In a small mixing bowl, gently whisk the softened butter and confectioner sugar together.
Then, whisk in the egg whites and flour. Mix until combined.
Transfer your batter to a piping bag then, design your Spider + Spider Web directly onto your Flexiflat™. Place it in the Freezer for about 20minutes while preparing the batter for your roll.
BLACK VELVET CAKE BATTER
Preheat oven to 350F/180C.
Whip the egg whites (3 + 1/4 cup) until stiff peaks. Add the Sea Salt half way. Set aside.
In a mixing bowl, beat the egg yolks with the sugar until light and fluffy, on medium high speed for about 6 minutes.
Then, add the Flour, Black Cocoa Powder, milk, mixing about 3-4 tablespoons of whipped egg whites to loosen the batter.
Gently fold the remaining egg white into your Chocolate batter.
Take your Flexiflat™ out of the freezer and pour your black velvet batter on top. Evenly spread with your offset spatula.
Bake for 18 minutes at 350F/180C. (Every oven heats differently, monitor your chocolate cake from 15min). It is ready when the toothpick inserted comes out clean.
As soon as your Black Velvet Cake is out of the oven, trace your offset spatula around and flip it over your Small bonMAT™. Then, flip it back onto your Square bonMAT™ and gently roll it. Set aside.
While your roll is cooling down, prepare your Cream Cheese Frosting.
BLACK VELVET CREAM CHEESE FROSTING
In your mixing bowl, beat the softened butter and cream cheese together until creamy.
Add the vanilla paste and sea salt. Stir until combined.
Gradually add the confectioners sugar.
Then, add the black cocoa powder together with the heavy whipping cream. Mix until completely combined.
Transfer your Frosting to a piping bag with the star tip on.
ASSEMBLY
Gently unroll your cake, pipe your frosting all over and use your off set spatula to even it out. Then re-roll, cover with a plastic wrap and let it set in the refrigerator two hours minimum (Overnight is always best).
Once ready, slice your roll and serve with whipped cream and/or Vanilla Ice cream. Enjoy, Bon Appétit and Happy Halloween!
