Preheat oven to 375 degrees.
Unwrap caramels, and cut each one into 4 small pieces. Set aside.
Wash apples, and remove seeds/core using an apple corer slicer or knife. Cut into ½" small pieces, place into a bowl, and squeeze some lemon juice on the pieces if you are not baking right away to keep them from browning. Set aside.
Soften 2 cubes (1 cup) of butter in the microwave for 1 minute on low heat.
In a large bowl, mix the dry ingredients. Combine melted butter, cinnamon, oats, flour, and brown sugar. Combine mixture until crumbly using a spatula or a pastry blender until all the ingredients are well incorporated.
Spray a large 9 x 13 glass baking dish, pan or large deep cast iron skillet with non-stick spray.
Sprinkle 3 cups of the crumble mixture into the bottom of the dish evenly. Press the crust flat with a measuring cup to the edges.
Next, layer ½ apples, and ½ cut pieces of caramels, and sprinkle 3 more cups of the crumbled crisp mixture on top.
Repeat the last layer with the other ½ apples, sprinkle the remaining crumble mixture on top. Decorate with the rest of the caramel pieces on top of the apples.
Bake 375 degrees for 45 minutes.
Serve with a big scoop of vanilla ice cream or whipped cream.
