Jelly Slice


  • 1 1/2 cups crushed biscuits (digestives, graham crackers, or plain cookies work well)
  • 1/4 cup unsalted butter, melted

For the Creamy Layer:

  • 1 cup cream cheese, softened (or use mascarpone for extra richness)
  • 1/2 cup powdered sugar
  • 1 teaspoon vanilla extract
  • Optional: 1/2 cup whipped cream for a lighter texture

For the Jelly Layer:

  • 1 cup boiling water
  • 1 packet (about 2 tablespoons) powdered gelatin or jelly crystals (your choice of flavor)
  • Optional: 1–2 tablespoons fresh fruit juice or liqueur for added flavor

Step-by-Step Instructions

1. Make the Base

  1. In a mixing bowl, combine the crushed biscuits and melted butter until the mixture resembles wet sand.
  2. Press the mixture firmly into the base of a lined 8x8-inch square baking pan.
  3. Chill the base in the refrigerator while you prepare the next layers.

2. Prepare the Creamy Layer

  1. In a large bowl, beat the softened cream cheese, powdered sugar, and vanilla extract until smooth and creamy.
  2. If using whipped cream, gently fold it into the cream cheese mixture for a lighter texture.
  3. Spread the creamy mixture evenly over the chilled biscuit base.
  4. Return the pan to the refrigerator while you prepare the jelly layer.

3. Make the Jelly Layer

  1. In a heatproof bowl, dissolve the gelatin or jelly crystals in boiling water, stirring until completely smooth.
  2. If desired, stir in fresh fruit juice or liqueur for extra flavor.
  3. Allow the jelly mixture to cool slightly but not set (about 5–10 minutes).

4. Assemble the Slice

  1. Pour the cooled jelly mixture over the creamy layer, spreading it gently to ensure an even top.
  2. Tap the pan lightly on the counter to remove any air bubbles.

5. Chill Until Set

  1. Refrigerate the slice for at least 4–6 hours, or until the jelly layer is fully set and firm.
  2. Once set, use the parchment paper to lift the slice out of the pan and transfer it to a cutting board.

6. Serve & Enjoy

  1. Cut the slice into squares or rectangles using a sharp knife. Dip the knife in hot water and wipe it clean between cuts for clean edges.
  2. Serve chilled and enjoy the delightful combination of textures and flavors!

Tips for Success

  • Choose Your Jelly Wisely: Opt for bold, fruity flavors like raspberry, strawberry, lime, or tropical mixes for a vibrant pop of color and taste.
  • Add Fresh Fruit: Top the slice with fresh berries or citrus zest for an extra touch of freshness.
  • Make It Ahead: This dessert can be made a day in advance and stored in the fridge until ready to serve.
  • Experiment with Layers: Swap the creamy layer for custard, yogurt, or even a layer of whipped cream for variety.
  • Double the Recipe: This slice disappears quickly, so make a larger batch for bigger gatherings.
