In a saucepan, heat coconut oil and honey until warm. Stir in cocoa powder.

In a large bowl, combine oats and nuts. Stir in honey mixture until evenly coated.

Spread mixture in an even layer on a rimmed baking sheet. Bake for 15 minutes, stirring every 5 minutes. Remove from oven.

To make "clusters", immediately press down firmly on the mixture with a wet paper towel. Let cool. Break into smaller pieces.
