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.

  3. Kathleen says:

    Can you substitute peanut butter for the powdered peanut butter? What else would you have to change?

  4. Allie says:

    Katie just wanted to say thanks. I love this.

  5. Vicky says:

    Looks so yummy! I love to short ingredients list.

  6. Sarah A says:

    Would it be possible to make this without chocolate so it’s just a peanut butter mug cake? Would I have to substitute something for the cocoa powder?

    Hi! I’m really interested in this recipe, but I think there’s an error with your nutritional information. I’m a diabetic on a low sodium diet, so I always double check all nutritional information for recipes I’m interested in when I enter it into MasterCook. This is what MasterCook calculates from your posted recipe:

    Per Serving (excluding unknown items): 215 Calories; 8g Fat (29.4% calories from fat); 20g Protein; 23g Carbohydrate; 8g Dietary Fiber; 6mg Cholesterol; 625mg Sodium. Exchanges: 0 Grain(Starch); 0 Lean Meat; 0 Non-Fat Milk; 3 1/2 Fat; 0 Other Carbohydrates.

    I double checked all the ingredient entries in the program, and they are correct. Did you forget to enter something for your nutrition info, or is MasterCook really messed up?

    1. Lisa Hartjes says:

      I should note that the nutrition info link goes to “Microwave Peanut Butter Cake”, and not a chocolate peanut butter mug cake recipe.

    I love your recipes!! I just started sharing them with my daugther to ise in her easy bake oven!!

    I didn’t have PB powder, so I used a tablespoon of regular PB and 2 tablespoons of oat flour. I cooked it in the microwave for 45 seconds and topped with a dollop of Greek yogurt sweetened with a little Splenda. It was so moist and delicious….definitely satisfied my craving for chocolate and PB….oh yeah, I added a few chocolate chips too 😉

    This cake tasted AMAZING! All I had was chocolate powdered peanutbutter from PB &Co, so I left out the cocoa and put in 5 tbsp of that ( because I thought the batter looked a little runny.)didn’t have any oil so I used mashed banana.( I hate the taste of banana and chocolate, thanks to “healthy” banana brownies. There is no way you could taste the banana, I should know, I am very sensitive taste-wise.)I also added a tsp of real pb, cuz why not? Used real sugar because that was all I had on hand . Next time I think i will cut out the white sugar and use honey,for refined sugar free, but decrease the milk(does anybody know if that should work?) ? 5 Stars!! Great job Katie keep it up!
