These aren't muffins, but do need a mini-muffin tray.

Mini Banoffee Pies
First you blind-bake the pastry in each mini-muffin well.
Then you add a slice of banana to the bottom of each pastry cup.
Pop a rolo on top.
Put back in the oven until the rolo only just starts to melt.
Take out the oven and serve hot with squirty cream on top.


For savory things, I make bite-size quiches in mine. Cheese, spinach and red pepper goes down a treat with a bit of fresh coriander.
