Preparation
Step 1
Chocolate Cake
• Preheat oven to 350°. Coat bottom and sides of pan with nonstick spray; line bottom of pan with parchment paper. Whisk flour and next 4 ingredients in a large bowl. Add oil, vanilla, and 1 1/4 cups water; whisk until smooth. Fold in chopped chocolate. Scrape into prepared pan; smooth top. Bake until a tester comes out clean when inserted into center, 35–40 minutes. Let cool completely in pan on a wire rack.
Peanut Butter Buttercream
• Combine sugar and egg whites in a medium metal bowl set over a saucepan of simmering water. Whisk constantly until sugar dissolves and mixture is hot to the touch, 3–4 minutes. Remove from heat; using an electric mixer, beat on high speed until cool and thick, 5–6 minutes. Beat in vanilla, then peanut butter. With mixer running, add butter a few pieces at a time, beating to blend between additions. Season with salt.
•Run a thin knife around pan to release cake. Invert cake onto a serving plate. Spread peanut butter buttercream over top. Garnish with chopped chocolate and peanuts. DO AHEAD: Can be made 1 day ahead. Store airtight at room temperature.
•Cut into 2-inch squares.
