Blueberry steel cut oat muffins

Wholesome blueberry steel-cut oat banana breakfast muffins are simple to bake, healthy and easily gluten free, naturally sweetened and totally adaptable!

I whipped up these absolutely delicious and healthy bakery-style muffins that will be sure to impress your taste buds while making you feel satisfied at the same time. The secret ingredient is steel cut oats; soaked overnight in milk (or water) which helps give this high fiber treat an extra dose of filling nutrients like protein, calcium, magnesium & iron. After just one serving our bodies can immediately start reaping all their benefits.

This muffin is naturally sugar-free, sweetened with honey and extra ripe bananas. They come together thanks to the pre-soaked steel cut oats making them moist and filling. This has been a favorite in my household! It wasn't long at all before they were gone, so I already have another batch in the oven as I create this blog post. We also love variations of this recipe like my Peach apricot steel cut oat breakfast muffinsMaple Pumpkin steel cut oat breakfast muffins or classic Gluten free steel-cut oat banana breakfast muffins

Tips for preparing to bake these gluten free steel-cut oat banana breakfast muffins:

Soak your steel cut oats overnight in water or milk. This will create a super thick batter, allowing your muffins to rise into bakery-style muffins. No dry muffins here! This adds such a good, hearty texture. This step is necessary, as you want the oats to absorb the liquid. I've tried to simply skip this step and heat the oats before, but it results in a less than desirable texture in the muffin. Don't skip this step!

Blueberry steel cut oat muffins

Yield: 12 muffins


  • 115 g - ½ cup unsalted butter
  • 3 ripened bananas, mashed
  • 1 cup fresh blueberries
  • 240ml -1 cup milk or water
  • 1 large egg, at room temperature
  • 1 teaspoon pure vanilla extract
  • 120 ml ½ cup honey

  • 156 g - 1 and ¼ cups gluten-free flour
  • 1 teaspoon baking powder

    4. Pour your melted butter + honey combo, egg, vanilla, mashed banana, and soaked oats in with your dry ingredients. Your oats should have absorbed your milk or water.

    6. Using an ice cream scoop, scoop your muffin batter into your lined muffin pan. The batter should reach the top of the liner. If desired, add old fashioned oats on top for garnish. for more texture.
