Pre-heat Oven: Pre-heat oven to 325 degrees F. Line a baking dish with parchment paper and set aside.
Prep Bars: Give all of the nuts a gentle chop. Add them all to a medium-sized bowl with chia seeds and puffed rice cereal and give a quick mix. Add maple syrup and honey and give a good mix, ensuring that it is all well coated.
Bake: Add the nut mixture to the parchment paper-lined baking dish. Use a spatula or the back of a measuring cup to flatten the nut mixture into an even layer. Bake for 35 minutes.
Cool: Remove the baking dish from the oven and let rest in the dish for 5 minutes. Then remove from the baking dish and let cool for at least 45-50 minutes at room temperature or for 20-30 minutes in the fridge.
Melt Chocolate: Add chocolate chips and coconut oil to either a double boiler or a small microwaveable safe dish and melt. If melting in the microwave, microwave for 15 seconds and then mix, and microwave for another 15 seconds and mix until it is completely melted.
Spread Chocolate: Once completely cooled, remove the baked nut mixture from the fridge (or freezer) and gently turn it over. Spread the melted chocolate in an even layer. Return to fridge for 10-20 minutes (or the freezer) to let the chocolate set.
Cut Bars: Once the chocolate has set, use a very sharp knife to gently cut it into bars. Store in a cool dry place, or in the fridge.
