Prep: Line a baking sheet or large plate with parchment paper.
Crush the pretzels: In a small food processor, pulse the pretzel sticks a few times until they break into smaller pieces but are not ground completely into dust. If you don’t have a food processor, snap them into smaller pieces by hand or roughly chop them on a cutting board with a knife.
Mix: In a large bowl, stir the peanut butter, almond flour, pretzel sticks, maple syrup, and coconut flour until combined. The resulting mixture will be slightly sticky, with a dough-like feel.
Roll: Using your hands, roll the dough into balls roughly 1¼ inches in diameter and place them on the prepared baking sheet or plate. You should end up with 12 balls.
Chill (round 1): Transfer the baking sheet or plate to the freezer for 10 minutes.
Melt the chocolate: In a small bowl, melt the chocolate chips in the microwave on high in 30-second intervals, stirring after each interval. For me, this takes between 1 minute 45 seconds to 2 minutes. Alternatively, melt the chocolate chips in a small pot on the stove over low heat, stirring frequently.
Dip: Remove the balls from the freezer and dunk them one at a time into the melted chocolate, then return them to the baking sheet or plate. The bottom half will be coated in chocolate, with a round section of the peanut-butter-and-pretzel filling exposed at the top. Stop here if you prefer these treats to resemble traditional buckeyes. For all the chocolate lovers out there, keep going! Use a spoon to scoop chocolate over the top of each ball and smooth the edges.
Chill (round 2): Return the baking sheet or plate to the freezer for another 10 to 20 minutes to firm up. Serve slightly chilled or at room temperature.
