Bolo de Rolo

Ingredients
1/2 lb (250 gr.) unsalted butter, softened
6 oz guava jelly (can substitute other jellies or jams)
6 whole eggs
1/2 lb. (250 gr.) cake flour
1/3 lb. (200 gr.) sugar
granulated sugar for dusting cakes
2 tbsp water or white wine for diluting the jam
 

Using a whisk or egg beater, beat the sugar and butter together in a large bowl until you have a light, fluffy cream. Add the eggs, one by one, making sure that the yolks are skinless, beating the mixture after the addition of each egg. Using a silicone spoon, add the cake flour in small quantities, gently folding in each addition until you have a fine, light batter. Reserve.

In a small saucepan, break up the jam or jelly with a fork, then place over low heat. Add the water or wine and heat, stirring continuously, until the mixture is melted. Reserve.

Grease the three cake pans (see above) generously with unsalted butter and dust with cake flour. Using a wooden spoon spread 6 spoonfuls of the cake batter in each pan - one spoonful in each corner, and two in the middle of the pan. Using a silicone spatula, spread out the batter to cover the entire pan with a thin layer of batter.

One at a time, cook each cake in a preheated 350F degree oven for approximately 10 minutes. The cake must not color. Check for doneness by touching the surface of the cake with a fingertip. If the cake is firm, remove from oven, and turn the cake out onto a new or clean kitchen towel that has been generously dusted with granulated sugar. Repeat this process for the two remaining cakes.

Trim the edges of each cake to make them even. Spread a very thin layer of the jam or jelly across the entire surface of each of the three cakes, reaching all the way to the edges.

Using the kitchen towel to aid, roll the first cake into a tight roll, rolling from the shorter side of the rectangle. Carefully place the roll at the end of the second cake, and roll the second cake onto the first, starting where the first roll ended. Do the same with the third cake, rolling all three together tightly. Wrap the completed bolo de rolo in plastic wrap and reserve.

Wash and regrease the three cake pans, and repeat the spreading of 6 spoonfuls of batter in each pan. Bake each for approximately 10 minutes as before. Turn out onto the kitchen towels, having redusted them with sugar. Repeat the spreading of jam or jelly on the three new cakes. Remove the bolo de rolo from the plastic wrap, and continue to roll and construct the log. One you have a roll of all six cakes rolled together, place the finished product in plastic wrap, place in refrigerator until firm.

To serve, slice the roll across the layers into thin slices, place two slices on each plate, and top with whipped cream if desired.
