Petits fours with chocolate mousse and meringue are elegant, bite-sized pastries that trace their roots back to the 18th-century French culinary tradition. The name 'petit four' literally translates to 'in a small oven,' harkening back to a time when bakers utilized the residual heat of brick ovens to bake these tiny treats. In our recipe, a crumbly, buttery shortcrust pastry meets a luscious, velvety chocolate mousse, all crowned with a crisp meringue and a vibrant dried cherry. These delicate sweets not only offer a rich, complex flavor profile but also bring stunning visual appeal, creating the ambiance of an authentic Parisian café right in your home.

How to Make Petits Fours with Chocolate Mousse and Meringue
First, let’s make the meringue for garnishing our petits fours. Crack the egg and separate the egg white. We won’t need the yolk for this step, but you can save it for the dough. Beat the egg white with a mixer for a few minutes, gradually increasing the speed to maximum. Once the egg white becomes fluffy, add the sugar in small batches, continuing to whip for about 10 minutes. A minute before finishing, add a pinch of citric acid or a splash of lemon juice. Transfer the glossy meringue into a piping bag or a parchment cornet. Line a baking sheet with parchment paper, pipe out small, bite-sized meringues, and immediately pop them into an oven preheated to 100°C (210°F).
Pipe out small portions of meringue onto a baking sheet, leaving a little distance between them for even baking.
Bake the meringues for 45 minutes, then turn off the oven, crack the door slightly open, and leave them for 10 minutes. Remove them from the parchment right away. Once fully cooled, you can store them in a glass jar for a few days.
The finished meringue should be dry and light. Let it cool in a slightly open oven so it doesn't crack from temperature drops.
Now, let’s make the dough. Beat the softened butter with sugar for 5 minutes. Crack in the egg, pour in the cold water, add a pinch of fine salt, and mix until combined.
Whip the butter until fluffy, then add the rest of the liquid ingredients, creating the base for the shortcrust pastry.
Sift in the all-purpose flour and gently knead the dough.
Gradually fold in the sifted flour so the dough turns out tender and crumbly after baking.
Chill the dough in the refrigerator for half an hour. Dust your work surface with flour and roll the dough out thinly.
Roll out the dough into a thin layer on a floured surface so the petit four bases are delicate.
Cut out circles using a thin-rimmed glass or a cookie cutter. Press them into metal tartlet molds, trimming the edges for a neat finish. Chill the molds with the dough in the refrigerator for 15 minutes, and meanwhile, preheat your oven to 180°C (350°F).
Carefully line the bottom and sides of the molds with the dough, pressing it tightly to the edges for a beautiful relief.
Bake the shortcrust pastry bases in the preheated oven for about 12 minutes until beautifully golden. Let them cool completely on a wire rack.
The shortcrust pastry baskets are ready when they acquire an appetizing golden hue. Let them cool completely.
Drop a teaspoon of thick strawberry jam into the bottom of each petit four.
A small amount of thick berry jam at the bottom will add an interesting flavor note to the dessert.
Next, the chocolate mousse. Whip the mascarpone with powdered sugar for 5 minutes.
Whip the mascarpone to a creamy state so the mousse turns out smooth and stable.
In a separate bowl, whip the heavy cream (at least 33% fat). Gently fold the whipped cream into the mascarpone.
Gently, using circular motions, fold the two masses together, trying to keep as much airiness as possible.
Melt the dark chocolate over a double boiler or in the microwave. Carefully fold the melted chocolate into the cream and mascarpone mixture until perfectly smooth.
After adding the chocolate, the mousse becomes rich and thick. Now it is ready to fill the dessert.
Transfer the mousse into a piping bag fitted with a star nozzle and generously fill the petits fours.
Use a piping bag with a star nozzle to create beautiful peaks of chocolate mousse.
Toast the cashews in the oven until golden. Right before serving, garnish your petits fours with the meringues, toasted cashews, dried cherries, and a sprinkle of colorful sweet confetti.
Finish by garnishing each petit four with a crunchy meringue, cashews, and a dried cherry.
Petits fours with chocolate mousse and meringue are best served chilled, ensuring the mousse maintains its perfect, airy texture. They pair beautifully with a cup of robust espresso or a fragrant berry tea. If you feel like experimenting, try swapping the strawberry jam for orange marmalade - the slight citrus bitterness beautifully balances the sweetness of the dark chocolate. Store the assembled pastries in an airtight container in the refrigerator for no more than two days to keep the pastry base perfectly crisp. If you are prepping ahead, it's best to bake the tartlet shells and meringues a day in advance, filling them with the mousse just before serving. This guarantees the ultimate textural contrast between the silky cream and the crunchy garnishes, earning you rave reviews from your guests.
