Considering this fudgy dark chocolate date frosting is made with dates, you'd think it'd be a little gritty, but it actually turns out incredibly smooth, spreadable and creamy.
Place the dates in the basin of a blender, or in a tall, narrow container if using an immersion blender. Pour boiling water over dates and let sit for 10-15 minutes or until the dates are very soft.
Blend water and dates on high until very, very smooth. Add in the cocoa, salt and vanilla and blend until well-mixed.
Chill the frosting until completely cool (about 3 hours) before spreading on cupcakes.
