This Peanut Butter Dulce De Leche Banana Cake is a banana layer cake with peanut butter and dulce de leche Italian Buttercream.

From time to time someone will ask me to review a product.

Oddly enough, most of the time it is not food related(wtf?)

But when I saw a jar of Blake Makes Peanut Butter Dulce De Leche, it was I who was the one wanting to get a jar and review it.

How could I not?

Are you kidding me?

YUM.

I signed up on his blog to receive a free sample in the mail.

A few days later, two cute little jars arrived at my mailbox.

I knew right away when I heard about the peanut butter dulce de leche that I wanted to do something with bananas.

I love banana and peanut butter(it’s the Elvis in me) and I love caramel and bananas.

So those ingredients sounded like a winner combo to go with bananas…and it was.

Now you may be saying to yourself I can’t get ahold of that.

And I feel ya.

You can make your own by simply adding 4 TBSP of regular dulce de leche with 1 TBSP peanut butter powder.

This is an very moist cake that I usually make with cream cheese frosting but decided to mix it up a bit.

I did have problems with my frosting.

I had beautiful Italian Meringue Buttercream, right up until the point that I added the peanut butter dulce de leche.

Apparently the frosting was not in favor of that.

It still worked out nicely and the taste was spot on so I overlooked my temperamental frosting.

Sadly right now this is not available to the public but I am hoping that it will be one day.

P.S. It’s a great day to buy my cookbook Holy Sweet!

  1. That’s it. If I get a jar of PBDDL, I am sending it to you so in return you can make this for me and send it my way 🙂

  2. mmmmm…. i’m so jealous; i only got one jar and figuring out what to do with it (besides eat it by the spoonful) is proving to be difficult.

    so what if the buttercream wasn’t happy when you added the PBDDL – i’m sure it still tasted heavenly! 🙂

  4. Wow, Peabody! This looks AMAZING! I think I’m getting a toothache just looking at the PBDDL, but that toothache would soooo be worth it!

  5. I want some!!! Have a link as to where I can get some or a brick & morter store.

    I have a couple of banans on my counter hat are singing “make me, make me”

  9. mmmm, looks so good! Finally, the blog pays dividends and you get some worthy samples! Totally worth it.
    That PBDDL will probably never make it over the ocean to here. Darn. I will forever have it on my brain.

  10. OMG! If I weren’t married, I’d seriously be asking you out on a date after seeing this post. I absolutely love peanut butter (obviously), caramel (obviously) and bananas. Throw in some chocolates, and I’m…”Hopelessly devoted to you!” This cake looks spectacular! I’m not announcing it on my blog just yet, but we’re working on a pineapple dulce de leche now. You’ve heard it here first! bk

  15. yum, yum, yum. he contacted me a while back about trying this stuff out… i better hustle over to his blog and see if i can still get some!

  18. Peanut butter dulce de leche?! YES!
    I hope it’s in the stores someday.

    This is a nice looking cake. I love the banana-peanut butter-caramel combo.

  21. OH MY!!! This looks absolutely decadent, seriously, my jaw dropped when I saw it. Dulce de Leche, with mascarpone and bananas… wow… that’s all I can say.

    Reply

  23. Peabody, I’m going to repeat exactly what you said: “Peanut Butter Dulce De Leche! Are you kidding me?” – I couldn’t have said it better myself! My goodness, I too have always loved the combination of peanut butter, bananas, AND caramel (thank goodness for vegan caramel! haha); so between your banana cake and that peanut butter dulce de leche frosting, I SERIOUSLY believe that I have entered heaven… although I DO feel quite envious that you got to review such a luscious, decadent, perfect product, so I don’t know if I’m so angelic after all, haha :0)

  32. Not fair! This looks too good to eat! I have 6 days until I have to fit into a party dress and I think I have just gained 10 pounds! Oh – but it sure was worth it!

    Reply

  33. Yum! I have so not had time to make anything yet (and AMAZINGLY the jar is still sitting unopened, next to my bed, yes, so I have to be reminded every morning that I have yet to make anything with it!) but I’m really excited about your recipe. I do believe I have decided to also do something with banana…it really does seem like the perfect combo!

  35. WHAT?? Why haven’t I seen a jar of that stuff? Will I ever see a jar or will I go through life haunted by a missed opportunity to eat food of the gods???? Sigh.

  37. Thank you for stopping by my blog and leaving a comment…cause I love the delightful surprise of visiting someone new and finding such a stunningly beautiful blog!

    Your recipes and photographs are wonderful!!!

  41. Dulce de leche is a true Brazilian passion, Pea (we love the stuff here, it’s amazing). Peanut butter is something I don’t buy because I eat the entire jar when I do. Those 2 together must be fantastic!

    That cake looks yummy! I love how freckled it looks (it’s the freckled girl in me). 🙂

    Reply

  43. What a mouth-watering confection! At the moment I can’t even get dulce de leche here in the NL, so I’m green with envy that you got your hands on PBDD! I guess I will have to continue in my attempts at making it myself.

  44. I am right there with you and the PB, caramel and bananas.. OH YEAH BABY!! Your cake looks luscious.. too luscious.. I can’t keep looking at it! You hate my thighs, don’t you? 😛

    heeee!

  50. My friends and I were *just* talking about banana cake. This looks so good it’s unbelievable! I know where I’m getting my recipe for one now! Thanks! 🙂

  51. This looks to die for. This is my first time here, I was referred by Brilynn, but it seems I’ve found another peanut butter lover! I guess peanut butter is a popular ingredient, it sure makes that cake look like a slice of heaven. I wish I had some right now. Excellent photography!
