1. Preheat oven to 180° fan bake.

2. Place water, butter, sugar, & salt into a saucepan over medium heat until the butter has melted.

3. Add flour and cook for a further 2-3 mins, consistently stirring, so it doesn't stick to the bottom. Let sit at room temperature for 10 or so minutes to cool down a little before adding in the eggs & vanilla.

4. Put the dough into a wide tip piping bag & pipe it onto a lined oven tray; bake for 20 - 30 minutes and prick with a skewer before letting it cool (this helps them hold their shape).

When you're ready to serve, dip it in chocolate, cut it open, & scoop on your favourite ice cream.
