Add piloncillo/panela to a saucepan and add about 2 Tbsp of water and melt the sugar over low heat, stirring often (this takes at least 10 minutes). Once almost melted, add butter to melt, too.
Put 1 cup oats into a blender or small food processor and process until you have fine flour.
Add 2 cups whole oats and oat flour to a big bowl.
Add nuts, seeds, and spices.
Once sugar and butter are all melted, add vanilla and whisk until well combined.
Pour sugar/butter mixture over dry ingredients and mix well until all dry ingredients are wet.
Spread out on a large baking sheet lined with parchment paper (important!) and pop in the oven for 20 minutes.
Take out of the oven, add raisins and stir well. Return into the oven for another 20 minutes.
Take out and let cool down completely before touching, then break into big clusters.
