Soak bran flakes: In a small mixing bowl, combine 1 3/4 cups bran flakes and 1 cup buttermilk. Set aside to soak for 10 minutes.
Prepare and preheat: Preheat oven to 425°F. Spray a 12-count muffin pan with non-stick cooking spray, or use muffin liners.
Whisk dry ingredients: In a large mixing bowl, whisk together 1 1/2 cups flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, 1/2 teaspoon salt, and 1 1/2 teaspoons ground cinnamon.
Mix wet ingredients: In a small bowl, mix together 1 egg, 1/2 cup honey, 1/3 cup coconut oil, 1/3 cup applesauce, 1/2 cup brown sugar and 1 teaspoon vanilla.
Combine all ingredients: Add the wet ingredients and the bran flakes soaked in milk into the dry ingredients and whisk to combine. Do not over stir, just barely combine the ingredients.
Bake: Scoop into muffin cups using a large cookie scoop, filling almost to the top. Optionally, sprinkle 1/2 teaspoon brown sugar to the top of every muffin. Bake for 5 minutes, reduce to 350°F and bake 15 more minutes, until lightly golden.
Rest: Let cool 10 minutes before eating.
