Step 1

Preheat oven to 425°F. Lightly grease a 12-count muffin tin with non-stick cooking spray or line with paper liners. Set aside.

Step 2

In a large bowl, combine the flour, white sugar, brown sugar, baking powder, cinnamon, nutmeg, and salt.

Step 3

In a medium bowl, whisk the egg, milk, applesauce, and vanilla bean paste (or extract) in a medium bowl until thoroughly combined.

Step 4

Slowly incorporate the wet ingredients into the dry ingredients and mix until just blended. Gently fold in diced apples. Spoon batter into prepared muffin tins, filling each cup about 3/4 full.

Step 5

To make the streusel topping, combine the brown sugar, white sugar, cinnamon, melted butter, and flour. Stir well until it resembles wet sand. Sprinkle over tops of muffins.

Step 6

Bake for 5 minutes at 425°F, then, without opening oven door, lower temperature to 375°F and bake for about 10-15 minutes, or until toothpick inserted into center of muffin comes out clean. Baking at 425°F first helps to achieve that high, bakery-style muffin. Remove from oven and let cool.
