Baking has always been my outlet, and while I do love making desserts, I try to bake sweet treats that are on the healthier side to keep sugar to a minimum.

Muffins are a go-to for me because they’re great for breakfast, snacks or any time I’m craving something sweet.

These Banana Oatmeal Muffins are almost always on repeat because they’re easy, delicious and much healthier than the average muffin.

Like my healthy zucchini muffins and healthy pumpkin muffins, they’re packed with whole grain oat flour, and there’s no dairy, gluten or refined sugar or oil in sight.

They’re also extremely easy to make, and they’re guaranteed to be a hit with everyone in the family. 🙂

Recipe ingredients

There are only a few simple, wholesome ingredients necessary for these fluffy banana oat flour muffins, most of which you probably already have on hand:

  • Bananas. Use very ripe, spotted bananas. The riper your bananas are, the sweeter your muffins will be.
  • Oat flour. Oat flour is a gluten-free, whole grain alternative to all purpose flour, and it lends a soft, tender crumb to the banana oatmeal muffins. You can purchase it or see my post on how to make oat flour to make it with rolled oats in your pantry!
  • Eggs. The eggs provide structure to the muffins.
  • Coconut sugar. The coconut sugar is unrefined and has a mild sweetness. Sub it with granulated, brown sugar or even maple sugar.
  • Oil. I love using olive oil or coconut oil, but you can use whatever you have on hand.
  • Almond milk. Sub with your favorite dairy or non-dairy milk.
  • Baking powder and baking soda. Essential for leavening.
  • Cinnamon. The cinnamon adds cozy warm flavor, but it’s completely optional.
  • Walnuts. I add walnuts to the top so they can toast as the muffins bake, and they add a nice crunchy texture. Sub with pecans or sliced almonds, or omit altogether.
