Delicious gluten free apple cinnamon muffins made with oat flour, hearty bites of apple, and zero refined sugar! The perfect snack or on-the-go breakfast.



For the muffins:

  • 1 cup milk of choice
  • ½ tbsp apple cider vinegar 
  • ¾ cup coconut sugar
  • 1 large egg
  • 1 (4.4 oz) container siggi’s 4% vanilla (about ½ cup)
  • 1 tsp vanilla
  • 2 + ¾ cup oat flour
  • ¼ cup ground flax seeds
  • 1 tbsp cinnamon
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp sea salt
  • 1 large apple, peeled and diced into bite size pieced 

    For the cinnamon maple crumble topping:

  •  1 cup almond flour
  • 2 tbsp pure maple syrup
  • 1 tbsp coconut sugar
  • ½ tsp cinnamon
  • Pinch of sea salt


  1.  Preheat oven to 350°F and line a muffin tin (you can bake this in separate batches if your muffin tin does not hold 15).
  2. Whisk milk, apple cider vinegar, coconut sugar, egg, yogurt, and vanilla in a bowl. Set aside.
  3. In a separate large bowl, stir together the oat flour, flax seed, cinnamon, baking powder, baking soda, and sea salt until everything is well combined. 
  4. Pour the wet ingredients into the dry ingredients and stir again until combined. Fold in apple pieces.
  5. Next, make the cinnamon crumble topping by combining almond flour, maple, coconut sugar, cinnamon, and sea salt until crumbly. 
  6. Scoop batter evenly among 15 cupcake liners (I like to use a cookie scoop here). Sprinkle cinnamon crumble over the top and bake for 20 minutes. Allow to cool on a cooling rack before enjoying.
