Roast nuts by placing them on the baking sheet and bake for 10 minutes.
Beat the butter and sugar until creamy and smooth. Add egg and vanilla until combined.In a separate bowl whisk together the flour, baking soda, salt, cinnamon. Add the flour mixture to the creamed mixture till incorporated. Stir in oats, nuts, and raisins.
I prefer smaller cookies so I use a small ice cream scoop, place them on the baking sheet 1" apart, then pat them down with my fingers. Bake cookies for 11 minutes. Once they're done place them on a wire rack to cool, then keep in a cookie jar.
