Orange Vanilla Cake Roll

Vanilla Filling:
16 ounces cream cheese, room temperature
1/2 cup granulated sugar
2 large eggs, room temperature
1 tablespoon milk
2 teaspoons vanilla extract

Orange Cake:
5 large eggs, room temperature
2/3 cup granulated sugar
1 tablespoon grated orange peel
1 teaspoon vanilla extract
1 cup all-purpose flour
2 tablespoons unsalted butter, melted
1/3 cup confectioners' sugar
Candied citrus slices for garnish

Heat oven to 375 degrees F. Lightly grease bottom of a 15 x 10-inch jellyroll pan. Line with wax paper, then grease paper.

Prepare filling: Beat cream cheese and sugar just until smooth. Beat in eggs, milk and vanilla extract just until blended. DO NOT OVERBEAT. Spread in pan evenly.

Prepare Cake: Beat eggs, sugar, orange peel and vanilla extract at least 12 minutes until very thick, pale and at least tripled in volume (this is very important as the eggs are the only leavening used in this cake). Sprinkle with flour; fold until just blended. Spread evenly over filling. Bake for 19 to 21 minutes or until cake springs back when touched in center.

While cake is baking, sift confectioners' sugar over an area on a clean dish towel the size of the cake. Invert cake onto towel; remove pan and peel off wax paper. Roll up, starting at narrow end, using towel to help. Cool completely on a wire rack.

When ready to serve, garnish with candied citrus slices. Cake can be wrapped and refrigerated up to one week before serving.
