Now for the fun part—let’s create some magic!

1. Preheat your oven to 350°F. Line a 15×10-inch jelly-roll pan with parchment paper and lightly grease it.
2. In a bowl, sift together the flour, cocoa powder, baking powder, and salt. Set aside.
3. In a large bowl, beat the egg whites with an electric mixer until soft peaks form. Gradually add 1/4 cup of granulated sugar, beating until stiff peaks form.
4. In another bowl, beat the egg yolks with the remaining sugar and vanilla extract until thick and pale. Gently fold in the flour mixture.
5. Carefully fold the egg white mixture into the yolk mixture, ensuring not to deflate the batter.
6. Spread the batter evenly in the prepared pan, smoothing the top. Bake for 12-15 minutes or until the cake springs back when touched.
7. While the cake bakes, prepare a clean kitchen towel and dust it with powdered sugar.
8. Once baked, immediately invert the cake onto the prepared towel. Peel off the parchment paper and roll the cake up in the towel, starting at a short end. Let it cool completely.
9. For the filling: In a saucepan, combine the coconut, pecans, evaporated milk, sugar, butter, and vanilla. Cook over medium heat until thickened, about 10 minutes. Let cool.
10. Unroll the cake carefully, spread the filling evenly, and roll it back up. Dust the top with more powdered sugar before serving.
