What is vegan baked oatmeal?

I love starting my day with a warm, hearty, and ultra-satisfying breakfast like vegan baked oatmeal. Unlike traditional stovetop or microwavable methods, the oats are baked, which results in a cake-like texture that makes you feel like you’re eating dessert for breakfast!

While you may feel like you’re eating dessert, this recipe is made with good-for-you ingredients like rolled oats, maple syrup, plant milk, and flaxseed. The result is a sweet and savory dish with a soft, cake-like texture that's incredibly satisfying.

You can enjoy this comforting breakfast straight from the oven with your favorite toppings. Some of my go-to options are fresh fruit, nuts, seeds, nut butter, and vegan yogurt!

Ingredients & Substitutions

Vegan baked oat ingredients laid out individually with labels.

Rolled oats: I suggest using old-fashioned rolled oats for a hearty and perfectly chewy-tender texture. You can substitute quick oats for a softer result.
Plant milk: I used cashew milk, but almond, oat, or soy milk all work as well.
Maple syrup: Acts as a natural sweetener and also provides beneficial minerals. If you don’t have 100% pure maple syrup, replace it with agave nectar or date syrup.
Coconut oil: Adds richness and creates a tender vegan baked oatmeal texture. Coconut oil can be replaced with vegan butter.
Vanilla extract: Enhances the sweet flavor of this recipe. Make sure you use pure vanilla extract for the best results.
Cinnamon powder: Adds warmth and extra sweetness. Feel free to use other spices like nutmeg, cloves, cardamom, and pumpkin spice.
Baking powder: Helps the oats rise, giving them a light and fluffy texture.
Flax seed: Combined with water, this acts as a binder in place of chicken eggs. Chia seeds or a mashed banana could be used in a pinch, but I prefer flaxseed for this recipe.

How to make vegan baked oatmeal

Ground flax with water in a mixing bowl.

Step 1: Preheat your oven, and in the meantime, mix warm water with ground flaxseed and let it sit until it reaches an egg-like consistency.

Step 2: Add the oil, plant milk, syrup, and spices to your flax egg, then whisk everything together until well combined.

Step 3: Whisk in the baking powder, then fold in the rolled oats and any other add-ins you like — chocolate chips are always a good idea!

Step 4: Pour the mixture into a greased baking dish and let it bake until golden. Allow the vegan baked oats to cool for a bit, then serve them with your favorite toppings.

What to serve with vegan baked oats

These baked oats are delicious on their own, but here are a few topping ideas to take them to the next level:

Fresh berries: Blueberries, strawberries, or raspberries all work great.
Nut butter: A drizzle of almond, peanut, or cashew butter adds creaminess and protein.
Yogurt: A spoonful of coconut yogurt adds a tangy and creamy contrast.
Seeds or nuts: Sprinkle on some chia seeds, flax seeds, or chopped nuts for an extra crunch.

FAQ

Why are my baked oats dry?

If you end up with dry oats, it’s likely because you baked them for too long or at too high a temperature. Next time, check them a bit sooner. Regardless, you can always add extra maple syrup or whipped cream to the top.

Can I make this recipe gluten-free?

This recipe is already gluten-free! However, if you have celiac disease or severe gluten sensitivity, make sure you double-check to ensure you’re using certified gluten-free oats.

Why did my baked oats not hold together?

A common reason for this recipe not working is excluding the flax egg. Since it works as a binder, it’s important not to skip this ingredient.
