Baked Oatmeal

Hi, we are The Oatmeal Family.

Recently, our tribe fist-bumped each other for successfully completing our second annual 30-day sugar fast — woo hoo!  Right after that, the first thing we inhaled was oatmeal. Like, whoppers and heaps of yummy oatmeal.

Friends, it wasn’t just any old oatmeal we enthusiastically feasted on. It was this glorious Maple Cinnamon Baked Oatmeal recipe that happens to be gluten-free and refined-sugar free. We weren’t even trying for a gluten-free, sugar-free baked oatmeal recipe, but it’s just how this oatmeal bake naturally rolls. [See what I did there? 😉]

Bonus: it tastes jaw-dropping delicious.

Bake Oatmeal the night before

Literally toss together the simple ingredients, bake it, and let it cool at room temperature overnight while you get your zzzz’s and press the snooze button as many times as you like.

I mentioned the goodness that goes into our Maple Cinnamon Baked Oatmeal — sweetened with only raw, unfiltered honey and fortified your favorite kind of milk.

All that’s left for you to do is gather ’round with your people, slice into that massively delicious Maple Cinnamon Baked Oatmeal, and dig in.

A drizzle of pure maple syrup is [kind of] optional but [always] recommended.

Happy brunching.

  • Preheat oven to 375F with rack on middle position. Grease inside of an 8×8 baking pan and set aside.
  • In a bowl, whisk together the oats, cinnamon, ginger, nutmeg, baking powder, and salt until well combined.
  • In a separate bowl, whisk together the milk, honey/maple syrup, egg, applesauce, and vanilla extract until well combined. Gently stir the oat mixture with the milk mixture until incorporated. Pour into greased baking pan.
  • Bake about 38 minutes or until top is golden and toothpick inserted in center comes out mostly clean. Let cool at room temp for at least 10 minutes (or overnight, loosely covered) before serving. Top as desired and serve warm or at room temp.


If you bake this up the night before, cover and let cool at room temp overnight. Reheat in oven or toaster oven the next morning.
This recipe as written results in a tender, deliciously moist baked oatmeal that cuts easily into squares. If you prefer a drier, crispier, crumbly texture, use 1/4 cup less milk and bake a little longer.

    When I had four children under my roof to feed I used to make something similar; it’s an awesome an economical meal (not to mention this version is healthier than the one I used to make.

    • JaaCee

    You mention that it is sweetened with raw honey but I do not see it in the ingredients list. How much should/could I use?

    We are probiotic obsessed around here. But I’ve never heard of probiotic milk before. I’ll pick some up, I use milk mostly for baking.
