I don’t love chocolate or chocolate chips. 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? Who is craving a microwave oven coffee cake? A coffee cake mug cake is where it’s at.

So, 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 microwave coffee cake. Reduces temptation, right? It’s just one of our single-serving dessert in a cup microwave dessert recipes.
Microwave Coffee Cake
So I messed around with ingredients, a measuring spoon, and a microwave, to see if I could create a crumbly, cinnamony mug coffee cake 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.

How to Make Five Minute Microwave Coffee Cake 

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.

Making Mug Coffee CakeIf 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.

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

microwave coffee cake recipeThis is basically a start for a quick microwave coffee cake in a mug 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, however 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.

Maybe experiment with adding coconut, peanut butter, sprinkles or even cocoa powder to spoor cake batter for a chocolate mug cake, if the inspiration strikes. You could also top it with fresh berries, pecans, or maybe a scoop of vanilla ice cream. Ok, now i’m hungry, off to find my measuring spoon and a clean cup.
