Preheat oven to 170 degrees C.
Line a small baking tray with parchment or baking paper.
Place cooked popcorn and pumpkin seeds in a large bowl and set aside.
In a saucepan, bring the maple syrup to a boil for 2 minutes watching to ensure it doesn't boil over.
Turn the heat down and stir in the almond butter, vanilla, sea salt and spices until completely combined.
Working quickly, pour the mixture over the cooked popcorn and stir to coat.
Turn the popcorn out on to the baking tray and press down with slightly wet hands.
To compress, press down again with the back of a spoon.
Pop in the oven and bake for 6 minutes, turn the pan and cook for another 2 minutes.
Remove from the oven and allow to cool before breaking in to nuggets.
