In a medium saucepan, combine the pitted and chopped dates, dairy-free milk, and bicarbonate of baking soda. Bring to a boil over medium heat, stirring occasionally for about 5 minutes until the dates soften. Remove from heat and stir in the smooth Biscoff spread until incorporated. Set aside to cool slightly.
Preheat your oven to 170°C (Gas Mark 3) while greasing a 2-liter pudding mold with vegan butter or oil.
In a large mixing bowl, combine the cooled date mixture with flour, oil, brown or coconut sugar, baking powder, cinnamon, and a pinch of salt. Mix until the batter is smooth and well-combined.
Pour the pudding mixture into the greased mold. Cover tightly with aluminum foil and place it in the preheated oven. Bake for approximately 1 hour and 30 minutes, or until a skewer inserted into the center comes out clean.
Once baked, let the pudding cool in the mold for about 10 minutes. Invert the mold onto a wire rack and allow it to cool completely.
For the Biscoff custard, whisk together dairy-free milk, sugar, and cornflour in a saucepan over medium heat until smooth. Heat while stirring constantly until thickened, then stir in Biscoff spread for flavor.
In a separate saucepan, combine dairy-free cream and sugar for the butterscotch sauce. Simmer over low heat, stirring occasionally until thickened, about 6-8 minutes. Remove from heat.
To serve, slice the cooled pudding and place a slice on each plate. Drizzle with warm butterscotch sauce and top with Biscoff custard. Decorate with gold lustre powder or crushed Biscoff cookies.
Notes
This pudding is best served warm.
