  • 2 cups rolled oats (gluten free, if needed)
  • 1 1/2 tsp. cinnamon
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 2 cups milk (I use almond milk, but any dairy or non-dairy milk will work)
  • 1/3 cup pure maple syrup
  • 1 egg (or 1 Tbsp chia seed/flax seed, as directed below)
  • 2 Tbsp. melted butter, vegan butter, or coconut oil (optional)
  • 1 1/2 tsp vanilla
  • 1/2 cup sliced strawberries (+23 Tbsp. for the top)
  • 1/2 cup raspberries (+23 Tbsp. for the top)
  • 1/2 cup blueberries (+ 23 Tbsp. for the top)


  1. Preheat oven to 375 degrees. Grease a 2-quart baking dish (like an 8×8″ or 9×9″ pan)
  2. In a large bowl, combine your dry ingredients–oats, cinnamon, baking powder, and salt. Stir to combine.
  3. Then, add the wet ingredients. Add milk, syrup, egg or chia egg, melted butter/oil, and vanilla to the dry ingredients and stir until combined.
  4. Fold in strawberries, raspberries, and blueberries (reserve a few tablespoons of each to sprinkle on top, if you like).
  5. Pour mixture into your prepared baking dish. Sprinkle with remaining berries
  6. Bake at 375 degrees for 35-40 minutes, or until the oatmeal has plumped and the top is golden.
  7. Remove from oven and let stand about 5 minutes before slicing or scooping.


To make a flax or chia egg: combine 1 Tbsp ground flaxseed OR 1 Tbsp chia seeds with 3 Tbsp water. Allow to sit for 5-7 minutes to activate/gel before adding to the other ingredients.
