Have you ever heard of Pi Day? It’s the celebration of the mathematical number referred to as “Pi” (after the greek letter “π”). The first digits of the number are 3.14, so Pi Day falls on the 14th of March each year. Yep, it’s a bit geeky. But who doesn’t love a bit of geeky fun!
To get into the mathematical spirit this Pi Day, I made some Pi-shaped cookies! And the best bit – they’re loaded with brain foods, so will 100% definitely make you more intelligent*.

Brainy Blueberry Cookies Recipe for Pi Day
- 450g plain flour
- 125g caster sugar
- 125g coconut oil
- 125g golden syrup
- 1 teaspoon of vanilla extract
- 1 large egg
For the icing:
- 15-20 blueberries
- Approx. 150g royal icing sugar
- 1 tsp raspberry jam (optional)
- Beat the coconut oil and sugar together with the vanilla until smooth and creamy. Add the
egg, golden syrup and flour to the mixture. Mix until the dough starts to come together.
- Press the dough into a neat ball by hand, drawing in any flour left on the sides of the bowl.
- Roll out to 5mm thick and chill for an hour or more.
- Cut out the cookies before arranging on a tray. Bake at 170degrees (fan) for 9-11 minutes until lightly golden.
- To make the icing, mash the blueberries and jam together with a fork. Microwave until the mixture looks liquid and jammy.
- Push the blueberries through a sieve to extract the juice. Mix the royal icing sugar with the juice until it resembles the thickness of toothpaste (you may need more or less sugar than the 150g I specified in the ingredients). Reserve the pulp.
- Fill a piping bag fitted with a small round tip with the purple icing and use to pipe around the edge of the biscuits. Once the lining is complete, return the pulp to the remaining icing and add water drop by drop so that the icing has a very runny consistency and finds its own level quickly. Use the runny icing to flood ice the biscuits.
Okay, so these cookies might not turn you into the next Einstein… but shaping them into a mathematical symbol is good enough for me! Happy Pi Day! – Gareth.
