Ingredients

For the Crumb Layers ("Sand")

• Pastry scraps, baked puff pastry, or crushed cookies (such as graham crackers)
• Optional: a little melted butter and sugar if using plain crumbs

For the Custard Cream

• 4 egg yolks
• 1/2 cup (100g) sugar
• 2 cups (500ml) milk
• 2 tablespoons all-purpose flour
• 1 teaspoon vanilla extract (optional)

Instructions

1. Prepare the Crumb Layers ("Sand")

Crush the pastry, puff pastry, or cookies into fine crumbs.

Add the crumbs to a dry skillet over medium heat.

Stir constantly to toast them evenly until golden brown, about 8 to 10 minutes. Watch carefully to avoid burning.

Remove from the heat and allow them to cool completely.

For extra richness, you can mix the crumbs with a little melted butter and sugar before toasting.

The secret behind this dessert is the silky homemade custard. Once you master it, you'll want to use it in countless other desserts too.

2. Make the Custard Cream

In a non-stick saucepan, whisk together the sugar and egg yolks until pale and smooth.

Gradually pour in the milk while whisking continuously.

Add the flour and mix until completely smooth with no lumps.

Place the saucepan over medium heat and cook, stirring constantly.

Continue cooking for 6 to 10 minutes, or until the mixture thickens to a rich pudding-like consistency.

Remove from the heat and stir in the vanilla extract if using.

Allow the custard to cool to room temperature before assembling the dessert.

3. Assemble the Napoleon in a Glass

Place about 2 tablespoons of toasted crumbs in the bottom of each serving glass.

Add approximately 2 tablespoons of custard cream over the crumbs.

Repeat the layers until the glass is full, finishing with a layer of crumbs on top.

Depending on the size of your glasses, you can create three to four beautiful layers.

After layering comes the magic moment: chilling. This resting time allows the flavors to blend and the texture to become irresistibly creamy.

4. Chill and Serve

Refrigerate the dessert for at least one hour before serving. This helps the layers set and allows the flavors to develop fully.
