FOR THE CAKE: Begin early in day or day ahead to make Cannoli Cake.
 
Preheat oven to 375°F 
In small bowl, with mixer at high speed, beat egg whites until soft 
peaks form; gradually sprinkle in 1/2 cup sugar, beating until sugar 
completely dissolves and whites stand in stiff peaks.
 
In large bowl, using 
same beaters and with mixer at low speed, beat egg yolks, flour, baking 
powder, salt, remaining 1/2 cup sugar, and 1 teaspoon vanilla, and 2 
Tablespoons water until blended. With rubber spatula, gently fold beaten
 egg whites into egg-yolk mixture, one-third at a time.
 
Spoon batter into 
UNGREASED 10 inch by 3 inch springform pan. Bake 30 to 35 minutes until 
cake is golden and top springs back when lightly touched.
 
Invert cake in pan on wire rack; cool completely in pan.
 
FOR BRUSHING CAKE 
LAYERS: From oranges, grate 2 teaspoons peel (use the rest of peel for 
the filling) and squeeze 1/3 cup juice (IF NOT USING LIQUEUR, INCREASE 
JUICE TO 1/2 CUP). Stir liqueur into 1/3 cup juice; set aside.
 
FOR THE FILLING: In 
large bowl, with mixer at low speed, beat ricotta, cream cheese, rest of
 the grated orange peel, confectioners’ sugar and 1 teaspoon vanilla 
extract until smooth. Stir in 1/4 cup semisweet-chocolate mini pieces.
 
With metal spatula, 
loosen cake from edge of pan; remove pan side. Loosen cake from pan 
bottom; remove pan bottom. With serrated knife, cut cake horizontally 
into 2 layers. Brush orange-juice mixture evenly over cut side of both 
layers.
 
Place bottom cake 
layer, cut-side up, on cake plate. Spoon ricotta-cheese filling on 
center of cake layer. Spread some filling out to edge, leaving a center 
rounded to achieve a dome effect.
 
Cut a small wedge out 
of remaining cake layer; and gently rest cake layer over filling. 
(Cutting wedge will allow cake layer to bend, without cracking, to fit 
over dome shape.).
 
PREPARE VANILLA-CREAM 
FROSTING: In small bowl, with mixer at medium speed, beat 3 Tablespoons 
margarine or butter, softened, 3 Tablespoons milk, 1 3/4 cups 
confectioners’ sugar, and 3/4 teaspoon vanilla extract until smooth, 
adding more milk if necessary until mixture has an easy spreading 
consistency. In large bowl, using same beaters and with mixer at medium 
speed, beat 2 cups heavy or whipping cream until stiff peaks form; fold 
confectioners’-sugar mixture into whipped cream. Spread over top and 
down side of cake.
 
In a heavy small saucepan over low heat, heat remaining 1/3 cup mini pieces, stirring frequently, until melted and smooth.
 
Into waxed-paper cone,
 spoon melted chocolate. (Or, use small decorating bag with small 
writing tube.) With chocolate, make feather design.
 
Refrigerate cake until filling is firm for easier cutting, about 3 hours.
 
TO MAKE WAXED-PAPER 
CONE: Cut square of waxed paper; fold in half into triangle. Lay 
triangle on flat surface so wide side is at top. Fold left-hand corner 
down to center point. Take right-hand corner; wrap it completely around 
folded left-hand corner, forming cone. Both corners meet at center point
 of original triangle. Fold in these ends twice to hold together. Fill 
cone two thirds full; fold top over.
 
MAKING FEATHER DESIGN:
 Piping circles on Cake: Using paper cone with tip cup to make 1/8 inch 
diameter hole, pipe melted chocolate on top of cake in concentric 
circles, starting in center and moving to edge of cake. Start with small
 circle in the middle of cake and go around each circle to the edge. 
This should be 6 circles.
 
Drawing spokes towards
 center: Before chocolate hardens, quickly with tip of toothpick or 
small knife, draw lines in spoke fashion, about 1 1/2 inches apart 
around edge of cake; alternate direction of each spoke, first from edge 
to center of cake, then from center to edge.
 
Completing feather 
design: Continue around top of cake, alternating direction of each spoke
 to make attractive feather design. 16 servings.
