In a bowl with a whisk, whip the cream with the vanilla until mousse-like (it won't form peaks.) Sift the remaining ingredients together and stir them into the cream to make a batter. Let the batter sit for 30 minutes.
Heat up waffle cone iron and brush with a little oil. Pour some batter in and close the lid to bake and brown. Open the iron and remove the browned batter and fold over itself, overlapping it, on a wooden cone-form into a cone. Let cool then top with a scoop of ice cream.
