In a large mixing bowl, combine the rolled oats and vanilla protein powder. Mix well to ensure even distribution of the protein powder.
In a separate bowl, add the nut butter and maple syrup. Mix until the ingredients are well combined and form a smooth mixture.
Pour the nut butter and maple syrup mixture into the bowl with the oats and protein powder. Use a spatula or your hands to mix everything together until all the dry ingredients are evenly coated with the wet mixture.
Once the ingredients are well combined, preheat your oven to 180 degrees Celsius (350 degrees Fahrenheit).
Line a baking tray with parchment paper and spread the granola mixture evenly on the tray. Make sure the layer is not too thick to allow for even baking.
Place the tray in the preheated oven and bake the granola for 20 to 25 minutes, or until it turns golden brown. Remember to stir the granola every 10 minutes to ensure even cooking and prevent it from burning.
Once the granola is baked to perfection, remove it from the oven and let it cool completely on the tray. This will allow the granola to crisp up and develop its signature texture.
Once cooled, you can break the granola into smaller clusters or leave it as-is for a crunchier texture. At this point, you can also add your favorite mix-ins like dried fruit, chocolate chips, or coconut flakes to enhance the flavor and add extra texture to your granola.
