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.

  • 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 and 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.

  6. Serve warm in a bowl with your favorite cut-up fruit (i.e. bananas, strawberries, raspberries) and milk on top.

Freezer Instructions

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 cut oats 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.
