Preheat oven to about 195°F (90°C). Line a large baking sheet with parchment.
Mix dry base: In a large bowl, combine walnuts, almonds, pumpkin seeds, flaxseeds, chia seeds, sesame seeds, and cinnamon.
Binder (microwave option): In a microwave-safe bowl, combine date syrup and tahini. Heat on medium power for 20–30 seconds until just loosened. Stir smooth, then mix in vanilla.Saucepan option: Combine date syrup and tahini in a small saucepan. Heat over low heat for about 1 minute, or until just loosened. Stir smooth, then mix in vanilla.
Combine: Pour binder over dry mix. Stir until evenly coated and small clumps form.
Bake: Spread the mixture in a thin, even layer on the baking tray. Bake for about 60 minutes, or until mostly dry to the touch.
Cool: Remove the sheet of granola from the warm parchment paper and set aside to cool. Let it cool completely before breaking it into small clusters.
For serving: Enjoy like cereal with non-dairy milk, layer it with yogurt, or pair it with oatmeal or another moist food.
Notes
Using low heat can help preserve more micronutrients.
One serving provides 43–48% of the Daily Value for magnesium.
Add cocoa powder as desired, but heating cocoa reduces its flavanol content.
One serving is about one-third cup.
For a nut-free option, substitute the nuts with the same amount of sunflower seeds, hemp seeds, or seeds of your choice.
If you prefer sweeter granola, use an extra tablespoon of date syrup. This version is lightly sweetened.
