Spiced sticky toffee sandwich cake

Step by Step

Step 1

Preheat the oven to 180˚C, gas mark 4. Boil the kettle. Grease and line the bases of 2 x 20cm loose-based cake tins. Put the dates in a heatproof bowl. Stir in the cinnamon, mixed spice, bicarbonate of soda and a pinch of sea salt, then cover with 200ml just-boiled water and set aside for 5 minutes.

Step 2

Pour the softened dates and water into a blender (or use a stick blender) and whizz to a smooth purée, adding a couple of extra tablespoons of water if needed. In a large mixing bowl, use electric beaters (or a freestanding mixer) to beat together 180g butter with the light brown soft sugar, until pale and creamy. Beat in the eggs one at a time, then stir in the flour, vanilla and puréed dates. When smooth, divide the mixture between the tins and bake for 35-45 minutes, until a skewer inserted comes out clean.

Step 3

Leave the cakes in the tins for 10 minutes, then turn out dome-side up onto a cooling rack. Spread the top of one of the warm cakes with 2 tbsp dulce de leche – this will be the top cake – then let them cool completely.

Step 4

Once cooled, make the filling. Use electric beaters to beat the remaining 100g butter with the soft cheese and icing sugar for 3-4 minutes, until you have a smooth and creamy buttercream. Mix in 2 tbsp dulce de leche. Put the untopped cake on a board or stand and spread over the buttercream. Drizzle or dollop over the remaining 2 tbsp dulce de leche, swirling it around so it drizzles down the side a little too, then top with the other cake.
