I have been making these bars for 15 years. The original recipe came from Bon Appetit Magazine, and it was called Pumpkin-Chocolate Chip Loaf Cake. I liked the idea of baking this into bars instead of a loaf and topping with a drizzle of chocolate sauce. I have tweaked the recipe just a bit by swapping some of the white flour for white whole wheat, adjusting the spices and using coconut milk instead of regular whole milk.
