Thermomix Irish cream whoopie pies

No Ratings So Far
Thermomix Irish Cream Whoopie pies are perfect to celebrate St. Patricks Day. These delicious little chocolate sandwiches are filled with a boozy Baileys buttercream frosting. Probably the best combination since the jam sandwich are these Thermomix Irish Cream whoopie pies. Chocolate and Baileys go so incredibly well together and create a delicious, naughty treat for anyone who feels like it. Don't worry, I won't tell anyone if you indulge. The cakes are so light and fluffy and taste beautiful. Because the chocolate is melted with the butter and whisked into the eggs, it creates a much lighter texture, almost like chocolate mousse. And in combination with boozy Baileys, it makes a perfect treat this St. Patricks' day (or really any other day). The key to making buttercream is patience. This recipe includes step by step instructions to the perfect buttercream. Just make sure when making buttercream to always start by creaming the butter first. It's best to do that on a higher speed. Then you insert the butterfly whisk attachment and cream it at least 3 minutes. If you have a larger quantity, increase that time. Scrape down and then put it on for the same time again while slowly inserting the icing sugar. Do not be tempted to add too much icing sugar or it may split, get lumpy or just get too dry. Give the butter some time to work and be patient. It will work out well. I've had many fails myself because I was being impatient and thought I could trick that butter. At the end, always add a bit of liquid. In this case we added Baileys. You can also add water or any other alcohol or liquid you like. It will make sure that the buttercream achieves the right consistency and get really smooth. Don't add too much immediately, a drop at a time is sufficient to make a big change to the buttercream consistency. Once finished, you can store the buttercream in the fridge for up to one month if you have any leftovers. Just make sure you soften it in the Thermomix first before using it again. Have you ever had an accident with buttercream? Or is there something that you do differently that works really well? Leave me a comment.


Irish cream whoopie pies:

  • 150 g dark chocolate
  • 125 g butter
  • 3 eggs
  • 225 g caster sugar
  • 1/2 tsp vanilla extract
  • 250 g plain flour
  • 30 g cocoa powder
  • 1/2 tsp baking powder

Baileys buttercream:

  • 100 g butter
  • 30 g Baileys or Irish Cream + extra drops to finish off
  • 200 g icing sugar


  1. Preheat the oven to 180°C.
  2. Line two baking trays with greaseproof paper.
  3. Place the chocolate in the mixing bowl. Blitz 7 Sec. / Speed 9.
  4. Add the butter and melt 5 Min. / 45°C / Speed 1. Remove and place in a separate bowl until later.
  5. If you don't have a Thermomix, place the chocolate and butter in a small saucepan and, on lowest heat, melt until smooth. Place aside until later.
  6. Clean the mixing bowl. Insert the butterfly whisk attachment.
  7. Crack in the eggs. Add the caster sugar and vanilla extract to the mixing bowl. Mix 4 Min. / Speed 3. After 1 minute, slowly pour the chocolate through the lid in a thin stream.
  8. Remove the butterfly whisk attachment. Add the plain flour, cocoa powder and baking powder to the mixing bowl. Combine 30 Sec. / Speed 4.
  9. If you don't have a Thermomix, crack the eggs in a medium sized mixing bowl. Add the sugar and vanilla extract and mix until pale and fluffy. While whisking, in a thin stream, pour in the chocolate until well combined. Sieve in the plain flour, cocoa powder and baking powder and, using a hand whisk, fold under until well combined.
  10. Place tablespoons worth of mixture on the tray with a small gap in between. Bake in the oven for 12-15 minutes. Remove and leave to cool.
  11. Meanwhile, to make the Baileys buttercream filling place the butter in the mixing bowl. Mix 30 Sec. / Speed 4.
  12. Insert the butterfly whisk attachment. Add the Baileys and mix again 1 Min. / Speed 3. Scrape down.
  13. Mix again 2 min. / Speed 3. While mixing, slowly add the icing sugar. At the end, you can add another small splash of Irish cream if the cream is a bit too thick or just to make it a tad more boozy. Remove the butterfly whisk attachment.
  14. If you don't have a Thermomix, place the butter in a medium sized mixing bowl. Using an electric whisk, mix until pale and fluffy. Add the baileys and whisk again for another 3-4 minutes. Then, while whisking, slowly add the icing sugar until everything comes together as a smooth icing. This may take up to 5 minutes. Finish off with a little drop of Baileys if you feel it is slightly dry.
  15. Fill into a piping bag with a plain nozzle and pipe big dollops on half of the whoopie pies. Top with another cake so that you have sandwiches. Enjoy!

    I made these at the weekend and they were absolutely delicious! I was worried that the Whoopies would be too dry but they were very light and moist. I swapped the Irish cream with regular to make them child friendly and the buttercream recipe worked brilliantly. They have been interestingly renamed ‘chocolate burgers’ in our house… Many thanks for the recipe!

    Could you use GF flour? We have a dinner party and one guest needs GF. Thanks

      Yes of course:)

    Would it be possible to substitute another type of flour to make a GF version?

    • admin admin on April 23, 2018 at 7:19 am

      Yes, you could use GF plain flour as it comes pre mixed or you could use a mixture of rice flour, corn flour and buckwheat flour.
