S’mores Baked Oatmeal – Eating Bird Food

Have dessert for breakfast with this s’mores baked oatmeal! It’s made with healthy ingredients and studded with mini marshmallows, graham crackers and chocolate chips.

Back with another new baked oatmeal variation and this one is an ode to my childhood… s’mores baked oatmeal!

Some of my favorite childhood memories are gathering around the campfire with my family to roast marshmallows for s’mores. I can’t wait to continue the tradition with Tucker and Olivia.

This baked oatmeal is definitely one of the more decadent ones on EBF because of the marshmallows and graham crackers, but it’s still delicious and can be served for breakfast or dessert!

Why You’ll Love This Recipe

• It tastes just like the s’mores we all know and love but in oatmeal form!
• Easy to make in just one bowl! Yay for less dishes.
• Great for meal prep! Make a batch during your weekend meal prep and have breakfast or dessert ready to go for the week.
• Kid-approved! This is a great recipe to get your kiddos involved in. They’ll love topping the baked oatmeal with the mini marshmallows, chocolate chips and graham crackers.

Ingredients Needed

• old fashioned rolled oats – my fave brand is Bob’s Red Mill gluten-free old-fashioned rolled oats. Oats are naturally gluten-free but often cross-contaminated with gluten, so if you have a gluten intolerance, grab certified gluten-free oats.
• unsweetened almond milk – I like using unsweetened almond milk, but any non-dairy milk will work. You can make your own following my homemade almond milk recipe.
• maple syrup – pure maple syrup is the perfect natural sweetener to use for baked oatmeal in my opinion! Just be sure to use pure maple syrup, not the artificial kind labeled “pancake syrup” and made from corn syrup… NOT the same!
• applesauce – adds moisture and natural sweetness to this baked oatmeal.
• ground flaxseed – instead of an egg we’re using flaxseed to help bind the dish together. You can also use chia seeds if that’s what you have on hand. If you don’t need this recipe to be vegan, you can swap the flaxseed for 1 regular egg.
• coconut oil – to add moisture to the baked oatmeal. I’ve purchased several different brands of coconut oil before, but Nutiva organic extra virgin coconut oil is my favorite.
• vanilla extract – a flavor enhancer.
• baking powder – helps the baked oatmeal rise.
• sea salt – brings all the flavors together.
• chocolate chips – I like using Lily’s dark chocolate chips – they have no sugar added and are dairy-free.
• mini marshmallows – can’t have s’mores without the marshmallows. Any brand of mini marshmallows work. Make sure to grab vegan marshmallows if needed. I like the Dandies vegan mini marshmallows.
• graham crackers – another key element of s’mores! Any brand of graham crackers work. Grab gluten-free if needed. I like Annie’s organic honey graham crackers.

How to Make

Preheat the oven to 375°F and spray an 8×8 square baking dish with cooking spray. Combine oats, milk, maple syrup, baking powder, sea salt, flaxseed, coconut oil, applesauce, vanilla, ¼ cup chocolate chips and ¼ cup marshmallows in a large mixing bowl. Stir to combine using a spatula.

Carefully pour batter into the prepared baking dish. Sprinkle with remaining chocolate chips, marshmallows and graham crackers.

Bake for 40-45 minutes, until toothpick comes out clean. Let cool for 10-15 minutes then portion into 6 pieces and serve warm.

Substitutions & Notes

• Rolled oats: rolled oats work best for baked oatmeal and I don’t recommend swapping them for quick oats or steel-cut oats as the liquid ratio and cook time will differ. If you’re looking for a baked oatmeal recipe that’s made with steel-cut oats I suggest checking out this baked steel cut oatmeal recipe instead.
• Milk: any milk you like, such as cow’s milk, soy milk, oat milk, coconut milk, almond milk, or coconut milk.
• Applesauce: if you don’t have applesauce on hand mashed, ripe bananas will work well!
• Maple syrup: any liquid sweetener like honey, agave or monk fruit maple syrup will work instead of maple syrup.
• Coconut oil: butter, ghee or any neutral oil like avocado oil or olive oil will work as a substitute. I’ve also made baked oatmeal without coconut oil and it turned out just fine!

How to Add Protein to This Baked Oatmeal

I know this baked oatmeal is a bit more decadent, so adding more protein could be a good way to balance out the recipe and make it more filling, especially if you’re enjoying it for breakfast. Here are some ideas:

• Add protein powder: You could add 1-2 scoops of protein powder to the mixture, you might just need to add a bit more liquid, depending on how much protein powder you add. You can follow my protein baked oatmeal recipe as a guide.
• Use egg whites: Swap the flaxseed meal with egg whites for a touch of protein.
• Toppings: When serving, top your baked oatmeal with peanut butter, almond butter, or another nut butter of choice. You could also top it with Greek yogurt for an added protein boost.

How to Make Blended Baked Oats

To turn this recipe into blended baked oats, blend all the ingredients together in a high-speed blender or food processor, except for the mix-in’s/toppings. Fold in the chocolate chips and marshmallows, pour into your prepared baking dish, sprinkle with remaining toppings and bake as directed! This will result in more of a cake-like recipe. Perfect for a summer dessert!

Storing & Reheating

This s’mores baked oatmeal is perfect for meal prep because it stores beautifully. Here’s how you can store and reheat leftovers:

• Refrigerate: allow the baked oatmeal to cool, then cover the baking dish or transfer individual portions to an airtight container. It’ll stay fresh in the fridge for up to 5 days.
• Freeze: you can also freeze baked oatmeal for up to 3 months. To do this, let the oatmeal cool completely, then cut into portions and store in freezer-safe containers or bags.
• To reheat the entire pan of baked oatmeal: cover with foil and reheat in the oven at 350ºF for about 20 minutes or until warm.
• To reheat individual portions: set oven or toaster oven to 350ºF and bake for 5-10 minutes. You can also reheat in the microwave for 1 minute. Once warm, add your toppings and enjoy!
