Blueberry & Almond Flourless Oatmeal Muffins

The flavors in these healthy, flourless breakfast treats are reminiscent of lemon poppy seed muffins. These are similar to Baked Oatmeal Cups, but the difference is that the egg in this recipe makes a wetter, richer batter that works better in muffin tins. The texture is less dense than when using only nut butter as a binder.

These Flourless Oatmeal Muffins Are:

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

Prep Time: 10 minutes
Cook Time: 20 minutes
Servings: 3
Recipe From: Katie’s Conscious Kitchen



  • 3/4 cup instant oats, dry 3 oz


  • 1 egg
  • 1/4 cup nut butter 2 oz
  • 1/4 cup nuts 2 oz
  • 2 tsp nut butter, per serving as a topping 1/3 oz


  • 2 bananas, mashed 8 oz
  • 1 cup blueberries, fresh or frozen 6 oz


  • 1 tsp baking powder
  • 1/2 tsp cinnamon
  • 1/2 tsp almond extract
  • 1/2 tsp vanilla extract
  • 1/2 tsp lemon zest optional
  • 1/2 tsp black poppyseeds optional
  • 1/4 tsp good quality sea salt

Suggested Equipment*


  • 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.
  • Allow them to cool for 5-10 minutes after removing from the oven.
  • When the muffins are completely cool, they can be stored in an airtight container for a few days, or frozen.


  • To make this breakfast gluten-free, be sure to use certified gluten-free oats. Oats are a naturally gluten-free grain, but are often processed with products containing gluten and this contamination can be enough to trigger an immune response in those with high gluten sensitivity or celiac disease. 
  • The serving size for this recipe is 2 muffins for a lighter breakfast, or 3 muffins for a more filling breakfast.

    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.
