  • 2 ½ cups rolled oats regular or gluten free
  • 1 ½ cup milk of choice
  • ¼ c butter, melted
  • cup brown sugar
  • 2 eggs
  • 1 tsp vanilla extract
  • 1 T cinnamon
  • 1 tsp baking powder
  • cup blueberries fresh or frozen
  • ½ tsp sea salt
  • ½ cup chopped pecans or walnuts


  • Preheat oven to 350° F.
  • In a mixing bowl, combine egg, butter, milk and vanilla and whisk well to combine. Add in the brown sugar and cinnamon and whisk.
  • In a separate bowl, combine baking powder, sea salt, and oats and stir to combine. Add them into the wet ingredients and stir to combine.
  • Stir in the blueberries and pecans.
  • Pour mixture into an 9x9 inch baking pan lined with parchment or greased with spray oil.
  • Bake for about 35 minutes or until the top is golden brown and all liquid is absorbed.
  • Allow to cool and serve with a drizzle of maple, butter, yogurt or extra blueberries on top. Store in the refrigerator for about 3-4 days and warm up before serving.


  • Fully cooked, this baked oatmeal will be set enough to even grab with your hands and hold. However, if you under cook it by about 5 minutes, it is great as well. I like to do this sometimes and then eat it with a spoon, broken up in little pieces over yogurt.
  • This baked oatmeal is not super sweet. If you want it on the sweeter side, you can add a touch more brown sugar. I like to add maple over top so I didn't want it to be overly sweet.
