How To Make
Creating this elegant cake requires careful attention to technique but the results are absolutely worth the effort. Let me guide you through making perfect Black Forest Sheet Cake every time.
Make Vanilla German Buttercream First
In a heatproof bowl, whisk together 1/4 cup of the granulated sugar and the cornstarch for your Black Forest Sheet Cake buttercream. Beat in the 2 eggs until smooth. Set aside near the stove but away from direct heat.
In a medium saucepan, stir together the 1 cup of whole milk and the remaining 1/4 cup of granulated sugar for your Black Forest Sheet Cake. Bring to a simmer over medium heat, stirring occasionally. Watch carefully so it doesn’t boil over.
Once simmering, ladle about 1/3 cup of the hot milk into the egg mixture while stirring constantly to temper it for your Black Forest Sheet Cake buttercream. This prevents the eggs from scrambling. Slowly drizzle the tempered mixture back into the simmering milk, beating vigorously.
Cook over medium-low heat, stirring constantly, until thickened to the consistency of a tight pudding for your Black Forest Sheet Cake custard. This takes about 3 to 5 minutes. Beat out any lumps over low heat until completely smooth.
Remove from heat and stir in the 2 tablespoons of butter until melted and smooth for your Black Forest Sheet Cake buttercream. Press plastic wrap directly onto the surface to prevent a skin from forming. Refrigerate for at least 1 hour until fully chilled and very thick.
Once chilled, set the custard and the 1 cup of softened butter out together until they reach the same temperature for your Black Forest Sheet Cake buttercream. This is crucial for proper emulsification.
Beat the butter in a stand mixer until smooth and creamy for your Black Forest Sheet Cake buttercream. Add the custard 1 to 2 tablespoons at a time, beating well between each addition. Beat on high until very fluffy and smooth. Add the vanilla and salt and beat briefly to combine.
Prepare the Cake Pan
Preheat oven to 175 degrees Celsius or 350 degrees Fahrenheit for your Black Forest Sheet Cake. Make sure the oven is fully preheated before baking.
Grease a 9 by 13 inch baking pan generously for your Black Forest Sheet Cake. This prevents sticking.
Make the Cake Batter
Place the devil’s food cake mix, vegetable oil, eggs, and milk in a large mixing bowl for your Black Forest Sheet Cake. Mix on low speed until combined.
Increase to medium speed and beat for 2 minutes for your Black Forest Sheet Cake. This activates the leavening agents and incorporates air.
Stir in the cherry pie filling and mini chocolate chips for your Black Forest Sheet Cake. Fold gently until evenly distributed throughout the batter.
Bake the Cake
Pour the batter into the prepared pan for your Black Forest Sheet Cake. Smooth the top with a spatula to create an even layer.
Bake for 40 to 45 minutes until the top springs back when lightly touched for your Black Forest Sheet Cake. A toothpick inserted in the center should come out clean or with just a few moist crumbs.
Cool completely before frosting your Black Forest Sheet Cake. This takes about 1 to 2 hours at room temperature. Do not rush this step.
Make Dark Chocolate Ganache
Break the dark chocolate into small pieces and place in a microwave-safe bowl for your Black Forest Sheet Cake ganache. Add the milk or cream.
Microwave in 15 to 20 second intervals for your Black Forest Sheet Cake, stirring well between each interval, until completely smooth. Do not overheat or chocolate will seize.
Let sit a few minutes until warm but no longer hot for your Black Forest Sheet Cake ganache. This prevents it from being too runny when applied.
Assemble the Cake
Spread the German buttercream evenly over the cooled cake for your Black Forest Sheet Cake. Use an offset spatula for even coverage all the way to the edges.
Refrigerate for at least 15 minutes until set for your Black Forest Sheet Cake. This helps the buttercream firm up before applying ganache.
Pour the warm ganache over the chilled buttercream for your Black Forest Sheet Cake. Spread until smooth, working quickly before ganache sets.
How to Serve
This Black Forest Sheet Cake is perfect for elegant celebrations, dinner parties, special occasions, or any time you want an impressive sophisticated dessert. Store in the refrigerator. Let slices come to room temperature before serving for best flavor and texture. The cake pairs beautifully with coffee, tea, or a dessert wine. This makes 12 generous servings perfect for special gatherings.
