Preheat the oven to 350F. Line a baking sheet with parchment paper.
In a large bowl, cream together the butter and the sugars until mixture is light. Beat in the eggs one at a time, followed by the vanilla extract.
In a medium bowl, whisk together the flour, baking soda, baking powder and salt. Gradually blend the flour mixture into butter mixture. Stir in the oats and dried fruits.
Drop 1-inch balls of dough onto the cookie sheet, placing about 1 ½ inches apart so they have room to spread.
Bake at 350F for 10-13 minutes, until cookies are just golden brown at the edges.
Cool on baking sheet for at least 1-2 minutes before transferring to a wire rack to cool completely.
