Wen breakfast tastes like dessert >>>. This baked apple cinnamon oatmeal is gluten free, dairy free, refined sugar free, and extremely DELISH.

I’ve been working away at creating a bunch of Thanksgiving/holiday recipes for you guys. I wanted to throw a breakfast recipe in there too! That’s honestly one of my favorite part about the holidays– waking up at my parents house and eating a cozy special breakfast made by my mom with the family. It’s the best!! I think I will finally contribute to the family breakfast this year with this one 😉

This baked oatmeal a recipe that makes for a great meal prep breakfast, or for a holiday morning breakfast with the family.

There’s a few simple steps before popping this goodness in the oven. A quick sauté of the sliced apples and chopped nuts- a step that’s totally worth it for soft, dessert-like apples. Plus the most amazing smells in your kitchen!

Can I prep any of this oatmeal bake ahead of time?

Yes! You can make the maple cashew cream cheese frosting the day before.

You could also get the dry ingredients mixed together (oats, baking powder, cinnamon, and salt) the night before if you wanted to! That way, you’ll just have to sauté the apples/nuts and get the wet ingredients whisked together in the morning.

Side note: I made this for a meal prepped breakfast and it was still just as delicious on day 4!

Cozy and simple baked maple apple cinnamon oatmeal! The perfect healthy, yet sweet, breakfast! 



For the apples:

  • 1 apple, sliced into 1/4″ thick slices, then sliced in half again width-wise (option to peel the apple)
  • 1/3 cup chopped pecans or walnuts
  • 1 tbsp butter (sub coconut oil for dairy free)
  • 1 tsp cinnamon
  • 1 tsp maple syrup

For the oatmeal bake:

  • 1.5 cups oats 
  • 1 tsp baking powder 
  • 1/2 tsp sea salt 
  • 1 tsp cinnamon 
  • 1/3 cup unsweetened apple sauce 
  • 1/4 cup almond or sunflower butter 
  • 1 tsp vanilla 
  • 1/4 cup maple syrup 
  • 1 large egg 
  • 3/4 cup unsweetened dairy free milk of choice

For the maple cream frosting:

  • 3/4 cup raw cashews (*see note)
  • 5 tbsp filtered water
  • 3 tbsp maple syrup
  • 1 tsp vanilla extract
  • 1/4 tsp apple cider vinegar 
  • dash of sea salt



  1. Preheat oven to 350°F and grease an 8×8 baking dish with butte or coconut oil.
  2. To prepare the apples and nuts, heat a skillet over medium-low heat and add the butter. Once melted, stir in the apples, nuts, and cinnamon. Sauté for 3 minutes, then stir in maple syrup and sauté for 1 more minute. Remove from heat and set aside to cool.
  3. In a large bowl, mix together oats, baking powder, sea salt, and cinnamon.
  4. In a separate bowl, whisk together apple sauce, almond butter, vanilla, maple syrup, egg, and almond milk until very smooth. Stir in with dry ingredients until everything is well combined. 
  5. Stir in the apple/nut mixture, then spread batter out into the prepared 8×8 baking dish. Bake for 25 minutes.
  6. While oatmeal is baking, prepare the maple cashew cream cheese frosting. Add the drained and rinsed cashews with all other ingredients in a high speed blender and blend until a very smooth frosting forms.
  7. Allow oatmeal bake to cool slightly before frosting and serving (I like to frost with about half of the frosting, then save the other half for serving). Store leftovers in an airtight container in the refrigerator for up to 5 days.


*Cashews do not need to be soaked as long as you have a high speed blender. If your blender is not high speed, I recommend soaking the cashews for at least 4 hours, or overnight.

    FANTASTIC! Apples and cinnamon are one of my favorite combinations and this recipe combines them so well. I love baked oatmeal, but I can rarely make it since most recipes involve bananas and I hate bananas. I made this one this morning for breakfast and honestly debated eating it for lunch and dinner too!!!

  2. Amber says:

    Okay, I’ve never made any frosting out of cashews but WOW! What a game-changer!! It’s like a cinnamon roll oatmeal bake. It is AMAZING!

    For the applesauce, do you know a substitute I could use? Thank you

    Does it require refrigeration even if it’s not frosted? I made it tonight and want to serve it for breakfast tomorrow morning! Btw the whole house smells heavenly!
