This sweet potato granola cake is sweet and delicious with a Japanese twist. It's soft, fluffy, and sweet with a bit of crunch from the granola. This recipe has healthy sweet potatoes and granola for a nutrition boost without giving up on taste.
Preheat the oven to 356°F (180°C) and cover an 18cm square tin with baking paper. *3
Sift all dry ingredients (minus sugar) together in a bowl and put it aside.
Wash the sweet potato and chop it into 1cm cubes.
Soak the cubes in water in a bowl for about 10 minutes. Pat them dry with a paper towel and place them in a microwavable container.
Sprinkle 1 tbsp of sugar over the sweet potato and microwave for 2 minutes.
Add the butter into the sweet potato container to coat the sweet potato with butter, then set aside.
Put the egg and 4 tbsp(or 60g) sugar in a large bowl and whisk them together with a handheld mixer. *4
Add the oil and beat all together.
Add half of the milk to mix and fold the half of the sifted dry ingredients.
Add rest of the milk and then add all the sifted dry ingredients. *5
Add 2/3 of the sweet potato and 2/3 of the granola and fold them into the wet mixture but do not mix too much.
Pour the mixture into the prepared square tin and top with the remaining sweetpotato and granola and sprinkle the black sesame seeds on top.
Bake for about 20 minutes, depending on your oven.
Serve fresh from the oven or allow to cool.
Notes
*1 I used olive oil for the updated photos, but you can use sesame seeds oil or other oil.*2 I used homemade granola but you can use store bought granola. *3 For the update, I did not use a square tin but used "Italian muffin cups" bought from a local Daiso shop. *4 If you don't have a handheld mixer, you can just use a whisk. *5 try not to overmix the batter. *baking time is indication only. Insert a skewer and if it comes back clean, cake is baked.
