If you’re mouth is watering for a lemony cake, you’re in good company. It seems that lemon cake is beloved by just about everyone. In our house, this keto naked lemon cake was such a hit, we had to quick freeze slices of it because it was hard to stop eating!

This is special occasion cake, and one I made for mother’s day and our 20th Wedding Anniversary Party.

You need to know how hard I worked on getting this cake right. On Saturday morning I squeezed 8 lemons, measured out all my ingredients and the cake was a big flop. Not just a flop. A disaster, because it had to be tossed.

Here’s what happened when making this Keto Naked Lemon Cake

I thought I could take a different keto cake recipe and turn it into lemon cake, but it didn’t get any structure at all and crumbled, not in a good way. There was no saving it, even for snacks.

While I had used only coconut flour, I realized that my success with citrus cakes like this orange cake was based on almond flour and this very popular lemon snack cake was also based on almond flour, so I immediately went back to the store and bought more lemons and started over and did some thinking. Obviously the coconut flour cake could not handle all that lemon juice. Every baking failure tells me something!

Bake Naked Lemon Cakes to a Golden Brown

When I saw how the three cakes baked to a beautiful golden, I knew I had the right lemon cake recipe.

The batter will be thick. Don’t worry about that. Smooth it out with an off-set spatula.

I hear over and over again about the fears of baking because of the exactness of recipes. I relish a cake baking challenge, because it’s like going on a culinary scientific adventure. Every single failure teaches me something and it’s usually the failures that bring amazing success.

No matter how many times I bake with alternative flavors (a few times a week) there is always something to learn. For a while now I have been using avocado oil (which I love),  but I was out of oil and forced to use butter in this recipe. I discovered something. Butter is better, at least in this lemon cake.

It brings out more flavor, even if it makes the cake a little more dense. Since this is a triple layer cake, dense works out, as it’s sandwiched between lemon cream cheese frosting.

Decorate with lemon peels, blueberries, and if you like fresh lemon thyme.

Keto Naked Lemon Cake

Naked cakes are my favorite cake to make. You get to have more frosting in each slice, and they are so pretty.

What is a naked cake?

Basically, most naked cakes do not have icing or frosting on the sides, and are often triple layered. I lean towards them, because they are beautiful and use less frosting (or you can stuff the frosting inside the layers, which is marvelous.

What do I need to make this Keto Naked Naked Cake?

This naked cake requires three 6-inch pans. I love the idea of not having to frost the sides. The key to having good sides is make sure you cool your cakes well, and freezing them before you frost them. A broken piece of cake does not look good naked. By the way, if you don’t have six inch pans, you can use this recipe to make a 9 inch layer cake.

How many lemons make a cup of lemon juice?

Typically, it takes 8 large lemons to make a cup of fresh lemon juice. The zest is really important as almond flour is challenging to flavor.

Can you buy bottled lemon juice for this recipe?

You can, but it won’t be as lemony. If you do, at least use one fresh lemon with all the zest..

Why did you mix coconut flour with almond flour?

Using both improves structure.

What is Swerve? 

Swerve is powdered erythritol and I talk about it extensively here.

Why use xanthan gum?

Xanthan gum adds structure as alternative flours lack gluten and tend to fall apart. It’s pricy but lasts a long time because you don’t use much per recipe.

How many servings are in this keto naked lemon cake?

This is a very rich cake and can be cut into 16 servings, which yield 6 net carbs.
