Creating a Galette de Rois can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Almond Cream: In a mixing bowl, combine almond flour, sugar, softened butter, one egg, vanilla extract, and rum (if using). Mix until smooth and creamy.
3. Prepare Pastry: Roll out the puff pastry sheets on a lightly floured surface. Cut them into two circles, approximately 10 inches in diameter.
4. Assemble the Galette: Place one pastry circle on a baking sheet lined with parchment paper. Spread the almond cream evenly on top, leaving about 1 inch of space at the edges.
5. Insert the Fève: Gently press the fève into the almond cream, ensuring it’s buried within the filling.
6. Cover with Pastry: Place the second pastry circle on top and press the edges together to seal. Use a fork to crimp the edges for a decorative touch.
7. Prepare Egg Wash: Beat the remaining egg and brush it over the top of the pastry for a golden finish.
8. Decorate: Use a knife to lightly score the top in a decorative pattern, being careful not to cut through the pastry.
9. Bake: Place the galette in the preheated oven and bake for 30-40 minutes or until golden brown and puffed.
10. Cool: Remove from the oven and let it cool on a wire rack for about 20 minutes before serving.
