Ingredients

Scale

Base:

  • 200g digestive biscuits, crushed
  • 100g melted butter

Marshmallow Layer:

  • 200g marshmallows
  • 2 tablespoons milk or cream

Chocolate Topping:

  • 200g dark or milk chocolate
  • 2 tablespoons butter or coconut oil

Optional Variations:

  • Nuts, dried fruits, or sprinkles (for texture and decoration)

Instructions

  1. Prepare Workspace: Clean your workspace and gather all tools including a mixing bowl, saucepan, spatula, and an 8×8 inch baking tin lined with parchment paper for easy removal.
  2. Make the Base Layer: Crush the digestive biscuits into fine crumbs using a food processor or by hand with a rolling pin inside a ziplock bag. Combine the crumbs with melted butter until the mixture resembles wet sand. Firmly press this into the prepared baking tin to form an even layer. Place in the fridge to chill while preparing the next layer.
  3. Prepare Marshmallow Layer: In a saucepan over low heat, melt the marshmallows with the milk or cream, stirring constantly to prevent burning and achieve a smooth, pourable consistency. Pour this mixture evenly over the chilled biscuit base, smoothing the surface with a spatula. Return the tin to the fridge to let the marshmallow set slightly.
  4. Make Chocolate Topping: Melt the chocolate together with butter or coconut oil using a double boiler or microwave, stirring until smooth and glossy. Pour this melted chocolate over the marshmallow layer, spreading it evenly across the surface.
  5. Set the Slice: Refrigerate the assembled slice for at least 2 hours or until the chocolate topping is firm. Once set, cut into squares and optionally decorate with nuts, dried fruits, or sprinkles before serving.

Notes

  • Use your favorite type of biscuits for the base to customize flavor and texture.
  • Ensure marshmallows are melted slowly over low heat to avoid burning and clumping.
  • For a vegan version, use dairy-free marshmallows, plant-based milk, and vegan chocolate.
  • Store the slice in the fridge and consume within 5 days for best freshness.
  • Optional add-ins like nuts or dried fruits can be added between layers or on top for extra crunch and flavor.
