Preheat oven to 275 degrees. Top a rimmed baking sheet with parchment paper and set aside.
In a medium bowl, mix together brown sugar, honey, and vanilla.
In a large bowl, mix together oats, almonds, dried raspberries, chia seeds, and ground flax seed. Set aside.
In a small saucepan, melt the butter over low-medium heat. Stir continuously and allow the butter to come to a foamy boil. Continue stirring for about 5-6 minutes, until the butter deepens in color to a darker gold.
Remove from heat and slowly pour over the brown sugar, honey, vanilla mixture. Mix well.
Slowly pour combined brown butter mixture over the dry oats mixture. Toss ingredients together until everything is well blended.
Spread granola mix over the prepared baking sheet with parchment paper. Bake for 40-50 minutes until the granola has turned into a beautiful golden brown color.
Allow granola to cool on the baking sheet for about 5-10 minutes, then break into clusters and enjoy!
