Looking for a yummy, healthy, and hearty make-ahead gluten-free breakfast? These gluten-free apple cinnamon baked oatmeal squares can be made one day and enjoyed for breakfast the next few days! They’re soft and chewy, and full of chunky apples and cinnamon!

Gluten-free Apple Cinnamon Baked Oatmeal Squares - Great make-ahead breakfast idea. Can grab and go or eat in a bowl with milk or non-dairy milk. These are dairy-free too!

How do you like your baked oatmeal? Sometimes I like it plain and sometimes I like it warmed up and eaten in a bowl with non-dairy milk. I have one kid that likes to grab these and go, while the other likes to mash one up in a bowl of milk. No matter how you like to have baked oatmeal, I think you’ll like this new recipe for gluten-free apple cinnamon baked oatmeal squares.

A couple of years ago, I created these gluten-free maple brown sugar baked oatmeal squares that were a hit with my family. Some of you have tried them too and they were a hit with your family too.

I had made that recipe inspired by my boys’ favorite instant oatmeal flavor. Their other favorite instant oatmeal flavor: apple cinnamon, thus the inspiration for today’s recipe! I think these will remind you of those apple cinnamon instant oatmeal packets a bit, but in a square that you can either have in a bowl with milk or grab and go! Some days just call for portable breakfast bars!

These are also flourless! Yep – the whole grain gluten-free oats are just what you need for these, no flour, no gums.

Oats, real apple chunks and cinnamon are just delicious together!

Notes on ingredients for these gluten-free apple cinnamon baked oatmeal squares:

  • Milk: I’ve made these with regular milk and I’ve also made them dairy-free by using a nut milk or FlaxMilk. Use the option that best suits your specific allergens or dietary needs.
  • To continue the dairy-free theme with this recipe, I used melted coconut oil. I think any oil would work fine in this, if you need to avoid coconut.
  • Oats: As always, be sure to use certified gluten-free oats in this recipe. I use GF Harvest Old Fashioned Rolled Oats which I buy from Amazon here. I highly recommend these safe oats!
  • Use pure maple syrup, not the cheap pancake syrup. I buy jugs of pure maple syrup at Costco.
  • Apple: I like to choose a tart, flavorful apple for these like McIntosh, Braeburn, or Pink Lady. Use your favorite apple!
  • Cinnamon: I love this cinnamon.

The batter for this will be very loose/liquidy when you are done mixing together. THat’s how it should be! But you’ll evenly scoop into the sections of your bar pan and they’ll bake up nice! These are softer than my maple brown sugar version – these don’t get crispy like those do. These stay nice a moist due to the real apple chunks!

I make these in this brownie/bar pan and recommend getting one if you want to make grab and go breakfasts and snacks!

What else will you make with your apples and cinnamon? You’ve got to try these gluten-free apple muffins as they’re so good! And be sure to try my gluten-free apple puff pancake! Want some dessert? Let me suggest my gluten-free apple pear tart for a show-stopping dessert! Want to try a paleo dessert spin? Try this paleo apple crisp!

Ingredients

  • 3 cups gluten-free rolled oats
  • 1/3 cup brown sugar

Instructions

  1. Preheat oven to 350°. Spray each square of a brownie/bar pan with cooking spray.
  2. In the bowl of your stand mixer (or a large bowl if you prefer to mix by hand), add the oats, brown sugar, cinnamon, baking powder, and salt. Mix on low speed for 30 seconds.

  8. Store at room temperature in sealed container, or wrap individually in plastic wrap or foil for sending to school.

I love these! I made the recipe in an 8 x 8 pan, and just let it cook an extra 5 minutes. I left out the brown sugar because I’m not eating sugar at the moment, and didn’t miss it.

I have made many versions of baked oatmeal and never found one that was a favorite. I saw this recipe, ordered the recommended brownie pan and this recipe is now my favorite breakfast. The oatmeal squares are delicious, easy to make and easy to take on the go. Regular baked oatmeal always crumbled. I did not have coconut oil so I subbed an equal amount of melted butter and it came out perfect. Will try again with the oil. Thank you

Could honey be used instead of maple syrup? That’s the only ingredient I’m missing and I don’t want to run to the store!

I think that swap would work fine in these. Do come back and let me know if you try it!

What is the nutrition value for this recipe, when using molasses instead of maple syrup & Stevia instead of brown sugar?
