Preheat oven to 350 degrees. Prepare a cake or baking pan (11 x 7) with butter or cooking spray. Set aside.
Peel, core and thinly slice apples. Sprinkle apples with a light dusting of cinnamon if desired. I always do.
In a large bowl, combine oats, flour, brown sugar, nutmeg, cloves and cinnamon. Stir until blended.
Cut in the cold butter until crumbly by using two forks or your fingers to do it.
Add pecans or walnuts, if desired.
Add about one third of the oat mixture across the bottom of the pan. Top with half of the sliced apples. Sprinkle with raisins, if using. Half of the caramels or caramel sauce.
Repeat. Add another third of oat mixture. Layer the remaining apples. Add raisins and remaining caramel sauce or caramels.
Top with remaining oats and pour a ¼ cup of apple juice or cider all across the top of the apple crisp.
Bake uncovered for 40 minutes or until apples are tender.
The thinner the apples are sliced the better and quicker this will cook. Depending on the apples and the time of year, this apple crisp may take 10 minutes longer to cook.
Remove from the oven and serve on individual plates or in bowls.
Serve warm with vanilla ice cream, whipped cream or more caramel sauce. Enjoy every bite!
