Creating the Elegant Black Forest Cake Roll is a straightforward process if you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a 15×10 inch jelly roll pan with parchment paper and lightly grease it.
2. Beat Eggs and Sugar: In a large mixing bowl, beat the eggs and granulated sugar together until thick and pale, about 5 minutes. Stir in the vanilla extract.
3. Combine Dry Ingredients: In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt.
4. Mix Together: Gradually fold the dry mixture into the egg mixture until just combined. Be careful not to overmix.
5. Spread Batter: Pour the batter into the prepared pan, spreading it evenly. Bake for 10-12 minutes or until the cake springs back when lightly touched.
6. Cool and Roll: Once baked, remove the cake from the oven. Immediately invert it onto a clean kitchen towel dusted with powdered sugar. Peel off the parchment paper and roll the cake tightly with the towel. Allow it to cool completely in this shape.
7. Prepare Filling: While the cake cools, whip the heavy cream and powdered sugar until stiff peaks form. Unroll the cooled cake, spread the whipped cream evenly, and sprinkle the cherries over the cream. Roll the cake back up without the towel and place it seam-side down on a serving platter.
