Make acorn donut holes by dipping purchased donut holes in melted chocolate hazelnut spread, rolling in autumn sprinkles, and adding a pretzel stick stem.
Transfer the autumn-themed sprinkles into a small bowl (you can mix two varieties). Cover your workspace with wax paper to prepare for assembly.
In a deep, small microwave-safe bowl, warm the chocolate hazelnut spread or chocolate icing for approximately 15–20 seconds, until it is just melted. Submerge each donut hole halfway into the melted spread/icing, then roll it in the sprinkles. Push one pretzel half into the top of every 'acorn' and allow them to set on the wax paper.
