What’s your middle name? Mine is Overindulgence. Well, it should be anyway.

Really, it’s Frances. Which was my grandma’s name. Dorothy was my Nana’s name. I love my names…now. Going through childhood as an overweight kid with buck teeth and the name Dorothy Frances was, well, hard. Dorky Blubber was my nickname, a play on my maiden name.

Overindulgence has always been my problem, obvi.

Which is why mug cakes and single-serve desserts and my favorite things everrrrr.

Recently I really, realllllllly wanted coffee cake. I almost made a whole cake, but the realization that I would eat an entire cake (one slice at a time) stopped me. That’s when a mug coffee cake jumped out at me.

I’m pretty good at math (I should be, since I majored in it in college). My love of all things math has made it easy for me to figure out how to cut down my favorite recipes to single size. I’m good at fractions,what can I say?

I started with my Mom’s Coffee Cake Recipe, which I’ve previously made into Carrot Cake Coffee Cake, Coffee Cake Pie and Funfetti Coffee Cake. The base of the cake are the usual suspects: oil, sugar, flour, egg, cinnamon. 99% of these are really easy to cut down to one serving. The only one that is hard to do is the egg. So I left it out, and I didn’t miss it at all!

FYI, when you’re twelfing (is that even a word?) a recipe, you need to know the cup to tablespoon to teaspoon conversions. I’ve made you a handy-dandy chart, in case you’re interested. I have a few that I’ve pulled from magazines and cookbooks over the years taped to my fridge. It makes it an easy way to reference the numbers, when you need it.

I made you a printable. Print it out on cardstock and marry it to your fridge. You’ll be happy!

This single-serve mug coffee cake tastes just like the original, but is enough to satisfy that coffee cake craving without the need to shop for bigger pants.

Unless, of course, you’re me. And make it Every. Single. Day.

What can I say? Overindulgence is my middle name.

A Single Serve Mug Coffee Cake is the best way to indulge in a sweet breakfast without killing your diet!

How to make a Mug Coffee Cake

  1. You can use a small ramekin, like I did, or a mug. It won’t completely fill up a mug so the pictures look better in a ramekin.
  2. Be sure to spray it with nonstick cooking spray. I also recommend rinsing the dish before it cools (holy stuck on food, batman).
  3. Feel free to reduce the sugar (even omit the brown sugar on top) to cut the calories.
  4. Add nuts for a nice crunch!
  5. You can use any kind of milk (regular, nonfat, almond, etc.)

  1. I don’t know how I haven’t reviewed this recipe yet! This is one of my tried and true recipes for when I need something sweet and I don’t want to put in a lot of effort. I found this recipe in !!!2017!!! when I was pregnant with my second child and I was obsessed. It’s been 6 years now and I just made another one and loved every bit of it. The recipe is perfect if you just follow the simple directions. I always double the recipe because my middle name is also overindulgence 😉 thank you as always for the amazing recipes, Dorothy!

  2. Definitely a small portion but I was trying not to overindulge so I thought it was the right size. It was moist and cake like. I might make it more of a streusel topping with a tiny bit of butter and flour added to the sugar and cinnamon. It was a good, quick mug cake.

  3. YOU! YES YOU! YOU NEED TO TRY THIS RIGHT THIS INSTANT! Seriously though, this was the best mug cake ever. The only thing is probably double the recipe, because the one serving is tiny. But this is wayyyy too good to exist… ✨✨✨😃 ITS SO GOOD (especially if you add extra topping in the middle… but shh)

  4. I found this to be a tad too salty. Otherwise good! Next time I will double the recipe except the salt.. Mix the cinnamon and sugar with butter and add in layers in the mug. And yes, there will be a next time.

  5. This was amazing! I used coconut oil and I added nuts to the topping. I wasn’t sure if the topping would be enough but once I put it in the ramekin, I discovered it was plenty! This is perfect with a cup of coffee first thing in the morning. I will definitely be making it again!

  6. Followed the instructions, ended up with a 1/4 coffee mug of nothing that looked like cake. I spread it on a small plate squashed it with a spoon and made little cookies out if the creation. Cake?

    1. It’s definitely not a traditional coffee cake but it should have at least gotten fluffy like cake. Did you make any substitutions?
