                Wash and dry the Fuji apples. Slice off the top quarter near the stem, then scoop out the core and some flesh with a spoon or melon baller, leaving a 1/3-inch border to form apple cups. Arrange in a baking dish and brush interiors with fresh lemon juice to prevent browning.

                In a bowl, whisk together pumpkin purée, heavy cream, brown sugar, maple syrup, pumpkin pie spice, vanilla extract, and egg until smooth and uniform. Ensure no lumps remain for even baking.

                Spoon the pumpkin pie filling into the hollowed apples, filling to just below the rim. Bake at 175°C (350°F) for 35–40 minutes until the custard sets with a slight jiggle and apples are tender when pierced with a fork.

                While apples bake, whip very cold heavy cream in a chilled bowl with an electric mixer at medium-high speed. When soft peaks form, add powdered sugar and vanilla extract, then continue whipping until stiff peaks develop. Keep refrigerated until serving.

                Allow baked apples to cool for at least 10 minutes. Top each with a generous dollop of whipped cream, sprinkle crushed graham crackers, and finish with a caramel sauce drizzle just before serving.
