Recipe Modifications & Ingredient Swaps
While this vegan oatmeal recipe tastes delicious as is, here are some easy ways you can modify this recipe to suit your needs:

Instead of peanut butter, try this with another nut butter like almond or cashew butter. I made it with almond butter too, and I LOVED it!
I used almond milk for this recipe, but feel free to swap that with your milk of choice (cow’s milk, soy milk, cashew milk, etc.) My only advice is to choose one that’s unsweetened.
If you don’t have walnuts, you can easily replace them with pecans – they’ll taste just as good. A sprinkle of coconut chips on top would also taste divine!
For a nut-free version, you could try swapping the peanut butter with sunflower seed butter instead. As well, omit the walnuts on top.
If you follow a strict gluten-free diet, be sure to use certified gluten-free rolled oats.
If you’re a strict vegan, make sure to use vegan (dairy-free) chocolate chips. I like these ones!

How To Store & Reheat Baked Oatmeal
While it tastes best straight from the oven, baked oatmeal can be an excellent addition to your weekly breakfast meal prep routine!

Baked oatmeal can be stored in an airtight container in the fridge for 4 days. If you’d like to further extend the shelf-life of baked oatmeal, it can be stored in the freezer for up to 6 months.

The easiest way to reheat baked oatmeal is in the microwave.

TIP: You may find that the leftover oats have absorbed more of the liquid over time, making them a bit dry. Simply add a splash of milk of choice and give it a stir before reheating!

Peanut Butter Nutrition Benefits
Peanut butter is an awesome source of heart-healthy fats and plant-based protein.

It’s also packed with other nutrients like:

magnesium
vitamin B6
iron
phosphorus
niacin
TIP: be sure to go for the unsweetened variety of peanut butter. I always look for brands where the only ingredient is peanuts!

Banana Nutrition Benefits
Bananas are a great source of fibre – one medium banana provides 3g of fibre

They’re also a good source of micronutrients like:

potassium
vitamin C
vitamin B6
magnesium
Oatmeal Nutrition Benefits
Rolled oats are a great source of dietary fibre and plant-based protein.

Oats contain a ton of B-vitamins, like thiamin, folate, and pantothenic acid.

Ingredients

3 medium bananas, ripe
2 cups almond milk, unsweetened
1/2 tsp vanilla extract
1/2 cup peanut butter, unsweetened
2 cups rolled oats
1 tsp baking powder
1 tsp ground cinnamon
Pinch of salt

Preheat oven to 375F.
In a large mixing bowl, peel and mash two of the bananas.

Next, add the rolled oats, baking powder, ground cinnamon, salt, and chocolate chips to the banana mixture. Whisk again, until all ingredients are well-combined.
Pour the mixture evenly into a baking dish (I used a 9″x 6″ one) and add remaining banana (cut into rounds) on top. Then, sprinkle walnuts on top before placing the baking dish in oven for 30 minutes.

Remove oatmeal from oven and allow to cool for a few minutes before serving. Enjoy hot!
