  • 2 eggs (for the vegan option, use 2 flax eggs - 2 tbsp ground flaxseed whisked with 6 tbsp of water and set aside for 10-15 minutes)
  • 6 tbsp melted butter (for the vegan option, use vegan butter)
  • ½ cup 2% milk (for the vegan option, use plant-based milk - I used oat milk)
  • ¼ cup plus 2 tbsp coconut sugar
  • 1/4 cup unsweetened applesauce
  • ¼ cup honey (for the vegan option, use pure maple syrup)
  • 1 teaspoon pure vanilla extract
  • cup whole grain, gluten-free oat flour (I used Bob’s Red Mill)
  • 1/2 teaspoon cinnamon
  • ¼ teaspoon salt
  • 1 teaspoon baking soda


  • 2 tsp gluten-free oats (I used Bob's Red Mill)
  • 1 tbsp melted butter (for the vegan option, use vegan butter)


  • Preheat oven to 350° F.
  • Line a muffin tin with 12 baking cups. I recommend using parchment ones.
  • Whisk together eggs (or flax eggs), melted butter, milk of choice, coconut sugar, applesauce, honey (or maple syrup) and vanilla in a large bowl.
  • In a separate bowl, mix gluten-free oat flour, cinnamon, salt and baking soda.
  • Stir dry ingredients into wet ingredients.
  • Fill baking cups with batter until used up.
  • Top each muffin with gluten-free oats.
  • Using a pastry brush, coat the top of each muffin with melted butter.
  • Bake for 22-24 minutes until toothpick comes out clean.


Muffins can be stored in an airtight container at room temperature for up to 3 days or in an airtight container in the refrigerator for up to 5 days.
For the vegan version, the muffins will remain nut-free using a plant-based milk that is not derived from nuts as well as a vegan butter that is not derived from nuts.
