After two years of making keto lemon cupcakes known as Lala Cakes in my keto home bakery, I  improved my cake this week. This means it’s even better than ever and it’s always been really good. A top seller and a fan favorite. I  can honestly call this the best keto lemon cake recipe anywhere.

This recipe for keto lemon cake will make 12 oversized cupcakes, or one 8 inch double layer cake. It’s topped off with a keto lemon cream cheese frosting that is creamy, lemony and amazing!

Keto Lemon Cake which is also paleo friendly and gluten free is made from a combination of almond flour and coconut flour. It’s very similar to my basic recipe for keto cake, except I leave out the sour cream.

While sour cream adds something to my vanilla and chocolate cake recipe, leaving it out improved the flavor of the lemon.

Best Technique for Preparing Best Keto Lemon Cake

I have an unconventional method for mixing cake batter, but I didn’t invent it. Its the technique Christina Tosi from the Milk Bar uses. Instead of starting with creaming butter and sugar, we start with the eggs and whip them frothy. Avocado Oil or melted butter is then slowly streamed in, followed by the liquid, followed by the mixed dry ingredients. The result is a much fluffier cake and this is especially important with a lemon cake which can go flat.

  • Mix all dry ingredients, lemon zest, including the sweetener. Set aside.
  • Using a kitchen aid type mixer or hand mixer, whip eggs five minutes until frothy.
  • Stream in oil or melted butter.
  • Follow with liquid (lemon juice).
  • Add dry ingredients. Gently mix.

It’s important to taste your batter. I always microwave a teaspoon of batter to make sure it’s lemony enough.

How to Make Keto Lemon Cream Cheese Frosting

I like to use a combination of cream cheese and butter. A good ratio is 12 ounces of cream cheese to 4 ounces of butter. I use 1/2 cup Swerve Confectioner’s sweetener to every four ounces of fat.

Make a Layer Cake or Individual Cakes

This is the cake I baked for a crowd this year for a friend’s birthday. People loved it. Swooned over it and wanted it again. The cake is fluffy and the lemon cream cheese frosting is so creamy and lemony. I offer this in my bakery in two ways: a celebration cake and Lala Cakes. Lala Cakes are individual mini cakes baked in paper tart cups. If you plan on doing a lot of baking I recommend these cups. They are sold in 200 pack, but so worth it.

My Favorite Sweetener for Best Keto Lemon Cake

My favorite choice for keto sweetener is Swerve, which comes in both granulated form and confectioner’s form.

Take this Keto Lemon Cake to the Next Level

By a sheer fluke I threw some left over lemon cream cheese frosting and put it on lemon blueberry muffins. Incredible balance of flavors. Add blueberries to your cake batter AFTER it has been put in the cake pan. This simple addition is addicting. Blueberries love lemon. Period.

Serve with some of this sugar-free blueberry compote.

Lemon Layer Cake

    This looks amazingly delicious!! Can I substitute by using regular sugar until I order Swerve sweetener at a later date?
