I fancied a spot of baking this week especially as it seemed to be a while since I baked a cake for my blog. This recipe is extremely easy to make, even if you’re an inexperienced baker, there is little to go wrong here. The cake is naturally dense in texture so you haven’t got to worry about whisking for a specific length of time or getting a good rise. The decoration is optional, the cake tastes just as good with or without icing. The mixture is not particularly sweet and makes a good alternative dessert topped with fruit, accompanied with free-from cream or ice-cream.

The cake gets its rich yellow colour from polenta and cold pressed rapeseed oil. I’m very fortunate to have an excellent local supply of this amber coloured oil called Summer Harvest. The rapeseed is harvested just down the road from my house. The oil has an earthy, nutty flavour and makes an excellent addition to any recipe with nuts and seeds added to it. If you prefer to use an alternative oil, us sunflower oil which adds little extra flavour but the cake will also be paler in colour.

I usually use just ground almonds and polenta in this recipe, but for a change,  I ground up flax seed with whole almonds to make a fine meal. As long as you grind the seeds or nuts finely, you should be able to use any combination with polenta in this recipe. I use an electric coffee grinder to make my own seed and nut flours, I find the sturdier blade is able to blitz more finely than the food processor or blender.

Serves: 8

Ingredients

  • 150ml cold pressed rapeseed oil
  • 1 tsp good quality natural vanilla extract
  • 150g unbleached caster sugar
  • 100g silken tofu
  • 50g each flax seeds and whole almonds, finely ground
  • 125g polenta
  • 5g gluten-free baking powder (such as Dr Oetker)
  • 10g arrowroot

To decorate:

  • 100g ready to roll white icing
  • ½ tsp good quality natural vanilla extract
  • A handful of fresh berries
  1. Preheat the oven to 180°C (160°C fan oven, gas 4). Grease and line an 18cm a round cake tin. Pour the oil into a bowl. Add the vanilla and sugar and whisk together until creamy and well blended. Add the tofu and whisk again until smooth.
  2. Add the seed mix, polenta, baking powder and arrowroot, and gently mix all the ingredients together until well blended. Scrape into the tin. Stand the tin on a baking tray and bake for an hour – test the centre of the cake with a wooden skewer, it should come out clean when the cake is properly cooked through. Leave to cool completely in the tin.

  3. To decorate the cake, remove the cake from the tin and place on a wire rack. Cut up the white icing into pieces and put in a small saucepan. Add 1 tsp water and heat the mixture very gently, stirring, until it begins to melt and form a paste. Stir in the vanilla, then drizzle the icing all over the top of the cake using a dessert spoon, letting it drip down the sides. As the icing cools, it will set firm again.

  4. Leave the icing to cool and scatter, then scatter the top with berries before serving. I used my latest precious harvest of blueberries. Not a very good year for them in my garden, but the berries do have a good flavour none the less. Have a good week 🙂
