Ingredients:
- 1 sheet puff pastry (approx. 10 oz), thawed but chilled
- 1 large egg
- 1 tablespoon water
- 3 tablespoons coarse sanding sugar
- 1.5 cups heavy whipping cream, cold
- 0.5 cup powdered sugar, sifted
- 1 teaspoon vanilla extract
- 2 tablespoons marshmallow fluff or softened cream cheese
Instructions:
- On a lightly floured surface, roll the puff pastry sheet slightly to even it out. Using a pizza cutter or pastry wheel, cut the dough into 12 even strips approximately 1-inch wide.
- Starting at the pointed end of a stainless steel cream horn mold, wind one pastry strip around the cone, overlapping the edges by about 1/4 inch. Stop 1/2 inch from the wide end.
- Place wrapped molds on a parchment-lined baking sheet and chill in the refrigerator for 10 minutes.
- Whisk the egg and 1 tablespoon of water to create an egg wash. Brush the tops of the horns with egg wash and roll in sanding sugar, keeping the seam side down.
- Bake at 400°F (200°C) for 15–18 minutes until the pastry is deeply golden brown and puffed.
- Cool for 5 minutes. While still warm, gently twist the metal mold and slide it out. Transfer shells to a wire rack to cool completely.
- In a chilled bowl, beat heavy cream, powdered sugar, and vanilla until soft peaks form. Add marshmallow fluff (or cream cheese) and beat until stiff peaks form.
- Transfer filling to a piping bag and pipe into the completely cooled pastry shells from the bottom to the tip.
