Preheat oven at 350F and prepare a baking sheet with parchment paper.
In a mixing bowl, combine your mixed nuts, maple syrup, brown sugar, vanilla extract, nutmeg, cinnamon, and all spice. Mix everything together until well combined.
Pour the nut mixture on a baking tray and make sure that the nuts are in a single layer.
Bake for about 15-20 minutes or until it is at your desired roast! Flip halfway for even sugary crunch.
Once done, take out of the oven and let cool for 20-30 minutes.
