  • Total Time1 hour
  • Yield6 1x
  • DietVegetarian

Ingredients

Units Scale
  • 2 cups rolled oats (use certified gluten-free if needed)
  • 1 tsp baking powder
  • 1/2 tsp ground cinnamon
  • 2 large eggs
  • 1/4 cup maple syrup
  • 2 tsp vanilla extract
  • 1/4 tsp sea salt
  • 1/4 cup melted unsalted butter
  • 2 cups milk (I use cashew or almond milk)
  • 1 cup diced peaches, fresh or frozen (plus 1 fresh sliced peach for garnish if desired)
  • 1 cup blueberries, fresh or frozen (plus more for garnish if desired)
  • A knob of butter
  • 1-2 tbsp turbinado sugar (optional)

Instructions

  1. Preheat your oven to 375°F and prepare a 12x8-inch baking dish or similar.
  2. In a medium bowl, whisk together rolled oats, baking powder, and ground cinnamon. Set aside.
  3. In a large bowl, whisk eggs, maple syrup, vanilla extract, and sea salt.
  4. Whisk in melted butter. Make sure the butter isn’t too hot so it doesn’t cook the eggs.
  5. Add milk and whisk again.
  6. Add the dry ingredients to the wet ingredients and whisk or stir to combine.
  7. Fold in diced peaches and blueberries.
  8. Use a small knob of butter to grease your prepared baking dish and pour the batter into it, spreading the oats and fruit evenly.
  9. Garnish with your reserved fresh, sliced peach and more blueberries, and sprinkle with turbinado sugar if desired.
  10. Bake in the preheated oven for 45-50 minutes or until golden brown around the edges.
  11. Allow to cool for 5-10 minutes and slice into 6 squares.
  12. Serve warm on its own or with toppings. Enjoy!

Notes

Refrigerator: Store the oatmeal in an airtight container in the fridge for up to 3-4 days. If you’re stacking the slices, place a piece of parchment paper between the slices.

Freezer: Store the oatmeal portioned in a freezer-safe container or a freezer bag. Place a piece of parchment paper between your slices to prevent them from freezing together.

Reheating: Reheat the oats in a preheated oven at 300°F on a small baking sheet for 10-15 minutes. If frozen, defrost in the fridge overnight first, or reheat from frozen for 20-30 minutes.
