Equipment

  • Mixing bowls
  • Electric hand mixer or stand mixer
  • Rubber spatula
  • Shallow dipping bowl
  • 8x8-inch baking dish
  • Offset spatula (optional, for smooth top)

Ingredients

Melon Soak

  • 1/2 cup store-bought melon syrup can be also found online
  • 1/2 cup cold water
  • Melon Mascarpone Cream
  • 8 ounces mascarpone cheese cold
  • 3/4 cup heavy whipping cream cold
  • 3 tablespoons powdered sugar
  • 2 tablespoons store-bought melon syrup
  • 1 pinch salt

Layers

  • 20 to 24 ladyfinger cookies savoiardi

Optional Topping

  • whipped cream
  • melon syrup drizzle
  • white chocolate shavings

Instructions

Make the melon mascarpone cream.

  • In a large bowl, whip the heavy whipping cream and powdered sugar until soft-medium peaks form.

Prepare the mascarpone.

  • In a separate bowl, stir the mascarpone cheese until smooth and creamy.

Combine the cream.

  • Gently fold the whipped cream into the mascarpone until fully combined and fluffy. Fold in the melon syrup and salt. Set aside.

Prepare the melon soak.

  • In a shallow bowl, whisk together the melon syrup and cold water.

Dip the ladyfingers.

  • Quickly dip each ladyfinger into the melon mixture for about 1/2 second per side. Do not soak. The cookies should be lightly moistened but still firm.

Assemble the first layer.

  • Arrange the dipped ladyfingers in a single layer in an 8x8-inch dish.

Add the cream layer.

  • Spread half of the melon mascarpone cream evenly over the ladyfingers.

Add the second layer.

  • Dip remaining ladyfingers and arrange over the cream layer.

Finish the tiramisu.

  • Spread the remaining melon mascarpone cream evenly on top.

Chill.

  • Cover and refrigerate for at least 6 hours or overnight until set.

Notes

  • Use Japanese melon syrup or honeydew syrup for the best melon tiramisu flavor
  • Do not soak the ladyfingers too long or the melon tiramisu may become soggy
  • Dip the cookies quickly so they soften but still hold their structure
  • Chill the melon tiramisu for at least 6 hours for clean slices and best texture
  • Overnight chilling improves the flavor and helps the layers set properly
  • Keep mascarpone cheese cold for a thick and stable melon mascarpone cream
  • If your melon syrup is very sweet, slightly increase the water in the soak
  • For stronger melon flavor, drizzle extra melon syrup between layers
  • This no-bake melon tiramisu tastes best served cold straight from the refrigerator
  • Use an 8x8-inch dish for thick, bakery-style melon tiramisu layers
