Ingredients You’ll Need

I love how these ingredients come together to create such a creamy, flavorful baked oatmeal. The flaxseed acts as a perfect egg substitute, while the applesauce adds a natural sweetness and moisture without overpowering the peanut butter star.

• Ground flax seeds: This is our egg substitute here, so let it soak in water for a few minutes to get that perfect gel-like consistency.
• Gluten free rolled oats: I always reach for rolled oats instead of instant—they hold their shape better in baking and give a nice chewy texture.
• Baking powder: Just a little to help give the oats a light fluffiness.
• Cinnamon: It pairs amazingly with peanut butter and adds that cozy warmth you want in a baked oatmeal.
• Non-dairy milk: Any plant milk works, from almond to oat to soy—whatever you have on hand will do.
• Applesauce: Keeps the dish moist and naturally sweet without extra processed sugar.
• Peanut butter: Creamy and rich, this is the star that makes every bite heavenly—chunky works too if you like texture!
• Vanilla extract: Just a splash to elevate all the flavors.
• Maple syrup: Adjust this depending on your sweetness preference.
• Salt: Just a pinch balances the sweetness perfectly.
• Chia jam: You can also swap for any jam or fruit preserves you love.

Variations

One of the things I love most about this Vegan Baked Peanut Butter Oatmeal Recipe is how easy it is to make your own. Whether you want to sneak in some extra fruit or experiment with different nut butters, there’s room to play.

• Berry Nut Twist: I often swirl in fresh or frozen berries before baking for that extra burst of fruity goodness—my family goes crazy for this combo.
• Almond Butter Swap: Tried swapping the peanut butter for almond butter once, and it gave a subtly different nuttiness that was equally delicious.
• Spiced Up: Adding a pinch of nutmeg or ginger can amp up the warm spice profile if you like a little zing.
• Chunky Texture: Tossing in chopped nuts or vegan chocolate chips before baking adds texture and fun surprises in every bite.

How to Make Vegan Baked Peanut Butter Oatmeal Recipe

Step 1: Prep Your Flax “Egg”

Start by mixing the ground flax seeds with water and letting it sit for about 5 minutes. This thickens into a gel that works as the perfect vegan binder. If you’re short on time, just mix this first and get everything else ready while it firms up.

Step 2: Mix the Dry Ingredients

In a large bowl, whisk together the rolled oats, salt, cinnamon, and baking powder. I like to make sure these are well combined before adding the wet ingredients — it helps distribute the flavors evenly throughout every bite.

Step 3: Combine Wet Ingredients

Add your non-dairy milk, applesauce, peanut butter, vanilla extract, maple syrup, and the thickened flax egg into the bowl with the oats. Stir everything together until it looks beautifully blended — you’ll notice the peanut butter softening the mixture and bringing it all together.

Step 4: Bake It Up

Pour your oatmeal mix into a greased or lined 9×9 baking dish. Now comes the fun part — dollop your chosen chia jam right on top! You can swirl it in gently if you want, or spread it in dollops and get those sweet pockets of jam as you bake. I usually add a little extra peanut butter on top before baking and then again after — it melts into a dreamy peanut buttery layer.

Bake at 350°F (175°C) for about 25-30 minutes or until a toothpick inserted in the center comes out clean. After baking, let it cool for about 10 minutes — this helps it set up nicely and makes it easier to serve.

How to Serve Vegan Baked Peanut Butter Oatmeal Recipe

Garnishes

I usually top mine with a swirl of extra peanut butter and a generous spoonful of fresh chia jam to make each bite a little extra special. Fresh berries or sliced bananas are another favorite of mine—they add a touch of brightness and texture that balances the richness perfectly.

Side Dishes

If you’re serving this for brunch, I like pairing it with a side of fresh fruit salad or a handful of roasted nuts. Sometimes a hot cup of chai tea or coffee rounds out the cozy vibe perfectly!

Creative Ways to Present

For a special occasion, I’ve served this baked oatmeal in individual ramekins topped with a drizzle of peanut butter and a sprig of fresh mint for a pretty, restaurant-style look. Layered in jars with alternating oatmeal and jam makes a fun grab-and-go breakfast that guests love.

Make Ahead and Storage

Storing Leftovers

I store leftover baked oatmeal covered tightly in the fridge for up to 4 days. It holds its texture surprisingly well, and I usually just pop a piece in the microwave for a minute or so when I’m ready to eat.

Freezing

This recipe freezes beautifully! I slice it into portions, wrap them individually in plastic wrap or freezer-safe containers, and freeze for up to 2 months. It’s a game changer for busy mornings when you want homemade but have zero prep time.

Reheating

I like reheating frozen or refrigerated slices in the microwave just until warmed through. Adding a splash of plant milk before heating helps revive its creamy texture so it doesn’t dry out or get rubbery.
