Ingredients
For the dough:
- 9 whole graham crackers (1 sleeve)
- 1 1/4 cups all-purpose flour
- 1 teaspoon fine salt
- 2 sticks (8 ounces) cold unsalted butter, cut into 1/2-inch cubes
- 2 large egg yolks
- 1/4 cup whole milk
To assemble:
- Flour, for rolling the dough
- 1 large egg
- 1 teaspoon water
- About 1 cup marshmallow fluff
For the topping:
- 6 ounces milk chocolate, finely chopped
Directions
For the dough:
-
Place the graham crackers in a resealable plastic bag, press out the air, and seal, leaving about 1 inch unsealed. Using a rolling pin, roll over the crackers until they are fine, uniform crumbs (you should have about 1 1/4 cups).
-
Whisk the flour, graham cracker crumbs, and salt in a large bowl until combined. Add the butter and toss with your fingers until well coated in the flour mixture. Using a pastry blender or your fingers, cut the butter into the dry ingredients until the butter pieces are the size of peas.
-
Whisk the egg yolks and milk in a measuring cup or small bowl until combined. Add the egg-milk mixture to the flour mixture and mix with your hands until a dough forms (it will be a little sticky). Divide the dough into 2 equal portions and shape into 2 (6-by-5-inch) rectangles. Wrap each tightly in plastic wrap and refrigerate for at least 1 1/2 hours.
To assemble the tarts:
-
Heat the oven to 375°F. Line a baking sheet with parchment paper; set aside.
-
Lightly dust a work surface with flour and roll 1 dough portion out into a rough 12-by-10-inch rectangle, rotating the dough and reflouring the surface and rolling pin often to prevent the dough from sticking. Using a pizza cutter or sharp knife, trim the dough to a 10-1/2-by-9-inch rectangle. Cut that into 6 equal rectangles (each about 3 1/2 inches wide by 4 1/2 inches tall). Using a flat spatula, transfer the rectangles to the prepared baking sheet, leaving about 2 inches of space between each. Place the baking sheet in the refrigerator.
-
Whisk the egg and water in a small bowl until evenly combined; set aside. Roll out the second dough portion to the same dimensions as the first, trim, and cut into 6 rectangles.
-
Remove the baking sheet from the refrigerator and brush a thin coating of the egg wash over 3 of the dough rectangles. Spread 2 rounded tablespoons of marshmallow fluff onto each of these rectangles, leaving a 3/4-inch border. Place 3 nonchilled rectangles over the marshmallow fluff, press on the edges to adhere, and push down gently on the filling to slightly flatten. Using a fork dipped in flour, crimp the edges of the tarts. Repeat with the remaining dough rectangles and fluff. Cut two 2-inch slits to form an “X” in the center of each tart. Place in the refrigerator until the dough has stiffened slightly, about 15 to 20 minutes.
-
When the dough is ready, bake until golden brown and the marshmallow fluff has puffed, about 20 to 23 minutes (the marshmallow fluff will deflate as it cools). Transfer to a wire rack and let cool completely.
For the topping:
-
While the tarts are cooling, place the milk chocolate in a small microwave-safe bowl. Melt the chocolate in 15-second bursts in the microwave, stirring after each burst, until smooth.
-
Set the wire rack with the tarts on it over a baking sheet. Place melted chocolate in a zip-top bag, cut a small opening on one corner of the bag, and drizzle chocolate over tarts. Eat right away, or let the chocolate set before serving.
