Yield: 4 servings
* 1/2 cup water
* 1/4 cup unsalted butter, cut into pieces
* 1 1/2 teaspoons plus 3 tablespoons sugar
* Pinch of salt
* 1/2 cup all purpose flour
* 3 large eggs
* 1 (8-ounce) container mascarpone cheese
* 3/4 cup ricotta cheese
* 1 teaspoon vanilla extract
* 1/2 cup chocolate-hazelnut spread (such as Nutella)
* 1/4 cup whipping cream
* 1/4 cup hazelnuts, toasted, husked, chopped
Preheat the oven to 375 degrees F.
Line a heavy large baking sheet with a silpat or parchment paper.
Combine the water, butter, 1 1/2 teaspoons of sugar, and salt in a
heavy medium saucepan. Bring to a boil, stirring until the butter
melts. Add the flour and stir over medium heat for 1 minute. Cool 5
Crack 2 eggs into a measuring cup. Use a wooden spoon to beat the eggs
into the dough, 1 at a time. Spoon 10 or 12 (1 1/2-inch) mounds of
dough onto the prepared baking sheet, spacing 2 inches apart. Beat the
remaining egg in a small bowl to blend. Gently brush the egg over the
dough mounds (do not drip the egg onto the baking sheet).
Bake the pastries until they are amber brown, about 50 minutes. Allow
the pastries to cool completely.
Mix the mascarpone, ricotta, vanilla, and remaining 3 tablespoons of
sugar in a medium bowl. Refrigerate until cold. Using a serrated
knife, cut the tops off the pastry and set aside. Spoon the mascarpone
mixture into the pastries and top with its lid.
Combine the chocolate-hazelnut spread and cream in a small bowl. Heat
in the microwave for about 30 seconds until warm. Stir the mixture.
Spoon the chocolate-hazelnut sauce atop the pastries. Sprinkle with
the hazelnuts and serve.
