Gluten Free Apple Cinnamon Baked Oatmeal - a nutritious breakfast recipe

How to Make Apple Cinnamon Baked Oatmeal

Begin by preheating the oven and lightly spray a large casserole dish with cooking oil.

Add all of the dry ingredients to a mixing bowl and stir together.

Similarly, add all of the wet ingredients to a separate mixing bowl and whisk until combined. Pour the wet ingredients into the bowl with the dry ingredients and stir well.

Transfer the oatmeal mixture to the prepared casserole dish, and bake!

While the apple cinnamon baked oatmeal is in the oven, you can prepare the coconut milk drizzle. Simply combine coconut milk and sugar in a saucepan and reduce it down.

Tick, tick, tick, tick, boom dynamite! Although the breakfast bake is scrumptious by itself, the coconut sauce that you drizzle on top sets the whole thing a-flame.

You can save the leftovers and eat on this breakfast for days! I definitely recommend you bookmark this recipe for when you have company so that you can keep the recipe on-hand for brunch with family or friends!

Gluten Free Apple Cinnamon Baked Oatmeal

Recipe Adaptations:

  • Replace the butter with vegan “butter” spread or avocado oil to make recipe dairy-free.
  • Use cane sugar instead of coconut sugar 
  • Add chopped walnuts, pecans, and/or raisins
  • The oatmeal itself is not super sweet. For sweeter oatmeal, add more coconut sugar and/or an additional 1/4 cup of pure maple syrup.

Apple Cinnamon Baked Oatmeal:

For coconut milk glaze:


Prepare the Apple Cinnamon Baked Oatmeal

  • Preheat the oven to 350 degrees.
  • Prepare a lightly oiled (or parchment-lined) 9 x 13 casserole or baking dish
  • In a large mixing bowl, combine the dry ingredients (oats, shredded coconut, chopped apple, coconut sugar, cinnamon, salt, and baking powder). Mix well to combine.
  • In a separate mixing bowl, whisk together the eggs, almond milk, melted butter, lemon juice and vanilla extract.
  • Pour the wet mixture over the dry oat mixture and stir to combine.
  • Transfer the oatmeal mixture into the prepared baking dish. Spread the mixture around so that the apples aren’t poking up too far and the mixture is evenly distributed.
  • Bake in the oven for 40 to 50 minutes or until the top is golden brown and all of the liquid appears to be absorbed.
  • Allow the baked oatmeal to cool 15 minutes before slicing large portions and serving with coconut milk glaze on top (instructions below)!

Prepare the Coconut Milk Glaze:

  • Add coconut milk and sugar to a small saucepan and bring it to a gentle boil.
  • Reduce heat to medium and allow the coconut mixture to continue cooking, whisking frequently, until the coconut milk begins to thicken and turns a slightly darker shade. This process should take about 20 to 25 minutes.
  • Remove coconut milk glaze from the heat and allow it to cool slightly. The longer it cools, the thicker the mixture will become.
  • Drizzle the glaze over the baked oatmeal and enjoy!


*If you'd like, use a combination of oats and muesli. 2 cups of oats and 2 cups of muesli is a good ratio 🙂
**You can substitute the butter for non-dairy "butter" spread if you don't do dairy or use avocado oil instead.
***If you'd like, you can make a standard glaze using 2 cups of powdered sugar and 2 to 4 tablespoons of water or milk

Questions and Reviews

  1. I’ve never had Bob’s Muesli, seen it in stores but never picked it up. If its like any of their other products its probably pretty darn good. Wow, your breakfast bake looks fantastic! I am a huge fan of the cinnamon roll but as we all know they aren’t the healthiest, these look like a good substitute.

  2. Would LOVE to win the muesli! Also looking forward to trying this recipe for the Muesli breakfast bake! Yum!!!

  3. You’re a genius! I love that this is dairy free and low sugar as well…. cannot WAIT to try it! Now if only there was a recipe for your cooking magic…..


  4. YUM!! My boyfriend is obsessed with muesli, so I’m sure he’ll love it when I make this for him 🙂

  5. Yes, yes, yes! I want this right now for breakfast. I’m obviously not in the loop (and no comment from a certain daughter of mine), because I don’t know what a ZipList recipe box is. I must investigate this. Meanwhile, I guess I’ll just go eat my bowl of cereal today and feel sorry for myself.

  6. P.S. Don’t forget to remind me to vote for your recipe tomorrow. Can we vote more than once, or is it a one-time deal only?

  7. I follow BRM on Pinterest. I also dislike the multiplication ones. I think you should get some language things.

  8. lady, this sounds fantastic! Can I come over for breakfast? Save a little extra coconut cream sauce for me as well 🙂

  9. This recipe sounds AMAZING!! Must try… wish I had a nice piece to enjoy with my coffee right now. 🙂

  10. Can’t wait to try this muesli recipe! I’m looking to add some variation to my breakfasts.

  11. I’m about to crown you the breakfast queen! I’ve got a lot of breakfast requests when I show up at your doorstep one of these days. 😉

  12. I’m not much of a muesli fan for breakfast. But your breakfast bake has me reconsidering my desires! What a scrumptious way to begin the day!

  13. I’m new here! Love the blog and love Muesli! Great idea for a breakfast cake- this is getting pinned for my breakfast recipes to take to playgroup board…

  14. This breakfast bake looks SO mouthwatering, Julia! Thanks for sharing your recipe and this delish giveaway!

  15. Looks yummy! I like to make whipped cream with coconut milk and eat it over strawberries. Yum!

  16. Gluten free rolled oats??? Sounds complicated… My Husband has recently been diagnosed with a gluten allergy and also a wheat allergy…both serious so I’ve been reading as much as I can on gluten free and wheat free cooking. The GF muesil breakfast bake sounds delicious…I will look for the ingredients at the market and make this for a weekend dish.

    1. Hi Libby, you hit the nail on the head – GF oats are not easy to produce but thankfully, Bob’s Red Mill makes both the GF Muesli and GF rolled oats, so check out your natural food section and I bet both items are there. It’s pretty amazing how delicious gluten-free cooking and baking can be, so remember you can always use Bob’s as a resource for ingredients. Thanks for your interest and let me know how the breakfast bake turns out! 🙂

  17. Yum! I absolutely love Bob’s Red Mill. They unsweetened coconut flakes are my favorite!
