Preheat the oven to 350℉ and set the rack to the middle position.
Spray or grease a 10-inch cast iron pan with oil.
Mix the apricots, cranberries, pecans, chocolate chips, and coconut together in amixing bowl and set aside.
In a separate large mixing bowl, beat the olive oil, eggs, vanilla, peanut butter, and brown sugar until light and fluffy, about 3 minutes. Add in the flour, baking soda, most of the salt (reserve a generous pinch to sprinkle over the top), and oats. Mix everything well for about three more minutes to combine.
Add about 1/3 of the dough to the bottom of the prepared pan. Press it down to cover the bottom evenly.
Add the fruit and nut mixture to the cookie dough. Use a spatula to mix everything well.
Top the pan with the rest of the cookie dough and gently press (using damp fingers if necessary) dough evenly over the pan. Sprinkle the remaining pinch of salt over the top of the cookie dough.
Bake for 15-20 minutes, or until a toothpick inserted in the middle comes out clean. Serve warm.
Notes
For a chewy cookie, do not overbake.Feel free to use any combination of fruit and nuts you prefer.If your skillet is larger or smaller than 10 inches, adjust the bake time accordingly. A larger skillet will make a thinner dough, which will bake faster. A smaller skillet will make a thicker cookie, which may take longer to bake.If desired, top the cookie with ice cream.
