Five Minute Microwave Coffee Cake in a Coffee Cup

"This is a genius idea, especially for those "On The Go" or those that only want one serving at a time. They are also great for singles who don't like having a lot of sweets sitting around the house and it gives you variety for your breakfast menu too, not to mention how delicious they are! I found this on the Prudent Baby blog, and thought I would share it here after trying it first myself. I loved it! SUBSTITUTION IDEAS: You can substitute coconut oil instead of butter, whole wheat or spelt flour, half and half, cream, yogurt (regular or Greek) instead of sour cream, and only 1 tablespoon of sugar, or use a sugar substitute or honey in place of the sugar."

Step 1

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.

Step 2

Coffeecake: Add butter to the cup. Soften it in the microwave for 10-15 seconds. Don’t melt, just soften.

Step 3

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

Step 4

Break the egg into a ramekin and stir it up, then split it between two cups of coffee cake, or just use half of the egg mixture for one coffee cake. (you can add egg. You don’t have to, but without egg it’s more crumbly and less cake-y. You can do a whole egg to one serving if you want to. Play it by ear. Try it out and see what tastes best to you).

Step 5

Stir in sour cream and vanilla.

Step 6

Stir in flour and baking powder.

Step 7

Topping: In a separate ramekin or bowl add butter, flour, brown sugar, and cinnamon. Smoosh it together with your fingers.

Step 8

Add the crumb topping mixture to the cup.

Step 9

Microwave for 1 minute, then do in 10 second intervals until it is done to your liking. (In my microwave 20 seconds works well).

Step 10

It will be REALLY HOT when you take it out of the microwave, so let it cool down for a minute before digging in.

Love the convenience of making this on my way out the door to go to work. I grab my mug and go, eating it as soon as I get to work. Delicious, filling and so easy to make!

WOW! I have tried many microwave mug cakes and I was delighted with this one! After the first one I made which ended in a disaster in the microwave, I have always used a 16 ounce mug. I'd rather the cake to be low in the cup than bubbling out all over. Plus it allows for more room for ice cream. This recipe is an easy and tasty treat. Another thing I like about these mug cakes is its a single serving and for those who have little or no will power, it keeps DH from eating second helpings of a whole coffee cake. Thanks for posting! Made for Billboard tag.

Since this is easy and fast to make in the microwave I have made this a few times now and we love it for a sweet snack. We like it hot from the oven with whip cream or ice cream on top. Yum yum!

Wowzers! This actually works! It turned out as a delicious fluffy coffeecake with a streusal topping that I loved! I thought it would be rubbery, but it wasn't. I doubled the recipe in two 16oz containers. I wouldn't recommend trying this in anthing less than a 12oz container because it may overflow like it did with my Mom in a regular sized mug. I followed the recipe exactly, except for adding some nutmeg to the batter and cooking it a little longer in my 1200 watt microwave. Next time I think I'll add some lemon zest to the batter too. Thanks for posting this wonderful recipe Linda! I'm so happy to have found it since my oven is broken. Freddy Cat says thanks for the cake! Made for the Billboard recipe tag game.
