Our original Chocolate Chip Baked Oatmeal recipe was such a hit, we wanted to create another equally delicious version for you! This s’mores version is inspired by our Summer Skillet S’mores and our Vegan No-Bake Chewy S’mores Granola Bars. Despite being sprinkled with chocolate and marshmallows, the base oatmeal recipe is full of good-for-you ingredients and is something you can feel good about indulging in every once in a while.

Are S’mores Vegan?

If you grew up loving s’mores around the campfire around the summer, we’re sorry to say they likely weren’t vegan-friendly! Most graham crackers are sweetened with honey, chocolate bars are traditionally made creamy with dairy milk, and marshmallows almost always contain gelatin. 

The good news however is there are several vegan swaps available to make equally delicious vegan s’mores. Read on to see our brand recommendations for vegan-friendly s’mores ingredients as well as some resources to make your own vegan s’mores ingredients from scratch!

Ingredients You’ll Need

  • Oats: For baked oats, you’ll need rolled oats or oat flour. Save the steel-cut oats for making a bowl of oatmeal. 
  • Non-dairy milk: Unsweetened soy, oat, almond or cashew milk would all be great options. Note that using flavored milks will change the flavor of the oats.
  • Banana: Opt for a ripe, spotty banana over a yellow banana. The riper it is, the more natural sweetness it will add to your baked oats. 
  • Nut butter: For the best neutral nutty flavor, we’d recommend mild-flavored nut butters such as almond butter, cashew butter, or seed butters like sunbutter. Peanut butter will also work but be stronger in flavor.
  • Maple syrup: Our liquid sweetener of choice is maple syrup, but any liquid sweetener will do. Use what you have.
  • Flaxseed: Ground flaxseeds act as an egg replacer in these baked oats and help give it structure and make it easy to slice into individual servings. If you’re out of ground flaxmeal, try ground chia seeds. 
  • Vanilla: Optional, but adds depth of flavor and notes of sweetness. 
  • Baking soda + Baking powder: These leavening agents work to rise the baked oatmeal, making it light and fluffy, almost like cake! Please make sure to use both. They cannot be substituted for one another.
  • Chocolate chips: To find vegan-friendly chocolate chips, look for dark chocolate chips. They are often dairy-free and accidentally vegan. We love the brand EnjoyLife. They are certified vegan and allergen friendly and come in both regular and mini sizes. As a last resort, make your own vegan chocolate bars at home and chop them up! You could even chop up our Vegan Crunch Bars for a twist.
  • Vegan marshmallows: Dandies is the most widely available brand of vegan marshmallows. If you can’t find them in your local grocery store, they’re available on Amazon. If you live in the United States, Trader Joe’s also sells vegan-friendly marshmallows. As a last resort, make your own homemade vegan marshmallows.
  • Graham crackers: If you are looking for graham crackers without honey, we typically like using the brands Kinninkinick graham crackers (we have found them locally at natural grocers, New Seasons and Whole Foods) or Nabisco Original Grahams (the red box!). Or, try making homemade vegan graham crackers.

Equipment Needed

  • Small baking dish (ours was 7 x 9.5-inches)
  • High-speed blender
  • Spatula

How to Make Vegan S’mores Baked Oatmeal

  1. Blend the oats. In a high-speed blender, blend the oats into a fine oat flour.
  2. Add remaining batter ingredients. Once the oats are blended into a flour, add in the non-dairy milk, banana, nut butter, maple syrup, flaxseed meal, vanilla, baking powder, baking soda and salt. 
  3. Add chocolate chips and half the mini marshmallows. Using a spatula or spoon, fold them into the baked oats batter until well incorporated. 
  4. Transfer to a baking dish. Spread out evenly and sprinkle with remaining chocolate chips, marshmallows, and graham crackers. 
  5. Bake. Bake for 25 to 30 minutes, or until a toothpick inserted into the center of the baked oats comes out clean. 
  6. Serve. Allow the baked oatmeal to cool for about 5 minutes to set, then serve immediately! 

Serving Suggestions 

This baked oatmeal is sweet enough to serve on it’s own for breakfast, but if you’d like, you can’t go wrong with a small drizzle of maple syrup and a side of fresh fruit. It can also be served alongside some of our other breakfast staples, such as Vegan Breakfast Potato Hash, Crispy Vegan Bacon, or Tofu Scramble

Storage Instructions

Baked oatmeal will keep in the refrigerator for up to 4 days when stored in an airtight container. You can also freeze this S’mores Baked Oatmeal for up to 2 months, but the graham crackers will get significantly softer in the freezer. 

Leftovers can be reheated in the microwave or toaster oven until warmed through again. We recommend sprinkling additional fresh graham crackers over the top for freshness.

Recipe FAQs

Can baked oatmeal be made the night before?

Absolutely! Although the graham crackers added on top of the baked oatmeal will soften overnight in the refrigerator, and when reheated, these baked oats are still delicious the next day. Feel free to make this baked oatmeal recipe on Sunday night and enjoy it as a quick and effortless breakfast throughout the week.

How do you know when baked oatmeal is done?

Similar to baking a cake, this blended baked oatmeal will be done when a toothpick inserted into the center of the oats comes out clean. 

Does baked oatmeal have to be refrigerated?

We would recommend it. Although this baked oatmeal is similar in ingredients to our Vegan Oatmeal Raisin Cookies, they do contain a significant amount more moisture and will store best in the refrigerator.
