Preheat oven to 350°F. Grease a 9 x 13 baking dish.
Add rolled oats and water to a large mixing bowl. Stir until well combined and set aside for 5 minutes.
Add coconut, almonds, pecans and chocolate chips. Mix and set aside.
In a medium saucepan over low heat, melt honey, nut butter and coconut oil. Add almond milk, cocoa powder and maple syrup and mix until completely dissolved. Remove from heat and stir in vanilla.
Pour over oat mixture and mix thoroughly.
Press into baking dish using a spatula or slightly wet hands.
Bake for 15 minutes. Remove from oven and let cool slightly. Cut into 18 even-sized bars using a sharp knife.
Transfer to a parchment lined baking sheet and return to oven for another 10-12 minutes (until the edges are dry to the touch and golden brown).
Allow to cool for a few minutes, then transfer to a cooling rack. Store in an airtight container for up to a week or pop into the freezer.
