Yield Makes about 8 cups

Number Of Ingredients 7

2/3 cup heavy cream
6 large egg whites
1 2/3 cups sugar
1 3/4 cups (3 1/2 sticks) unsalted butter, cut into pieces, softened
1 teaspoon pure vanilla extract
1/3 cup hazelnut cream
Pinch of salt

Steps:

Put cream into the bowl of an electric mixer fitted with the whisk attachment; beat on medium-high speed until soft peaks form, about 4 minutes. Transfer to a medium bowl. Refrigerate 1 hour.
Whisk egg whites and sugar in the clean bowl of mixer set over a pan of simmering water until sugar has dissolved and mixture registers 160 degrees, 2 to 3 minutes.
Attach bowl to mixer fitted with the clean whisk attachment; beat on high speed until slightly cooled and stiff (but not dry) peaks form, about 5 minutes.
Fit mixer with paddle attachment. With mixer on medium-low speed, add butter, several pieces at a time, mixing well after each addition (meringue will deflate slightly as butter is added). Add vanilla, hazelnut cream, and salt; mix until mixture comes together, 3 to 5 minutes. Fold in whipped cream with a rubber spatula. Use immediately.
