CHOCOLATE - PEANUT BUTTER MOUSSE CAKE

Steps:

• For peanut butter mousse: Line 6-cup loaf pan with foil.
• Mix together 1 cup sugar, peanut butter and cream cheese in a large bowl until smooth.
• Mix in cream.
• Beat egg whites in medium bowl until soft peaks form.
• Gradually add remaining 2/3 cup sugar and beat until stiff and shiny.
• Fold whites into peanut butter mixture in 2 additions.
• Tilt prepared pan lengthwise at 45 degree angle (do this by placing one long edge of loaf pan on top of a couple of custard cups).
• Spoon in peanut butter mousse and smooth top (the mousse will form a triangle down the length of the pan – with half the pan empty).
• Set pan in freezer, propping to hold angle.
• Freeze until mousse is firm, about 1 hour.
• For chocolate mousse: Heat cream and sugar in heavy small pan over very low heat, stirring just until sugar dissolves.
• Transfer to medium bowl and refrigerate until well chilled.
• Meanwhile, melt chocolate in top of double boiler over simmering water, stirring until smooth.
• Cool 5 minutes.
• Dissolve espresso powder in hot water in small bowl.
• Whisk in yolks.
• Add mixture to warm chocolate and stir until mixture is smooth and slightly thickened.
• Let stand until batter is cooled to room temperature, but not set.
• Beat chilled cream to soft peaks.
• Fold cream into chocolate mixture in 2 additions.
• Set pan with frozen peanut butter mousse flat onto work surface.
• Spoon chocolate mousse over peanut butter mousse (this will fill the empty half-triangle).
• Smooth top.
• Cover pan.
• Freeze until chocolate is firm, about 6 hours or overnight.
• For glaze: Heat cream and butter in medium saucepan over low heat until cream simmers and butter is melted.
• Turn off heat.
• Add chocolate and whisk until mixture is smooth.
• Let cool until thickened but still of pouring consistency, about 1 ½ hours.
• Invert loaf onto cake rack.
• Remove pan; remove and discard foil.
• Pour glaze over mousse and smooth all surfaces.
• Transfer mousse to a serving platter.
• Freeze until glaze sets, about 1 hour (can be prepared 1 day ahead. Wrap loosely when chocolate is frozen solid).
• Cut mousse into ½ inch thick slices.
• Garnish with berries and mint.
