01 - Preheat the oven to 350°F. Line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup.
02 - In a mixing bowl, beat the softened butter, brown sugar, and honey together until light and fluffy, approximately 2-3 minutes.
03 - Add the oats, chopped pecans, crystallized ginger, cinnamon, nutmeg, and salt to the butter mixture. Stir until all ingredients are evenly distributed.
04 - Drop rounded tablespoonfuls of dough onto the prepared baking sheet, leaving approximately 2 inches of space between each cluster to allow for spreading.
05 - Bake for 12-15 minutes until edges turn golden brown. Remove from oven and allow clusters to cool completely on the baking sheet to maintain structural integrity.
06 - While clusters cool, whisk together powdered sugar, milk, and vanilla extract until smooth and thick but pourable.
07 - Drizzle or spread frosting generously over each completely cooled cluster. Allow frosting to set for 10-15 minutes before serving.
