In a small bowl, combine all crumb topping ingredients and set aside.
Preheat oven to 425℉ and spray a 12 cup muffin pan with cooking spray; set aside.
In a small bowl, combine milk & vinegar; set aside.
In a medium bowl, beat eggs and then stir in applesauce, sugar, vanilla and the almond milk/vinegar mixture.
In a separate large bowl, combine Kodiak Cakes Pancake Mix, baking powder, cinnamon, allspice, cloves and salt. Toss in the grated apple.
Pour the wet ingredients into the dry and mix with a big spoon, just until combined (a few lumps are ok). Do NOT overmix. The batter will be thick. Divide the batter evenly between the 12 muffin cups.
Top each muffin evenly with the crumble topping and bake muffins for 4 mins at 425℉ then immediately lower oven temperature to 375℉ and bake for 10-11 mins more, or until a toothpick inserted in the center comes out clean.
Remove and allow to cool for a few minutes before removing the muffins from the tin. Use a butter knife around the edges, as needed, to coax the muffins out after about 5-10 minutes. Place on a cooling rack to cool completely.
If you have leftover muffins, store them, covered, at room temperature for up to 2 days, or in the refrigerator for up to 4 days. Freeze leftover muffins for up to 3 months.
