Blackberry Icebox Cake

From the kitchen of Carly

No-bake layers of crispy vanilla wafers, tart blackberry jam, and whipped cream that tastes like summer in a slice. Lemon juice brightens the berries while the wafers soften into tender crumbs. Chill overnight; the magic happens while you sleep.

Blackberry Icebox Cake

Blackberries macerated in lemon and jam soak into layers of vanilla wafers and whipped cream, softening them into something between cake and custard. Twenty-four hours of chill time does the real work here, turning the whole thing into a silky, spoonable dessert that feels like you fussed but didn't really. No oven required, just a bowl and patience.

Ingredients

4 servings

  • 2 pintblackberries, divided
  • 1/2 cupblackberry jam
  • 1lemon
  • 2 cupchilled heavy cream
  • 1/4 cuppowdered sugar
  • 1 pinchkosher salt
  • 8 oz. vanilla wafers
  • 1divided

Instructions

  1. From the 2 pints of blackberries, measure out 2 cups and slice each one in half lengthwise. Transfer them to a medium bowl and set the remaining berries aside for decorating.

  2. Pour in the 1/2 cup of blackberry jam, then juice the lemon directly over the berry mixture. Let everything sit for 10 minutes so the flavors meld.

  3. Pour 2 cups of chilled heavy cream into a large bowl and beat with an electric mixer, starting on low speed and working up to high, until soft peaks form.

  4. Add the 1/4 cup of powdered sugar and a pinch of salt, beating just long enough to combine.

  5. Line a medium 6-cup bowl with plastic wrap, pressing it firmly into the bottom and up the sides with plenty of overhang to spare. Lay down a single layer of vanilla wafers across the bottom.

  6. Spoon about 1/4 cup of the berry mixture over the wafers. Transfer 1 1/2 cups of the whipped cream to a small bowl, cover it, and stash it in the fridge for later. Spread 1/2 cup of the remaining whipped cream evenly over the wafer and berry layers. Continue building layers of wafers (break them to fit as needed), blackberry mixture, and whipped cream, using progressively more cream per layer as the bowl widens, until all the components are used up.

  7. Fold the plastic overhang up and over the top to cover, then refrigerate for at least 24 hours.

  8. Unwrap the plastic from the top and set a large cake stand or platter firmly over the bowl. Flip the whole thing over in one confident motion, then lift the bowl away and peel off the plastic wrap.

  9. Whisk the reserved whipped cream back to soft peaks, then spoon it over the surface of the cake, spreading it around to cover evenly.

  10. Halve the reserved berries lengthwise and arrange them across the top of the cake.

  11. Cut into 8 pieces and serve.

  12. The cake can be assembled up to 2 days ahead; once unmolded and topped with cream, it holds for up to 1 hour before serving. Keep it in the fridge right up until the last minute either way.

Tips from the kitchen

  • Save at least one cup of whipped cream before you layer, keep it chilled, and re-whip it just before serving so you have fresh, voluminous dollops for the top instead of tired cream that's been sitting around.
  • Don't be precious about breaking the wafers to fit the bowl as you layer. They're going soft anyway, and nobody sees the inside.
  • The lemon juice on the berries is doing heavy lifting. Don't skip it or reduce it. It cuts the jam's sweetness and keeps the whole thing from tasting cloying.

Variations

  • Raspberry icebox cake: swap 2 pints raspberries and 1/2 cup raspberry jam for the blackberries and blackberry jam. Treat the berries the same way.
  • Mixed berry with orange: use 1 pint blackberries and 1 pint blueberries, juice an orange instead of lemon, and use apricot jam if you have it. The orange is brighter and less sharp than lemon.
  • Crushed amaretti swap: replace vanilla wafers with crushed amaretti cookies for almond flavor and a slightly different texture that absorbs the berry juice differently.
  • No-berry version: fold 1 cup crushed raspberries or strawberries into the final layer of whipped cream instead of using jam, layer only with wafers and plain whipped cream, and top with fresh berries for a lighter, more delicate cake.

Make ahead and storage

Covered and chilled in the bowl, this keeps for 2 days, though the wafers soften more each day (which some people love, others find too mushy). Don't freeze it. The texture relies on that specific firmness from the chilled cream.
