Vegan Gluten Free Apple Cider Muffins

0 Preheat oven to 350.
1 Add the coconut sugar, butter, apple sauce, apple cider and apple cider vinegar to a bowl and whisk to combine.
2 Add the remaining dry ingredients and whisk just until combined.
3 Divide the batter evenly in the muffin tin, filling each cup nearly full.
4 Make the streusel topping by adding the ingredients to a bowl and using a pastry cutter or two forks to create a crumble. Sprinkle on each of the muffins.
5 Transfer to the oven and bake for 10-12 minutes, until an inserted toothpick comes out mostly clean.
6 Let cool completely and transfer to a cooling rack.
7 If using, prepare the cinnamon glaze by combining the ingredients in a bowl with a fork. Drizzle over each muffin. Let the glaze harden and enjoy!
