You know what’s flying off the shelves like hot cakes? Cancer-crushing eclairs! 

Ready? Eclair Day’s 7th edition is set for Saturday, 13 March 2027.

  • For bakers

    Sell your eclairs to help kick childhood cancer. Every pastry sold makes a difference. 100% of the sales price goes to KickCancer to fund innovative research. Sign up now for Eclair Day on 13 March 2027 via this link.

  • For foodies

    Care for the kids and eat eclairs! Once a year, indulgence is a good deed: enjoy a delicious dessert and give childhood cancer a taste of its own medicine! Do you want to convince your local baker to participate? Become an Éclair Day ambassador.

It has been 7 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!

Sofie is our new ambassador!

Since late 2025, Sofie Dumont has gone all in as ambassador of Eclair Day. A successful chef who started her career as a pastry chef? The perfect match!

Sofie rallied bakers with a radio spot alongside Pierre, sold eclairs at the pre-sale event and shared the sweetest event of the year across all her channels. Onwards to many more eclairs with impact!
