Preheat the oven to 350 degrees and lightly coat two 8 inch pans with cooking spray.
Combine the flour, sugar, baking soda and powder, salt, and spices. Add the pumpkin, oil, applesauce, eggs and vanilla. Mix until combined, scraping the bowl as necessary.
Divide the batter evenly into the prepared pans.
Melt the butter then stir in the brown sugar, cinnamon and pecans. Spoon this mixture down the middle of each loaf.
Bake for 35 minutes. Cool in the foil pan for 10 minutes then transfer to a wire rack to cool completely. Store covered.
Notes
I found the very middle of the loaf had absorbed a lot of the topping and it was a little goopy aka more delicious in my opinion. If you like, cut the topping amounts in half.
