Preheat the oven to 425℉/218℃. Line a muffin tin with 12 liners and set aside.
In a bowl, add the flour, baking soda, baking powder, cornstarch, cinnamon, cloves, allspice, and salt. Stir to combine and set aside.
2 cups all-purpose flour, 1 tsp baking soda, 1 1/2 tsps baking powder, 1 1/2 tsp cinnamon, pinch of cloves, pinch of allspice, 2 tsp cornstarch, 1/4 tsp salt
In a large bowl, add brown sugar, white sugar, and oil. Whisk together.
2/3 cups dark brown sugar, 1/3 cup white sugar, 1/2 cup oil
Then add in applesauce, eggs, and vanilla. Whisk until smooth (1-2 minutes).
1 cup unsweetened applesauce, 2 large eggs, 1 tbsp vanilla
Add the dry and wet ingredients together. With a spatula, gently mix just until a soft muffin batter forms. Do not over-mix!
Mix in the mini chocolate chips a few times just until evenly distributed - do not over-mix! Let the batter rest for 10 minutes.

Scoop the muffin batter into the liners evenly, filling them up to the top. Sprinkle chocolate chips and white sugar on top (optional, but recommended).
Bake for 5 minutes at 425℉, then lower the temperature to 350℉/176℃ and continue baking until a toothpick inserted in the middle comes out clean.
Allow the muffins to cool, and enjoy!
