A jelly roll that has a filling of "manjar" (a confection made by cooking condensed milk in the top of a double boiler until it is thick and caramel-colored). This roll is called "brazo de reina" (arm of the queen).
- 4 eggs, at room temperature
- 3/4 teaspoon baking powder
- 1 teaspoon salt
- 3/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 3/4 cup sifted cake flour
- Confectioners' sugar
- 1 can of Dulce de Leche or Manjar
Beat the eggs, preferably in an electric mixer, with the baking powder and salt until thick and light-colored, gradually adding three-quarters cup granulated sugar. Add the vanilla and fold in the flour.
Turn into a 15 1/2 by 10 1/2-inch jelly roll pan that has been greased and lined with greased paper. Bake thirteen minutes. Depending on your oven, this may take less time; when you see the edges begin to brown, take it out.
Turn from the pan onto a towel that has been dusted with confectioners' sugar. Quickly remove the paper and cut off the crisp edges of the cake. Roll, jelly-roll fashion, with the towel inside and enwrapping the cake. Chill.
Unroll the cake and spread with the Dulce de Leche or Manjar. Roll jelly-roll fashion again, sprinkle with confectioner's sugar and refrigerate until ready
