Cinnamon Sugar Oat Flour Muffins

Servings 12
Prep Time 20 minutes
Cook Time 25 minutes
Total Time 45 minutes


For the Muffins

  • 2 cups oat flour
  • 1 tbsp cinnamon
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup unsweetened applesauce
  • 1/2 cup pure maple syrup (or honey)
  • 1/3 cup plain yogurt (I use dairy free)
  • 1/3 cup water (or milk of choice)
  • 1/4 cup coconut oil, melted (or olive oil)
  • 1 tsp pure vanilla extract
  • 2 eggs (flax or regular eggs)

For the Cinnamon Sugar Topping

  • 2 tsp cinnamon
  • 2 tbsp coconut sugar
  • 1 tbsp coconut oil (or olive oil)


  • Preheat the oven to 350°F and line a 12 cup muffin pan with paper liners. Gently spray the liners with cooking spray. If omitting the liners, simply spray the muffin pan with cooking spray.
  • While the oven is preheating, add the dry ingredients for the muffins to a large mixing bowl and whisk together. Then add all of the wet ingredients for the muffins to the dry ingredients. Once the wet ingredients are added, whisk everything together until the batter is smooth and well combined.
  • Scoop the batter into the prepared muffin pan, filling each muffin liner equally with batter. Bake the muffins for 25 minutes, or until a toothpick inserted in the center comes out clean. Then let the muffins cool in the muffin pan.
  • While the muffins cool, prepare the cinnamon sugar topping: mix together the cinnamon and coconut sugar in a small dish. In a separate small dish, add the coconut oil. Heat the coconut oil in the microwave until melted.
  • Once the muffins have cooled slightly, gently brush the tops of the muffins with melted coconut oil. Then roll the tops of the muffins in the cinnamon sugar mixture. Allow the muffins to cool completely before storing.
