Oatmeal has been a staple in our house ever since my oldest was a baby and I learned how easy it was to make baby cereal at home. Yes, you can buy baby oatmeal, but I find that it usually smells (and tastes) a little funny, and it can be expensive.

This version of baby oatmeal, which is so easy to make and actually tastes like oatmeal, is a great baby food option. My kids loved this when they were new eaters!

To make this recipe, you just need old-fashioned oatmeal and water. To make organic baby oatmeal, start with certified organic rolled oats. To make gluten-free baby oatmeal, start with gluten-free rolled oats.

TIP: You can use breastmilk or formula instead of the water if you prefer. As baby grows, you can use plain unsweetened nondairy milk too, then cow’s milk over age 1.

Here’s a look at the easy process of making this DIY baby cereal recipe. Scroll down to the bottom of the post for the full information.

  1. Add the oats to a blender. Grind, starting on low and working up to high, until the oats form a fine powder-like flour.
  2. Add some ground up oats to a heat-safe bowl.
  3. Add a little hot water and stir. Add more to thin to desired consistency depending on baby—thinner for newer eaters, a little thicker as they become more comfortable with texture
  4. Stir in optional flavorings and nutrients.

TIP: You can start off making this thinner as a Stage 1 baby food, then gradually add less water to make a thicker Stage 2 baby food.

How should I serve this to my baby?

You can offer a small amount on a spoon, then stop offering it when baby closes their mouth or turns their head as those are signs that baby is done. Or you can put a little on a spoon and hand the spoon to baby to feed themself.

Can I use different grains?

Sure! If you have a high powered blender—I love my refurbished Vitamix—you can grind almost any grain into a powder, then add water to turn it into baby cereal. Try brown rice, quinoa, millet, and the like.

That way can take some practice, but they usually love having more involvement in the eating process!

Can I make this with regular rolled oats?

Yes, that’s the beauty of it since you probably already have them in your pantry! Or if you only have quick or instant oats, you can use those too. You just won’t have to grind them up as long.

To store any leftovers, simply place into a small storage container and store in the fridge for up to 3 days. Add a little hot water to thin out (it will thicken in the fridge) and serve.

Optional Flavorings to Add to Baby Oatmeal

Here are some ideas for what you can stir into baby oatmeal to make it more flavorful and nutritious for baby. Babies need healthy fats, iron, and to be exposed to a range of flavors, so these are some great options to work into the mix.

Add about 1-2 tablespoons of each puree and 1/2-1 teaspoon of the flaxseed to each serving of oatmeal.

TIP: Store bought baby cereal is typically fortified with iron, so if you want that option, consider adding some infant iron supplement to the finished oatmeal. Check the bottle for recommended dosages, do not exceed the recommended daily dose, AND be sure to talk it over with your pediatrician as well. (This post is not meant to be a substitution for medical advice.)

Best Store Bought Baby Oatmeal

I love the Amara Organics Oats n’ Berries (paid affiliate link). It has a delicious berry flavor and 50% less sugar than other similar products and it mixes up so super fast that it’s a nice option to have on hand for fast meals for baby.

Best Tips for Success

  • To make organic baby oatmeal, start with certified organic rolled oats.
  • To make gluten-free baby oatmeal, start with gluten-free rolled oats.

  • 1 cup old-fashioned rolled oats
  • 2 tbsp water, breastmilk or formula
  • cinnamon, ground ginger, or baby food purees (see NOTES for options)


  • Add the oats to a blender. Secure the lid and grind, starting on low and working up to high, until the oats form a flour-like powder.
  • Add 1 tablespoon of the oat powder to a heat safe bowl. Stir in about 2 tablespoons very hot water (or warm breastmilk or formula), adding more as needed to thin to desired consistency. (Start thinner, so the mixture is easy for baby to move around in their mouths—it should not be sticky for new eaters. You can gradually use less liquid as baby becomes more comfortable with solids.)
  • Add any optional flavorings. Serve with a spoon or offer a preloaded spoon to baby to feed themselves, stopping the meal when they turn their head or close their mouth.
  • Store the remaining ground up oats in an airtight container.

How many stars would you give this recipe?


  1. The ingredient list and instructions don’t match. The ingredients says 1 cup of oats and the instructions says 1 Tablespoon.

    1. You make the ground up oats, then you use a smaller amount to make each serving. You can’t blend up 1 tablespoon at a time, so you need to start with the larger amount and simply store it to use as you need it. I hope that helps.

    Hi! I like the idea of adding purées to the oatmeal. My daughter is 9 months old and she is a very picky eater. Oatmeal seems to be the only thing she really likes. She can tolerate butternut squash and yams but she hates all fruit so far.

    I was wondering how much purée you add to the oatmeal? Also, do you have any other tips on how to make fruit and veggie purées tastier? I haven’t added any spices to her food and I’m not sure when I can add them since I know the Dr. said to introduce one food at a time.

    Thanks for you help and thanks for sharing your recipes! 🙂

    1. Hi- For about 1/4 cup oatmeal, I’d do 1-2 tablespoons of the fruit puree. You could add cinnamon to any flavor and then for savory foods, you can add things like ginger, cumin, italian seasoning, oregano—whatever you like. There’s not really an allergy concern with spices so you have a lot of options as long as you avoid hot spice. I hope that helps a little!

    Hi, thanks so much for the recipe. I just wanted to clarify I am sing quaker oats large flakes oats. I grind them up like you said and wanted to verify that I don’t have to cook them before giving to them to the baby that I can just add hot formula to them. Thanks in advance

    1. When the oats are ground into a fine powder, they cook almost instantly with hot liquid. I hope that helps!

  4. 5 stars
    Thank you so much for this tip. I want to know if i have to add cinnamon powder to either the rice or oat, should i add it to the powdered content before adding formula or water? Also, what portion of cinnamon is advised?

    1. You can stir it in as you add the liquid. A tiny pinch, like a 1/8 teaspoon at most would be a good place to start.

    Thanks for the tips! I use the instant oatmeal and add milk. Should I be blending it first? Does blending help with digestion? Thank you

    Hello! Your directions state to just add water or warm breastmilk to the oats- do you not have to cook these? Could you properly cook them on the stove? Or is that not needed? Just wondering because the current beachnut oats baby brand I am using states the oats are already cooked, so I wasn’t sure if that was a needed step to make the oats “safe” for baby? Thank you!

    Would this recipe work with any puréed fruit/veggie? My little guy likes a variety of mixed fruits and veggies. Thanks!

    1. Yes it should, though I’d avoid veggies with strong or bitter flavors unless you know your kiddo likes them. Have fun trying out other options!

    Can I freeze the oatmeal? If I make it over the stove and add the squash and coconut milk, would it be good to freeze?

    1. I’d probably freeze it without the milk just in case it separates when you thaw it, but it should be okay otherwise.

    Very yummy idea! My little man loves steel cut oats for breakfast, and I always try to add in something “extra” like a fruit or even pumpkin! I make my steel cut oats overnight in the crock pot – definitely adding pureed butternut squash next time!
