Is Lemon Cake Keto-Friendly?

Regular and traditional lemon cake is not keto because it contains sugar and other ingredients high in carbs that are not good for a keto diet.

But since I am a lemon lover, and I made a lot of lemon dessert keto recipes like keto lemon crudlemon pound cake, and lemon bars, I decided to try a keto version of this recipe as well. 

And I was surprised to see that it tastes even better than the traditional one.

Keto Lemon Cake Ingredients

You will love this recipe once it requires only some common basic ingredients you probably already have in your pantry. Here is a list of the ingredients:

Below you will find a list of the ingredient amounts for this recipe.

For The Cake Batter

  • Almond Flour – Use superfine, blanched almond flour to obtain the perfect texture for the cake layers.
  • Sweetener – feel free to use your favorite low-carb sweeteners such as monk fruit, erythritol, or allulose.
  • Baking Powder – helps the cake rinse and become super fluffy.
  • Eggs – use large room-temperature eggs to avoid that eggy smell and flavor.
  • Coconut Oil – helps the batter to be moist. You can also use the same amount of melted butter to avoid making a dairy-free version.
  • Lemon Extract – used to enhance that lemon flavor and taste.

For The Frosting

  • Cream Cheese – make sure you use softened cream cheese to ensure good mixing.
  • Lemon Juice – use freshly squeezed lemon juice for a great flavor.
  • Sweetener – use any low-carb sweetener as long as it is powdered to mix well into the frosting.

  • You can make homemade whipped cream and paste it into the cake in patterns.
  • You can decorate it with lemon slices and mint leaves to boost fresh colors.
  • Make some keto lemon curd and spread it on top of the cake for an intense lemon flavor.

I was going to try making the Keto cake, but it shows that it is 9net carbs which is pretty high. Was the fiber amount incorrect?

Some of the ingredients in this cake are higher in carbs, but I recalculated, and each slice of this keto lemon cake has ~5g net carbs. Feel free to use an online calculator to figure out the exact number of carbs using your specific ingredients.
