Delicious chocolate chip and banana cookies, sandwiched with salted caramel buttercream and caramel sauce… Banoffee sandwich cookies are NEXT LEVEL! 

Now, when I post anything that is cookie, caramel, or banana related it tends to go a bit nuts. So, I decided to answer all of your dreams and requests in one go and create these bad boys… BANOFFEE SANDWICH COOKIES!

These cookies are based on a combination of various recipes of mine over time, and I am 100% okay with that – sometimes that is how the best creations are created – marrying beautiful other recipes together for the dream and ultimate combos!


For these cookies, I started off by thinking of my favourite cookies ever – my classic NYC cookies – and my vegan cookies as well. It’s sorta hard sometimes to add a ‘wet’ ingredient to a cookie without it ruining the texture or baking, and the banana counts as wet in this recipe. 

When I made my vegan cookies I used milk as a substitute, but bananas can work so well to replace the egg as well, which I hadn’t done before. One little note I should make here – I don’t tend to use bananas as I can’t eat them – weird I know. Unsure why it just doesn’t agree with me! 

Cookie dough

But anyway – as these banoffee sandwich cookies were going to turn out super chunky because of having to sandwich them, I did NOT make them NYC size. If you did, you’d end up eating about 3-4 cookies worth of cookies by the time you assembled them and that is even too much for me. 

This recipe makes 8 sandwich cookies, or 16 cookies if you don’t fancy the sandwich bit – so I used a 5cm cookie scoop to make my cookies appear, and it worked perfectly. By the time the cookies bake and spread somewhat, they get to a decent size.


I used dark chocolate chips because I love the flavour with the sweetness of the caramel, but you can of course use milk chocolate, white chocolate – or even a combination! There are no rules when it comes to chocolate chips.  

That’s one thing that I particularly love about any cookie bake… DELICIOUS! 


For the buttercream, I made a really simple salted caramel buttercream – and yes, you can leave out the salt if you don’t like it salty, but that is up to you! Piping a swirl of buttercream around the edge of half of the cookies, and filling them with some caramel sauce was the ultimate idea ever. 

As you are adding caramel to buttercream it is really important to use BLOCK BUTTER for the buttercream – any form of spread will be too soft after you add the caramel and I don’t want anyone to have any cookie disasters if I am being honest.

If you do it this way, the only banana is in the cookie dough – so it is a relatively subtle flavour, but it is there. You can add a chunk of banana to the middle, or even add some chopped up dried banana chips to the cookie dough if you fancy making it more banana-like though! 

Enjoy these cookies because yes, they are the absolute ultimate cookie, caramel and banana combination and I am sure you are all going to love them! Jane x

    Did u have to squash yours mine were like domes and iv had to squash first batch

    • Jane's Patisserie on February 27, 2023 at 3:56 pm

      Hiya! This can be due to the oven being too hot, over working the dough, or rolling the balls too tightly! Hope this helps! x

  2. Gemma on February 23, 2023 at 10:12 am

    Hi I made these this morning but I would like a bit more of the banana flavour to come through. Any suggestions?
    Thanks 😊

    • Jane's Patisserie on February 27, 2023 at 3:49 pm

      Hiya! You could always try some banana flavouring! Hope this helps! x

    5 stars
    Hi Jane what weight can the cookie dough be as I don’t have a 5cm scoop. Thanks

    • Jane's Patisserie on October 7, 2022 at 10:58 am

      Hiya! I would just add up the weight of the cookie dough and divide by how many cookies you are baking. Hope this helps! x

  4. Tom on July 15, 2022 at 6:26 pm

    Hi Jane,

    Have you tried making these totally vegan before? Replacing the butter for vegan block and no caramel filling.

    Thanks in advance!

    • Jane's Patisserie on July 26, 2022 at 2:32 pm

      Hiya! I have not – however it is definitely worth a go! Hope this helps! x

    Always love your recipes! If I wanted to adapt these and make them into nyc cookies rather than sandwich ones, do you think I could freeze some caramel to put in the middle? (Similar to your biscoff stuffed ones) If so how much do you think I would need? (Assuming the same amount of cookie dough!

    • Jane's Patisserie on May 23, 2022 at 10:43 am

      Hiya! Unfortunately caramel does not freeze! Hope this helps! x

    • Debbie O'Connell on May 29, 2022 at 7:07 pm

      I adapted these to make caramel stuffed banana cookies and they turned out great! I made caramel sauce a few weeks ago and froze it. So when I made these cookies I just put a little ball (the size of a grape) in the middle of each cookie and they were delicious! I added chocolate chips and fudge chunks to my cookie mix. and sprinkled corse salt onto it after cooking. Yum!

    • Jane's Patisserie on June 6, 2022 at 11:59 am

      oh wow that sounds delicious, enjoy! x

  6. Jean on May 15, 2022 at 5:01 pm

    Thanks for adding a “no egg” recipe, I have a friend who cannot have eggs. Trying the recipe today 🙂

  7. Sarah on May 13, 2022 at 1:19 pm

    These look amazing! Is there anyway to measure out the dough without using cookie scoops?

    • Jane's Patisserie on May 17, 2022 at 1:55 pm

      Hiya! Yes, you can split the total weight of the dough equally and weigh them. Hope this helps! x

  8. david moss on May 12, 2022 at 5:25 pm

    Hi Jane, was thinking of dividing the cookie mixture into 16 similar to the NYC cookies rather than guessing with a scoop, what do you think, should work the same? love these recipes.

    • Jane's Patisserie on May 17, 2022 at 1:48 pm

      Hiya1 Sorry, I am slightly confused – with a scoop this measures the cookie for you, and the NYC Cookies are much larger? x

    • david moss on June 3, 2022 at 10:47 am

      Hi Jane, sorry, for the confusion, i thought i would be able to weigh them out to equal weight, but
      didn’t realize the mixture would be more sticky, had trouble keeping them roughly the same size.
      did you use a cookie cutter after you cooked them as yours seem perfect round in the pictures.
      Thank you.

    • Jane's Patisserie on June 10, 2022 at 11:51 am

      Hiya! Yes you can just circle them with a cookie cutter whilst fresh from the oven to get a rounder shape! Hope this helps! x

  9. Shirley on May 7, 2022 at 6:05 pm

    Made these today and they are amazing 😍

  10. Karen on May 6, 2022 at 3:45 pm

    Could you use milk chocolate chips instead of dark ones would they still work thanks they look delicious

    • Jane's Patisserie on May 11, 2022 at 12:10 pm

      Hiya – yes this should be absolutely fine! Hope this helps! x
