Happy Birthday Daddy & Healthy Sweet Potato Chocolate Cake Recipe! #shop #cbias

Disclosure - Collective Bias Blog Post This weekend, it was a very special weekend in our household as we celebrated daddy’s birthday. We wanted to make him feel special and loved by making him a birthday cake.

While daddy was out, we went Shopping at Asda for Cadbury Chocolate and, after checking nearly every single chocolate bar in the store, we picked up a couple of Cadbury Dairy Milk Whole Nut for our cake.

Little man loves baking and helping out in the kitchen, so he was ready with his chef’s hat to make daddy’ surprise birthday cake.

Daddy loves chocolate, but he is on a diet, so we couldn’t just make him any chocolate cake. After searching online for a suitable low-calorie recipe, I found a few sweet potato chocolate cake recipes and decided to make my own version of it.

Healthy Sweet Potato Chocolate Cake Recipe


  • 1 bar of Cadbury Dairy Milk Whole Nut
  • 3 medium eggs
  • 1 cup brown sugar
  • 3 tbsp olive oil
  • 1 large cooked sweet potato
  • 1 tsp vanilla extract (or 1tbsp vanilla essence)
  • 2 tbsp cocoa powder
  • 1 cup flour

Pre heat oven to 180C.

To cook the sweet potato, wash thoroughly, peel, chop into small pieces and boil in a saucepan until soft when poked with a knife.

When cooked, let cool. Blend or mash the potatoes until slightly smooth but still some chunks remaining.

Place the chopped chocolate in a bowl and microwave on low for approximately 1 minute until chocolate has just melted. When you remove from the microwave, stir quickly to melt any pieces that are still solid. (Before melting the chocolate, you should try to make sure it tastes ok).

In a separate bowl, whisk together the eggs, sugar and oil. Slowly add the cooked potato, the melted chocolate and vanilla into the egg mixture. Beat until just combined. Don’t over work it.

Sift the cocoa. Add this and the flour, baking soda and salt to the wet ingredients. Fold the ingredients until everything is just combined. Don’t over mix the batter.

Spread a teaspoon of butter or oil over the surface of two cake pans. Sprinkle some flour all over, and tap out the excess. Separate the mixture in half and pour the cake batter into the prepared cake tins. (Don’t forget to lick the spoon to try the cake mixture).

Bake for approximately 20 minutes. Cake is ready when a tooth pick or skewer inserted in the middle of the cake comes out clean. Baking time may vary depending on the pan and oven you are using. Remove from oven and leave to cool in the pan.

Chocolate Sauce

  • 1 cup cocoa powder
  • 1 cup water
  • 4 tablespoons honey
  • 4 tablespoons olive oil.


Place all ingredients except the olive oil in a small saucepan on high heat, stirring to combine. Let mixture bubble for 5 minutes, stirring to keep it from sticking to the bottom of the pan. Mixture will start to thicken.

Add olive oil and stir vigorously to incorporate oil into the chocolate mixture. Remove from the heat and allow to cool before using it to top the cake and same in between the layers.

Once the chocolate cake was ready, we decorated with candles and wrote Daddy 31 – sorry daddy, we are giving away your age, hope you don’t mind. You still look 21!

Little man had fun decorating the table with daddy’s birthday cake and blue balloons. While the cake was in the oven, we made a special present for daddy, a painting which says “Love You Dad xx” with handprints.

Once daddy came home, he was very happy with his surprise birthday cake, balloons, cards and painting. He also said the Healthy Sweet Potato Chocolate Cake was one of my best chocolate cakes to date and he couldn’t even tell there was sweet potato in it.
