Dry Ingredients: In a large bowl, add the rolled oats, brown sugar, chopped pecans, ground flaxseed, cinnamon, and sea salt. Stir until evenly combined.
Wet Ingredients: In a separate bowl, stir the melted butter, maple syrup, and vanilla extract. Pour the mixture over the dry ingredients and stir until all the oats are well coated.
Line a large baking sheet with parchment paper and spread the granola into an even, single layer.
Bake at 250 degrees F for 75 minutes, or until lightly golden. Do not stir. Remove from the oven and allow the granola to cool completely without touching it. This helps clusters set.
Glaze Ingredients: In a small bowl, whisk together the powdered sugar, vanilla extract, and milk until smooth. Drizzle the glaze over the cooled granola using a fork. Let the glaze set before breaking the granola into clusters.
Store in an airtight container at room temperature for up to 7 days, or freeze for up to 3 months. Thaw at room temperature before serving.
Serve over yogurt or enjoy the clusters on their own as a snack.
