In a mixing bowl, combine the almond butter, almond flour, stevia, sugar-free syrup, and optional cinnamon. Mix well until all ingredients are fully incorporated and a dough-like consistency forms.
If the mixture is too sticky, add a bit more almond flour until you reach a manageable consistency that is easy to roll into balls.
Using a cookie scoop or tablespoon, portion out the mixture and roll it into small balls, about 1 inch in diameter. Place each truffle on a baking sheet lined with parchment paper.
Refrigerate the truffles for about 30 minutes to firm them up. This step is crucial as it makes the truffles easier to coat in chocolate later on.
While the truffles are chilling, melt your sugar-free chocolate in a microwave-safe bowl or double boiler until smooth. Be careful not to overheat the chocolate; stir it gently as it melts.
Once the truffles are firm, dip each one into the melted chocolate, ensuring they are fully coated. Use a fork to lift them out and allow any excess chocolate to drip off before placing them back on the parchment-lined baking sheet.
Place the coated truffles back in the refrigerator for another 15-20 minutes to allow the chocolate to set.
Once the chocolate has hardened, your Almond Butter Truffles are ready to enjoy! Store any leftovers in an airtight container in the fridge.
