Using a standard sweet muffin recipe fill the muffin cups to three quarters full.
(You can use either a plain or chocolate flavoured batter).
Pipe approximately 10 grams of Barker's Custard Flavoured Patisserie Creme into the centre of the muffin batter.
Do not push the piping bag in too deeply - it should not be touching the bottom of the muffin paper.
Bake at 180°C for approximately 16 to 18 minutes or until golden brown in colour.
