This unique lemon cake is light, airy and soft. The surface has a delicate, sweet crackly crust and underneath is a soft cake. This cake is just 4 ingredients and doesn’t require any butter, oil, milk or baking powder. It is perfect for serving at special events.

This is the cake I plan on making for a few upcoming holiday brunches and other events. It’s not like your typical cake but it is so unique and delicious. The surface has a delicate sweet shell that cracks when you cut in. Underneath the shell is a light and airy cake, similar to a sponge cake.

Ingredients

  • Eggs
  • Sugar
  • Flour
  • Lemon

Eggs: Eggs are used to create the structure for this cake. The eggs are beaten with the sugar until they are more than triple in volume. This method is used for some sponge cakes.

Sugar: This recipe uses regular granulated white sugar. It gives the cake sweetness.

Flour: This cake only needs regular all purpose flour. I don’t recommend using any other kind of flour because it will affect the cake texture.

Lemon: You will need lemon juice and zest from about two lemons.

Cake Texture

This cake has a unique texture. The outside has a brown crust/shell. It’s very delicate and will crack once you cut into the cake. The texture of the crust is like a thin sweet wafer cookie. Underneath the shell is an airy cake that has a texture like a sponge cake.

This cake is not overly sweet and has a nice lemon flavor and smell.

This cake is a lemon variation on my 3 Ingredient Cake.

Tips for Making Lemon Cake

Make sure you whip the eggs long enough. It’s the key to the cake rising properly. I beat mine for 10 minutes on the highest setting on my stand mixer. If you use a hand mixer, you may need to beat longer. The mixture will more than triple in volume, become very thick, and turn a very pale yellow. The mixture looks thick enough that it seems like it might be turning into meringue. As soon as you stop the mixer though, the mixture will immediately deflate and turn more liquidy and bubbly, like this.

You do not need any baking powder, baking soda or any other rising agent.

Be careful not to add too much lemon juice as it will affect your cake’s ability to rise properly.

This cake does need a few hours to cool, so I recommend making it the night before an event. Letting the cake cool will make it easier to cut and also will allow the crackly surface to firm up more.

4 Ingredient Lemon Cake

This unique lemon cake is perfect to serve for special events like holiday brunches, family gatherings and more. It is just 4 ingredients. The cake is light and airy and has a delicate sweet crackly crust.

Ingredients

  • 3 large eggs, straight from fridge
  • 1 cup (195 g) granulated white sugar
  • 1/4 cup (59 ml) lemon juice + 1 tbsp (5 g) lemon zest
  • 1 cup (128 g) all purpose flour

Instructions
 

  • Preheat oven to 350°F (177°C). Grease the interior of a 7.5 inch round springform pan (you can also use a 7 inch or 8 inch) and then line the bottom with parchment paper. Make sure the sides of the cake pan are thoroughly greased, otherwise the cake will stick to it.
  • In a large mixing bowl, add eggs and sugar. Beat on highest speed for about 10 minutes or until mixture becomes very thick and turns a very pale yellow, and more than triples in volume. Once you stop beating, the mixture will immediately deflate. This is normal. See notes section for more details.
  • Add in the lemon juice and zest. Beat mixture for a few seconds until fully incorporated.
  • Use a mesh strainer or flour sifter to sift in 1/3 of the flour into the egg mixture. You need to sift the flour in so that you can incorporate the flour into the egg mixture without deflating too much air from the egg mixture. Use a spatula to fold the flour into the egg mixture. Fold until flour is completely incorporated and you don't see any flour lumps. Repeat with another 1/3 of the flour and then the final 1/3.
  • Pour batter into prepared pan. Bake for about 30-35 minutes (mine was done at 33 minutes). If using a 7 inch pan you may need a little longer and if using an 8 inch pan you may need to reduce the time by a few minutes. The surface of the cake should be light brown. A toothpick inserted should come out clean (be careful when inserting the toothpick as you don't want to break the shell too much. It is very delicate and will crack easily).
  • Let cake cool completely before removing. It's best to let the cake cool for several hours as it will make it easier to cut and also will let the shell firm up more. If desired, dust cake with powdered sugar before serving. Cut cake slowly and gently with a sharp knife so that the top shell layer doesn't crack too much and the sponge layer doesn't get squished.

Notes

  • The cake needs a few hours to cool. I usually make mine the night before I plan on serving it.
  • You need to make sure your eggs are whipped to the right consistency. Your mixture should look like it is about to turn into a meringue and more than triple in volume. When you turn off the beaters, the mixture will sink back down quickly and will become more liquidy and bubbly again. See photo in the post for reference.
  • Make sure to gently fold the flour in so you don't deflate the egg mixture too much.
  • Be careful not to add too much lemon juice. I found that 1/4 cup was just the right amount without affecting the texture of the cake. You can use less but not more than 1/4 cup.
  • I used US standard large eggs.
  • You can make this in an 8 inch springform pan but your cake will not be as thick and you will need to reduce baking time.
