Coarsely chop the pecans and set aside in a medium bowl.

In a large mixing bowl, cream softened butter and brown sugar until light and fluffy, about 2-3 minutes.

Gently fold the chopped pecans into the mixture until evenly incorporated.

Roll portions into bite-sized balls or form mini patties and place them on a parchment-lined baking sheet.

Chill the baking sheet in the refrigerator for 15-30 minutes to firm up the bites.

Melt chocolate in a microwave safe bowl, and drizzle it over each bite if desired.

Serve the Chocolate Pecan Turtle Clusters chilled or at room temperature, and store leftovers in an airtight container.
