Baked Chocolate Oatmeal (Meal Prep Recipe)
If your mornings are rushed but you still want something warm, satisfying, and a little indulgent, this chocolate baked oatmeal checks every box. It’s rich, fudgy, and tastes like dessert for breakfast, without any complicated steps. You only need a few pantry staples and about 5 minutes of hands-on time before the oven does the rest. It’s the perfect make ahead breakfast for busy mornings, after-school snacks, or those moments when you just want something warm and chocolatey.
I make baked oatmeal all the time because it fits so well into a full schedule, quick to prep, easy to customize, and great for meal prep. And out of all the flavors I’ve made over the years, this chocolate version always disappears first. It bakes up soft and cozy, works with simple ingredients you likely already have, and holds up beautifully in the fridge all week. If you love chocolate and want a breakfast that feels a little indulgent but still practical, this is the one to make.
Once you find out how easy life is with baked oatmeal on hand, you should try this chocolate chip baked oatmeal, cinnamon roll baked oats (so much easier than a cinnamon roll but all the flavor) or this apple pie baked oatmeal that is perfect any time of the year.
Key ingredients and substitutions
A full list of the ingredients is below in the recipe card, these are just some key ingredients that I thought would be helpful to highlight.
- Maple syrup – Adds the perfect touch of sweetness. Honey or your favorite liquid sweetener works too.
- Ground flax – Acts as the “egg” in this recipe. If you’re out, chia seeds will work the same way.
- Rolled oats – Best for soft, chewy baked oatmeal. Quick oats work in a pinch; avoid steel-cut oats.
- Chocolate chips – Use chips or chunks for those melty chocolate pockets in every bite. Use dairy free if you need the recipe to be dairy free.
How to make baked chocolate oatmeal
In a bowl combine the dairy free milk, maple syrup and ground flax. Stir well so the flax doesn’t clump. Add the rolled oats, cacao powder and baking powder to the bowl. Stir well. Last add about half of the chocolate chips. Stir to incorporate. Spray a large casserole dish with avocado oil (or olive oil spray). Pour the oatmeal mixture into a casserole dish, top with the remaining chocolate chips. Bake in a 350F oven for 40 minutes. After baking, allow to cool and slice into squares.

Recipe Notes
- Texture changes as they cool: If you serve the baked oats immediately, they’ll be very soft, like stovetop oatmeal. If you let them cool completely, they will firm up and slice cleanly.
- Gluten free note: If you need this recipe to be certified gluten free, use certified gluten free oats (oats can be cross-contaminated during processing).
- Doubling the recipe: To double, bake in a 9×13 pan and add 5–10 minutes to the bake time so it cooks through.
- Fridge: Store in the fridge in an airtight container for up to 5 days.
- Freezer: Store in the freezer for up to 3 months in a freezer safe bag or container.

Other mix in ideas
If you want to change up the flavor or texture, here are the easiest mix-ins to try:
- Nuts & Seeds: chopped pecans, walnuts, almonds, pumpkin seeds, shredded coconut
- Fruit: raspberries, strawberries, cherries, or sliced banana (Tip: Add 5 extra minutes of baking time when using fresh fruit.)
- Flavor Boosters: peppermint extract (⅛ tsp), coconut extract (½ tsp + shredded coconut), or almond extract (½ tsp + chopped almonds)
- Chocolate/Coffee: cacao nibs, espresso powder, or replace part of the milk with cooled coffee
Topping ideas
These toppings pair best with chocolate baked oatmeal and take almost no extra time:
- Nut or Seed Butters: almond, peanut, cashew, tahini, or coconut butter
- Fruit: fresh berries or sliced banana
- Sweet Drizzle: maple syrup or honey
- Creamy Toppings: Make my maple cashew frosting or make your own high protein topping by combining greek yogurt with some maple syrup)
- Whipped Topping: coconut whipped cream, dairy free whipped cream or whipped cream
- Extra Chocolate: drizzle of chocolate tahini or melted chocolate
How to serve
My favorite way to enjoy this is typically covered in almond butter and sliced fruit (strawberries or banana). Sometimes though, I take a big scoop out right after baking (so it’s soft and warm) and drizzle with just a touch maple syrup for extra sweetness.
Common questions
What size baking dish do I need
An 8×8 pan works best, but this recipe is very forgiving, use the closest size you have, just note that thinner layers cook a little faster. If doubling the recipe, use a 9×13 pan.
How do I know it’s done?
The baked oatmeal should be set in the center (no jiggle) and the top should look darker than when it went in the oven. It will be soft right out of the oven but firm up as it cools.
Can I make this in advance?
Yes, that is one of the best parts about baked oats. You can store this (covered) for up to 5 days in the fridge (perfect for holiday breakfast or meal prep).
Reheating instructions:
- Microwave 30-60 seconds
- Air fryer/toaster oven: 350F for 3-4 minutes until warmed through
- Whole pan: Bake in 350F oven for 15-20 minutes, covered
Can you freeze baked oatmeal?
Yes. Allow the oats to cool completely, then cut into squares. I recommend that you place a piece of parchment paper between the squares when freezing.
Defrost individual servings in the fridge overnight or in the microwave or toaster oven.
