Equipment

  • 9x13 Baking Dish
  • Large Bowl
  • Medium Bowl
  • Whisk or Handheld Mixer
  • Spatula

Ingredients
  

  • 1 1/2 Cups Milk
  • 1 Egg
  • 2 Teaspoons vanilla
  • 1/3 Cup Maple Syrup
  • 2 Tablespoons Melted Butter cooled
  • 1 cup Apple Sauce
  • 1 Apple peeled and shredded
  • 3 Cups Rolled Oats
  • 1/2 teaspoon salt
  • 1 teaspoon baking powder

Instructions
 

  • Preheat oven to 350 degrees.
  • In a medium bowl, whisk together the milk, egg, vanilla, maple syrup, melted (and slightly cooled) butter, applesauce, and shredded apple until fully combined.
  • Add the oats, salt, and baking powder. Mix well to combine.
  • Let the mixture rest for 5-10 minutes while you grease the 9x13 baking dish. This is optional, but it allows the oats to absorb the liquid and helps give the oatmeal a more creamy and custardy consistency.
  • After the mixture has rested, add the mixture to the prepared 9x13 pan.
  • Bake for 30-35 minutes, until the edges are slightly golden and the middle is set.
  • Let cool for 10-15 minutes before slicing and serving. This helps it set up and makes for easier slicing.
  • Enjoy!

Notes

Storage Tips
  • Let the baked oatmeal cool completely.
  • Store leftovers in an airtight container in the refrigerator for up to 4–5 days.
  • For easy grab-and-go breakfasts, slice into portions before storing.
Freezing Tips
  • This baked oatmeal freezes well.
  • Once cooled, slice into individual servings and wrap tightly or store in a freezer-safe container.
  • Freeze for up to 2 months.
  • Thaw overnight in the refrigerator or reheat directly from frozen.
Reheating Tips
  • Microwave: Heat individual slices for 30–60 seconds, adding a splash of milk if needed to keep it soft and creamy.
  • Oven: Reheat in a 325°F oven for 10–15 minutes, covered with foil to prevent drying out. Tip: A little extra milk on top before reheating brings back that fresh-from-the-oven texture ✨
Add-Ins & Variation
This baked oatmeal is easy to customize with what you have on hand! Some of my recommendations:
  • Nuts: Add ½ cup chopped walnuts or pecans for a classic banana bread feel.
  • Spices: Add a pinch of nutmeg for warm, cozy flavor.
  • Protein boost: Stir in 1–2 tablespoons ground flaxseed or chia seeds.
  • Dairy-free: Use almond milk, oat milk, or coconut milk and dairy-free chocolate chips.
