Last Wednesday it was Oestara (also known as Ostara and the Spring Equinox). I celebrated by making a Malteser slice with Cadbury Mini Eggs on top! (I usually celebrate with food and drink). As I mentioned in my Oestara Celebration Inspiration post, it's similar to Birdies Perch, which is a favourite of mine to make.
I first made it last year; it was called Malteser Fridge Squares and
the recipe was on the Red Nose Day site. The page with the original recipe is now gone but you can find the same
(or similar) recipe here, called Malteser Squares: https://www.redonline.co.uk/food/recipes/a500554/eric-lanlard-s-malteser-squares/
Update 14/4/25: Recipe went again but here it is on another site: https://ironchefshellie.com/2011/04/30/malteser-squares/
It was quite nice. Here's a picture:
