Preheat the convection oven to 350 degrees F. Line a cupcake or muffin pan with regular-size cupcake liners.
In a mixing bowl of a stand mixer fitted with a paddle attachment, mix the sugar and eggs until pale yellow. Add the melted butter, orange juice and vanilla. Then add the pumpkin puree. Add the cinnamon, nutmeg and ginger to the mixing bowl, and combine thoroughly.
In a separate bowl, combine the flour, baking powder, baking soda and salt. Add the dry ingredients and the sour cream to the egg mixture, alternating between the dry ingredients and the sour cream. Fill the prepared cupcake liners three-quarters of the way full with the batter. Bake until a toothpick inserted in the center comes out clean, 14 to 16 minutes.
To assemble: Top the pumpkin cupcake with a dollop on top of the Vanilla Chantilly. Roll the sides of the cupcake in the Crumble to coat.
In a mixing bowl fitted with a whisk attachment, whip 3 cups of the heavy cream until it starts to get thick. Add the powdered sugar a little at a time while it is whipping, being careful not to over mix the cream. Then add the vanilla. At this point the whipped cream should be at a soft peak. Bloom the gelatin with the remaining 6 tablespoons heavy cream When the gelatin is completely bloomed, put in the microwave at 10 second increments until melted. Then add the warm liquid to the whipped cream. Put the vanilla chantilly in a piping bag fitted with a round tip.
Preheat the oven to 350 degrees F. In the bowl of a standing mixer fitted with a paddle, combine the flour, sugar, butter, baking powder, cinnamon and salt. Mix just enough to combine. Spread the crumble on a sheet tray in a thin layer and bake until golden brown. (The crumble can also be used as topping for muffins and quick breads.)
