Boil your 4 eggs and once they are ready (roughly 10-12 minutes) drop them in an ice bath.
Start by prepping the dough: in a medium bowl, beat the eggs with the sugar for a couple of minutes with a whisk.
Add the flour, baking powder, vanilla and chopped butter, then work with your hands until everything comes together in a ball. Cover in cling film and let it rest in the fridge for 30 minutes.
Once it has rested, remove it from the fridge and roll it on a floured surface until it's roughly 1cm thick. Cut in the shape you prefer - traditionally it would be a basket, a crown, a bell or a dove - and decorate with some extra pastry, making sure you keep some on the side for the crosses on top of the eggs.
We went for bells and decorated the top with some rolls tied together. Cut all your four shapes and place the boiled egg in the middle, then cover the egg with two strips of pastry to make a cross.
Brush all the pastry with milk, then drizzle the rainbow sprinkles on top.
Turn on the oven to 180°C and bake your cookies for 15 minutes.
Let them cool off completely before digging in!
Notes
These keep fine for a couple of days, and make the perfect table decor for Easter Sunday!
