The ultimate lemon cake recipe! My lemon mousse cake is so light and fluffy and packed with lemon flavor! It’s made with delicate lemon cake layers spread with lemon curd, a fluffy whipped cream and lemon curd mousse and topped with lemon jello! I’m using my ‘Simple Vanilla Cake‘ and ‘Easy Lemon Curd’ recipes for this stunning cake! I’ve made hundreds of cakes so it’s hard to impress me but this cake is amazing! An A++ in my books!

Lemon Cake Layers

For this incredible lemon mousse cake, I’m using a lemon flavored version of my ‘Simple Vanilla Cake’ recipe. I have a separate video recipe for this cake and I use it for many of my other cake recipes. To add lemon flavor, I replaced the vanilla extract with 2 teaspoons of lemon extract and the zest from 2 large lemons. Allow the cake layers to cool completely before using them for the mousse cake! Level the cooled cakes before assembling.

Lemon Mousse

The light and fluffy lemon mousse really makes this cake extra special! It’s just melts in your mouth and it’s so delicious! This lemon mousse recipe is made with whipped cream and my ‘Easy Lemon Curd’ recipe for the lemon flavor. I also add gelatin to help set the mousse. First, whisk the heavy cream and sugar until stiff peaks form, then add the chilled lemon curd. Make sure it’s completely cooled before adding! Next, add in the dissolved gelatin while it’s hot! Don’t wait for it to cool, otherwise it will form clumps in the mousse! This recipe will also work well with agar gelatin.

Assembling the Cake

I assemble this delicious lemon cake in a springform pan with the help of an acetate cake collar. I buy this plastic in a bulk roll on Amazon (affiliate link) and use it for all my no-bake desserts and mousse cakes. Before layering the cake, first spread a few tablespoons of lemon curd onto each layer, then layer into the prepare springform pan with 3 cups of mousse between each layer. Refrigerate the cake for at least an hour before adding the jello layer on top, then refrigerate overnight for best results!
