Preheat oven to 350 degrees. Spray a 9 x 13" baking pan with a good coat of PAM.
Combine the dry ingredients in a medium bowl and set aside.
Melt butter in microwave or on stove top.
Add the melted butter to dry ingredients and mix with hands until the mixture looks crumbly.
Take half of the mixture and press it into the bottom of a greased baking pan. Press the mixture down to make an even, flat layer.
Bake bottom layer for 8-10 minutes, or until it starts to turn brown on the edges
Once you take it out of the oven, immediately spread the chocolate chips on top of the warm layer. Make sure they are distributed evenly.
Then add the squeeze caramel. There is no real measurement. Just put a nice even coat on top of the chips without drowning them all. It should look something like the image above.
Add the other half of the crumble mixture to cover the filling. Pat it down gently to pack in the filling.
Bake for another 25-30 minutes or until the edges turn brown.
Set aside to cool. Let Jumbles cool completely before cutting.
