If you're not allergic to tree nuts, too, consider making these with almond butter, cashew butter, or walnut butter. For a nut-free solution, try sunflower seed butter. Instead of dry-roasted nuts, trade in chopped toasted walnuts or even broken pretzel pieces. While the latter peanut substitute will taste a lot different from a classic Snickers bar, it's still delicious. Think of it as similar to a Take 5 bar!
