Step 1: Prepare the pizza base

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

Step 2: Pre-bake the base

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

Step 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.

Step 4: Add marshmallows

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

Step 5: Add chocolate chips

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

Step 6: Add banana slices

Arrange slices of banana on top of the pizza.

Step 7: Add candy bars

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

Step 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.

Step 9: Serve

Remove from the oven and serve warm.
