In a medium bowl, combine the flour, baking powder and salt. Whisk to combine and set aside.
2 Cups All Purpose Flour, 2 teaspoon Baking Powder, ¼ teaspoon Kosher Salt
In a large bowl, combine the sugar, applesauce, non-dairy milk, melted vegan butter, lemon juice, lemon zest and vanilla. Whisk to combine.
¾ Cup Sugar, ⅔ Cup Applesauce, ½ Cup Non-Dairy Milk, 7 tablespoon Vegan Butter, melted and cooled, 1 tablespoon Lemon Juice, 2 teaspoon Lemon Zest, 1 teaspoon Vanilla Extract
Add the dry ingredients to the wet ingredients and whisk to form the batter (See Note). Add the blueberries and fold to distribute.
1 ¼ Cups Fresh Blueberries
Use a cookie scoop or a spoon to scoop the batter into the prepared muffin tin, filling each liner almost all the way full. Then, top each muffin with a scant tablespoon of streusel and gently press it into the batter so it sticks.
Bake the muffins in a 375* F oven for 19-22 minutes or until a toothpick inserted into the center of a muffin comes out clean. Allow the muffins to cool in the ban for about 5 minutes, then transfer to a wire rack to continue cooling.
