Best Mango Mousse Cake

Directions

Make sponge cake:

Preheat oven to 350℉ (180℃). Lightly butter bottom and side of a 10-inch springform cake pan. Line bottom of the pan with a circle of baking parchment or waxed paper. Dust side of the pan with flour and tap out excess.

In a small bowl, whisk together flour, baking powder andamp; salt.

Sift flour mixture onto a piece of waxed paper. In a large bowl, using a hand-held electric mixer set at high speed, beat egg yolks and 2 tablespoons of granulated sugar for 4 to 6 minutes, until batter is pale yellow and forms a thick ribbon.

Beat in vanilla. Beat egg whites at low speed until frothy. Gradually increase speed to high and continue beating soft peaks start to form.

One teaspoons at a time, gradually add remaining 2 tablespoons of sugar and continue beating whites until they form stiff, shiny peaks. Scrape ⅓ of whites on top of beaten egg yolks.

Resift ⅓ of flour mixture over whites andamp; fold flour mixture and egg whites into egg yolk mixture, making sure to free any flour that may be clinging to side of the bowl.

One-third at a time, gently fold in remaining whites with ⅓ of resifted flour mixture. Do not overfold.

Scrape batter into prepared pan. Bake cake for 8 to 12 minutes, until center springs back when gently touched.

Cool cake in pan on a wire rack for 5 minutes. Remove from pan andamp; cool completely.

Make the mango mousse:

Put water in a small heatproof cup. Sprinkle gelatin over water and let stand for 5 minutes to soften.

Place cup with softened gelatin in a saucepan with enough water to come halfway up side of cup.

Heat gelatin mixture in hot, not simmering water. Stir gelatin mixture frequently for 2 to 3 minutes, until gelatin granules dissolve completely and mixture is clear.

Remove pan from heat. Leave cup containing gelatin mixture in hot water to keep gelatin warm until ready to use.

Peel mangos and cut fruit away from pit Cut fruit into large chunks. Combine half of mango chunks with ½ cup of sugar in bowl of a food processor.

Process mangos for 40 to 60 seconds, until pureed. Transfer puréed mangos to a large sauce pan. Repeat with remaining mangos and ½ cup of sugar.

Cook the mango mixture over medium-low heat, stirring constantly until warm. Remove saucepan from the heat. Add the gelatin mixture and vanilla and whisk until blended. Transfer mango mixture to a large bowl and cool to room temperature.

In a chilled large bowl, beat the heavy cream and sour cream until mixture forms soft peaks. Fold ⅓ of whipped cream into mango mixture to lighten it. Fold in remaining whipped cream.

Assemble cake:
