Healthy Single-Serving Chocolate Peanut Butter Microwave Cake

Single-Serving Chocolate Peanut Butter Microwave Cake
Remember that Peanut Butter Microwave Cake (with a delicious PB Frosting!) from wayyy back last April?  Well, that recipe just got even better because now chocolate is in the picture!  This healthy single-serving Chocolate Peanut Butter Microwave Cake is packed full of chocolate and peanut butter flavor, but without all the sugar, butter and oil you might expect from such a tasty dessert breakfast.  You’d never know this super easy five-minute cake is secretly healthy  😉

^^ See how moist it is?
This cake is sugar free, gluten free, high fiber, high protein, eggless and vegan.  Now I’ve gotta admit, that sounds kinda gross and off-putting…  like the words you’d use to describe a stick of celery…  but trust me, this cake is 100% delicious, mouthwatering and addictive.
Chocolatey, peanut buttery, sweet, moist and filling — that certainly sounds like a decadent cake rather than something nutritious, right?  Well this breakfast cake has the best of both worlds…  it’s a dessert with benefits!  Just like the logo of this blog  🙂

  1. You must be reading my mind! I’m on a microwave cake spree from your website. Yesterday, I made the peanut butter microwave cake with the frosting for my BF and I and. All day long we kept reminiscing how delicious breakfast was. I just finished the last crumbs of the chocolate buckwheat cake. And now I see this recipe? Squeee!

  2. What is the little cocotte with handle you are making it in? I would love to get one to try it too (if you have a link to it on a site or amazon that would be great!)…I just have ramekins and this would make it so much easier to make this. Thanks!

    • Penelope-
      I’m sorry, I have no idea where they are from (they belong to my mom, and I recall her having them for over a decade)!!
      However, they look pretty simple, cheap and easy to find. I’m sure they’re on Amazon, at Crate & Barrel, Williams Sonoma or Sur La Table (aka, the best stores EVER!)
      Hope you like the cake 🙂

  3. Hi Jessica! Is there anything I could use instead of Truvia? For example agave or honey?

    • Nadja-
      You can omit the Truvia in the cake if you like and simply top the baked cake with a drizzle of honey, pure maple syrup or agave. If you think you need some extra sweetness, just add some fruit on top too (diced strawberries and sliced bananas are delicious)!!

  5. Nadja-
    What a great idea with agave – super yummy! I would be curious how that would taste against the chocolate and peanut butter!

  6. this looks great but i don’t use a microwave… is there toaster oven or oven suggestions?

  7. I have noticed that many of your recipes use almond milk. I am allergic to almonds. Which would you suggest as a substitute, rice milk or coconut milk?

  10. Jess, this looks divine! I don’t want to buy peanut flour though because I suspect I wouldn’t use it for anything else. Could one substitute Peanut Butter? Thanks

    • Olivia-
      I thought the same exact thing when I bought my first bag of peanut flour! But six bags later, I have found so many new ways to use it. Unlike PB2, peanut flour isn’t sweetened so you can use it in savory applications too (it makes a reeeally good Asian peanut sauce). Oh, and I probably used an entire bag for peanut butter icing purposes only 😉
      The only “downside” to peanut flour is that it has a very unique texture in baked goods, so it’s hard to substitute. It’s really absorbent, similar to coconut flour and oat flour. I’m not sure if peanut butter can replace the peanut flour here, but you can definitely give it a shot.
      I would recommend mixing 2 tbs of natural peanut butter with the wet ingredients, and increasing the oat flour to 1/4 cup. The “baking” time might also need to be adjusted but I’m not exactly sure how much.
      I hope this helps, and I hope the cake turns out!!
