Make the frosting first as it needs time in the fridge to firm up. To make the frosting, combine all the ingredients except the coconut oil in a blender, finishing by blending in the oil. Blend until totally smooth, cover the surface completely with cling film (plastic wrap) and refrigerate for about 8 hours or ideally overnight to thicken.

Preheat the oven to 170°C/325°F/Gas Mark 3. On a baking tray, lightly toast the walnuts for 5–8 minutes, until just beginning to colour, leave to cool then chop into small pea-sized pieces. Grease an 18–20 cm (7–8 inch) loose-bottomed cake tin with rapeseed oil and line the base with baking parchment.

In a large bowl, mix together the walnuts with all the dry ingredients from the teff flour to the sultanas (seedless golden raisins). In another bowl, mix together the oil, pumpkin purée, grated carrot, orange zest and eggs. Make a well in the centre of the dry ingredients and pour in the wet ingredients, folding them in until combined.

Pour the mix into the prepared tin and bake for 30–35 minutes, rotating halfway through baking, or until a skewer inserted in the centre comes out clean. Leave to cool in the tin and then demould. When cool, cut in half and fill with half the cashew orange ‘frosting’, spreading the remainder on top. If your frosting is a little too runny and needs to be firmer, give it a blast in the freezer for about 10 minutes. Decorate with fresh flowers, if you wish.

This keeps well for up to five days in the fridge. It freezes well too, without the frosting.

NOTES

You can also make muffins with the cake mix. Just divide the mix between eight muffin cases and bake at 170°C/325°F/Gas Mark 3 for 15–20 minutes, turning halfway, until a skewer inserted into the centre of a muffin comes out clean. Top with the frosting, or they’re delicious without.

Pecans work well instead of walnuts in this cake.

When you start to make these delicious dairy-free nut creams you will realize how amazingly versatile and useful they are to go with your Clean Cakes, or in your day-to-day cooking.

Cashew nuts are a really useful ingredient, especially for those who do not eat dairy, as they can be whizzed up to make silky milks and creams. This unctuous cashew cream is perfect served with any of my Clean Cakes, plus it is the base of some icings (frostings), ‘yogurts’ and raw cakes. It is delicious as it is, or you can adapt it by adding your preferred natural sweetener or other flavourings such as vanilla. I also love to add it to smoothies and stir it into granola, fresh fruit or porridge.

For a savoury twist, make a non-dairy soured cream by adding nutritional yeast flakes or powder, lemon juice and salt to taste to the cream. Then stir into soups or enjoy with tacos and chilli.

Makes about 380g (13 1/2 oz/ 1 3/4 cups

Soak the cashew nuts in 500 ml (17 fl oz/21⁄8 cup) of filtered water and 1 tsp of Himalayan pink salt for 3–4 hours. Drain and rinse thoroughly.

Blend the nuts with the almond milk until completely smooth, stopping the blender and scraping down the mix when necessary. The end result must be totally smooth for use in all recipes.

The cream will keep in the fridge for at least four days in a sealed glass jar.”
