    My daughter made this for me for my birthday. So delicious! Just the right amount of peanut butter flavor. So moist. Love the chocolate chips addition because how can you have peanut butter without chocolate?! Thank you for another amazing recipe.

      The best! So glad you loved it!!

    This is a great option for someone looking for a slightly healthier cake. The peanut butter icing is to die for!!

    I was a bit skeptical of this cake, but it turned out to be AMAZING!!! The peanut butter frosting was incredible, and the cake was so moist! I made them in two 9in cake pans and it turned out great. Will be making this cake again!

    ohhh! Cake looks incredible, so Banana & Hazelnut is a deadly combo!

    I want to make a Paleo chocolate hazelnut Buttercream, Can I use hazelnut butter instead of peanut butter and add cocoa powder to the frosting? Will the frosting be stable? How much hazelnut butter and cocoa powder to add?

    • replied:

      It’s delicious! Hazelnut butter should work in the frosting in place of the peanut butter, but I’m not 100% sure how much cocoa powder you’ll want to swap in for some of the powdered sugar. I’d have to test it out first!

    Hi,
    I tried this recipe and I made a mistake with banans measurement, it didn’t have that banana flavor and texture
    3 very overripe medium bananas, mashed (1 ¼ cup mashed overripe banana), I used around 400g mashed banana
    Can you give the approx measurement in grams? Please, I really want to make this recipe

    • replied:

      Hi! I didn’t weigh the mashed banana for this recipe, but 3 medium ones should be plenty. I’d love a bit more info about the texture – was the cake overly dry? Or did it have a consistency like banana bread?

    I always use this as our birthday cake but my question is can I use this for cupcakes?

    • replied:

      Love that! And yes, absolutely!

    I tried this recipe, which turned out delicious, but can i increase mashed banana by 20g to increase banana flavor and subtitute oat flour for coconut flour?

    • replied:

      I wouldn’t recommend changing those ratios or ingredients – sorry! Increasing the banana will likely make the cake too moist, and I haven’t tested the cake with oat flour. If you try either, just be sure to add a bit of extra flour if you add extra banana.

    Hi,
    How Can I replace the coconut flour with oat flour?

    • replied:

      Hi! I haven’t tested it, so I can’t be sure how the texture will turn out.

  • says:

    Can I replace peanut butter with oil to get a neutral-flavored banana cake?

    • replied:

      I wouldn’t recommend it! The texture and flavor will be much different.

    The name of this recipe says it all – the cake is DAMN GOOD! I baked it as a single layer in a 9×13″ pan for 40 minutes and it came out perfectly. I wanted snack cake squares to pack in lunch boxes and for on-the-go after school snacks, I know I will be making this on repeat. Thank you for the delicious recipe!!

      Great idea! So happy you loved this one!

      So happy to hear that!

  • says:

    Hi! I am just checking to see if this recipe will work as a cupcake?

    • replied:

      Yes, it should! Check them around 15 minutes.

    This is so good! The cake is delicious, and the frosting is INCREDIBLE. I’m kind of putting it on everything I bake now 😀

    The cake was sooo AMAZING!! We made it for a birthday and everyone loved it!! The frosting was the perfect addition to the cake! It tasted like a peanut butter cup! We used half of the frosting recipe for the cake because we prefer cake lightly frosted. I recommend starting with less powdered sugar that what it calls for in the frosting and then tasting from there. Love your recipes Monique!!

      So happy to hear that! It’s one of my all time favorite cakes to make 🙂

    I prepared this recipe for my birthday cake. It was spectacular!! My family loved the mix of flavors, especially the taste of the frosting. A total success.

    • replied:

      Love that!! Such a great recipe for celebrating 🙂

  • says:

    I made the cake using 2 8″ pans. The instructions say 20-30 minutes if using the 8″ pans. I figured this time was way off but I went ahead. After 25 minutes, the toothpick test was clean so I took them out to cool. About 10 minutes later I checked on them and they weren’t firm in the middle. I read the instructions closer and realized the times for the 6 and 8″ pans must be mixed up. They’re back in the oven. I hope they turn out ok; a lot of expensive ingredients here.

    • replied:

      Hi! The 8-inch cake pans won’t take as long because the cakes are not as dense, so the listed bake times for each pan size are correct. Let me know how they turned out!
