PEANUT DACQUOISE WITH PEANUT BUTTER MOUSSE

Peanut Dacquoise With Peanut Butter Mousse image

I found this on Epicurious. It came from Bon Appetit, April 2011, by Jeanne Kelley... Can be made in two stages. Make the meringue ahead. Very easy, just time consuming. Follow the recipe as written. This was my first time, and look how beautiful. Next time I will drop peanuts over the top. It is as delicious as it looks. ...

Ingredients

MERINGUE LAYERS:
1 1/4 c roasted spanish salted peanuts with skin (6 to 6 1/2 oz) divided
3/4 c sugar, divided
6 large egg whites
1/8 tsp cream of tarter and pinch of coarse kosher salt
MOUSSE:
1/2 c chunky natural-style peanut butter
1/4 c packed golden brown sugar
pinch of coarse kosher salt
1 c chilled heavy whipping cream, divided
1 Tbsp sugar
1 tsp vanilla extract
GLAZE:
1/4 c natural unsweetened cocoa powder
1/4 c sugar
1 c heavy whipping cream
1 1/3` c bittersweet chocolate chips

Steps:

1. For meringue layers: Preheat oven to 275°F. Line large baking sheet with parchment paper. Draw three 10 x 4 1/2-inch rectangles on parchment; turn parchment over. Finely grind 1 cup nuts with 1/4 cup sugar in processor. Coarsely chop remaining 1/4 cup nuts and set aside. Using electric mixer, beat egg whites, cream of tartar, and coarse salt in large bowl until foamy. With mixer running, gradually add remaining 1/2 cup sugar, beating until meringue is stiff and glossy. Add ground nut mixture and coarsely chopped nuts; fold gently just to blend. Spoon 2 cups meringue onto each rectangle on parchment; spread evenly to fill rectangles (any remaining meringue can be baked as cookies). Bake meringues until golden brown all over and dry to touch but still slightly soft, about 1 hour 30 minutes. Transfer to rack and cool completely.
2. For mousse: using electric mixer, beat peanut butter, brown sugar, and coarse salt in medium bowl to blend. With mixer running, gradually beat in 1/4 cup cream. Add another 1/4 cup cream and beat just to blend. Beat remaining 1/2 cup cream, sugar, and vanilla in another medium bowl until peaks form; fold into peanut butter mixture in 3 additions. Chill until ready to use.
3. For glaze: Whisk cocoa powder and sugar in medium saucepan to blend well. Gradually add 1/4 cup water, whisking until smooth. Gradually whisk in heavy cream. Bring to boil over medium heat, whisking frequently. Reduce heat to low. Add chocolate and whisk until melted and smooth. Let stand at room temperature until cool and slightly thickened, stirring occasionally, about 2 hours. Leaving meringues on parchment and using large serrated knife, trim edges of each meringue to original 10 x 4 1/2-inch size. Slide thin knife between meringues and paper to loosen. Spoon 1/4 cup glaze evenly over top of 2 meringue rectangles and spread to cover. Chill until chocolate sets, about 30 minutes. Place 1 glazed meringue rectangle on plate. Spoon half of mousse over (scant 1 1/4 cups); spread out in even layer. Place second glazed meringue rectangle atop first; spread with remaining mousse. Top with unglazed meringue rectangle. Pour 1/2 cup glaze down center of top meringue. Using icing spatula, spread glaze over top meringue, allowing glaze to drip down sides. Smooth top and sides to cover evenly with thin layer. Refrigerate until glaze is set, about 30 minutes. Pour remaining glaze over top of dacquoise and quickly smooth over top and sides in even layer. Sprinkle fleur de sel lightly over top, if desired. Chill at least 3 hours. DO AHEAD: Can be made 3 days ahead. Cover with cake dome and keep chilled.
