Ingredients

Scale
  • About 12 full sheets graham crackers, crushed lightly or broken into pieces
  • 1 cup (8 oz) mascarpone cheese, softened
  • 1 cup (240 ml) heavy cream, cold
  • 1/3 cup (40 g) powdered sugar
  • Zest of 2 medium lemons
  • 2 tablespoons (30 ml) freshly squeezed lemon juice
  • 1 1/2 cups (225 g) blueberries, fresh or frozen (thawed and drained if frozen)
  • 1 teaspoon (5 ml) vanilla extract
  • Optional garnishes: fresh mint leaves or extra lemon zest

Instructions

  1. Prepare the Cream Layer (10 minutes): In a medium bowl, beat 1 cup of mascarpone cheese until smooth. In a separate bowl, whip 1 cup (240 ml) of cold heavy cream with 1/3 cup (40 g) powdered sugar and 1 teaspoon vanilla extract until soft peaks form. Gently fold the whipped cream into the mascarpone until combined and fluffy. Add the zest of 2 lemons and 2 tablespoons (30 ml) lemon juice, folding carefully to incorporate the fresh citrus brightness. Avoid overmixing to keep the texture light and…
  2. Layer the Cake (10-15 minutes): Spread a thin layer of the mascarpone mixture on the bottom of your 9×9-inch pan. Add a layer of graham crackers, breaking them as needed to cover evenly.

  3. Chill Overnight (at least 6 hours): Cover the assembled cake with plastic wrap and refrigerate. This step allows the graham crackers to soak up moisture and soften into cake-like layers. The flavors meld into a harmonious balance. For best results, make this the day before serving.
  4. Serve and Enjoy: Remove from the fridge about 15 minutes before serving to take the chill off slightly. Slice with a sharp knife dipped in hot water to get neat edges. Garnish with fresh mint or extra lemon zest if desired. Handle slices gently to keep layers intact.

Notes

Do not skip the chilling step; at least 6 hours is needed for the graham crackers to soften properly. Use fresh lemon zest and juice for best flavor. If using frozen blueberries, thaw and drain well to avoid soggy layers. Softened mascarpone is key for a smooth cream layer. Fold whipped cream gently into mascarpone to keep the mixture light and airy. For gluten-free, use gluten-free graham crackers. For dairy-free, substitute mascarpone with coconut cream and use dairy-free whipped topping.
