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.

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.

    Can’t wait to try this! Although I should probably wait to work off my turkey from us in Canada’s thanks giving yesterday!

  2. Laura M says:

    I always love the chocolate-pb combo. Definitely one of my favorite flavors of all time. Keep up the good work! And I was always friends with the boys too, because they always wanted to run around outside like I did!

  3. Sophie says:

    Do you think I could make this with a hit of normal pb if I don’t have any pb flour? And maybe just add normal flour to give it a similar consistency? I really want it now 🙂

    1. Chocolate-Covered Katie says:

      I *think* you could make the original recipe (linked in the post where it says “inspired by this recipe”) and add some pb to it…

    2. Alanna says:

      I would guess you might have luck subbing regular flour for the PB2 and subbing peanut butter for some (or all?) of the oil… seems like the PB stands in for oil when doing the choc PB boatmeal. If you figure it out, let us know — I’d definitely be interested to try it!

      1. Kristin says:

        This is what I did just now because I had to have this as a snack and had never heard of PB Flour before this post!

        I used “regular” unbleached flour, took out the oil and subbed in 2 tsp crunchy natural peanut butter. worked like a charm. The crunchy peanut butter has the added bonus of adding texture! (Probably not as “healthy” though…heh)

        1. Alanna says:

          Yummy — thanks for letting us know, Kristin!

        2. HealthFoodJunky says:

          That is so helpful!

  4. Emma says:

    Katie, I just made this and then I had to run to my computer to tell you how AWESOME it was!!! Seriously even better than the regular flour version.

    I am in love with this cake! 🙂 🙂 🙂

    People, RUN to your kitchens and make this. You won’t be sorry!

  5. Katie @ Peace Love & Oats says:

    I love making cakes in mugs! Haha I’m so lazy with the microwave! And I didn’t think boys had cooties, I remember sending a love note to a boy in Kindergarten. Sadly he sent me an I Hate You note back… I guess he thought girls had cooties. Good thing he turned out to be a nice guy eventually.

  6. kim@hungryhealthygirl says:

    Would it be so bad if I had this for breakfast tomorrow morning?!?!?! Yum!

  7. T says:

    This looks marvelous… I have such a sweet tooth lately, but sometimes its good just to have enough for one.

  8. Aja says:

    I must make this!
    Most of my friends were boys. I got along with them better for some reason.

  9. Greta says:

    Oh, are we just assuming that every woman is straight now?

    1. Chocolate-Covered Katie says:

      No, I’m not sure why you would think I implied that :(.
      Never meant to imply that… in fact, I almost didn’t post the question at all because I worried that any male readers might be annoyed I was assuming all my readers were girls! But I finally decided they could easily answer the question too if they wanted! 🙂

      1. tiffany says:

        I think she might be meaning the post and not the question. You joked saying to leave your boyfriend so they don’t make you share. I think Greta would prefer if it had said “leave your boyfriend/girlfriend…” I personally think this is ridiculous though. I’m all for equal rights and all that, but picking apart everything that doesn’t include the use of “his/her” “boyfriend/girlfriend” every time is absurd.

        I think having to worry about making every sentence “PC” is insane. If Katie had said something discriminating i could understand being bothered, but do you really expect people to say girls/boys his/her girlfriend/boyfriend every time one of those words might be used? Should she also not call these “single lady” recipes because the person might not be single, or because maybe it’s a man making the recipe? Where do you draw the line?

    2. Alanna says:

      My goodness, hypersensitive much? I’m sure Katie didn’t mean anything by it, so no need to get defensive about a statement that was likely said in all innocence. You could choose to take it as meaning two girlfriends would be more likely to share than a girlfriend/boyfriend. 😉

  10. Samantha says:

    I love my single lady recipes. And this one was made for me. Having tried both PB2 and Betty Lou’s for some reason I think Betty Lou’s is better (although my experience with baking is it doesn’t matter much). I have had great luck subbing them in the microwave creations. I can’t wait to try this. 🙂

    And that frosting…how did I miss that?

  11. Ashley @ My Food 'N' Fitness Diaries says:

    Um yes, you better believe this will be my dessert tonight! Can’t go wrong with the PB + chocolate combo! 😉

  12. Andrea says:

    Mmmm, I’ll have to track down some PB2!

    I was friends with boys growing up because all of my parents’ friends had boys. We got along well, I was just never too thrilled about their favorite activity of searching for toads in the swamp. I did love the four-wheeler ride to the swamp, though! It’s funny because at school most of my friends were girls, and we did still give each other cootie shots. Haha!

  13. Karen says:

    This was my afternoon snack, topped off with some of your voluminous ice cream (made with canned coconut milk). My oh my was it good! Your recipes are the best!

  14. Kristen @ notsodomesticated says:

    I was friends with boys when I was little. Then starting in 2nd grade, I had crushes on boys haha. I skipped over the “cootie” phase! 😉

  15. the 3volution of j3nn says:

    I’ve always gotten along with boys, probably better than girls due to me having “boy” interests; video games, cars, guns!, etc. 🙂

    Peanut butter and chocolate is never a bad idea! I have some powdered PB, not flour, that should work.

  16. Annie says:

    Oh gosh, the recipe got me, of course, and then I see that folks ran immediately into their kitchens to make it – – and now I feel as if I must do the same! I have mugs! Lots of mugs! I want to fill them ALL up with this stuff ;-)!
