In a large mixing bowl, put the 6 egg yolks and beat until they are light and pale
Add the sweetener gradually and beat until the mixture is light and creamy
Add the cocoa powder and extracts and mix well
In a separate mixing bowl, whip the egg whites to a stiff peak
Fold the egg whites into the chocolate mixture 1/3 at a time
Once it is all incorporated, spread mixture onto a jelly pan (1/2 baking sheet) lined with parchment paper
Bake at 350 F for 20 minutes or until a toothpick comes out clean
Remove the cake from the oven and cover with aluminum foil
Let cool 1/2 to 1 hour but the cake still needs to me warm in order to roll without cracking
Flip the cake over onto parchment paper so the bottom is now the top
Top the cake with Keto Italian Meringue (http://ketonaturopath.com/keto-italian-meringue/) You can alternatively use plain meringue or whipped cream
Roll the cake up lengthwise to form the Swiss Roll
Refrigerate for at least 1 hour
Slice and enjoy!
