1) Lightly butter a 22 by 22-cm baking dish.
2) In a large bowl, mix together the apples, sugars, flour, cinnamon, vanilla, salt, nutmeg and lemon. Add the mixture to the prepared baking dish.
3) Add all the topping ingredients to a medium bowl and combine well with a wooden spoon, to form a batter. Dollop the batter in various spots on top of the apple mixture. The batter will spread as it bakes. Put the cobbler in the oven and bake until the apples are tender and the crust is golden, about 30 minutes. Remove from the oven and serve with ginger whipped cream.
For the ginger whipped cream:
Add the cream and sugar to a medium bowl. Using a hand-held electric mixer and beat the cream until stiff peaks form, about 2 to 3 minutes. Fold in the ginger. Cover and chill up to 4 hours before serving.
