Preparation

Step 1

Preheat oven to 350 degrees F. Butter a 10-by-15-inch rimmed baking sheet; line with parchment paper, leaving a 2-inch overhang on the two shorter sides.
Whisk together butter and sugar; whisk in egg, vanilla, and salt until combined. Add flour and cocoa, and mix just until smooth. Spread in prepared pan, smoothing top. Bake until cake is dry to the touch and edges begin to pull away from the sides, 10 to 12 minutes. Cool completely in pan.
Using paper overhang, life cake onto a work surface. With a serrated knife, halve crosswise. Place one half of cake, flat side down, on a large piece of plastic wrap. Spread with ice cream, smoothing with an offset spatula, then top with remaining half of cake, cut side down. Return assembled dessert to baking pan, and wrap tightly in plastic. Freeze until firm, about 2 hours.
Unwrap; using a serrated knife, cut into 8 rectangles, wiping blade with a damp kitchen towel between each slice. Serve immediately (or freeze, wrapped individually in plastic, up to 1 week.)
