Preheat your oven to 350°F (175°C) and prepare a rectangular baking pan by greasing it or lining it with parchment paper.

In a large mixing bowl, whisk together 4 large eggs and 1 cup of sugar for about 5 minutes until light and fluffy.

In a separate bowl, sift together 1 cup of all-purpose flour, 1 teaspoon of baking powder, and ¼ cup of cocoa powder. Gradually add to the egg-sugar mixture, mixing on low until just combined.

Pour the batter into the prepared pan and smooth the top evenly with a spatula.

Bake for 20 to 25 minutes or until a toothpick inserted comes out clean and the surface is lightly golden.

Let the cake cool in the pan for 10 minutes before transferring to a wire rack to cool completely.

Spread a layer of cream cheese filling evenly over the cooled cake surface using a spatula.

Starting from one end, roll the cake tightly into a spiral, keeping the filling inside.

Slice the rolled cake into 1-inch thick rolls and arrange on a platter. Drizzle with chocolate sauce before serving.
