Preheat your oven to 375 F (190 C).
Butter a 9″ x 13″ (23 cm x 33 cm) mold, then line it with parchment paper.

In a bowl, combine the flour, coffee powder, salt, and cinnamon.

Cream the butter and sugars and beat for 3 minutes or until the mixture is light and creamy, then add the vanilla.
Add the dry ingredients and mix until they are almost incorporated.
Add the chocolate chips and mix just enough for the dry ingredients to disappear.
Press the dough into the prepared mold, pressing down well with your hands.

Bake for 20-22 minutes until the crust is golden brown.
Remove the mold from the oven and turn off the oven.

Sprinkle the chopped chocolate over the warm crust and return the crust to the oven for 2-3 minutes until the chocolate is melted.
Remove from the oven and spread the melted chocolate evenly with a spatula.
Sprinkle immediately with caramel bits and let cool before cutting into bars.
