sickenly sweet way that American’s do frosting, but cake is just a bit of a turn off for me. I find there are only a few exceptions to this rule:  upside down skillet cake, clafoutis (a French-style custard cake), or this Citrus Almond Ricotta Cake.

This keto-friendly cake is modeled after an almond olive oil cake I tried in Rome last year. It had this wonderful light citrus undertone with a moist texture. Since I was in Rome, you know, when in Rome, I ate the cake without reservations, but the recipe definitely had a few ingredients that wouldn’t fly here with my low carb lifestyle. This recipe recreation is, and don’t tell the chef from that osteria in Trastevere this, even better than what I remember. The addition of ricotta cheese adds a wonderful richness and overall oomph to the cake that wasn’t in the original. I also added grapefruit zest because, well, why not? I love the trio of citrus flavors in this cake.

If you told me this was grain-free and sugar-free, I’d never know. This is the kind of cake I can get behind. It combines all my favorite flavors into one with a light, moist result. With a little powdered erythritol and some slivered almonds, you can easily create a simple but elegant presentation for your guests. This cake is light enough to serve after a rich holiday meal, or perfect with a cup of coffee for breakfast or even afternoon tea. It’s versatile. It’s delicious. It’s one of only a few cakes that I can get excited about, and that says something.

Keto Citrus Cake Tips & Tricks

Extra-virgin olive oil in a cake? That sounds like it would taste funny. Yup, and nope. Extra virgin olive oil is fantastic in baking! You get a nice healthy dose of monounsaturated fats and antioxidants from using extra-virgin over regular olive oil. It’s light flavor easily incorporates into this recipe, mingling with the ingredients. I would not recommend olive oil since the stronger flavor may be a bit bitter and overpowering in this cake. Not all olive oils are created equal. You do not need to use a super pricey drizzling extra-virgin oil here, but do taste it. Look for light, buttery or fruity notes instead of a deep, intense peppery oil. 

No almond milk? No problem. You can use whole milk instead. Sometimes I forget to buy it. I’ve subbed out whole milk in this recipe with no issues. Totally works!

The edges of the cake are quite delicate, wait until completely cool to unmold. Don’t unmold the side of your springform pan until the cake is absolutely cool. The sides will easily tear or crack. I found out the hard way, of course.

Elevate this cake with simple toppings. A quick dusting of powdered erythritol and a sprinkle of slivered almonds is just enough to make this cake a show stopper.
