BLACKBERRY ICEBOX CAKE

Steps:

• Measure out 2 cups blackberries from 2 pints. Slice berries in half lengthwise and transfer to a medium bowl. (Save remaining berries for decorating later.)
• Add 1/2 cup blackberry jam to bowl with sliced berries. Using a citrus juicer, juice 1 lemon over berry mixture. Let sit 10 minutes.
• Using an electric mixer, beat 2 cups heavy cream in a large bowl, starting on low speed and increasing to high, until soft peaks form.
• Beat in 1/4 cup powdered sugar and a pinch of salt just to combine.
• Line a medium bowl (6-cup capacity) with plastic wrap, pressing into bottom and up sides and leaving plenty of overhang. Line the bottom of bowl with a layer of vanilla wafers.
• Spoon about 1/4 cup berry mixture over wafers. Scoop 1 1/2 cups whipped cream into a small bowl; cover and save in fridge for later. Spread 1/2 cup of the remaining whipped cream evenly over wafer and berry layers. Repeat layers with wafers (breaking to fit as needed-no one will know), blackberry mixture, and whipped cream, using more for each layer as the bowl gets wider, until you run out of all the components.
• Bring up plastic overhang to cover and chill at least 24 hours.
• Unwrap plastic from top of cake and place a large cake stand or platter firmly over it. Flip over and lift bowl away; peel away plastic wrap. (Ta-da!)
• Using a whisk, beat reserved whipped cream back to soft peaks, then use a spoon to dollop cream all over cake and spread around evenly.
• Cut reserved berries in half lengthwise and arrange them on top.
• Slice cake into 8 pieces to serve.
• Do Ahead
• Cake can be assembled 2 days ahead and can also be unmolded and covered in cream 1 hour ahead; either way, keep in the fridge until the last minute.
