Preheat oven to 325°F (163°C) and line a baking sheet with parchment paper.
In a large bowl, combine sourdough discard, oats, flaxseed, chia seeds, pumpkin seeds (or pecans), maple syrup, vanilla, oil, and cinnamon. Stir until fully coated.
Spread mixture onto the baking sheet in a thin, even layer. Press down firmly for clusters.
Bake for 25–30 minutes, until lightly golden. Do not stir.
Let granola cool completely on the pan—it will crisp up as it cools.
Stir in white chocolate chips, then break into clusters and enjoy!
