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 was thrilled to find a mug cake that wasn’t monstrously large! Thank you for a recipe that is just the right size. It’s nice not having to try to cut a supposedly single-serve recipe in half.
    I use a gluten-free flour blend and a cup-for-cup sugar substitute. Sometimes I sprinkle chopped nuts on the top along with the sugar (substitute for me) and cinnamon.
    This recipe is quick to assemble and cook, thus giving almost instant gratification!

  2. It was good and satisfied my sweet tooth. I used a tablespoon of melted butter and just a splash of oil to amp up the flavor. The texture was perfect. Next time I will cut the white sugar in half. I will make this again. By the way, I was surprised by the comments thinking coffee was supposed to be in the ingredients. Your responses were very kind.😁

  3. I really enjoyed this cake! I doubled the recipe before ever reading the comments, as I find I usually prefer a larger serving than most mug recipes provide (I did not find the double portion to be any smaller than a double if any other mug recipe). This made for the perfect size for me. The only thing I wish I’d done differently was layer the cinnamon & brown sugar like one reviewer suggested.

    I also used gluten free cup for cup flour and it worked great! It has a typical mug cake texture and I found it delicious.

    Thanks for the great recipe!

    1. I apologize you didn’t enjoy it. This is definitely not a traditional cake texture because it’s made in the microwave; possibly that’s what you struggled with.

  4. Oh! i forgot to add, if your going to double, layer the batter and cinnamon sugar like you would in a normal coffee cake!

  5. Amazing! Just yes before you start ( and i know like everyone said this but) make sure you double the recipie… i got three small bites out of mine!

  6. It was delicious but,I would definitely like triple the recipe because I got maybe 4 bites out of it idk how that counts as a single serving.

  7. It was OK. Just very very small. If you are looking to make this recipe make sure you double everything. If you do not the serving is barely enough.

    Other than that it tasted pretty good!
