In a large bowl, combine the sourdough discard, melted coconut oil, maple syrup, vanilla extract, cinnamon, and sea salt. Stir until smooth and well mixed.

Add in the rolled oats, pumpkin seeds, chopped walnuts, or any other toppings you’re baking into the granola. Mix again until everything is evenly coated.

Spread the mixture into a thin, even layer on a parchment-lined baking sheet.

Let cool completely before breaking into clusters. Add any extra mix-ins at this point, like dried fruit or chocolate chips that you didn’t bake into the granola.
