*Note: If you have nut allergies, or prefer not to use the nuts, sunflower seeds make a good substitute. I had great success using the same amount of sunflower seeds in the crust, and using sun butter in the caramel (although whole sunflower seeds would work here too, just blend well.). Omit the almond extract from the caramel. And while I haven't tried it, I think hemp seeds would also work well. If you try them, let me know!
