You all enjoyed my Pumpkin Baked Oatmeal so much I immediately knew I wanted to create another flavor variation, which happens to be my favorite combo of all time: Nut butter, banana, chocolate!

It’s so easy and comes together in 1 bowl with 10 ingredients you likely have on hand right now. Let’s bake!

This baked oatmeal starts with a flax egg and mashed ripe banana. It’s then naturally sweetened with a little maple syrup, seasoned with cinnamon, and moistened with dairy-free milk and a little oil (which can be omitted or subbed with applesauce if needed).

Next comes oats, nuts, and dark chocolate! We also recommend adding a little nut butter on top for garnish to give each serving even more richness. Plus, bananas and nut butter just belong together.

After an optional sprinkle of coconut sugar for a brûlée effect, it’s into the oven for a 30 minute bake. And just like that, breakfast is on the table!

We hope you all LOVE this baked oatmeal! It’s:

Reminiscent of banana bread
Naturally sweetened
& SO delicious

This would make a delicious lazy weekend brunch to enjoy with friends or family. It would also be a satisfying breakfast to bake ahead of time and warm up in the mornings before work! I think it would travel especially well in a mason jar or glass container with a little dairy-free milk to be reheated at the office!

Does it keep? 3-4 Days


  • 2 Tbsp flaxseed meal*
  • 5 Tbsp water
  • 1/2 cup mashed ripe banana (the riper the better // plus more sliced banana for topping)
  • 2 Tbsp maple syrup (or sub coconut nectar or agave nectar)
  • 2 Tbsp melted coconut oil or avocado oil (if avoiding oil, sub applesauce or omit)
  • 1/4 tsp sea salt
  • 1/2 tsp ground cinnamon
  • 2 cups dairy-free milk (we used 1/2 almond milk, 1/2 light coconut milk)
  • 2 ½ cups gluten-free rolled oats
  • 3/4 cup chopped walnuts or pecans (or sub other nut or seed of choice)
  • 1/3 cup dairy-free dark chocolate chips (or chopped chocolate // use naturally-sweetened to keep recipe refined sugar–free)
  • 1-2 Tbsp coconut sugar (optional)
  • 2-3 Tbsp nut butter (optional)


  • Preheat oven to 350 degrees F (176 C) and grease a 2-quart (or similar size) baking dish with oil (or vegan butter), or line with parchment paper.
  • Prepare flax eggs by combining flaxseed meal and water in a large mixing bowl. Then add ripe banana, maple syrup, oil, salt, and cinnamon and whisk to combine.
  • Add dairy-free milk and whisk once more. Then add oats, nuts, and half of the chocolate chips and stir to combine. 
  • Transfer mixture to the prepared baking dish and top with additional banana slices, nuts (optional), and remaining chocolate chips. Sprinkle with coconut sugar for a “swirl” effect (optional). You can also drizzle with a little nut butter — such as almond or peanut — for even more flavor (optional).
  • Bake for 30-35 minutes or until the top is golden brown, the edges are slightly caramelized, and it has some springiness in the center. Remove from oven and let cool a few minutes.
  • Serve warm with desired toppings, such as warmed coconut milk or almond milk and a drizzle of maple syrup or additional nut butter.
  • Store leftovers covered in the refrigerator 3-4 days (or in the freezer up to 1 month), though best when fresh. Reheat in a 350-degree F (176 C) oven or in the microwave until hot, adding more dairy-free milk as needed to moisten.



*If subbing eggs for the flax eggs, we’d suggest using 2 eggs in place of the 2 Tbsp (14 g) flaxseed meal and 5 Tbsp (75 ml) water.
*This recipe can also be baked in smaller ramekins for ~20-25 minutes.
*Nutrition information is a rough estimate calculated with coconut oil, half unsweetened almond milk and half light coconut milk, and walnuts, without optional ingredients.

    I eat this for breakfast most weekdays by prepping it on Monday morning.

    I replace the oil with a nut butter and often add berries/ other nuts to the top. Nice adaptable recipe thank you!
