Apple Crumble Muffins

First, preheat your oven to 350 degrees Fahrenheit. For the muffins, combine the 1/2 cup applesauce, 1/3 cup almond butter, 1/3 cup maple syrup, 1 teaspoon baking powder, 1 1/2 cups almond flour, 3/4 cup rolled oats, and 1 chopped apple. Mix until all ingredients are well combined. Divide the batter among muffin cups in a baking pan. For the crumble topping, mix together the 1 tablespoon softened vegan butter, 1 tablespoon coconut sugar, 1 tablespoon applesauce, 1/4 cup rolled oats, 1/4 cup almond flour, and 1 teaspoon cinnamon until a crumble texture forms. Sprinkle the crumble mixture evenly on top of the muffin batter in each cup. Bake for 25-30 minutes.
