Sweet Potato Cake with Cream Cheese Icing

Sweet potato cake - the finished product

Ahh, sweet potato cake, what’s not to love. I love the humble sweet potato as you can see by the related recipes. But rarely is it used in sweet treats or desserts and this seems a real shame.

Sweet potatoes are a great source of fibre as fully of vitamins and minerals including iron, calcium, selenium, most of the B vitamins and vitamin C. And they’re packed full of beta-carotene.

And this cake is delicious. It’s rich and moist with the spices giving it a depth of flavour.

Give it a try and let me know how you get on.


Sweet Potato Cake

Sweet potato cake - ingredients2 large or 3 medium sweet potatoes (one of these would count as one of your 5 a day!)
2 cups plain flour
1 ¾ tsps baking powder
½ tsp bicarb of soda
½ tsp table salt
1 tsp ground cinnamon
¼ tsp ground ginger
Two pinches ground cloves
½ cup or 115 g unsalted butter, at room temperature

  • Spread the batter in the pan and then bake for 40 minutes or so. You can test with a knife inserted into the centre until it comes out clean.
