Chocolate Baked Oatmeal (aka Brownie Baked Oatmeal) tastes and looks like dessert…but it’s actually a fairly healthy breakfast (or lunch or dinner or snack). This recipe is a fan favorite!

Why Make Brownie Baked Oatmeal

As a mom, I’m always looking for breakfast options for my family that aren’t filled with junk ingredients and that will keep us satiated all morning. This baked oatmeal does the trick! It’s filled with nutritious, real food ingredients (keep reading) AND it tastes like dessert! Win-win!

Plus, you can double the recipe and freeze one for later, using our freezing instructions. We say this all the time, but making freezer meals is one of the best uses of your time in the kitchen.

Ingredients Needed

What is healthy about this Chocolate Oatmeal, you ask? Well, let’s take a look at the ingredients and some of the benefits.

  • Oatmeal – fiber
  • Flaxseed – fiber, healthy fat
  • Eggs – protein
  • Milk – protein, calcium
  • Avocado oil – healthy fat
  • Pumpkin – vitamin A, fiber
  • Honey – all-natural sweetener
  • Cocoa powder – antioxidants
  • Dark chocolate chips – antioxidants
  • Other ingredients – baking powder, salt, cinnamon, vanilla

How to Make Chocolate Baked Oatmeal

This recipe takes about 30 minutes from start to finish. Here’s how it goes…

Step 1: Combine the Dry Ingredients

In large mixing bowl, stir together the dry ingredients. (Note: Our pic is missing the cocoa powder. Oops!)

Step 2: Combine the Wet Ingredients

In another mixing bowl, whisk together the wet ingredients.

Step 3: Combine Wet & Dry Ingredients

Add the wet ingredients to the dry. Stir them together and then stir in the chocolate chips. (A spoon might work better than a whisk for this job. We got lazy. Hee, hee.)

Step 4: Pour into a Baking Dish

Spread the batter in a greased 9×13 inch dish.

At this point, you can freeze this dish. Cover the surface with plastic wrap and pop on the lid or wrap the dish in a few layers of foil or plastic wrap.

Step 5: Bake the Oatmeal

Bake for about 20 minutes or until the middle is just set.

Step 6: Serve Warm

We love it served warm in a bowl with fruit (like banana, strawberries, or raspberries) and milk on top. Or you can eat it almost like a soft granola bar.

What to Serve with Chocolate Oatmeal

This sweeter baked oatmeal pairs well with a high-protein savory breakfast dish like these egg recipes.

  • Baked Ham Egg Cups
  • Cheddar Chive Egg Bites
  • Oven Omelet

More Baked Oatmeal Dishes You’ll Love

If you enjoy baked oatmeal as much as our families do, give a few of these others a try. They all work well to freeze before baking, as well.

FAQs

Can you prep Baked Oatmeal ahead of time?

Yes, you can prep baked oatmeal (unbaked) ahead of time and store it in the fridge for up to 5 days or in the freezer for up to 3-6 months. Thaw and bake per instructions.
You can also fully cook and cool the baked oatmeal ahead of time and store in the fridge for up to 5 days. Just rewarm individual portions in the microwave. Our readers have told us that they freeze fully cooked, individual portions of baked oatmeal in the freezer, as well, and rewarm in the microwave.

Can you use quick oats in baked oatmeal?

While you can use quick oats in baked oatmeal, it’s best to use rolled oats because they give the dish a heartier texture. Quick oats or instant oats can result in a denser, mushier result.

Is baked oatmeal gluten-free or dairy-free?

Baked oatmeal can be made gluten-free or dairy-free with these substitutions:
Dairy-Free Option: Use dairy-free milk in the recipe.
Gluten-Free Option: Make sure your oats say “gluten-free” on the package.

Can I make this in an 8×8-inch square dish?

Yes, this recipe will also work in a smaller dish. Just cook it 10-15 minutes longer or until it’s set in the middle.

Can you use steel-cut oats in this recipe?

Yes, but you will need to bake it longer, until the middle is set. Check for doneness with a toothpick. It will likely take about 30 minutes.

  • 2 teaspoons baking powder
  • 3/4 teaspoon salt
  • 1/4 cup cocoa powder
  • 1/2 teaspoon cinnamon
  • 1/3 – 1/2 cup honey (sub: pure maple syrup) (Note: I also replace some of the honey with liquid stevia to cut back on sugar sometimes.)
  • 2 tablespoons avocado oil (sub: melted coconut oil or butter)

  • 1 cup milk (your choice)
  • 2 eggs

Instructions

Make It Now:

  1. Preheat oven to 350°F. Grease a 9×13 inch baking dish with cooking spray.
  2. In a large bowl, stir together the oats, ground flaxseed, baking powder, salt, cocoa powder, and cinnamon.
  3. In medium bowl, whisk together the honey, butter/coconut oil, pumpkin, milk, eggs, and vanilla.
  4. Pour the wet ingredients into the dry ones. Stir until combined. Then, stir in the chocolate chips.
  5. Pour batter into the baking dish. Bake for about 20 minutes (or until the edges are firm and the middle is still a little soft).
  6. Serve warm in a bowl with your favorite cut-up fruit (i.e. bananas, strawberries, raspberries) and milk on top.

Freeze For Later: 
If you want to freeze this and bake later, prepare according to directions but freeze it before baking. Wrap tightly in a few layers of plastic wrap and one of foil and freeze.

Prepare From Frozen: When ready to eat, thaw in the fridge for 24 hours and baked according to directions.


Notes/Tips

  • Gluten-Free Version: Use gluten-free oats.
  • Dairy-Free Version: Use non-dairy plain milk like almond milk or oat milk. Use dairy-free chocolate chips, like Enjoy Life brand.
  • Can I use steel cuts instead? Yes, you will need to bake it longer, until the middle is set. Check for doneness with a toothpick. It will likely take about 30 minutes.

    We’ve made this several times now and the kids are in love! I’ve put a ban on boxed cereal so I have a feeling that we’ll be making this more often! In an effort to make the morning less hectic now that I’ll be making breakfast each morning, I wan wondering if anyone has given a go to freezing this or putting it together the night before. I was already thinking to having bags of the dry ingredients prepared so all we have to do is mix in the wet. But if it can freeze and be baked from frozen, even better!

      I have made this several times and frozen it unbaked. It thaws in the fridge overnight or on the counter for a short bit. I haven’t cooked it from frozen. What a great idea to pre-make the dry ingredients, though!

    I was making this as a snack, but then scrolled down through the post and I think you have this for BREAKFAST!!! Warm milk on top! Okay we will have some now for snack and for breakfast again tomorrow. And have you tried this in ice cream? I think Todd will know how that tastes tonight 🙂

      Yep, a regular breakfast, although I don’t usually include the chocolate chips anymore and I use honey or liquid stevia sometimes in place of the sugar. Makes me a feel a little less guilty. 🙂

    Wow!!! This was delicious! I just made these with my daughters, 22 months, and 4.5 years old. They had a BLAST making them. They had SOOO much fun scooping, measuring and mixing all of the ingredients. I used Vanilla Almond Milk instead of regular milk and cut the vanilla in half.

    We enjoyed it soo much that there is only 1/4 of the 9×13 pan left. lol I’ll definitely be making this again soon, probably tomorrow. I just need to get more eggs and chocolate chips. I used mini chocolate chips and it was perfect.

    Made this for breakfast this morning! We loved it. My kids won’t eat oatmeal in it’s traditional style, so I’m looking for ways to serve it. This was a great intro to baked oatmeal for them! Maybe soon they will allow fruit in their food & we can do a baked apple recipe!

      Oh yeah, Stacey. I use applesauce or mashed bananas in this a lot. P.S. I sneak pureed pumpkin into tons of stuff, so I have a can in the cabinet always. I’m a nerd like that. 🙂

      That’s a great question! I will add a link to this post, but it’s called Oven Omelet. It’s one of the easiest breakfast (or dinner) dishes I make for my kids. You can find it here: https://thrivinghomeblog.com/2011/02/the-incredible-edible-oven-omelet/

        Thanks! It can sit on the counter for a day or two, but stays fresh longer if you store in the fridge. Hope that helps!
