Ingredients

  • 1 cup old fashioned oats
  • 1 cup whole wheat flour
  • 1/2 teaspoon salt
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1/2 cup butter melted
  • 1/2 cup brown sugar
  • 1 cup buttermilk
  • 1/2 teaspoon vanilla extract
  • 1 cup blueberries
  • 1 egg beaten
  • 1/4 cup lemon juice about 1 lemon
  • 1 lemon zest

For The Glaze

  • 1/4 cup blueberries
  • 1 tablespoon buttermilk
  • 1 teaspoon vanilla extract
  • 1/2 lemon juice
  • 3/4 cup powdered sugar

Instructions

  • Preheat the oven to 375 F and line a muffin tin with muffin wrappers.
  • In a large mixing bowl, combine the oats and the buttermilk. Let them sit while you prep the other ingredients, or up to 30 minutes to soften the oats.
  • In another bowl, sift in the whole wheat flour, baking powder, baking soda, and salt.
  • Add the melted butter, brown sugar, egg, lemon juice, and zest, and vanilla extract to the oat mixture, stir until combined.
  • Add the flour mixture to the oat mixture and stir until just combined. Careful not to overmix them! Then fold in the blueberries.
  • Evenly divide the batter into a muffin tin. Bake for 15-20 minutes or until a toothpick comes out clean.
  • Place on a wire rack to cool, then drizzle with Lemon Blueberry Glaze.

For the glaze:

  • 1. Add the blueberries, lemon juice, vanilla extract, and buttermilk to a food processor or blender and mix on high until completely combined. Then transfer the mixture to a small mixing bowl using a strainer to catch any blueberry remains from the skin.*
  • 2. Whisk in the powdered sugar until completely combined. You can add more sugar to make the glaze thicker or more buttermilk to thin it out.

Notes

*If you don't have a food processor or blender, the blueberries can be muddled but make sure to mash them very well.
*The glaze can be made without a strainer if you don't have one, but it is recommended to catch the remains of the blueberry skin.
