Key Ingredients

Ingredients for the vegan banana oatmeal muffins laid out and labeled on a light background.
  • Bananas – the riper, the better! Not only do they provide sweetness and moisture, they also help to bind the batter.
  • Oat flour is an allergen-friendly flour that makes these muffins hearty but still light. You can easily make your own with a food processor and rolled oats.
  • Ground flaxseed mixed with water acts as a “flax egg”, a vegan egg substitute in baking.
  • Chocolate chips is the final piece of the puzzle that brings joy.

Hack It!

  • Swap the maple syrup for agave, date syrup, or another liquid sweetener.
  • Add nuts, seeds, or dried fruit in place of chocolate chips. Or, you know, as well as chocolate chips.
  • Any plant milk works for this recipe. If you have an allergy, pick one that is safe for you.
  • If you don’t have any ground flaxseed, chia seeds can also serve as the binding element in these banana oatmeal muffins.

Frequently Asked Questions

How do I store these muffins?

Keep them in an airtight container at cool room temperature for up to 5 days.

Are these muffins freezer-friendly?

Yes! Make sure that your muffins fully cool down, then freeze them in a freezer bag for up to 2 months. Just thaw naturally or microwave for 30-40 seconds until soft.

What is the difference between blending my oats and using ready oat flour?

In terms of the recipe, there is no difference. However, oats are typically cheaper to buy and more accessible. It’s also a great option if you don’t use oat flour often and don’t want to buy a whole bag for one recipe.

Do I have to adjust the recipe to make it gluten-free?

This recipe is naturally gluten-free, which is why I love using oats and oat flour. However, oats are often processed in the same factories as wheat and other grains containing gluten. If you have a serious allergy or an immune response, make sure to buy certified gluten-free oats or oat flour.
