Flourless Blueberry Oatmeal Muffins

The flavors in these healthy, flourless blueberry oatmeal muffins are reminiscent of lemon poppy seed muffins, but extra wholesome. I’ve created both a vegan and non-vegan option here, using a “flax egg.” Both work well, but with the flax egg you have to be sure to let the muffins cool completely for breaking into them, otherwise they will be gooey. Enjoy your tasty breakfast treats!

These Flourless Blueberry Oatmeal Muffins Are:

  • Easy
  • Delicious
  • Freezer-friendly
  • Flourless
  • Filling
  • Healthy
  • Great on-the-go

To prevent your muffins from sticking, try these awesome, reusable silicone baking cups.

Useful Equipment

Instructions
 

Vegetarian Version

  • Preheat the oven to 375° F.
  • In a medium sized bowl, mash the banana and mix in the egg. Mix in the rest of the ingredients, gently stirring in the blueberries at the end.
  • Lightly grease muffin tins or line with muffin liners. Make 6 muffins, filling the tins almost to the top with batter.
  • Bake for 18-20 minutes, or until lightly browned.
  • Remove the muffins from the oven and allow to cool completely.

Vegan Version

  • In a small bowl, stir together the flax seed and water and let stand for a few minutes to thicken.
  • In a mixing bowl, add the bananas and nut butter and mash it all together until smooth using a fork or potato masher.
  • Stir in the flax "egg" and the rest of the ingredients, saving the blueberries for last and gently folding them in.
  • Lightly grease muffin tins or line with silicone muffin liners. Make 7-8 muffins, filling the tins to the top with batter.
  • Bake for 20-25 minutes, until browned.
  • Turn off the oven and let them sit in the warm oven for at least 30 minutes.
  • Remove the muffins from the oven and allow to cool completely.

Notes

  • It is important to let these muffins cool before eating. If you break into them early they will be gooey inside. They need time to internally finish cooking and set for the best texture. I know it’s hard to wait!
  • When the muffins are completely cool, they can be stored in an airtight container for a few days, or frozen.
  • The serving size for this recipe is 2 muffins for a lighter breakfast, or 3 muffins for a more filling breakfast.

  4. Hi Katie. Will regular rolled oats work for this (no instant on hand)?

    • Yes, but the texture will be better if you pulse them in a blender or food processor a few times to chop them into smaller pieces. That’s all instant oats are. They will be more absorbent that way, which is better for baked goods.

  10. Hi Katie, can you use unsweetened applesauce in place of the bananas? If so how much applesauce?

    • I’ve never tried it so I’m not sure, but I’d try swapping it out one for one, maybe a little less because applesauce is a bit wetter than mashed banana. I might also add a little bit of natural sweetener like honey, as applesauce isn’t as sweet as bananas.
