Yields 1 log cake

Cake batter
5 eggs
2/3 cup sugar
1 tsp vanilla extract
2/3 cup flour
1/4 cup cocoa

  1. Preheat the oven to 375F.
  2. Combine the flour and cocoa powder in a small bowl and set aside. It's important that there's no lump in your flour, use a sieve if needed.
  3. Separate egg whites from the yolks.
  4. In a small bowl, beat the egg whites with an electric mixer to form stiff peaks. Gradually incorporate 1/3 cup of sugar. Set aside.
  5. In a medium size bowl, beat the egg yolks with an electric mixer for 5-6 minutes or until you get a pale yellow and fluffy texture. Incorporate 1/3 cup of sugar.
  6. Add a third of the egg white mixture into the egg yolks gently by folding in with a spatula. Repeat with two more additions. Do not overwork.
  7. Sprinkle small amounts of flour on top of the egg mixture and gently fold in with a spatula. Repeat until all the flour has been incorporated.
  8. Cut off a parchment paper and place at the bottom of a sheet pan. Lightly coat the sides with butter and flour.
  9. Pour the cake batter onto the sheet pan. Bake for 6-8 minutes. Be careful to not over-bake as your cake will be dry.
  10. Lay a clean kitchen linen on your countertop and sprinkle a little bit powdered sugar on it.
  11. Put the warm cake on the kitten linen, peel off the parchment paper and roll the cake into a tight spiral. Let cool down in the linen until it gets to room temperature.
