6. Stage

Place 1 cake layer on a cardboard round cut to the same size as cake. Spread half of the filling onto the cake layer, spreading just slightly past the edge of the layer (about 1 cup). Repeat with a second cake layer and remaining filling. Top with final cake layer. Smooth excess frosting flush with the sides of the cake. Refrigerate cake until chilled, about 20 minutes.

7. Stage

Place chocolate in a 4-cup glass measuring cup with a spout for the glaze; set aside. Bring cream and corn syrup to a low simmer in a small saucepan over medium-low, stirring occasionally. Pour cream mixture over chocolate, and let stand 2 minutes. Stir glaze with a spatula until completely smooth. Let stand at room temperature, stirring occasionally, until cooled to 100 to 105 degrees F (37 to 40 degrees C), 4 to 10 minutes. Glaze should be pourable and fluid. Dotdash Meredith Food Studios

8. Stage

Remove chilled cake from the refrigerator, and place on a wire rack or inverted bowl inside a rimmed baking sheet. Quickly pour glaze over top of cake, allowing glaze to flow down the sides, making sure cake is completely covered. A spoon can be used to scoop up and reuse glaze to drizzle and coat sides. Let stand for 1 minute, allowing excess glaze to drip off the sides. Run an offset spatula around bottom edge of cake to remove any drips. Chill cake until glaze is set, about 1 hour.
