Walnut slices

This month challenge on the Supertoinette Thermomix forum is this delicious walnut cake recipe. I really like the nutty flavour in this cake and the texture is soft and moist. The icing is nice and sweet, maybe too much so next time I will reduce the amount of sugar in the cake itself to balance the sweetness a bit better. The original recipe cooks the batter in one square cake tin and then the cake is cut in rectangles when cooled. However, I had financiers silicone mat so that’s what I used to cook the cake and it saved me a step.

Ingredients
For 16 financiers

150g walnuts
140g sugar (I will put 90g next time)
140g butter
70g plain flour
3 egg whites

Icing
140g icing sugar
3 egg yolks
1 tsp of vanilla extract or vanilla sugar

Method

  1. Toast the walnuts in a tray in the oven at 150C for 8 minutes to bring out the flavours. Leave to cool.
  2. Preheat the oven at 170C.
  3. Mix the cooled walnuts 5 sec/speed 7 until ground. Don’t overprocess or it will become oily.
  4. Add the flour and mix 2 sec/speed 3. Tip out and reserve in a bowl.
  5. Mix butter and sugar for the cake 3 min/speed 4 until pale and fluffy.
  6. Tip out into a big bowl and wash the TM bowl thoroughly with hot soapy water, then dry or use second bowl.
  7. Place the butterfly whisk and the egg whites in the bowl and whisk 4 min/37C/speed 3/Measuring cup OFF until firm.
  8. Take a quarter of the egg whites and fold it into the butter. Add a quarter of the flour/walnut mixture and fold it in the butter/egg whites. Continue folding the egg whites and flour/walnut, one quarter at a time.
  9. Place a bowl of water on the sole of the oven (this will stop the cake from drying too much while baking).
  10. Pour into a 20cm buttered square/rectangular dish (I used financiers silicone moulds) and bake at 170C (fan oven) for 35 minutes for the big cake or 18 minutes for the financiers. Take out and cool in the mould on a rack.
  11. While the cake cools down, make the icing: place egg yolks and icing sugar  and vanilla in the TM bowl with the butterfly whisk.
  12. Whisk for 5 min/speed 4/Measuring cup OFF.
  13. When the cake is luke warm, spread the icing over with a flat spatula. Wait until the icing starts to set and trace lines with a knife on the icing without cutting through the cake to mark where to cut later on.
  14. When the cake is completely cool and the icing is set, cut through following the lines and keep at room temperature in an airtight container.

    You mentioned the icing may be a bit sweet, can I suggest you mix it with lemon juice instead of water, it gives the icing a nice tang and counteracts the sweetness nicely.
    Love your blog ! It also gives me an opportunity to practice my. French : )

    • Hi Eve, thanks for your comment. Yes you could probably add lemon to the icing, it must be delicious although I would be careful not to put too much lemon so as not to overpower the walnut taste…
