- Fill cupcake liners about 2/3 full.
- Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
- Let cool in the pan for a few minutes, then transfer to a wire rack to cool completely.
- Beat softened butter with an electric mixer until light and fluffy.
- Gradually add sifted powdered sugar, alternating with heavy cream, until desired consistency is reached.
- Stir in vanilla extract and salt.
- Melt chocolate chips in a microwave or double boiler until smooth.
- Let cool slightly, then transfer to a small Ziploc bag or piping bag.
- Frost cupcakes with vanilla buttercream.
- Cut a small hole in the corner of the Ziploc bag (or piping bag tip).
- Pipe concentric circles of melted chocolate on top of the frosting.
- Using a toothpick or skewer, drag lines from the center of the cupcake outward to create the spiderweb effect.
