Joconde base

It is a sheet of a kind of almond-flour sponge cake that will serve as the base for many filled cakes. Cut to the inside dimensions of the mould we will use, it allows us to make a layered cake.

Step-by-step Guide

Preparation

  1. Preheat the oven to 180 ºC.
  2. Whisk the whole eggs at room temperature with the icing sugar and almond flour, using electric beaters, until you obtain a foamy mixture that doubles in volume. Set aside.
  3. In another large bowl, whip the egg whites with a pinch of salt until they reach stiff peaks, so that the peaks hold their shape.
  4. Sift the wheat flour over the whole egg and almond flour mixture, and gently fold it in with a rubber spatula.
  5. Fold in the whipped egg whites in three batches, stirring gently.
  6. Finally, add the melted butter and stir gently.

Baking and finishing

  1. Line a flat baking tray with low sides with parchment paper and pour in the batter.
  2. Spread the batter with a long metal spatula so that it is even, with the same thickness over the entire surface of the tray, for even baking.
  3. Bake at 180 ºC for 10-12 minutes.
  4. Remove the tray from the oven.
  5. Carefully remove the sheet of cake from the tray and place it on the counter.
  6. Cover it with a new sheet of parchment paper, turn it over and, gently, peel off the browned baking paper.
  7. Leave the sheet to cool.

Layer assembly

  1. Once cool, place the mould you will use to assemble the cake on top of the sheet and cut one layer following the inside of the mould.
  2. Move the mould just to the edge of the previous cut and cut a second sheet layer.
  3. These two whole sheet layers will serve as the base and the third layer of the cake.
  4. Try to use the best remaining pieces and make several cuts that allow you to build a second layer; even if it is made of pieces, it will not be noticeable because it will have filling underneath and on top.
