Description

This giant homemade wagon wheel biscuit features buttery cookies layered with raspberry jam and fluffy marshmallow, all coated in rich dark chocolate. A nostalgic dessert that is fun to share and irresistibly indulgent.


Ingredients

  • 113 g unsalted butter, softened (1/2 cup / 1 stick)
  • 200 g white granulated sugar (1 cup / 7 oz)
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 295 g plain flour (all purpose flour) (2 1/4 cups / 10 1/2 oz)
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1/2 cup raspberry jam
  • 270 g vanilla marshmallows (9 1/2 oz)
  • 400 g dark chocolate (50% cocoa solids) (14 oz)

Instructions

  1. Preheat the oven to 180°C (160°C fan forced) / 350°F. Prepare 2 baking sheets at least 9 inches wide.
  2. In a stand mixer fitted with the paddle attachment, cream together the butter and sugar on medium speed until pale and fluffy.
  3. Add the egg and vanilla extract and beat until fully combined.
  4. Add the flour, baking powder, and salt. Mix on low speed until the dough just comes together with no visible streaks of flour.
  5. Shape the dough into a disk and divide it in half. Place one half between two sheets of baking paper and roll into a 5 mm thick circle.
  6. Use a 9-inch round springform pan ring as a cutter to shape the dough into a neat circle. Trim any rough edges with a sharp knife.
  7. Transfer the dough circle to a baking tray using the baking paper. Repeat with the remaining dough.
  8. Bake for 10 to 12 minutes or until lightly golden around the edges. Cool completely before assembling.
  9. Spread half of the raspberry jam over each biscuit layer.
  10. Lightly grease a microwave-safe bowl and add the marshmallows. Microwave on high for 35 to 45 seconds until puffed and soft.
  11. Stir the marshmallow until smooth, then quickly spread it over one biscuit layer, stopping just short of the edges.
  12. Chill for 5 minutes to firm the marshmallow slightly. Place the second biscuit on top with the jam side facing down.
  13. Freeze the assembled biscuit for 10 minutes while preparing the chocolate coating.
  14. Melt the dark chocolate in 30-second microwave intervals, stirring between each until smooth.
  15. Line a large plate or tray with baking paper. Spread one-third of the melted chocolate into a circle slightly larger than 9 inches and place the biscuit stack on top.
  16. Pour the remaining chocolate over the top and sides, smoothing it evenly to coat completely.
  17. Refrigerate until the chocolate is fully set, then slice into squares or fingers and serve.

Notes

  • Use high-quality dark chocolate for the best flavor and texture.
  • Chilling the biscuit before coating helps prevent cracking and keeps the layers stable.
  • Store in an airtight container in the refrigerator for up to 5 days.
  • For a softer texture, let slices sit at room temperature for 10 minutes before serving.
