A portion of this special-occasion dessert is all that is needed to provide big chocolate flavor.
To add a decorative powdered sugar garnish, place stencil on top of cooled pie. Use wire mesh sifter to sprinkle powdered sugar evenly over stencil. Carefully remove stencil to reveal the show-stopping garnish on pie.
Cover cooled pie and freeze up to 1 week. Thaw in refrigerator before serving.
