In this Post: Everything you need for The ULTIMATE 90 Second Microwave Oatmeal

Cold winter weather begs for a warm and hearty breakfast. In our house, that usually means we rotate between freezer pancakes and oatmeal.

While I’ve shared countless oatmeal recipes with you over the years, it dawned on me that I’ve never shared the one recipe I make most: The ULTIMATE 90 Second Microwave Oatmeal!

90 Second Oatmeal Recipe

Not only is oatmeal extremely nutritious and versatile, but it is also gluten-free. For those of you with a gluten allergy, I highly recommend Bob’s Red Mill Gluten Free Oats made in their 100% gluten-free facility and tested for gluten again to ensure their purity. In fact, I got to tour the factory and see this process up close and personal during my visit to Portland last year!

Pouring Milk

Frequently Asked Questions:

What are the best oatmeal toppings to choose from?

The best topping for oatmeal is peanut butter for protein, berries, oats, banana slices, chia seeds, almonds, or raisins.

What is the ratio of oats to milk for oatmeal?

I typically do a 1:1 ratio. One cup of oats to one cup of milk but if you want the oats to be looser I would suggest adding a little more milk.

Can quick-cooking oats be used in the microwave?

Quick-cooking oats in the microwave will make things super mushy to the point you won’t feel like eating breakfast. If you want perfect oatmeal you need to use old fashioned oats.

How do you make hot oatmeal kid-friendly?

Many times oatmeal coming out of the microwave is too hot for kids. If you want to cool it down quickly, mix in some frozen berries when it comes out of the microwave. That will bring the oatmeal down to the right temperature for the kiddos.

What types of milk can be substituted in oatmeal?

If you’d like you can substitute rice milk or water for whole milk. You would substitute with the same quantity of whole milk in the recipe.

Your spoon is waiting.

  1. I thought this was delicious. I like my oatmeal chewy but wet, so I just poured skim milk in the bowl before I ate it, which is what I always do, stovetop or microwave. The vanilla was a brilliant idea! And 1/4 tsp of cinnamon was perfect. One question though. Can I use skim milk for the cooking part, instead of whole milk? I don’t want the extra calories. With milk to thin it, chopped walnuts, sliced banana, and a small squeeze of honey, it was my perfect breakfast, without dirtying that horrid oatmeal pot! Thank you so much. This will be on my regular rotation.

  2. This makes mornings so much easier! I have one early riser who wants to eat as soon as she wakes up and a son who likes to sleep in—now everyone can make their oatmeal when they’re ready for it. Thank you for the great idea. (And we loved the addition of the vanilla! We’ve never tried that before, and it was great!)

        Sooooo good!! Excited for this to be my go-to breakfast!! I added chocolate chips as a sweetener and it turned into this delicious gooey heaven, perfect consistency!!!

  3. It was great! Add some chocolate melting wafers halfway in, and your whole morning turns into chocolate heaven…

  4. I didn’t read all the comments, but I think this is a brilliant idea! I needed to cook mine in my microwave for almost double the time and added a bit more milk. And I prefer chewy oatmeal. But this saves me from having to wash that oatmeal pot, which almost ruins the joy of eating oatmeal! So thank you for such a great idea.

  5. The ingredients that is shown has “1/2 cup of whole milk” vs 1 cup whole milk which I believe is the correct amount. The ratio of liquid to oatmeal is “2 to 1” whether it be milk, water or other choices like coconut or almond milk.

  6. I just made mine and for a lazy person this was the most spectacular experience I’ve ever encoutnered. I have celiacs disease and finding alternatives is expensive and restaurants don’t usually provide options for people like me. Loved this to its absolute pleasure. Thank you.

  7. Tried with quick oats and didnt come out right .so i 50/50 the mix and it was perpect ! i also lost the vanalla but each to there own great recipe thanks ROBERT

  8. I noticed no one actually commented on this recipe after they made it. I’m here to give my honest opinion: I made this and it was TERRIBLE! You need to take a look at the measurements because something is seriously wrong with this! First of all, there is way too much milk in it, mine turned out watery and not cooked. It would have to cook a lot longer than 90 seconds to look like the pictures. Secondly, 1/2 teaspoon of cinnamon is a lot for a little bowl of oatmeal! Maybe some people like that much cinnamon, but I found it to be very overwhelming! Lastly, there is WAY too much salt in this! It seriously tasted like play dough! I ended up throwing the whole thing out! I found this recipe on Pinterest and I’m sorry to say it’s the worst recipe I’ve ever made from there! Sorry but this is my honest opinion and I hope this review will stop others from wasting the ingredients to make this!

    1. Hi Amber – First of all, thank you so much for taking the time to leave your honest feedback. I truly appreciate it and know how frustrating it can be when a recipe doesn’t turn out as expected. Second, I am sorry you didn’t enjoy the oatmeal. I ended up changing the recipe to 1/4 teaspoon cinnamon to reflect your suggestion as I realize not everyone likes it as strongly spiced as I do. With regards to the 1 cup of liquid to 1/2 cup oats, that is a formula I’ve always used but I understand it might not be your preference. Either way, I apologize that this didn’t turn out as you expected and hope you’ll try it again perhaps adding salt and cinnamon to taste.

      1. Just ran across this recipe tonight while searching for a quick breakfast in the morning. I need a change from my smoothies. I hate mornings and didn’t want to be disappointed in the morning so decided to try it for a midnight snack. The flavors are great! It’s runny and I’m wondering if it’s the oats I used, old fashioned versus quick cooking. Which would you consider Bob’s?

      2. We tried it and it was great. Rather then slam people on the net who take time to share and offer their kindness, perhaps a kinder response could be less dramatic and provide valuable insight to the people that take their time to share with the rest of us. Thank you for sharing and taking time to do this. If you have an opinion which stems from a negative place, please Think twice Before posting. Perhaps Mediation is your best recipe.

    2. I have to agree with you here Amber – this was absolutely disgusting, something is off with the ratios-it was a liquid flavorless mess that went straight into the trash after first bite. Maybe it’s the salt? I’ve never heard of salt in oatmeal unless it’s a savory oatmeal, but overall the flavors were so bland, definitely not ‘ultimate.’

      1. I am so sorry you didn’t enjoy this Li! I always add salt to oatmeal but you are always welcome to leave it out. I find the salt helps balance the flavors of the cinnamon and vanilla and creamy oats made with milk. Regardless I apologize you didn’t like it!

  9. This is so great! I’ve finally convinced my 4-year-old that he does, indeed like oatmeal. So we’ve been making it a lot. Love this quick version.

  10. I love adding a touch of peanut flour or protein powder to my eggs after they are in the microwave if I don’t have milk around (like at the office). It helps make them super creamy! I love this simple method though :)
