Line an 8 x 8-inch baking dish with baking paper and set it aside.
In a microwave-safe bowl or on the stovetop, combine the unsweetened chocolate, almond butter, keto maple syrup, and optional coconut oil. Melt the mixture until it's well combined.
Add your preferred nuts or seeds to the mixture and stir until everything is fully combined.
Pour the chocolate mixture into the lined baking dish and spread it out evenly using a spatula.
Refrigerate or freeze the mixture until it becomes firm.
Once firm, slice the chilled mixture into chocolate bars. I made 20 bars from this recipe.
