Is it a big macaron? Is it a little green burger? No! It’s a Giant Mofo Matcha Whoopie Pie!



um…. what is a whoopie pie?

Well, I didn’t know either until last week when Google explained it to me. Not to be confused with a whoopie cushion, a whoopie pie was basically two little round bits of chocolate cake with cream in the middle.

Sounds good?

Sounds good.

I think it’s a very American thing because well, all the Americans seem to know what they are and all of the rest of the world, we were like, whoopie what? And the fact that every recipe uses marshmallow fluff which you can only get in the US (or Selfridges for expensive or eBay for £1.99).

Anyhoos, Teapigs emailed me the other day, saying that a bunch of people had been asking them to make matcha whoopie pies because chocolate is like, so 2009.

I, ever the lovely obliging person that I am, agreed to make some. Oh, and there is that tiny fact that I am in love with all things matcha.

So I went and googled a bunch of whoopie pie recipes and adapted my own, evicting the so very uncool cocoa powder and adding a totally made up portion of matcha powder instead.

It worked, and the results? Six enormous matcha whoopie pies, the size of a cheeseburger including the pseudo cheese oozing from the side. Don’t worry, it doesn’t actually drip, it’s a mix of marshmallow fluff and icing sugar which tries to drip, then dries.


Oh, and cos you’re all so well behaved, here’s a little photo of some greedy person trying to eat my whoopie pie.

If you can’t find matcha at your local Chinese or Japanese grocery store, get some from Teapigs!

matcha whoopie pies
2 cups plain flour
1/4 cup matcha powder
1 1/4 teaspoon baking soda
1 teaspoon salt
1 cup well-shaken buttermilk (I used natural yoghurt as a buttermilk substitute)
1 teaspoon vanilla extract
110 grams unsalted butter, softened
1 cup packed brown sugar
1 large egg
For the filling:
110 grams unsalted butter, softened
1 1/4 cup icing sugar
2 cups marshmallow fluff
1 teaspoon vanilla extract
  1. Preheat oven to 175°C/350°F.
  2. Mix together flour, baking soda, matcha powder and salt in a bowl until combined.
  3. In another bowl, stir together buttermilk (or substitute) and vanilla extract.
  4. In a large bowl, beat the butter and brown sugar together until light and fluffy (about 5 minutes), then add the egg and beat until well combined.
  5. Reduce the speed to low and mix in the flour, alternately adding the buttermilk mixture as well. Mix until smooth.
  6. Scoop 1/4 cup portions of batter and lay on baking sheet about 2 inches apart. Bake in pre-heated oven for about 12 minutes, or until the cake bounces back when touched.
  7. When ready, remove from oven and cool on wire rack.
  8. For the filling, beat together the butter, icing sugar, marshmallow fluff and vanilla extract until smooth.
  9. Spread the filling on a flat side of a cake, and top with another portion of cake.

ps. I’m gonna try make little ones next time.

45 Thoughts on “Is it a big macaron? Is it a little green burger? No! It’s a Giant Mofo Matcha Whoopie Pie!

  1. I really should use green tea more frequently in baking, it really is so good.
    Love the look of and concept of the whoopie pie, fabulous 🙂

    BTW I really like your writing style.

    • Thank you! My writing style is basically a verbal regurgitation of what goes on in my head, but thank you. And yes, matcha is great for all kinds of things, including baking! 🙂

  2. Jesus those are huge!! but boy do they look good. I think I need to make some whoopie pies not sure I haven’t yet

  3. Love your whoopie pie! Love that dripping marshmallow too. And that’s a lot of matcha. Don’t think I can afford that much as it’s expensive to get the real matcha here.

    Didja know they’re called whoopie pies bc farmers who would open their lunch pails upon seein their wives had packed them this sandwich pie would yell whoopie!!! That’s a beauteous green one for sure! And as for that steak resto, im totally down for the best steak in paris. Let’s go!!!

  5. Edd: I know they’re enormous! LOL but I did follow a recipe! And yes, you should definitely make some 🙂

    The Cooking Ninja: It is a lot of matcha.. but then again the matcha portion is really to your taste. I love the bitter matcha flavour so I always add heaps!

    yutjangsah: LOL I read that on wiki, that is so funny.. I betcha theirs weren’t green though. Unless it was green with mould. Which mine isn’t. I promise. AWESOME… steak in Paris!! 😀

    haha well written post 🙂 and that whoopie pie is huge!

  7. I’m dying to make some whoopie pies. And although it’s like 25 quid a tin, I am seriously considering ordering some of this matcha from Teapigs.

    Do they taste as good as they look? I hope so.

    The branch of Spar in Walthamstow Village sells Marshmallow Fluff along with various other US favourites (no idea who is buying them here but they keep stocking it). Ironically today I noticed they were also selling whoopie pies. Our local Spar rocks!!

  8. darren j: hehe thank you. And it is!

    Sarah: I know, matcha is definitely not cheap. Teapigs does sell some fantastic matcha, but you can also check if you’re near a Chinese or Japanese grocer. The whoopie pie does taste pretty good – I especially just like the matcha cake bit (the filling is really sweet) and am already formulating ideas for making little matcha cakes using the same recipe 🙂

  9. My darling that looks divine! I’m just making some of my own – can’t wait to see how they turn out. And can’t wait to see you tomorrow! Whoopie! =) xxx

    • Are you making some too?? OMG can’t wait to see how yours turn out! I’m going to make some teeny weeny ones soon, these guys are like entire meals! xx

  10. This looks utterly delicious! I am matcha’s biggest fan, and can’t get enough of it. I am in Seoul now, where they do fantastic matcha lattes – something I would never have thought of, but it works brilliantly. I am sure matcha would be very popular in the UK if it were better known. I learnt how to make matcha creme brulee with Reiko Hashimoto (of Hashi cooking) which also works a treat. Maybe we should consider posting a series of matcha recipes – what do you think?

  11. Kavey: thank you honey! 🙂

    The London Foodie: OMG you and I are going to be best friends! Guess what is next on my matcha list (and I have the ingredients waiting to go this weekend??) – matcha lattes!! 😀

  14. Too cute, love whoopie pies!!

  15. wow. WOW they are maHOOSIVE.


  17. ShopEatSleep: LOL I know, that looks pretty mad right? To be honest I thought it was going to drip and I sat there going DON’T DRIP DON’T DRIP DON’T DRIP until it stopped. *phew*

    sweetlife: I love them too now 🙂 Although they are so big I don’t think I’d describe them as “cute”. More like “mammoth”.

    Yinnie: They sure are 😉

    annabel: Try them!!

  18. I LOVE! whoopie pies are so amazing. And yes, they are so not known here. Gorgeous – i want some pleasseeeee.

  24. ZOMG that thing is as big as your head.

  25. Kitchen Butterfly: hehehe you made some matcha macarons? I am utterly untalented and cannot make macarons *sigh* but I will happily eat them!!

    Sasa: It IS. Ma-hooooo-sive.

  26. Whoopie pies are my new obsession. Have you been to Hummingbird Bakery!! Red Velvet and Banoffee to name but 2 flavours. Delicious!

  27. Yum! Love whoopie pies and with matcha?! I loved the little matcha cakes I could find while visiting Japan a couple of years ago.. and there is a little Asian market in town that I’m going to have to check out now!

  28. holy moly! me thinks me has a heart attacks! gimme gimme gimme!

  29. Evan: I am SO obsessed with all things matcha (in case you haven’t noticed) – I would love to be in Japan and surrounded by all things matcha!

    Amy: Haha the filling (marshmallow fluff) will give you a heart attack on its own!

    girl paraphernalia: indeedy *nom nom nom*

  30. Mmmmm this looks out of this world! I’m curious to try to make these ‘whoopie pies’. I’ll let you know if I ever do. *still drooling*

  31. Wow this looks awesome..I am drooling…

  32. Here’s an idea to use my matcha powder ! As for the marshmallow fluff : maybe one day we will find some in France.

  33. It took me a while to find in London too! I actually mail ordered the bottle for this and then found it at Selfridges!

  34. Loving the look of these matcha whoopies! I’d like to try making them but wondered if you have the full metric measurements. The cup conversions I’ve found all differ. Thanks 🙂

  35. Wilton (a US company) makes a Whoopie Pie tin that you can use to portion control your treats. They only ship retail purchase in the states but maybe you can use this as an idea or find a local retailer who could order it. Another option is if you have a friend in the US to have them buy the tin and Marshmallow Fluff and ship it as a gift. 😉
