Ingredients

I made this while quarantined for CoVID19, so some ingredients that I normally would make this oat bake with I was out of or were hard to find at the stores. I listed below the substitutions that I know will work. If you have any questions, comment below and I’ll try to help you out.

  • Oats – I used old-fashioned oats but you can also use instant oats in this recipe, or a combo of 50/50 instant and old-fashioned oats. If gluten-free make sure to use oats specified as gluten-free.
  • Bananas – you want very ripe bananas with lots of brown spots on them for this recipe. The riper they are the sweeter the oat bake will be.
  • Peanut Butter – I used natural peanut butter in this recipe, but any peanut butter, almond or seed butter will work.
  • Milk – I used almond milk as that is what I had on hand. You can use any milk you prefer – regular, oat, hemp, soy or almond.
  • Agave Nectar – this was the only liquid sweetener I had on hand, but honey (for babies over 1 year of age) or maple syrup would also work. You can definitely leave the sweetener out if making for baby or younger toddlers.
  • Egg – I used a regular egg but you can use a flax egg as well.
  • Coconut Oil – I used melted coconut oil in this recipe. You could also use melted butter, olive oil or vegetable oil.
  • Baking Powder
  • Vanilla Extract
  • Cinnamon
  • Salt

How to Serve this Oat Bake

Baby-Led Weaning and Younger Toddlers: Once cooled, crumble the oat bake up (I didn’t add the drizzle of peanut butter to baby’s side of the oat bake) and serve with chopped “pea” size pieces of kiwi and a couple of spoonfuls of plain whole fat yogurt. I love this spoon for feeding yogurt to baby while practicing baby-led weaning. This is also a great breakfast for a toddler as well. This recipe does contain peanut butter, so I would recommend having served baby a small serving of peanut butter to them before serving this recipe so you can make sure they don’t have a reaction to peanuts. Here are some of my favorite ways to introduce peanuts to baby.

Older Toddlers and Kids: serve slices of this oat bake along with chunks of kiwi and a side of plain yogurt with chia seeds and bee pollen sprinkles. You can add a little honey to sweeten up the yogurt.
