How to Make S’mores Baked Oatmeal Recipe

Step 1: Prep Your Ingredients and Baking Dish

Start by preheating your oven to 375°F—this ensures it’s perfectly hot when your oatmeal goes in. While it’s heating, spray an 8×8 square baking dish with cooking spray to prevent sticking, making cleanup a breeze later.

Step 2: Mix the Oatmeal Base

In a large mixing bowl, combine the oats, almond milk, maple syrup, baking powder, sea salt, ground flaxseed, melted coconut oil, applesauce, vanilla, and half of your chocolate chips and mini marshmallows. Stir everything together until it’s well incorporated and the oats get nicely coated with the liquid goodness.

Step 3: Transfer to the Baking Dish

Pour the oatmeal mixture carefully into your prepared baking dish, spreading it evenly. This even layer ensures consistent baking and those delightful pockets of chocolate and marshmallow throughout.

Step 4: Add the Toppings

Sprinkle the top with the crushed graham crackers along with the remaining chocolate chips and mini marshmallows. These toppings are what give the dish its unmistakable s’mores charm—a crunchy, melty finish that’s absolutely irresistible.

Step 5: Bake to Perfection

Slide your baking dish into the oven and bake for 40 to 45 minutes. You’ll want to bake until a toothpick inserted in the center comes out clean and the marshmallows on top are golden and bubbly. This slow bake lets all those flavors meld together beautifully while developing a comforting crust.

Step 6: Cool and Serve

Allow the baked oatmeal to cool for 10 to 15 minutes before cutting into six generous servings. Enjoy it warm to experience the full ooey-gooey s’mores effect!

Make Ahead and Storage

Storing Leftovers

Any leftover S’mores Baked Oatmeal Recipe can be stored in an airtight container in the refrigerator for up to 4 days. Keeping it chilled helps maintain its texture and allows the flavors to develop even more.

Freezing

Freezing is a great option if you want to enjoy this treat later. Cut the baked oatmeal into individual portions, wrap them tightly in plastic wrap, and place them in a freezer-safe bag or container. It will keep well for up to 2 months.

Reheating

To reheat, simply microwave a portion for about 60 seconds until warm and melty again. You can also heat it in the oven at 350°F for 10 to 15 minutes if you prefer a crispier top layer. Either way, you’ll bring back that fresh-out-of-the-oven magic in minutes.

FAQs

Can I use dairy milk instead of almond milk?

Absolutely! Dairy milk works just as well in this S’mores Baked Oatmeal Recipe and will give you a slightly creamier texture. Feel free to use whatever milk suits your preference.

What if I don’t have ground flaxseed?

If you don’t have ground flaxseed on hand, you can omit it or substitute with chia seeds. It helps add moisture and a bit of nutritional boost, but the recipe will still taste great without it.

Can I make this gluten-free?

Yes! Just be sure to use certified gluten-free oats and graham crackers to keep the recipe safe for gluten-sensitive folks. The rest of the ingredients are naturally gluten-free.

How sweet is this baked oatmeal?

This recipe balances natural sweetness from the maple syrup and applesauce with the melty chocolate and marshmallows on top, so it’s sweet without being sugary. If you prefer it sweeter, feel free to add a touch more maple syrup.

Can I add nuts or other toppings?

Definitely! Chopped nuts like pecans or walnuts can add a wonderful crunch. You can also mix in dried fruit or shredded coconut to customize your S’mores Baked Oatmeal Recipe to your liking.
