# What you'll need:
→ Croissants
01 - 4 large all-butter croissants (preferably day-old)
→ Pistachio cream
02 - 3.5 oz (about 3/4 cup) unsalted shelled pistachios
03 - 5 tablespoons granulated sugar
04 - 5 2/3 tablespoons unsalted butter, softened
05 - 1 large egg
06 - 1 tablespoon heavy cream
07 - 1/2 teaspoon pure vanilla extract
08 - Pinch of fine salt
→ Topping & decoration
09 - 2 tablespoons chopped pistachios
10 - 2 tablespoons powdered sugar for dusting
# Directions:
01 - Preheat the oven to 350°F and line a baking sheet with parchment paper.
02 - In a food processor pulse the shelled pistachios with the granulated sugar until finely ground and uniform in texture.
03 - Add the softened butter, egg, heavy cream, vanilla and a pinch of salt to the processor; blend until the mixture is smooth, glossy and spreadable.
04 - Using a sharp knife, slice each croissant horizontally, leaving a hinge so each opens like a book.
05 - Generously spread the pistachio cream into the cavity of each croissant and close them, reserving a little filling for the tops.
06 - Arrange the filled croissants on the prepared sheet, pipe or spread remaining cream over the tops, then bake for 15–20 minutes until the pastry is crisp and the filling is lightly golden.
07 - Let croissants cool briefly on a rack; finish with chopped pistachios and a light dusting of powdered sugar. Serve slightly warm.
