Prep: 1 hr 25 min | Cook: 30 min | Total: 2 hrs 10 min

Cost: $9.80 total, $1.22 per serving

Ingredients

  • 2 rolls Puff pastry (Thawed if frozen, each roll about 250 g)
  • 100 g Unsalted butter (At room temperature, very soft)
  • 80 g Granulated sugar (Finely ground)
  • 2 units Eggs (Large, at room temperature)
  • 80 g Grated coconut (Unsweetened, fresh or in a bag)
  • 100 g Dark chocolate chips (Minimum 70% cocoa; replace with milk chocolate for a "buouny" effect)
  • 2 units Egg yolk (for glazing) (Beaten with a tablespoon of water or milk)
  • 2 tbsp Water (To moisten the edges before sealing)
  • 1 unit Bean (Optional, to place in the filling)

Instructions

  1. Prepare the filling

    In a bowl, cream the soft butter with the sugar until a pale mixture forms. Add the eggs one at a time, mixing well after each addition. Fold in the grated coconut then the chocolate chips. Set aside.

    Time: PT10M

  2. Spread the filling on the first disc

    Transfer the mixture into a pastry bag (or use a spoon) and spread it evenly over the first puff pastry disc, leaving a free edge of about 2 cm.

    Time: PT5M

  3. Moisten the edges and assemble the two discs

    Lightly brush the free edges of the first disc with water. Place the second puff pastry disc on top, then press firmly on the edges to seal.

    Time: PT5M

  4. Trim the excess pastry

    With a sharp knife, cut away the excess pastry around the edge. Keep the trimmings to make small palmiers or decorations.

    Time: PT5M

  5. First glaze

    Brush the surface of the galette with half of the beaten egg yolk (diluted with a little water).

    Time: PT2M

  6. Chill in the refrigerator

    Place the galette on a baking sheet lined with parchment paper and refrigerate for at least 1 hour (ideally overnight) so the pastry relaxes and the layers stay well separated.

    Time: PT1H

    Temperature: 4°C

  7. Second glaze and decoration

    Remove the galette from the refrigerator, brush it with the second egg yolk. Decorate as you like (patterns, leaves, etc.) then cut four small openings 1 cm deep to let steam escape.

    Time: PT5M

  8. Baking

    Bake the galette in the preheated oven at 200°C for 30 minutes, until it is nicely golden and the puff pastry has risen well.

    Time: PT30M

    Temperature: 200°C

  9. Rest and serving

    Let the galette rest for 10 minutes out of the oven before cutting. Insert the bean into the filling before serving.

    Time: PT10M

Critical Steps — Do Not Skip

  • Moisten the edges and assemble the two discs
  • Chill in the refrigerator
  • Second glaze and ventilation cuts
  • Baking at 200°C for 30 minutes

Chef Tips from the Video

  • Use high-quality butter for a more flavorful puff pastry.
  • Cooling the filling before spreading it on the pastry prevents the pastry from becoming soggy.
  • For an even shinier glaze, add a teaspoon of milk to the egg yolk.

Troubleshooting

Filling overflows during baking

Reduce the amount of filling or leave a wider edge (3 cm) before sealing the two discs.

The pastry does not rise, stays flat

Ensure the chill in the refrigerator lasted at least 1 hour and that the oven was properly preheated to 200°C.

The edges are too brown or burnt

Cover the galette with a sheet of aluminum foil halfway through cooking or reduce the temperature to 190°C.

Storage

Refrigerator: Store in an airtight container for up to 2 days.

Freezer: Not recommended; puff pastry loses its flakiness.

Room temperature: Consume the same day, otherwise keep refrigerated.

Make-Ahead Tips

  • Prepare the filling the day before and keep it refrigerated.
  • Assemble the galette and refrigerate overnight; bake it on the same day.
