Recipe

Preparation Time: 20 mins Cook Time: 25 mins Ready Time: 1 hr 45 mins


• preheat oven to 350 degrees f (175 degrees c). grease a 9x9-inch square cake pan.
• beat egg whites in a glass or metal bowl until stiff peaks form. lift your beater or whisk straight up: the egg whites will form sharp peaks.
• beat unsalted butter and white sugar together in a large bowl with an electric mixer until light and fluffy; beat in flour, baking powder, and 1 teaspoon salt. beat milk and 1 teaspoon vanilla extract into flour mixture; fold in beaten egg whites and chocolate chips. spread batter into prepared pan.
• bake in the preheated oven until a toothpick inserted into the center comes out clean, about 25 minutes. cool completely in the pan on a wire rack, about 30 minutes.
• beat 1/3 cup butter, confectioners' sugar, egg yolks, 1 teaspoon vanilla extract, and the pinch of salt together with an electric mixer until smooth; spread on the cooled cake.
• melt chocolate squares with 2 tablespoons butter in a microwave-safe bowl, about 30 seconds on high. allow chocolate mixture to cool slightly, then spread chocolate carefully over iced cake. refrigerate cake until chocolate is set, about 30 minutes.
