Are you a baker and ready to knock out childhood cancer? Join us on Saturday, 14 March 2026, for the 6th edition of Eclair Day. On this day you’ll sell your eclairs to kick childhood cancer by every pastry sold. All funds raised will be donated 100% to KickCancer to fund research. Let’s unite our efforts for better treatments for children with cancer!

I am a caring foodie

Once a year, indulgence is a good deed: eat a good dessert and give childhood cancer a taste of its own medicine! During one whole day, eclairs will be sold to defeat children’s cancer. How cool is that?

Pierre Marcolini

It has been 6 years!

In 2019, Delphine Heenen and Pierre Marcolini took on a challenge: sell eclairs for one day to kick paediatric cancer. Since then, Eclair Day has become an annual event, driven by its godfather Pierre Marcolini and many supportive bakers across Belgium! Last year, 500 bakeries prepared 70,000 eclairs, raising €200,000 for research in just one day! Are you ready for the 2026 edition? Whether you are a baker or a foodie, join us in this campaign to knock out childhood cancer, together!
