Directions

For frosting: Combine all ingredients in heavy large saucepan.

Whisk over medium heat until chocolate melts and mixture is smooth and just begins to bubble, about 8 minutes.

Refrigerate until just thick enough to spread, stirring occasionally, about 1½ hours.

Meanwhile, prepare cake: Preheat oven to 350℉ (180℃).

Line 15 ½×10 ½×1 inch baking sheet with foil, leaving overhang.

Grease foil.

Sift ½ cup sugar, cocoa powder, cake meal and potato starch into medium bowl.

Combine egg whites and salt in large bowl.

Using handheld mixer, beat whites until soft peaks form.

Gradually add ½ cup sugar; beat until stiff but not dry.

Using same beaters, beat yolks and ½ cup sugar in another large bowl until thick, about 2 minutes.

Gradually beat in oil, then nondairy creamer.

Add dry ingredients; beat just until blended.

Fold whites into yolk mixture in 3 additions.

Spread batter in prepared pan.

Bake until tester inserted into center comes out dry and cake feels firm to touch, about 20 minutes.

Cool cake in pan rack.

Freeze cake until firm, about 30 minutes.

Using foil as aid, lift cake onto work surface.

Cut cake crosswise into 3 rectangles, each about 5×10 inches.
