Delicious Apple Upside Down Baked Oatmeal

It’s time to level-up your healthy dessert with this apple upside down baked oatmeal. Enjoy this recipe alone as a healthy treat, a quick pre-workout snack, and also as a part of a balanced breakfast.

Ingredients in Apple Upside Down Baked Oatmeal


Let’s start with the most important part – the delicious apple upside down topping. This is a quick combo of some melted butter, brown sugar, cinnamon, and 1 thin sliced apple. There’s just enough topping to add some additional sweetness, but there’s not so much that it packs in a ton of unnecessary empty calories.

Wet Ingredients

To keep this baked oatmeal moist and also add some additional apple flavoring, I include ~2 cups of apple sauce in the batter. Make sure to look for unsweetened apple sauce (like this) to avoid adding additional empty calories from sugar – especially because this recipe already includes a little bit of sugar for some sweetness!

Tip: If you don’t typically consume apple sauce, try to reduce food waste by adding your leftover apple sauce into a smoothie or some overnight oats!

Other wet ingredients include eggs, melted butter, milk, sugar, and vanilla extract.

Dry Ingredients

The second most important ingredient in this recipe is the quick oats. I suggest using quick oats when making baked oatmeal because I find it creates the best texture. However, if you prefer to use rolled oats…it should still work out great!

You’ll also need: flour, cinnamon, baking powder, and a dash of salt.

Make Apple Upside Down Baked Oatmeal into a Balanced Meal

It’s appropriate to enjoy this recipe alone for a pre-workout snack or as dessert, but you could also create a balanced breakfast by pairing it with a protein source. For example: greek yogurt, boiled or scrambled eggs, or even a quick protein shake if you’re headed out the door in a pinch!

  • 1 medium apple sliced thin
  • 0.5 tsp cinnamon

Wet Ingredients

  • 16 oz unsweetened apple sauce 2 cups
  • 2 large eggs
  • 1/2 cup granulated sugar
  • 1/2 stick butter melted
  • 1 cup low-fat milk
  • 1 tsp vanilla extract

Dry Ingredients

  • 1 cup all purpose flour
  • 2 cups quick cooking oats dry
  • 2 tsp cinnamon
  • 2 tsp baking powder
  • 1 dash salt


  • Preheat oven to 350F
  • Lightly coat 9x13in baking dish with nonstick spray

Prepare the topping

  • Heat 1/2 stick butter, brown sugar, and cinnamon over low heat until combined and sugar is dissolved
  • Pour into baking dish & lightly spread into a thin layer
    *It's okay if its not spread perfectly!
  • Place the apple slices in a single layer on top
  • Transfer to fridge while preparing the oatmeal mixture

Prepare oatmeal mixture

  • In a large bowl, combine wet ingredients: apple sauce, eggs, sugar, butter, milk, and vanilla extract
  • In a medium bowl, combine dry ingredients: flour, dry oats, cinnamon, baking powder, and salt
  • Add dry ingredients to wet ingredients. Stir until combined.


  • Remove baking dish from fridge and add the oat mixture on top of the apple topping
  • Bake for ~35 minutes – or until toothpick comes out clean


  • When finished baking, carefully use a butter knife along all 4 edges of the baked oatmeal to release all sides before flipping
  • Using oven mitts, place a large cutting board on top of your baking dish. Hold the cutting board and baking dish together tightly and carefully flip – you might need to borrow an extra pair of hands for help! Return the cutting board to the table with the baking dish on top & upside down
  • Allow the dish to rest upside down on top of the cutting board for a few minutes so the topping will sink into the baked oatmeal
  • Carefully remove your baking dish and allow baked oatmeal to cool before slicing
