  • 1 can (14 oz) sweetened condensed milk
  • 4 large egg yolks
  • ½ tsp vanilla bean paste

For the Graham Cracker Crumble:

Step 1: Prepare the Key Lime Custard

A tangy yet creamy custard forms the heart of this trifle.

Ingredients Used in This Step:

Key lime juice, zest, condensed milk, egg yolks, vanilla

Method:

  1. In a bowl, whisk together egg yolks and condensed milk until smooth.
  2. Slowly add key lime juice and zest, whisking continuously to prevent curdling.
  3. Mix in vanilla bean paste for enhanced flavor.
  4. Pour into a heatproof dish and bake at 325°F (163°C) for 12–15 minutes, until set but slightly wobbly.
  5. Let cool, then refrigerate for at least 1 hour before assembling the trifle.

💡 Pro Tip: Baking the custard low and slow ensures a velvety-smooth texture without cracks.


Step 2: Make the Graham Cracker Crumble

A buttery, golden crumble provides the perfect contrast to the silky custard.

Ingredients Used in This Step:

Graham cracker crumbs, butter, brown sugar, salt

Method:

  1. Combine graham cracker crumbs, brown sugar, and melted butter in a bowl.
  2. Stir until the mixture resembles wet sand.
  3. Toast in a preheated oven at 350°F (175°C) for 5–7 minutes, until fragrant and lightly golden.
  4. Let cool completely before layering.

💡 Pro Tip: A touch of sea salt enhances the contrast between the tart custard and sweet crumble.


Step 3: Whip the Vanilla Mascarpone Cream

A light and airy mascarpone cream balances the tart lime custard.

Ingredients Used in This Step:

Heavy cream, mascarpone cheese, powdered sugar, vanilla

Method:

  1. In a chilled mixing bowl, whip heavy cream until soft peaks form.
  2. In a separate bowl, whisk mascarpone cheese with powdered sugar and vanilla extract until smooth.
  3. Gently fold whipped cream into the mascarpone mixture, being careful not to deflate it.

💡 Pro Tip: Using mascarpone instead of regular whipped cream adds a luxurious, velvety texture.


Step 4: Assemble the Trifle & Plate with Elegance

Layering the trifle turns a classic pie into a fine-dining dessert.

Ingredients Used in This Step:

Key lime custard, graham cracker crumble, mascarpone cream, garnishes

Method:

  1. Spoon a layer of graham cracker crumble into the base of a clear dessert glass.
  2. Add a generous spoonful of key lime custard, smoothing evenly.
  3. Pipe or spoon a layer of vanilla mascarpone cream for contrast.
  4. Repeat the layering process, finishing with a swirl of mascarpone cream on top.
  5. Garnish with fresh lime zest, a thin key lime slice, and a delicate tuile or white chocolate shard.
  6. Drizzle with a touch of lime-infused syrup for a glossy finish.

💡 Pro Tip: Use a stemmed glass or coupe dish to enhance the refined, layered presentation.
