Hi, friends. Let's talk mug cakes, shall we?

Y'all are apparently fans, because the two mug cake recipes I've shared so far on the site get regular features, lots of rave reviews, and have comfortably secured spots in Five Heart Home's lauded top 20 recipes of all time. 😉 The mugs cakes I've previously posted, however, were dessert recipes -- namely, a decadent Chocolate Peanut Butter Mug Cake and a sugary Snickerdoodle Mug Cake. But I recently thought to myself...wouldn't it be fun to change things up a bit and come up with a breakfast mug cake?

I basically took my aforementioned Snickerdoodle Mug Cake recipe and my Classic Blueberry Muffins recipe and combined the best elements of both.

The result is a blueberry muffin in a mug that's quickly assembled before being baked in the microwave for a minute or two. The Cliff Notes version? This recipe turns out a fresh, warm muffin that tastes like cake...which means it's pretty much guaranteed to be your new favorite breakfast treat!

No Egg!

As with my other mug cakes, there's no egg in this one, which prevents the texture from turning rubbery in the microwave. It also means that if you prefer your blueberry muffin slightly undercooked in the center, you don't have to worry yourself with any raw egg concerns.

Recommended Mug Size

Additionally, I've found that a mug cake does best in a straight-sided mug that allows it to cook evenly and rise without overflowing (these white, 14-ounce mugs happen to be my go-tos for perfect mug cakes...which is why you may notice all of my mug cake posts looking eerily similar... 😀 ).

Cooking Time

All microwaves vary in strength, so be prepared to experiment a bit with cooking duration any time you make a new mug cake recipe.

This Blueberry Muffin Mug Cake does seem to take a bit longer to fully bake than my other mug cakes, presumably because of its plethora of juicy berries.

Feel free to reduce the amount of berries used if you wish...but I'm not sure why you'd want to. 😉

Close-Up with spoon digging in. Okay, enough of my yammering. I think it's obvious enough that this speedy recipe will yield a tantalizing, blueberry-studded breakfast or snack in about the same amount of time it would take you to whip up a bowl of oatmeal. And doesn't a Blueberry Muffin Mug Cake sound way more exciting than oatmeal???

  • ¼ cup + 2 tablespoons all-purpose flour
  • 2 tablespoons sugar
  • ¼ teaspoon baking powder
  • ¼ cup milk, at room temperature
  • 2 tablespoons salted butter, melted and cooled
  • ½ teaspoon pure vanilla extract
  • ¼ cup fresh blueberries
  • Coarse sparkling sugar, optional garnish


  • In a small bowl, whisk together flour, sugar, and baking powder until thoroughly, completely combined, with no streaks of any ingredients remaining. Blend in milk, butter, and vanilla until batter is smooth. Stir in blueberries and pour batter into a 14-ounce (or larger) microwave-safe mug with straight sides. Sprinkle with sparkling sugar, if desired.
  • Microwave on high for 1 ½ to 2 minutes, or until cake is done to your liking. Allow to cool for a couple of minutes before serving.


  • As soon as you transfer the batter to the mug, cook the cake immediately so that the blueberries don't have time to sink to the bottom.
  • A tall, cylindrical mug with straight (not angled) sides will ensure that the cake bakes evenly. I found a 14-ounce mug to be the perfect size to allow the cake to rise up while baking without overflowing. (I filled my mug to the top with water and then transferred the water to a measuring cup to determine its capacity.) If you use a smaller mug, you may want to bake the cake on top of a plate or paper towel to catch any possible overflow.
  • The strength of individual microwaves can vary. The first time you make this recipe, be prepared to experiment a bit to ensure the perfect length of baking time for your particular microwave. The nice thing about this cake is that even if it is undercooked, you don't have to worry about raw eggs!
  • Unsalted butter will work just fine in this recipe, but I find that using salted butter adds a tiny flavor boost.

    This recipe was super easy to make! I added some cinnamon and it was pretty good! Next time I would add more sugar.

    This one was okay. It was not my fav, did not finish it all through. but it was alright. I liked the snickerdoodle one a lot better, and the poppyseed one too. guess this one's just not my thing. oh well... 😏 or maybe I did it wrong?😕

  3. 4 stars
    Only change I would make is to add maybe 1/4 tsp salt and as always (my opinion), some nuts! It was a lovely treat..who would've thought we'd go from large pans of gooey goodness to a 5 minute ready treat!! We grew up eating it with milk poured over it, perhaps some cheese for a slightly salty, protein that's how I ate it. Of course ice cream is better than milk.. you wouldn't know looking at me how often I've say no to the stuff.. :/

    This is my favorite mug recipe and it tastes just how it would come out from the oven! Tbh I even liked it better than the oven recipe!

  5. me and my son tried this for his classwork "make breakfast for yourself" and it was not muffin at all it was very dense didnt fluff or have any sweet taste like a blueberry muffin. I might try it again just to see if we did something wrong

    I replaced half the butter with coconut oil and used whole grain flour and it was so good! definitely going to make again.

    Brilliant! I used defrosted frozen raspberries instead and it was absolutely delicious. Would recommend, but could there be measures in grams please because I do not usually use the cup measurement system normally.

    I was tired of having cereal for breakfast and stumbled alum this recipe. It’s so delicious I make it almost every morning now. It’s great because the muffin doesn’t stick to the mug even when you don’t spray the mug so it’s makes for an easy cleanup 🙂

    Hi, I’ve just discovered your site. I’m THRILLED with the no-egg mug recipes! I have loved cooking and baking since I was 7, but I’ve become disabled and live alone. These recipes are a wonderful gift! Don’t need a whole cake, and there’s a finite amount of space in the freezer, ya know!?

    Anyway, I’ve just shared several of your recipes with my mom. She’s very grateful, and may have signed up for your newsletters also!

    I have a question for you, has anyone come up with savory (soups, stews, mini-teensy casseroles) mug recipes? I’ve been trying to figure it out as I go, but that would be a huge hit with singles, seniors, etc. Just a thought. I’d certainly buy that book!!

    1. Hi Valori! I'm so glad that you're excited about my mug cake recipes! I'm sorry that I don't have any savory, dinner-type mug recipes, but you're right...that would be a great idea! I do know of a blog called "Dessert for Two" where Christina shares sweet and savory recipes made in small batches. She has cookbooks as well following the same theme. Hope that helps! 🙂

  11. I made the regular version. It was good but next time I will mix the dry ingredients first because it had a slight baking powder taste. Thanks for the easy recipe!

    My blueberries went bad, so I replaced them with mini chocolate chips, it tasted perfect. It rose a little more than expected, but as it chilled it settled to a normal state. Overall, it was an amazing breakfast!

  13. If you don't have blueberries or they're out of season, or if you simply don't like fresh blueberries, I substituted a big spoonful of blueberry jam and it was amazing... after I let it cool down. I assume this would work with other flavors of jam as well; I just swirled the jam in and it was very good.
    Also, this really does take quite a while to cook; it was slightly underbaked at a minute and a half over my usual mug cake cooking time, which is 90 seconds. Microwave wattage will vary, yadda yadda.
    Anyways, this isn't bad, though next time I'll cook it more and add the sugar garnish on after baking- it kind of melted into the jam.

    I made a vegan version for this! It was so good! I substituted almond milk and vegan butter. I microwaved it for 1:15/checked/15 more sec and perfect!!

    1. Thanks for sharing, Haley...I happy to hear that your vegan version turned out well and I'm sure your tips will be helpful to others! 🙂
