Preheat oven to 200°F. Pour honey in a small skillet and add lemon slices in a single layer. Bring to a boil over medium heat. Reduce heat and simmer for 15 to 20 minutes, turning slices occasionally. Remove from heat; reserve syrup. Place slices on a parchment-lined cookie sheet and bake 10 minutes. Turn slices and bake an additional 10 minutes or until slices are dry. In a mixing bowl, cream butter until light and fluffy. Add 2 cups of powdered sugar; mix well. Slowly add cooled reserved syrup and lemon juice and zest; mix well. Add remaining powdered sugar; beat well.

*Any mild-flavored honey such as Clover may be used.
