Creating these delightful Pumpkin-Applesauce Muffins is a straightforward process. Follow these steps for perfect results:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or grease it lightly.
2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, whole wheat flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
3. Combine Wet Ingredients: In another bowl, mix the pumpkin puree, applesauce, granulated sugar, brown sugar, eggs, vegetable oil, and vanilla extract until well combined.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring gently just until combined. Avoid overmixing to keep the muffins tender.
5. Add Optional Ingredients: If desired, fold in chopped nuts or chocolate chips for added texture and flavor.
6. Fill Muffin Tin: Divide the batter evenly among the prepared muffin cups, filling each about two-thirds full.
7. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
8. Cool: Remove the muffins from the oven and let them cool in the pan for about 10 minutes. Transfer to a wire rack to cool completely.

By following these steps, you’ll create a batch of delicious Pumpkin-Applesauce Muffins that are sure to impress!
