Almonds, peanuts, cashews, hazelnuts, and pecans are the most commonly used nuts in dark chocolate snacks.
Typical fillings include peanut butter centers, cashew butter centers, hazelnut butter, and combinations such as caramel-peanut nougat.
They come as bars, bite-sized pieces, trail mix blends, and peanut butter cups.
They commonly avoid artificial colors, artificial sweeteners, artificial flavors, refined sugar or cane sugar, palm oil, sugar alcohols (e.g., erythritol), soy/soy lecithins, and other preservatives or fillers.
Common mix-ins include dark chocolate-covered coffee beans, chocolate chips, praline almonds, and mocha-flavored pecans.
