Preheat your oven to 180°C / 350°F and line a baking tray with parchment paper.
Add the dates, olive oil and about 50ml of water to a blender, then blend until completely smooth and caramel-like.
In a large mixing bowl, combine the oats, gingerbread spice mix and salt.
Stir to evenly distribute the spices.
Pour the date caramel over the oats and mix until every piece is well coated.
Spread the mixture onto the prepared tray in a thin, even layer. Try not to overcrowd the tray — leaving space helps the granola crisp up beautifully.
Bake for 30 minutes.
After 20 minutes, remove the tray from the oven and gently break up the granola. Mix and scatter it again so it cooks evenly, then add the nuts.
Return the tray to the oven for the remaining 10–13 minutes.
Let the granola cool completely on the tray. This is when it becomes extra crunchy, so don’t skip or rush this step!
