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.

    It’s so funny. I was friends with tons of boys growing up when I didn’t really care what they thought of me! Now, not so much… Haha. I should probably try and change that 🙂

  2. Emily says:

    I always had more guy friends than girl. They were just more fun to be around with; so carefree and just relaxed (well, relaxed in a sense of personality, not motives – you try and tell a hyperactive little boy to relax haha). That stayed true through middle school and even now in high school. Girls are too, well I won’t say that word that comes to my mind since it isn’t really PG. x)

    The cake is cute. Just curious, what are those lighter brown spots? The cake looks too small to have peanuts in it, and I know it obviously isn’t corn. ..Am I the only one who thinks it looks a bit like corn? ..No? Maybe I’ve got it on my mind since fresh corn off the cob season is coming to a very quick end LOL. Anyway, is that coloring just from the powdered peanut butter? I’ve never used/seen it before so that might be it. Thanks!

    1. Chocolate-Covered Katie says:

      I think it’s just the part of the peanut flour that didn’t get mixed up completely with the cocoa powder.

  3. Ali @ Peaches and Football says:

    I had a couple friends who were boys growing up. I remember a picture from my first grade birthday party – I had ONE boy there. Poor guy. 🙂 Since I grew up with 3 brothers and no sisters, I got used to having rough-and-tumble boys around. In fact, I often remember playing Barbies and Legos with my brothers. I’d build large chairs and tables for Barbie while they built ships and intricate buildings.

    For any fellow Canadians: I like to order peanut flour (Protein Plus peanut flour = the old Trader Joe’s stuff; they do sell PB2, though) off of lowcarbcanada.ca because they do a flat rate 8$ shipping–some American sites have the actual peanut flour or PB2 for cheaper but shipping ends up, like, 26$ 🙁

    Pertinent to the recipe itself: this looks delicious! Your photography has improved SO much in the past few years, Katie 🙂

      1. tiffany says:

        I found that site after i looked at amazon…amazon.com has a combo pack of regular pb2 and the chocolate kind for like 10 bucks, but on amazon.ca it’s about 50-60 which makes no sense at all to me since they’re the same size containers.

  5. Leslie says:

    You have NO idea how excited I am to see this recipe! Your chocolate cake in a mug is my stand-by dessert and as a peanut butter lover I can only imagine loving this one even more. And the best part is that I have all the ingredients. Would it be too early to make one of these babies right now? 😉

  6. Andie says:

    Yay! More single-serving recipes 😀 This looks great. As soon as I get home from vacation I’m making this! (My meat-eating family likes their desserts with eggs and milk…sigh.) As for the question of the day, I was friends with boys growing up, but I just moved to a new high school…so I don’t know too many people at the moment….:/

  7. Sarahishealthy says:

    You have the BEST blog!!!
    So excited for this recipe, and for your cookbook!

  8. Bailey @ Onederland or Bust! says:

    This looks great. I really need to start making some of these recipes!

  9. Healthy Dessert Lover says:

    Pinned! I make your 1 Minute Chocolate Cake on a weekly basis, it is so good! Thank you for finally doing something with pb2! So excited to try this!

  10. Lisa C. says:

    The food, the photos, the recipe… it all just looks so good! I check your blog every morning and it always makes me smile. 🙂

    I think I remember giving all my friends cootie shots when we were little. Boys were strange creatures to us! Oh fun times ;).

  11. Dixya @ Food, Pleasure and Health says:

    I totally aree that all girls need lone time with peanut butter and chocolate. While growing up, I had alot of guy friends and it never occurred to me about cooties..and still today I think guy friends are much cooler..

  12. Janae @ Bring-Joy says:

    I thought boys were dumb all the way through college. Then I met a few spectacular guys that changed my opinion, & then of course met my husband who I think is the greatest man on earth. I still think most guys are “guys,” but I do appreciate their generally more laid back approach to life. (& now I have two boys of my own–I love them!).

  13. Erica { EricaDHouse.com } says:

    Perfect timing! I just started making microwave peanut butter cookies and I’m totally addicted. Was looking for new recipes to try!!

  14. Kristin says:

    I can’t wait to get this, but I’d like to add the icing too! Is there a link to that?

    1. Emma says:

      It’s linked in the post.

      1. Kristin says:

        doh!! Thanks 🙂

  15. Erika says:

    I just tried this with almond flour….major miss. Turned into a pile of mush. So I made a single lady cupcake instead!

    1. Karen says:

      Me too… I’m trying it today with almond flour because that’s what I had on hand. I’ve put it back into the microwave a few times, but it keeps coming out with a layer of liquid on the top and it’s not getting done. (sigh)

      1. Karen says:

        Feel free to delete my post here (I don’t see a way for me to do so). I will have to try this out again sometime. I just realized that I used TBS instead of tsp with the coconut oil. I can’t give an honest answer if this would work with almond flour or not. OOPS!

        1. Monica says:

          Ha ha, I did the exact same thing. Major chocolate craving kept me from reading the recipe right. I just added a few more tablespoons of almond flour. It did not set up like the picture, but still tasted yummy!
