Vegan Baked Oatmeal – Cozy, Customizable & Naturally Sweetened

Warm, hearty, and perfect for meal prep, Vegan Baked Oatmeal is the ultimate fuss-free breakfast. It’s a cross between traditional oatmeal and a breakfast bar — soft, slightly chewy, and filled with the natural sweetness of fruits, spices, and plant-based goodness.

Made with rolled oats, non-dairy milk, flaxseed, and a touch of maple syrup, this baked oatmeal is naturally vegan, dairy-free, egg-free, and easily gluten-free with certified oats. You can flavor it with bananas, berries, apples, or chocolate — it’s endlessly customizable and great for kids and adults alike.

Whether you’re feeding a family or prepping for the week, vegan baked oatmeal is a reliable, wholesome way to start your day.

Ingredients Overview

Base Ingredients:

• Rolled Oats (Old-Fashioned):

  • Heart-healthy whole grain that gives structure and chew. Avoid quick oats, which become mushy.

• Ground Flaxseed:

  • Acts as an egg replacer and adds omega-3s and fiber. Combine with water to make a flax “egg.”

• Plant-Based Milk:

  • Almond, oat, soy, or coconut milk all work well. Unsweetened varieties give you control over flavor.

• Maple Syrup or Agave:

  • Natural sweetener with warm undertones. Adjust to taste depending on your mix-ins.

• Coconut Oil or Neutral Oil:

  • Adds moisture and richness. Can be omitted for an oil-free version with applesauce.

• Baking Powder:

  • Provides lift and helps the oatmeal bake into sliceable squares.

• Cinnamon & Salt:

  • Boosts flavor and balances sweetness.

Optional Add-Ins:

• Mashed Banana or Applesauce: For natural sweetness and moisture.

• Berries: Blueberries, raspberries, or strawberries add juicy bursts.

• Nuts/Seeds: Walnuts, almonds, pumpkin seeds for crunch and healthy fats.

• Chocolate Chips: Use vegan chocolate for a treat-style breakfast.

• Shredded Coconut or Raisins: For extra texture and variety.

Step-by-Step Instructions

1. Prep the Oven & Dish

• Preheat oven to 375°F (190°C).

• Lightly grease an 8×8-inch or similar baking dish or line with parchment paper.

2. Mix the Flax Egg

• In a small bowl, combine:

  • 1 tablespoon ground flaxseed

  • 3 tablespoons water

• Let sit for 5 minutes to thicken.

3. Combine Wet Ingredients

In a large mixing bowl, whisk together:

• 1¼ cups plant-based milk

• ¼ cup maple syrup (or to taste)

• 2 tablespoons melted coconut oil or applesauce

• ½ cup mashed banana or applesauce

• 1 teaspoon vanilla extract

• Prepared flax egg

4. Add Dry Ingredients

• Stir in:

  • 2 cups rolled oats

  • 1½ teaspoons baking powder

  • 1 teaspoon cinnamon

  • ¼ teaspoon salt

• Gently fold in any mix-ins (½ cup berries, ¼ cup chopped nuts, etc.).

5. Transfer & Bake

• Pour the mixture into the prepared baking dish and spread evenly.

• Top with extra berries, banana slices, or a sprinkle of nuts/seeds if desired.

• Bake for 35–40 minutes, or until set and golden on top.

A toothpick should come out mostly clean, and the edges should be lightly crisp.

6. Cool & Serve

• Let rest for at least 10 minutes to firm up before slicing.

• Serve warm with a drizzle of maple syrup, a spoon of nut butter, or a splash of plant milk.

FAQs

Q1: Can I make this baked oatmeal gluten-free?

Q2: Can I freeze baked oatmeal?

Absolutely. Slice and freeze in a single layer, then store in a container or bag. Reheat in the oven or microwave.

Store baked oatmeal covered for up to 5 days. Reheat individual portions in the microwave or oven.

Yes. Skip nuts and use nut-free milk (like oat, soy, or rice milk).

Q6: How can I make this higher in protein?

Add vegan protein powder, hemp hearts, or swirl in some almond or peanut butter.

Q7: What’s the texture like?

It’s soft and lightly chewy, almost like a cross between cake and oatmeal. Let it cool slightly to firm up before slicing.
