Preheat oven: Preheat your oven to 160°C (320°F).
Mix wet ingredients: In a large bowl, whisk together the 35 milliliters olive oil and 200 milliliters maple syrup.
Combine everything: Add the 500 grams oats, 200 grams pecans, 200 grams almonds, chopped, 110 grams pumpkin seeds, 100 grams sunflower seeds, 75 grams coconut flakes, 2 teaspoons cinnamon, and 1 teaspoons cardamom. Stir until everything is evenly coated.
Spread on a baking tray: Spread the mixture evenly across a large, parchment-lined baking tray.
Bake: Bake for 15 minutes, stirring every 5 minutes so it toasts evenly and doesn't burn around the edges.
Cool completely: Remove from the oven and let it cool completely on the tray - this is what gives it that signature crunch. It will continue to crisp up as it cools.
