3-minute Microwave Oatmeal Cinnamon Breakfast Cake

I make breakfast almost every single day.  During the week, when it’s nothing special, I usually make biscuits or pancakes.  Biscuits take about 15 minutes, start to finish, pancakes take a little less.  That’s not a lot of time, to be honest.  Way less than most people might think.

But even 15 minutes is too much, sometimes, especially on a busy morning.  So I developed this little breakfast cake off my Microwave Chocolate Lava Cake recipe (which is one of my most popular recipes, at least with the search engines.)  It takes about 3 minutes to make, start-to-finish, and it’s baked in the microwave.  The little cake that results is like an extra-moist oatmeal muffin…hearty and fragrant, and will keep you going all morning until lunch.  It’s not going to win any awards for sophistication, but it’s infinitely healthier for you than something processed from the freezer, and it’s embarrassingly easy to make.  I always think of my buddy Rachael Ray when I develop a recipe like this.  Being on her show was such fun, and while she doesn’t claim to be a chef, I think her convenient recipes have made a HUGE difference in the lives of many people who wouldn’t otherwise cook for themselves.  I also think about Alton Brown, because he’s such an amazing food geek who loves using technology to make cooking more interesting and efficient.  So this recipe is dedicated to them.

In a large measuring cup, combine:

4 Tbsp all purpose flour
4 Tbsp oats (old-fashioned will give a heartier texture than quick oats, but either are acceptable)
3 Tbsp brown sugar (light or dark, or sub regular sugar if you don’t have it)
1/2 tsp cinnamon
pinch salt
pinch baking powder

(You could also add some nuts or raisins if you wanted to!) 

Stir this around with your fingers until it’s well mixed.  Then add:

1 egg
1 Tbsp canola oil
3 Tbsp buttermilk (sub regular milk if you don’t have it)
1 tsp vanilla

Stir with a fork until all the ingredients are well mixed.  Then take 2 glass tumblers and spray them lightly with cooking spray.  Divide the batter between the 2 tumblers:

Place the tumblers in the microwave and nuke them on full power for about 2 minutes.  This is the only tricky part, because everyone’s microwave is powered differently.  So the first time or two you make this, you may underbake or overbake your cakes, but you’ll figure out your microwave’s “sweet spot” after a time or two.  When the batter is rising and reaches close to the top rim of the glass, let it go another few seconds and stop it.  (My microwave does this in exactly 115 seconds.)  Let the cakes sit in the microwave for at least 30 seconds.

CAREFULLY remove the screaming-hot glasses from the microwave with a glove or hot pad and invert them onto the serving plate.  The cakes will drop down onto the plate.  If you’re not serving them immediately, wait to remove the glass until serving time, which will keep them warm.

Drizzle with maple syrup, and you’ve got the easiest homemade breakfast you’ve ever made!

UPDATE:  Take this cake up to a whole new level by adding a decadent meltdown!  Just before putting the batter in the microwave, add a big spoonful of dulce de leche or caramel sauce, or any fruit jam, right on top.  As the cake begins to bake, the meltdown will slowly sink to the bottom and heat up.  As the cake sits in thee microwave, it will absorb some of the meltdown.  When you invert the cake onto the serving plate, the rest will become a decadent sauce that will ooze down over the cake, making this easy-as-can-be breakfast extra decadent!

    Ben, this sounds wonderful! As someone who is “cooking impaired,” could you tell me if I’d need to make any changes to the recipe to allow for high altitude (6000 ft)?

    1. Ben Avatar

      Nicki, I don’t think there will be any difference in the recipe due to how rapidly the cakes cook in the microwave, and how small the microwave chamber is, which holds in the moisture. The biggest problem with baking at altitude is that water evaporates faster in the lower pressure, which not only dries out your dough or batter, but can cause an uneven rise because the water vapor vacates the batter so quickly. This is a more dense, moist cake regardless of altitude because of the rapidity of evaporation in the microwave.

    I don’t like microwaved food but love the idea of your breakfast cake. How would I adjust to bake it in the toaster oven?

    1. Ben Avatar

      Allison, I would not try to bake this in the toaster oven. This recipe is developed specifically for microwave cooking. Baking in the oven or toaster oven would take the same amount of time as a traditional muffin or cupcake, so it would be best to use a conventional recipe if you’re doing traditional baking.

    I will definitely try this. I desperately need to improve on getting my children to have a quick, healthy breakfast. And I love it when the microwave gets used for “real cooking.” Speaking of Alton Brown, I have made a habit out of his whole wheat pancake freeze-and-toast-as-needed technique

    I whip us some peanut butter in the Vitamix, then top with local peaches and honey. Now that’s a quick breakfast worth having any time of day!

      Nick, that sounds FABULOUS! And ya gotta love Alton. He is the reason I started cooking seriously.

    As a tentative cook I really appreciate your recipes and that you break down the why and the how of the important steps in your recipes. We’ve got allergies in our family, so I’m going to try this with an all purpose gluten free flour (got a lb of Bob’s Red Mill which I’ve never tried; it’s a mixture of Garbanzo Bean, Tapioca, White Sorghum & Fava Bean Flour s and Potato Starch). Almond or Rice Milk instead of Buttermilk :'( and perhaps may need to cut the sugar with applesauce. Any advice?

    Can you substitute unsweetened applesauce for the oil, and if so, how much would you use? Also, how much egg white instead of an egg? Thanks!

    1. Ben Avatar

      Maria, I’d substitute the same amount of applesauce, and 2 egg whites. Let us know how it turns out for you!

    The receipe sounds great. I have one major problem….I’m allergic to milk, not lactose intolerant, but allergic.
    What would you recommend for me as a good milk sub. for this receipe.
    Thanks in advance, Rachel

    1. Ben Avatar

      Rachel, ANY normal milk substitute will work just fine in this recipe…almond, soy, rice, coconut…

        Thanx Ben, I was just worried that one of the milk substitues would affect the flavor. I will give it a try.

    Once you figure out the proper time in the microwave, take a look at the label inside the door and take note of the POWER OUTPUT. This will give you what you need to calculate the energy needed to cook your dish. THEN if you have a different microwave, you can do the math to figure out the new time.

    I have to try the “3-minute Microwave Oatmeal Cinnamon Breakfast Cake”, What get’s me tho, it’s always said it takes less time to cook this or that yourself! HOWEVER, for those of us that have to do the clean-up, it’s MUCH longer when adding the messy clean up. Just had to get that off my chest.

    1. Ben Avatar

      Sharene, the great thing about this recipe is that you only have 1 measuring cup, 1 measuring spoon, and 2 glasses to clean afterward!

    Ben! This is such a great idea for school breakfasts! We are always in such a rush around here (duh, that’s what it is to have 4 kids lol), this would be a great way for me to give them something quick and healthy. Thank you!!!

    1. Ben Avatar

      My pleasure! You can easily double this recipe for 4 kids, but the cakes will need to stay in the microwave a bit longer if they are all baking together.

    I’ll have to try it once I finish my diet! Also, I’m curious to what you think could be healthy and really tasty food for dieters.

    I made this for myself and my toddler this morning. I set the timer for 2 minutes as instructed, but it started to rise and go over the top with FORTY-EIGHT seconds remaining! It came out kind of “gummy” but had a good flavor. What did I do wrong? BTW, my little one loved it and ate BOTH cakes. 🙂

    1. Ben Avatar

      Bonnie, it’s a microwave cake, so it’s going to be a little gummy. The starches explode much more quickly in the microwave than they do in the oven when they are slow baked. That’s what it tastes like. That’s why I said it wouldn’t be winning any awards for sophistication! Ha ha ha… Leaving the cakes in the microwave a little longer will dry them out a bit more, resulting in a less gummy texture.

    Just tried this morning and Pinned it after the first bite! First cooked for 1:15, took a peek and the went 20 seconds more. Awesomeness!!! I may have went over the 15-minute mark, but after a few more times, this will be a breeze. Being someone who does eat breakfast unless its a Saturday or Sunday morning simply because of the time factor, this is a great idea. There’s a cookbook challenge for you: Breakfast in 15 Minutes or Less!

    I finally made them today (August 22), Ben. And all I can say is… It’s addictively good.

    I just made these with rice milk, whole wheat flour and homemade vanilla extract… So dreamy. I could get excited about these any time of the day. I just finished watching season 2 of MasterChef yesterday and was pretty bummed when Ben Starr got sent home, but SO excited to find some of your recipes online! Thanks!!

    how do you think sweetened condensed milk would be instead of dulce de leche?

    1. Ben Avatar

      Lisa, sweetened condensed milk would be just fine! (You know, you can turn sweetened condensed milk into dulce de leche, right? It’s super easy if you have a pressure cooker…)

    I just made these things. They’re pretty good for a ‘microwave’ food, even though I did put too much cinnamon in. I was walking back and forth to look at the recipe because I didn’t feel like printing it out, so instead of 1 tsp of cinnamon I used 1 tbsp.
    They’re really filling as well, I was only able to eat 1 and I was done. Good if your on a diet! 🙂

    Excellent! I reduced the brown sugar to two tablespoons, and added a tablespoon each of dried cranberries and chopped walnuts. Will be making this again. Thanks!
