Preheat oven to 425* F and line a muffin tin with 12 paper liners.
In a medium bowl, combine flour, baking powder, baking soda, cinnamon, and salt. Whisk to combine
2 ⅓ Cups All-Purpose Flour, 1 ½ teaspoon Baking Powder, ½ teaspoon Baking Soda, 1 teaspoon Ground Cinnamon, ½ teaspoon Kosher Salt
In a large bowl, combine sugar, applesauce, melted vegan butter, non-dairy milk, and vanilla. Whisk to combine. Add the dry ingredients to the wet ingredients and whisk to form the batter to form the batter. Don't worry about lumps, here. They will bake out.
¾ Cup Granulated Sugar, ⅔ Cup Unsweetened Applesauce, 8 tablespoon Vegan Butter, Melted, ½ Cup Non-Dairy Milk, 1 teaspoon Vanilla Extract
Add the chopped peach and use a spatula to fold the peaches into the batter.
1 Large Ripe Peach, chopped into about ¼" pieces
Then, fill each muffin cup almost all the way to the top with muffin batter, and top with a scant tablespoon of streusel.
Bake the muffins in a 425*F oven for 5 minutes, then reduce the heat to 350* F and continue baking for 16-19 minutes or until a toothpick inserted into the center of the muffins comes out clean.
Allow to cool slightly, then serve.
