In a large bowl, combine oats, cinnamon, nutmeg, allspice, sunflower seeds, almonds, coconut, and chocolate chips. Mix until combined, then set aside.
In a large bowl or a stand up mixer, combine the peanut butter, condensed milk, avocado oil, salt, and vanilla. Mix until smooth, then add in oat mixture about 1 cup at a time. Mix until combined.
Prepare a 9X13 baking dish or cake pan with parchment paper—draping it over the edges so it can easily be lifted out.
Press the oat mixture into the pan so that it is in one, even layer. Place on the center rack of the oven. Bake for 22-25 minutes, or until bars are firm and golden around the edges.
Allow bars to cook before cutting into squares or bars.
