A Cup of Coffee Cake (in Under Five Minutes)

I don’t love chocolate. BLASPHEMY I KNOW! It just doesn’t do it for me, what can I say? I do, however, love me some cinammon. And some crumbles. And some crumb-topping, if you will. Can I get a what what? Is anyone with me?

But okay, I don’t always feel like making a giant coffee cake and eating it for three days straight until it’s gone. No, wait, that’s a lie. I do want to do that, but it’s really for the best if I can just make a single-serve coffee cake. Reduces temptation, right?

So I messed around with ingredients, a measuring spoon, and a microwave, to see if I could create a crumbly, cinnamony coffee cake in a cup that could be made in a microwave in about five minutes at 11 p.m. while i watched The Notebook for the 5,000th time (hey girl, don’t even try to pretend you don’t love Ryan Gosling, I won’t hear it). I think I’ve come up with a decent substitute for coffee cake, considering the small amount of time and effort that goes into it. Give it a try and tell me if you disagree.  But again, don’t try to disagree with me about Ryan Gosling.

How to Make Five Minute Microwave Coffee Cake in a Coffee Cup

Well, first you’ll need a cup. If you want it to puff up over the top of the cup, use a small one. Or if you want to dig into the cup, use a big one. It matters not.

Add a tablespoon of butter.

Soften it in the microwave for 10-15 seconds. Don’t melt, just soften.

Stir in 2 tablespoons of sugar until it’s fluffy and creamy, maybe 30 seconds.

Now you can add some egg. you don’t have to, but without egg it’s more crumbly and less cake-y. You can do a whole egg, but I like to break the egg into a ramekin and stir it up, then split it between two cups of coffee cake, or just use half for one coffee cake. But really, play it by ear. Try it out and see what tastes best to you.

Then stir in 2 tablespoons of sour cream and a few drops of vanilla. We’re talking droplets here, don’t add too much.

Stir in 1/4 cup of flour and 1/8 teaspoon baking powder.

If you want some crumb topping (you know you do), in a separate ramekin or bowl add 1 tablespoon butter, 2 tablespoons flour, 1 tablespoon of brown sugar, and 1 teaspoon of cinnamon.

Smoosh it together with your fingers for a few.

Now back to your cup. Your ingredients are all mixed up, so…

Add the crumb topping mixture to the cup…

Then microwave it. Start with 1 minute, then do 10 seconds more until it’s done to your liking. For my microwave, a minute 20 seconds does it perfectly.

It will be REALLY HOT when you take it out of the microwave.

Let it cool down for a few seconds, then dig in.

This is basically a start for a quick microwave coffee cake in a cup recipe, you can adjust to your own tastes and liking, since this is a serving for one after all. I like it just like this, but my husband doesn’t mind it without the egg. You may want more of this or less of that to suit your tastes. I look forward to hearing any adjustments you make and finding out if cake in a cup seems worth it to you. Ok, now i’m hungry, off to find my measuring spoon and a clean cup.

Am i missing something here? Where is the coffee in the so called coffee cake in a cup? x


I think it’s known pretty much everywhere that coffee cake is a cake that you eat with coffee. Pretty much any recipe of regular cinnamon coffee cake contains no actual coffee. It’s a morning/brunch kind of food.


hello i just calculated the calories (at least with the brands i used) and i found it to be about 550 calories.


Used 1/2 and egg and followed directions perfectly. The end result was a cup of gummy consistency mess.


You are microwaving it for too long. When it comes to these cakes, Less is more.


I used a whole egg, and microwaved it for about 1 min 45 sec. Turned out into a fluffy cake.


This was good at the top, but when I got to the bottom and it was just the plain cake it did not taste good, very odd tasting. So if I do this again I will probably blend in the topping with the batter and maybe do applesauce instead of the sour cream


When it comes out of the microwave nix other a bit and make sure the cinnamon crumble parts are even throughout the cup and I found adding like a teaspoon of milk after mixing it and then remaining it helped

I made this recipe for dessert tonight…and it is as easy as promised, though as a first time maker of this recipe, it took a few minutes more than 5 to do the whole thing (but not much more). I followed the recipe exactly while guessing on measuring, and used almost an entire egg. I did have a medium size mug and it expanded so much while cooking that half of the topping spilled out onto the plate. It was seriously sticking out the top almost as tall as the mug, but then immediately deflated as soon as the microwave stopped. I cooked it for 1 min 10 seconds and the flavor was very good…though the texture reminded me of a sponge cake (not my favorite type of cake). Maybe I cooked it too long…or should have used a small bowl since I don’t have massive mugs. Regardless, I loved being able to make a single serving dessert like this. Thanks for sharing!


how do you make it fluffier and not so dense? I added about 3/4 of an egg. should I have put less egg in or could it be because my butter and sugar was to liquidy.


Good quick easy coffee cake for one! The first time I made it I used salted sweet cream butter – the second was unsalted. Better with a pinch of salt for sure – makes for more complex flavor!


mine was nothing to write about gummy mess…used egg and sour cream no cake like texture here!


Oh my goodness, thank you, Jaime! I had tried a coffee cake mug cake previously, but that recipe called for twice the sugar, a whole egg, 2 tbsp. of oil instead of 1 tbsp. of butter, and various other small differences, but it turned out to be inedible and I have eaten some pretty awful stuff! This recipe turned out to be heavenly. As mentioned in some other comments, if you want crumbles all the way through, you have to save some or stir them in (pretty self-evident, I thought) but the cake was delightful! I cooked mine for 1 min., 20 sec., and it rose nicely, and was not at all gummy, which was what I was nervous about, since that was how my previous attempt at mug coffee cake had ended up. My only problem: you use half an egg, and what am I going to do with half an egg? make another coffee cake mug cake, of course! My mouth says thank you, my hips say, “How am I supposed to slim down with all of this coffee cake around?” 😉 Thanks again!


Ha Ha! Love this comment. Thank you for leaving it and so glad you enjoyed your coffee cake! My hips apologize to your hips.


Very good. A lot of sugar. I think next time I will halve the sugar for the crumb topping. I also used yogurt instead of sour cream because I had no sour cream. Great treat for one.


I think that i will half the entire crumb topping because it was a little too much for my liking. Other than that, great recipe though.


I added blueberries, and it was amazing! Thanks for making this pregnant woman’s day!

It would be so awesome if this recipe were written traditionally so that when I print it I’m not blowing through lots of paper and color toner. I did it, but still~

When posting microwave recipes, it is very helpful if you indicate the wattage of the microwave you used so those of us with more or less powerful ones can adjust accordingly. Thanks!

Sub egg white only, Truvia half strength and gluten free flour. 1 min. Yummy. Topped only with cinnamon and dark chocolate raisins.


I love love love this recipe with and with out eggs. I didn’t have sour cream and I used coconut blended green yogurt and it gave it a nice nutty flavor. Just thought I share. But over all the best coffe cake recipe and the most moist cake in a mug recipe! Yummy!

If you don’t mind me asking but why sour cream. My mother looking for mug coffe cake and I show her this. She didn’t like it and it didn’t make sense why sour cream. I make coffe mug once and never have I ever put sour cream in it.


This cake was really good, I did have to make some changes, such as I used tropical flavored yogurt instead of sour cream. I think I cooked it a bit to long because it was slightly spongey,but not like spongecake. Anyway it still tasted really nice.


MY ABSOLUTE FAVORITE THING EVER!!! I normally don’t like cake mug recipes but i love love love LOVE this one, i don’t add any egg and i find it to be the most amazing thing ever!
