Preheat oven to 300 degrees F and line a baking sheet with parchment paper.
Combine Chex, almonds, cashews and pretzels in a large mixing bowl and mix together.
Melt coconut oil, then pour over the top of the mixture, followed by maple syrup, vanilla extract, coconut sugar, cinnamon and nutmeg. Gently mix together until all ingredients are well-covered.
Pour entire mixture over parchment paper and spread out evenly. Bake for 40 minutes, tossing every 15 minutes.
Once done, let cool for 15 minutes.
Transfer to a large bowl, then add in mini marshmallows & chocolate chips. Enjoy! :)
