Health benefits of purple sweet potatoes
Purple sweet potatoes are not only delicious but also packed with health benefits. They were recently featured in the Netflix documentary, Live to 100, and this is exatly where I got the idea to start creating recipes with this wonderful vegetable! I have always thought that the purple sweet potatoes are way too sweet to eat as a savoury food and therefore choosing to make a chocolate cake with these delicious potatoes just made sense!
They are rich in antioxidants, which help protect your body against free radicals and reduce inflammation. These antioxidants can also promote heart health and improve blood flow. Purple sweet potatoes are also a great source of fiber, vitamins, and minerals. They contain high levels of vitamin C, which can boost your immune system and support collagen production. Incorporating purple sweet potatoes into your diet can provide a wide range of health benefits.
Ingredients for this 3 ingredient chocolate cake purple sweet potato recipe
To make this 3 ingredient chocolate fudge cake recipe you will need:
For the cake:
- 1 cup dark chocolate chips (180grams)
- 2-3 Japanese medium sized purple sweet potatoes
- ½ cup plant milk of choice
For the icing:
- ⅓ cup dark chocolate chips (60 grams)
- 3 tablespoon plant milk of choice
Step By Step Instructions For Making This Chocolate Fudge Cake Recipe
To make this purple sweet potato recipe follow these steps:
- Wash and peel the purple sweet potatoes.
- Chop into smaller cubes sized pieces and boil for 15 minutes.
- The potatoes need to be extremely soft, almost falling apart when picked up. Drain the potatoes and add to a large blender or food processor.
- Melt 1 cup of dark chocolate chips slowly in the microwave.
- Add melted dark chocolate and 1 cup of almond milk to the blender / food processor. Blend smooth. It is important to ensure the mixture is well blended to avoid stringy pieces of potato in the cake.
- Pour the mixture into a baking paper lined cake tray or a spring cake pan. The cake is a fudge like texture. If you want to take the whole cake out of the pan keep in mind that you will need to use baking paper. I have used a spring cake pan and can easily take 1 piece at a time, leaving the cake on the base of the pan.
- For the icing, melt dark chocolate and mix in the almond milk. Pour on top of the cake. Refrigerate the cake overnight or until cold / firm.

- Blend the sweet potato mixture thoroughly to avoid any lumps or stringy pieces of potato in the cake.
- Line the cake pan with baking paper to easily remove the cake, or use a spring cake pan if you prefer to serve the cake directly from the pan.
Variations and additions to the chocolate cake recipe

- Add nuts: Fold in chopped walnuts, pecans, or almonds into the batter for an added crunch and nutty flavor.
- Cherry flavour: Make this a cherry chocolate cake by subtituted the almond milk for cherry juice. You can then top the cake with fresh cherries! This is a variation that I am definitely going to try!
- Mint chocolate: Add a few drops of peppermint extract to the batter for a refreshing mint chocolate flavor (another one I'm 100% going to try!)

Expert advice about purple sweet potatoes and the chocolate cake recipe
Can I use regular sweet potatoes instead of purple sweet potatoes?
While regular sweet potatoes can be used as a substitute, the flavor and color of the cake may differ. Purple sweet potatoes have a unique sweetness and vibrant purple color that contribute to the overall taste and appearance of the cake. Therefore, you can substitute for regular sweet potatoes but it won't be as sweet as the purple sweet potatoes and I therefore recommend that you do your best to get your hands on some purple sweet potatoes!
Can I use a different type of chocolate?
Yes, you can use different types of chocolate depending on your preference. Dark chocolate with a high percentage of cocoa content is recommended for a rich and intense flavor but you can use a sweeter milk chocolate if that is your preference.
How should I store the leftover cake?
Store the leftover cake in an airtight container in the refrigerator for up to 3-4 days. This cake is best served cold, straight from the fridge.
Can I freeze the cake?
I haven't tried it! I'm currently freezing a piece now. I will report back soon on the results.
