Preheat the oven to 180 degrees Celsius (350 degrees Fahrenheit). This will help the granola bake evenly.
Lightly grind the peanuts, raisins, and dates until you get a paste. This will help the flavors combine and make the granola crunchier.
In a large bowl, combine the rolled oats, stevia, cinnamon, and vanilla. This will create the base of the granola.
With your hands, form the mixture into large crumbs. This will help the granola bake evenly and give it a more attractive appearance.
Place the crumbs on a baking sheet lined with parchment paper. This will help the granola bake evenly and make it easy to clean up.
Bake for 20-25 minutes, or until the granola is golden. Watch the granola during baking to prevent burning. Let it cool completely before serving.
This will help the granola harden and achieve a crunchier texture.
