Ingredients
Unbleached all-purpose flour, for dusting
1 sheet (about 14 ounces) all-butter puff pastry, such as Dufour, thawed completely in refrigerator
1/4 cup chocolate-hazelnut spread, such as Nutella
Strawberries, halved if large, and warmed pure maple syrup, for serving
Preparation
Preheat a nonstick waffle iron according to manufacturer’s instructions. Dust a clean work surface with flour and roll out pastry to flatten creases; cut in half crosswise.
Dollop chocolate-hazelnut spread by the teaspoon onto one piece of dough, spaced 2 inches from edges of dough and 2 inches apart. Brush between dollops with water, then top with second piece of dough, pressing gently between dollops to seal.
Center a 2 1/2-inch heart-shaped cookie cutter over dollops and stamp out shapes. Freeze 5 minutes. Cook in waffle iron until puffed and golden, 5 to 6 minutes. Serve with strawberries and syrup.
