Sticky Date and Walnut Cake with Maple Syrup Icing

This is a recipe from the Waitrose website that we printed out a L-O-N-G time ago.  Finally, today, we got around to making it.

Ingredients used were -
250g dates, chopped
150g butter, softened
100g soft brown sugar
4 Tbsp (60ml) maple syrup
250g Plain flour (we used Dove's farm gluten free)
2 eggs, beaten
1½ tsp baking powder (we used Dr Oetker gluten free)
1½ tsp mixed spice
50g walnuts, chopped
125g icing sugar, sifted

Having chopped the dates, they were placed in a bowl and covered with 150ml boiling water.  Whilst they were soaking, we prepared the rest of the ingredients and preheated the oven to 170C (fan).

The butter and brown sugar were beaten together until creamy.  Half of the maple syrup was added and mixed through.  Then, the flour and eggs were added a little at a time and fully incorporated.

After this, the mixed spice and baking powder was added and stirred through thoroughly.  Once this was done, we added the dates (and the soaking water) and two thirds of the chopped walnuts.  Again, the mix was thoroughly stirred.

The mix was then shared between metal baking tins which had been well greased.  A traybake tin, about 25cmx17cm, and a small loaf tin (10cmx7cm) were used. 

These were then baked in the pre-heated oven for 40 minutes when they were tested using a knife to see if they were cooked through.  Once the knife came out clean, the tins were placed on a cooling tray and, after about 10 minutes, the cakes were removed and left to cool fully.

Whilst the cakes cooled, the icing was made by mixing the icing sugar, remainder of the maple syrup and a small amount of warm water to get a runny mix.  This was then drizzled over the cakes and the remaining chopped walnuts were sprinkled on top.
