Pre-heat oven to 325 degrees F and line a sheet pan with parchment paper.
Mix the peanut butter, maple syrup and melted coconut oil in a large mixing bowl until smooth and creamy.
1/2 cup natural peanut butter, 1/4 cup pure maple syrup, 3 tbsp melted coconut oil
Stir in the oats and salt and mix well until fully coated and combined.
4 cups rolled oats, 1 tsp sea salt
Add the granola to the prepared pan and spread it into one even layer pressing it firmly into the pan. If you do not have a large enough pan for one layer, use two sheet pans. For best results and crunchy, clumpy granola, it's important it's pressed in one layer and not piled up.
Bake for 25-30 minutes. Check at 20 minutes then keep an eye on it every few minutes after that to prevent burning. It should be golden brown and fragrant when done.
Remove from oven and let cool completely on the pan before handling or storing. This is important as it will crisp up as it cools. Once it's cool, mix in any desired add-ins then store in an airtight container at room temperature.
