Preheat oven to 325 degrees. Generously grease a 9″ loaf pan with cooking spray.
While oven is heating, combine dry ingredients (flour, Truvia, baking soda, baking powder, and salt) in a large mixing bowl. Stir to combine.
Add applesauce, yogurt, eggs, milk, pumpkin, and pumpkin pie spice to the dry mixture. Using a spatula, stir the wet ingredients into the mixture to moisten the dry ingredients.
When the mixture is partially combined, use an electric mixer. Mix on low until well combined.
Transfer the batter into the greased loaf pan and place in the oven.
Bake for 65-75 minutes, or until a toothpick can be inserted into the center and come out clean. Let the loaves cool in the pans for about 10 minutes, then turn out onto a wire rack to cool completely.
