Creating an impressive Black Forest Trifle is a joy when you follow these simple steps:

1. Prepare the Cake: Bake the chocolate cake according to the package instructions or your favorite recipe. Allow it to cool completely before cutting.

2. Make the Whipped Cream: In a mixing bowl, whip the heavy cream until soft peaks form. Gradually incorporate powdered sugar and vanilla extract, continuing to whip until stiff peaks form.

3. Cut the Cake: Once the cake is cooled, cut it into small cubes or slices, about 1-inch in size.

4. Layer the Trifle: In a large glass trifle bowl or individual serving glasses, start with a layer of chocolate cake.

5. Add Cherries: Spoon a layer of cherries over the cake, drizzling some cherry juice on top for added flavor.

6. Add Whipped Cream: Next, add a layer of whipped cream over the cherries.

7. Repeat Layers: Continue layering the cake, cherries, and whipped cream until all ingredients are used, finishing with a generous layer of whipped cream on top.

8. Garnish: Sprinkle chocolate shavings on the top layer of whipped cream for an elegant finish.

9. Chill: Cover the trifle with plastic wrap and refrigerate for at least one hour to allow the flavors to meld beautifully.

10. Serve: Once chilled, your Black Forest Trifle is ready to be enjoyed!
