To make ganache frosting, pour baking chips into a large, heat-safe bowl. Bring heavy cream to a simmer in a small saucepan over medium-low heat, stirring frequently.
Pour batter into prepared cupcake liners, about 2/3 full. Bake in preheated oven for 16-18 minutes, or until a toothpick inserted in center comes out clean. Allow to cool completely on a wire rack.
