Line an 8-inch square baking pan with parchment paper, leaving an overhang on two opposite sides.
Cut the butter into small pieces and chop the chocolate into chunks if not using chocolate chips.
In a medium saucepan, combine the butter, brown sugar, and caster sugar over medium heat. Stir constantly until the butter is melted and the sugars have dissolved.
Remove the saucepan from the heat and add the chopped chocolate. Stir until the chocolate is completely melted and the mixture is smooth.
Stir in the vanilla extract.
Pour the chocolate mixture into the prepared baking pan and smooth the top with a spatula.
Refrigerate the fudge until set, about 2-3 hours.
Once set, use the parchment paper overhang to lift the fudge out of the pan. Cut into squares and serve.
