Heat 4 cups oil (375° F) in a large Dutch oven.
Put flour, 1/3 cup sugar, baking powder, salt and spice in a large bowl and whisk lightly to mix.
Add cream, purée, vanilla, beaten egg and 2 tbsp oil, and stir until just combined. Don’t over mix.
Using a soup spoon, about 1 tbsp, carefully drop batter into the hot oil. Don’t over-crowd the pan —5-6 at a time should be enough. Fry for 2-3 minutes and flip, cooking for another couple of minutes or until fritters are deep golden brown.
Place the finished fritters on a plate covered with paper towels in a warm oven and continue frying the rest.
Mix the cinnamon with the remaining 1/3 cup sugar in a paper bag. Add the warm fritters and shake to cover.
Serve while still warm with a drizzle of maple syrup.
