Preheat the oven to 350 degrees.
Blend together the gluten free flour, applesauce, sugar, baking powder, almond milk, vanilla and coconut oil to a mixing bowl until well combined.
Spoon the batter into a muffin tin lined with cupcake liners, filling them almost to the top.
Mix together the brown sugar and cinnamon.
Sprinkle the mixture over the top of the muffins.
Bake for 25 minutes, or until completely cooked through.
Let the muffins cool to room temperature.
Add the powdered sugar to a bowl, and whisk in almond milk slowly until a thickened glaze has formed.
Drizzle the glaze over the muffins before serving.
