Servings: 9 squares


  • 3 cups old fashioned oats
  • 1 1/2 cups milk or milk alternative I prefer oat or almond milk!
  • 1/4 cup honey optional
  • 2 large eggs
  • 2 tsp baking powder
  • 1 tsp vanilla extract
  • 1 tsp cinnamon
  • 1/4 tsp salt
  • 1 cup chopped walnuts
  • 1 cup fresh or frozen blueberries


  • Preheat oven to 350 degrees Fahrenheit. Line an 8x8 baking dish with parchment paper.
  • In a large bowl, mix milk, eggs, honey, baking powder, vanilla, salt, and cinnamon.
  • Add oats, chopped walnuts, and blueberries. Stir gently to combine.
  • Pour into 8x8 and bake 30-40 minutes until a toothpick inserted in the center comes out mostly clean.
  • Let cool slightly before slicing into 9 squares. Add a drizzle of honey and any other desired toppings (more walnuts, perhaps?) and enjoy!
  • Store in an airtight container in the fridge for up to a week. Enjoy cold or reheated!
