Step-by-Step Instructions

1. 1.Prepare the pizza base

   Brush a 24 cm plain pizza base with a little melted butter.

   Place the pizza base into a preheated oven at 230°C (450°F) for about 5 minutes, just to warm it through.

3. 3.Spread the sauce

   Remove the base from the oven. Spread a generous amount of Nutella (chocolate hazelnut spread) evenly over the pizza base, leaving a small border for the crust.

4. 4.Add marshmallows

   Place small marshmallows, cut in half, all over the Nutella layer.

5. 5.Add chocolate chips

   Sprinkle milk chocolate chips and white chocolate chips over the pizza.

6. 6.Add banana slices

7. 7.Add candy bars

   Scatter chopped Mars bars (or your preferred candy bars) over the pizza.

8. 8.Final bake

   Return the pizza to the oven for another 5 minutes or so, until the marshmallows have melted and are slightly toasted, and the chocolate and candy bars are gooey.

9. 9.Serve

   Remove from the oven and serve warm.
