👨‍🍳 Instructions

1. 1

   {'id': 'step_0', 'step': 1, 'text': 'Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C). Line a 9x13-inch baking dish with parchment paper.'}

2. 2

   {'id': 'step_1', 'step': 2, 'text': 'To make the cake layers: Sift flour and baking powder together into a bowl; set aside. Beat 1 cup plus 2 tablespoons butter with an electric mixer in a large bowl until light and fluffy. Beat in white sugar, vanilla extract, and 5 egg yolks. Stir in flour mixture until just combined.'}

3. 3

   {'id': 'step_2', 'step': 3, 'text': 'Beat egg whites in a glass, metal, or ceramic bowl until foamy; continue to beat until stiff peaks form. Lift your beater or whisk straight up: the egg whites should form a sharp peak that holds its shape.'}

4. 4

   {'id': 'step_3', 'step': 4, 'text': 'Gently fold 1/3 of the egg whites into the batter, keeping as much volume as possible. Add the remaining egg whites, folding just until incorporated.'}

5. 5

   {'id': 'step_4', 'step': 5, 'text': 'Pour half of the batter into a separate bowl. Sift cocoa powder into one bowl of batter; stir until just combined.'}

6. 6

   {'id': 'step_5', 'step': 6, 'text': 'Pour white cake batter into the prepared baking dish, then spread chocolate cake batter on top. Pat cherries dry with paper towels, and sprinkle them evenly on top.'}

7. 7

   {'id': 'step_6', 'step': 7, 'text': 'Bake in the preheated oven until a toothpick inserted into the center of the cake comes out clean, 25 to 30 minutes; set aside to cool.'}

8. 8

   {'id': 'step_7', 'step': 8, 'text': 'To make the custard filling: Whisk cornstarch and 1/2 cup sugar together in a small bowl. Heat milk in a small saucepan just until hot but not boiling. Whisk in cornstarch mixture until smooth; bring mixture to a boil, whisking constantly, until mixture is thick and easily coats the back of a spoon, about 2 to 3 minutes. Remove from heat and stir in vanilla.'}

9. 9

   {'id': 'step_8', 'step': 9, 'text': 'Spread custard filling over cooled cake; press a piece of plastic wrap directly onto the surface of the custard filling so it doesn't form a skin. Refrigerate until set, at least 2 hours to overnight.'}

10. 10

    {'id': 'step_9', 'step': 10, 'text': 'To make the chocolate glaze: Place chocolate chips in a microwave-safe bowl. Heat at 30 second intervals, stirring each time, until just melted and smooth. Stir in oil until glossy.'}

11. 11

    {'id': 'step_10', 'step': 11, 'text': 'Spread chocolate glaze over chilled custard layer. When the glaze has set slightly, about 10 minutes, drag a fork lightly across the surface in wavy lines to create a wave pattern on the chocolate.'}
