Ingredients needed to make this baked oatmeal recipe
This delicious and healthy peanut butter banana baked oatmeal is made with simple ingredients that you likely already have on hand. You’ll need:
- Flax egg: We’re combining 2 tablespoons of ground flaxseed and 1/3 cup warm water to replace two eggs in this recipe.
- Quick oats: For the best texture, we recommend quick oats in this particular baked oatmeal recipe. Use gluten-free oats as needed.
- Baking powder: To help it rise a little and not turn out completely flat.
- Salt: You always need just a bit of salt in a sweet dish like this to balance the flavor. We prefer kosher salt, but you can use table salt or sea salt.
- Flavor makers: Pumpkin spice mix and vanilla extract add warmth and cozy flavor.
- Bananas: This ingredient makes this dish perfectly moist and sweet. Be sure to use very ripe bananas!
- Peanut butter: Such delicious flavor! Feel free to use crunchy, if you like a little extra nutty crunch in your oatmeal. We recommend the natural kind, made from just peanuts and salt.
- Honey: To naturally sweeten the dish. Maple syrup or agave would work great as a substitute.
- Milk: We like to use coconut milk, but you can use any milk you’d like.
- Peanuts: The addition of chopped unsalted roasted peanuts really takes this baked oatmeal to the next level. However, you can omit it if preferred.
