Preheat the oven to 375°F.
Place the crusts into a bowl and drizzle over the melted butter. Use your hands to ensure all of the bread is coated in butter.
Mix the sugar and cinnamon together in a smaller bowl.
Sprinkle the sugar over the crusts and gently mix through to make sure all of the crusts are coated evenly.
Spread the crusts on a baking tray in a single layer. Use two trays if necessary.
Bake for 8-10 minutes, or until golden brown in colour.
Leave on the tray for the few minutes to cool and become crisp.
To make the dip, place the desired amount of chocolate spread in a microwave-safe bowl and microwave in 10 second bursts until it reaches your desired consistency.
