01 - Heat vegetable oil in a large pot over medium heat. Add popcorn kernels and cover with a lid. Shake occasionally until popping slows, then remove from heat. Transfer 6 cups of popped popcorn to a large bowl, discarding unpopped kernels.
02 - Melt butter in a small saucepan over medium-low heat. Stir in brown sugar, molasses, ground ginger, cinnamon, nutmeg, cloves, and salt. Cook, stirring constantly, until the mixture bubbles, about 2 to 3 minutes. Remove from heat and stir in vanilla extract.
03 - Quickly pour the warm gingerbread coating over the popcorn. Toss thoroughly with a spatula or clean hands to coat evenly.
04 - Spread coated popcorn onto a parchment-lined baking sheet. Allow to cool for 10 minutes to set. Break apart any large clusters before serving.
