  1. Hello!

    I’m wondering what oven temperature you would cook this cake at and for how long? I don’t use microwaves at all but would love to try this!

    Thanks so much!

      I haven’t tried making this in the oven, but I would guess it would bake at 350 for ~30 minutes? Or just until the surface is firm and springs back when tapped. I hope you like the recipe!

  2. Wow–I love the looks of this recipe!! Do you think all the flour used could be peanut flour? I’m not used to baking with peanut flour much, so I’m not sure how it might change things. 🙂

    • dessertswithbenefits

      Peanut flour tends to make things really dense and rubbery, so I would recommend keeping the oat flour in there. Plus, the oats and peanut butter create a complete protein, while peanuts alone are an incomplete protein 🙂

  3. Ahhh the perfect use for bananas!

  4. This looks delicious! Your microwave cakes make the best breakfasts! I can’t get enough of them, so it will be great to try a new recipe. I haven’t been able to find peanut flour anywhere, but I do have some PB2 powdered peanut butter. Is that the same thing? I hope it will work because I really want this for breakfast tomorrow.

      PB2 is similar to peanut flour, it just has a couple more ingredients while peanut flour is made from 100% peanuts. I haven’t tried this with PB2 but hopefully it works! 🙂

  5. Hello,

    This sounds amazing. Banana’s and PB are two of my favorite foods. Unfortunately, I just found out I have an allergy to Banana’s. 🙁 Is there something I can substitute for the banana in this recipe?

    Love your Blog!!

  6. Oh wow, a microwave cake with all the goodness of PB and bananas? I would definitely try!!

  7. This looks amazing. Bananas are one of my favorite foods ever. I can’t wait to try these.

  8. What a great recipe! It looks so yummy!!


  9. I love your single-serving recipes. I just made this and it was very good. It reminded me of banana bread.

  13. Looks great! Can I replace peanut butter flour with Powered peanut butter or PB2…if so would amount be the same? Thanks

    • Thanks so much Debbie! I haven’t tried this recipe using PB2 but you can give it a shot!
      PB2 already has sugar and salt in it, so you should reduce the Truvia to 1 packet and reduce the salt to 1/16 tsp or omit it completely 🙂
      I hope this substitution works out okay, enjoy!!

  14. How much honey can I replace for the truvia?
