In a small saucepan, combine the chocolate chips, butter, and corn syrup.

Place the saucepan over low heat and stir constantly until melted and smooth.

Remove from heat and stir in the vanilla extract.

Let the mixture cool slightly.

Line a baking sheet with parchment or wax paper.

Using a spoon or piping bag, drizzle the chocolate over your dessert.

Allow the drizzle to set at room temperature or refrigerate for quicker results.
