These amazingly moist muffins are not only delicious but surprisingly healthy, too.
Yields 18 muffins.
Preheat oven to 350 degrees Fahrenheit (180 degrees Celsius). In a large mixing bowl, whisk eggs, sugars, oil, applesauce, and extracts. Add in all the dry ingredients. Mix well.
Fold in shredded apple and zucchini. Line a 12-cup and a 6-cup muffin tin with cupcake holders. Divide batter evenly among the cups.
If desired, mix streusel crumbs in a small bowl and sprinkle generously over muffins.
Bake for 30–35 minutes, until lightly brown.
Freeze any extra crumbs for future use.
