# What You'll Need:
→ Sponge Cake
01 - 4 large eggs, separated
02 - 9/16 cup granulated sugar, divided
03 - 1 teaspoon vanilla extract
04 - 1 cup all-purpose flour
05 - 1/4 teaspoon salt
→ Filling
06 - 8 ounces guava paste
07 - 2 tablespoons water
→ Meringue Topping
08 - 3 large egg whites
09 - 1/2 cup granulated sugar
10 - 1/2 teaspoon cream of tartar
# How To Make It:
01 - Preheat oven to 350°F. Line a 10x15 inch jelly roll pan with parchment paper and lightly grease the surface.
02 - In a large bowl, beat egg yolks with half the sugar and vanilla extract until pale and thick, approximately 3-4 minutes.
03 - In a separate clean bowl, whisk egg whites with remaining sugar, salt, and cream of tartar until stiff peaks form.
04 - Gently fold the whipped egg whites into the yolk mixture. Sift in the flour and fold just until combined, being careful not to deflate the mixture.
05 - Pour batter into the prepared pan and spread evenly. Bake for 12-15 minutes, or until the cake springs back when lightly touched.
06 - While still warm, invert the cake onto a clean kitchen towel dusted with sugar. Carefully peel off the parchment paper. Roll the cake tightly with the towel from the short end and allow to cool completely.
07 - In a small saucepan over low heat, gently melt guava paste with water, stirring until smooth. Allow to cool to room temperature.
08 - Unroll the cooled cake and spread the guava filling evenly across the surface.
09 - Roll up the cake tightly without the towel. Transfer to a serving platter with seam side down.
10 - Beat egg whites in a clean bowl until soft peaks form. Gradually add sugar and continue beating until stiff, glossy peaks form.
11 - Spread or pipe the meringue over the top and sides of the rolled cake.
12 - Using a kitchen torch, carefully torch the meringue for a golden finish, or briefly place under a hot broiler while watching closely to prevent burning.
13 - Refrigerate for at least 30 minutes before slicing. Serve chilled.
