Step 1

To make the almond cream filling, combine all the ingredients (almond meal, sugar, egg, vanilla extract, softened butter, and flour) in a food processor. Blend until a smooth and creamy paste is formed.

Step 2

Preheat the oven to 325 degrees Fahrenheit and line a baking sheet with parchment paper.

Step 3

Roll out the puff pastry sheets and cut out two 11-inch circles.

Step 4

Place the first circle on the prepared baking sheet and spread an even layer of the almond cream. Be sure to leave a 1-inch border around the edges.

Step 5

If using fava bean, add it at this point. Nestle it in the almond cream.

Step 6

Place the second disc on top of the filling and crimp the edges to seal the cake.

Step 7

Use a sharp knife to score a decorative pattern into the top layer of the pastry. Make sure though not to cut through the almond filling.

Step 8

Brush the galette with the beaten egg.

Step 9

Bake for about 15 minutes.

Step 10

Step 11

Cool the cake for about 20 minutes.
