Chocolate Peanut Butter Cake in a Mug


This is the kind of recipe that will make you want to leave your boyfriend if you have one.

A "single-serving" chocolate cake that can be made in your microwave, tastes like a Reeses peanut butter cup, and is under 150 calories for the entire recipe: https://lett-trim.today/2012/10/08/chocolate-peanut-butter-cake-in-a-mug/

Or at least lock him outside for an hour. A girl needs her space when chocolate and peanut butter are involved.

No boys allowed.

Chocolate Peanut Butter Mug Cake

(single-serving)

Adapted from One-Minute Chocolate Mug Cake.

    • 1 tablespoon plus 2 tsp cocoa powder (8g)
    • 3 tablespoons powdered peanut butter (PB2 or Betty Lou’s) (For substitutions, see “nutrition facts” link below) (18g)
    • scant 1/16 tsp salt
    • 1 tsp sugar or xylitol (omit if you like bitter chocolate cake) (4g)
    • 1/4 tsp baking powder
    • pinch stevia OR 1 additional tablespoon sugar
    • 2 tsp coconut or veg oil, or mashed banana or applesauce (I personally don’t like the fat-free option and recommend the oil, but I’m adding the option because I know many of you don’t mind the taste/texture of the lower-fat version.) (8g)
    • 3 tablespoons milk of choice (45g)
    • 1/4 tsp pure vanilla extract

Mug Cake Recipe: Combine dry ingredients and mix very, very well. Add liquid, stir, then transfer to a little dish, 1-cup ramekin, or even a coffee mug. If using the microwave: cook 1 minute 25 seconds (time may vary, depending on your microwave’s wattage). If you don’t want to eat it straight out of the dish, be sure to spray your dish first (and then wait for the cake to cool before trying to remove it). You can cook this in an oven if you prefer, but you’ll have to experiment to find the correct amount of time.

Peanut Butter Cake

Were you friends with boys growing up? Or did you think boys had cooties?

When I was really little, I was friends with all the boys. They had better toys! Swords and transformers and legos beat playing House any day. I never even heard the idea boys had cooties until third grade, and by then I already knew that wasn’t true.

    I’ve been so expecting you to post a single-lady chocolate peanut butter cupcake/cake! Are you sure this is a chocolate-covered blog since you don’t have any chocolate single-lady recipes on the single-lady cupcakes -page? 😉 I’m sure this recipe will cure the deficit!

    I’m glad I don’t have any peanut butter in the fridge as I would be making this cake right now instead of writing this comment… But I DO have some cashews – homemade cashew butter and then making some chocolate cashew butter mug cake? Well, maybe after getting my school work done for the day…

    1. Pipsa says:

      I made this cake today – so delicious! I didn’t have peanut butter powder (unfortunately it isn’t sold here in Finland, where people don’t know the good stuff… here peanut butter isn’t anywhere near as popular as it is in the States) so I substituted for 2 tbs of self-powderized cashews and 1 tbs of oat flour. Worked fine! I made this very intensively chocolatey and bitter, as the cake was pitch black 😀 But as I said, the most delicious mug cake I have eaten so far, so thanks so much Katie for a great recipe! I also have to mention that I made your black bean brownies in the weekend for my friends and they (and I!) adored them. They are the ultimate black bean brownies, but as well the best brownies ever, healthy or not!

    Perrrrfect timing on this recipe! I just got pb2 and I’ve yet to use it for anything except making peanut butter. I’m so excited to try this!

  3. Megan Wood (@IRun4Wine) says:

    Hi Katie! I am so glad I came across your site. Your blog is amazing!

  4. Justine says:

    This isn’t a question specific to this recipe, but where do you buy your stevia?

    1. Chocolate-Covered Katie says:

      Whole Foods or NuNaturals.com

  5. Linde says:

    Hey Katie did you dye your hair?

    1. Chocolate-Covered Katie says:

      Nope! I was using John Frieda blonde shampoo and spray this summer, but I decided I didn’t really like it, so my hair’s slowly going back to its normal color now :).

      1. Linde says:

        I think it looks really good on you! Love your new logo, and your newest recipes!

  6. Tama@Tootlee says:

    Katie! WHAT HAPPENED TO YOUR LOGO!?!?!?!?!?! On my computer I can still see half of the old one, but your new one is kinda half-on-top of it. But what happened to your hair? Did you dye it?

    BTW, your new logo–what I can see of it–looks really nice!

    1. Tama@Tootlee says:

      Huh? I can’t even see the new one now! Oh well.

      1. Chocolate-Covered Katie says:

        You caught me mid-change ;).

        Can you see it now?

        1. Tama@Tootlee says:

          Yup, and it looks nice!

  7. Marie2375 says:

    I’ve bought peanut flour at Trader Joe’s.

  8. Samantha says:

    Cuteness on your new header! Maybe it has been up there a bit but I just noticed it.

  9. Danica @ It's Progression says:

    I “mmm”ed as soon as I read the title to this post! 🙂

    Personally, when I was at school, I mostly had guy-friends. I always found it hard to fit in with the girls – never being a girly-makeup-wearing-boy-seeking girl myself 😉 but now I have a small mixture of both as friends, but tend to keep to myself as I’m quite shy..

    This recipe looks and sounds so good, and I know just the person who will LOVE it – might have to add some white chocolate chips.. 😛

  11. Ashley @ Wishes and Dishes says:

    Boys definitely had cooties in my world – no interest at all when I was growing up. Haha. This looks delish!

  12. Jennifer @ Peanut Butter and Peppers says:

    O.M.G! I know what I am having for dessert tonight! I can’t wait to try this!! It sounds amazing!!!

  13. Alyssa says:

    I was more friends with girls growing up, but later in life I’ve found myself more akin to men. I seem to get along better with them 🙂

    Cake looks awesome! Not enough to share, that’s for sure!

  14. Laura says:

    I was friends with everyone, but my one best friend was a shy little boy. He’s timid, I’m outgoing, It was perfect! Just like this recipe! 😉

  15. kris says:

    KATIE!!!! You have outdone yourself with this one! I couldn’t wait to try the cooked cake so I tasted just the batter….tastes just like a peanut butter cup!!! YUM!!! Mine is in the oven baking right now…counting down the minutes until it is done!

    1. zosia says:

      how long did it take to bake it?

  16. Heather says:

    Oh my, I haven’t been on your site for a while, so when I saw the new banner– you’re blonde!!! Don’t get me wrong, it looks nice on you, but I think you are drop dead gorgeous with brown hair in the picture you have with the link to the “About Me” page, it just brings out your beautiful eyes so much more. So, if you get tired of the maintenance of dealing with roots, don’t fear that you will lose any beauty- not the case!
