Ingredients Method Notes

Ingredients
  

  • 2 cups rolled oats old-fashioned, not instant

  • 2 tbsp maple syrup or honey
  • 1 tsp vanilla extract
  • 1 ½ tsp ground cinnamon

  • 1 tsp baking powder
  • ¼ tsp salt
  • ⅓ cup chopped nuts walnuts, pecans, or almonds

Method
 

  1. Preheat oven to 375°F (190°C). Grease an 8x8-inch baking dish.
  2. In a large bowl, mix rolled oats, baking powder, cinnamon, nutmeg, salt, and half the chopped nuts.
  3. In another bowl, whisk together milk, eggs, maple syrup (or honey), and vanilla extract.
  4. Pour the wet mix into the dry ingredients. Stir gently until combined.
  5. Fold in the berries.
  6. Pour mixture into the baking dish. Sprinkle remaining nuts on top.
  7. Bake for 35–40 minutes, until edges are golden and the center is set.
  8. Let rest for 5–10 minutes before serving.

Notes

  • You can swap fresh berries for frozen without thawing first.
  • Almond, soy, or oat milk work just as well as dairy.
  • Store leftovers in the fridge for up to 5 days or freeze for up to 3 months.
  • For a sweeter version, drizzle extra maple syrup or honey when serving.
