# What You Need:
→ Sponge Cake
01 - 4 large eggs, separated
02 - 3/4 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 using an electric mixer until the mixture becomes 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, approximately 4-5 minutes.
04 - Gently fold the whipped egg whites into the yolk mixture using a spatula, then sift in the flour and fold until just combined, being careful not to deflate the mixture.
05 - Pour the 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 up tightly with the towel from the short end and allow to cool completely at room temperature.
07 - In a small saucepan over low heat, gently melt guava paste with water, stirring occasionally until smooth and spreadable. Allow to cool to room temperature.
08 - Unroll the cooled cake and spread the guava filling evenly over the entire surface using an offset spatula.
09 - Roll up the cake tightly without the towel. Transfer seam side down to a serving platter.
10 - In a clean bowl, beat egg whites using an electric mixer until soft peaks form. Gradually add sugar while continuing to beat until stiff, glossy peaks form, approximately 5-6 minutes.
11 - Spread or pipe the meringue over the top and sides of the rolled cake using an offset spatula or piping bag.
12 - Using a kitchen torch, carefully brown the meringue until golden, or place under a preheated broiler for 1-2 minutes, watching closely to prevent burning.
13 - Refrigerate for at least 30 minutes before slicing with a sharp knife. Serve chilled.
