Preheat your oven to 180 degrees Celsius or 350 degrees Fahrenheit.
Spread the pecans or your chosen nuts on a baking sheet and toast them in the preheated oven for about 3-4 minutes until fragrant. Remove from the oven and set aside. Be careful not to burn them.
In a small bowl, mix the nut butter and maple syrup until well combined and smooth. If the nut butter is too thick, you can heat it in the microwave in 20-second bursts to soften it. Alternatively, you can add a small amount of tasteless oil, such as canola oil or refined coconut oil, to achieve a runny consistency.
In a large bowl, combine the rolled oats, ground cinnamon, and fine salt. Mix well to ensure the dry ingredients are evenly distributed.
Pour the wet ingredients into the bowl with the dry ingredients. Use a spatula or your hands to mix thoroughly, ensuring all the dry ingredients are coated with the wet mixture.
Line a baking tray with parchment paper and spread the granola mixture evenly on the tray.
Bake the granola in the preheated oven for 20 to 25 minutes, or until golden brown and fragrant. Take care to mix the granola every 5 to 10 minutes to ensure even cooking and prevent burning.
Once the granola is done, remove it from the oven and let it cool completely on the baking tray. Avoid stirring the granola while it cools, as this will allow it to form clusters and achieve a crunchy texture.
Once cooled, transfer the granola to an airtight jar or container for storage. It can be kept at room temperature for up to two weeks.
