Preheat oven to 350*. Line a muffin tin with 12 paper liners.
In a large bowl, combine sugar, applesauce, non-dairy milk, melted vegan butter and vanilla. Whisk well to combine.
¾ Cup Granulated Sugar, ⅔ Cup Applesauce, 7 tablespoon Vegan Butter, melted, 2 teaspoon Vanilla, ½ Cup Non-Dairy Milk
Into the bowl, add flour, baking powder, and salt. Whisk just until the batter forms.
2 Cups All-Purpose Flour, 2 teaspoon Baking Powder, ¼ teaspoon Kosher Salt
Add chopped blackberries and fold gently with a rubber spatula just until the berries are evenly distributed.
1 ¼ Cup Blackberries, roughly chopped
Scoop the muffin batter into a lined muffin tin using and ice cream scoop or a spoon. Fill each cup almost all of the way full. Then sprinkle a scant tablespoon of crumb onto each muffin.
Bake in a 350*F oven for 24-26 minutes or until a toothpick inserted into the center of a muffin comes out clean.
Allow the muffins to cool in the tin for 10 minutes, then transfer them to a cooling rack. Serve.
