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.

    Just finished eating this. It was delicious!! I thought I would still crave something sweet after I ate it but it was super rich and tasted amazing. I used one tsp of veg. Oil and one tsp of apple sauce. I will definatlety be adding this to my regular go-to-recipes!

    I had to readjust this recipe because of what I had on hand and also some food allergies, so I ended up winging it. I used 1 1/2 T of maple syrup instead of xylitol, and I used 1 1/2 T of almond butter, I believe. I also halved the coconut oil and the milk (I used almond milk). I also poured in a bit of coconut flour (perhaps 1 1/2 T). It came up more like a goop than a cake, but it was quite good. It was a bit too rich, so I would perhaps use a little less syrup next time, but my husband and I thought it was delicious. Thanks for some great inspiration! 🙂

    I just made this because I had a chocolate craving and didn’t want to spend too much time baking b/c of an exam tomorrow! OMG THIS IS AMAZING! THANK YOU!

  4. Beth says:

    Katie, if I dont have powder could I use reg nut butter?

  5. Caroline says:

    This is sooooooo delicious!!! I make it all the time!! wish I knew of an almond butter version of PB2 that would be so good!!! 😀

  6. Deanna says:

    I made this with almond meal instead of pb2 (which I’d never heard of)! I also added more cocoa powder and Splenda tham called for.

    It took longer to cook – about 2.5 minutes, but otherwise turned out fine. I topped it with raspberry jam, for some ersatz Black Forest cake!

  7. Teri says:

    I tried this tonight & it was fantastic. I was so tempted to only eat the batter after licking my fork but I’m glad I didn’t. 🙂

    Okay so I’m a little late but oh my gosh Katie, I just made this and it was DELISH! I used chocolate PB2 and topped it with some PB and jelly! Mmmm! Also subbed mashed banana for the oil and it was still great. Keep up the awesome work, I love your recipes!

    1. Rihanna says:

      The cake was also a really nice size, I wasn’t expecting anything that big for so few calories!

  9. Charlotte says:

    Amazing! I still had a little bit of PB2 left in the jar and I had no idea what to do with it…such a great way to finish it off :]

  10. Rhonda says:

    Hmm? Where to get powdered pub? Not heard of that.

    This is AMAZING! I’m addicted.

    We put it in the toaster oven (we don’t have a microwave) at 375-ish for 40 minutes with great results.

    Thank you for your incredible recipes!

    I make this using unsweetened coconut milk, applesauce, and add half Netressa (Made with Monk Fruit) and half Stevia. The calorie count for my version is 84.86 cals. Or just 85 calories.

  16. Michelle H says:

    As other have stated: “RUN, don’t walk, to your kitchens now”!!!! OMG, you have done it yet again!!! I just made this cake with modifications: used the mashed banana instead of coconut oil, and used 1 packet of nunatural stevia, and I came out PERFECT, and I mean PERFECT. Moist, yummy, and crunched the numbers, only 100 cals per serving, and best of all: GLUTEN free, Sugar free!!! Thank you SOOOO much again, you are my hero. Can’t wait for the book
