When the cake is completely cool, remove the parchment paper and cut 3 circles out of the dough. We reserve until the moment of assembly. If necessary, we equalize the height of each circle to make it easier for us when assembling the cake. With the leftover cake, we can make cake pops or save it for breakfast.

To make the cream or buttercream, put in a bowl 150 grams of unsalted butter at room temperature, 150 grams of icing sugar and the zest and juice of 1 lemon. We beat first at low speed until the ingredients are integrated and then at medium-high speed until the mixture clears up and is very creamy. It can take between 10 and 20 minutes to get the desired texture.

We start assembling the cake by putting a little cream in the center of the parchment paper and placing one of the biscuits on top. We put a portion of cream on top. We repeat with the next cake and with another portion of cream.
