Place chopped chocolate in a medium-sized heatproof bowl and set aside.

Pour heavy cream into a small saucepan and heat over medium/low heat just until cream comes to a simmer.

Once cream is simmering, remove from heat and pour evenly over chocolate (do not stir). Cover with foil or plastic wrap and let sit for 5 minutes.

After 5 minutes, remove cover and use a whisk to gently whisk chocolate and cream together until completely melted and smooth (note that this may take a minute and the mixture may look separated and piece-y at first, just keep stirring!). Try not to whisk too vigorously or you may incorporate air bubbles into the ganache.

Use as desired! If ganache is too thin immediately after preparing, let it sit for several minutes before using.
