This Orange-Walnut Oatmeal Mini Muffin recipe is a marriage of the Orange Cake my grandmother had in her handwritten cookbook (with notes that it was my grandfather’s favorite), and an Oatmeal Muffin Recipe I found in a vintage McCall’s cookbook.  The “zippy” flavor of the orange zest used in this recipe, along with the richness of the plenitude of walnuts, seemed perfect for mini-muffins.  Enjoy!

  • 1 cup old fashioned oats
  • 1 cup buttermilk

  • ¼ cup oil canola or vegetable
  • 1 cup flour

  • ½ cup confectionery sugar for glaze


  • Preheat oven to 350 degrees, and flour the mini-muffin pan.

  • Put oats, buttermilk, orange juice, salt, vanilla & cinnamon in large mixing bowl, stir and set aside, while doing other prep work, so oatmeal can absorb some of the liquid.

  • Zest the entire orange, make sure the pieces are not too long, chop if necessary. Add to oatmeal mixture.

  • Add egg, sugar, and oil to mixture and beat well.

  • Mix the flour and baking powder in separate bowl, them add to oatmeal mixture.

  • Add the chopped walnuts last. Stir well to make sure they are evenly distributed.

  • Scoop up 1 tbs. of mixture, and place in each muffin tin.

  • Bake 14-16 minutes, until pick pulls clean from center, and edges are starting to show a little color.

  • Once cooled. Mix the confectionery sugar, and about a tbs of orange juice ( a little more will likely be needed). Brush over the muffins.


This recipe makes approx. 36 mini-muffins. Serving size 3 pieces.
