Sweet Potato Cake Bars

Sweet Potato Cake Bars

These are bite-sized sweet potato cakes with a crispy cookie base.

Ingredients: 18 cm square tray

Sweet potato
420 g
60 g
30 g
Heavy cream
50 g
Egg yolk
1/2 teaspoon
Biscuts or cookies
100 g
50 g
Egg yolks for glazing


1. Finely crumble the biscuits. Place in a bowl and add melted butter. Mix well.
2. Line the tray with baking paper and fill with the biscuit mix, pressing it firmly into the bottom of the tray. Chill in the fridge.
3. Meanwhile, cut the sweet potato into 2 cm thick slices and cook until softened.
4. Once cooked, peel the skin and mash in the saucepan.
5. Add the rest of the ingredients into the mashed sweet potato and mix.
6. Stir over a low heat for about 2-3 minutes to achieve a smooth consistency. Remove from heat.
7. Pass through a strainer. If you want lumps of potato in the bars, you can skip this step. Now you have sweet potato cake puree!
8. Put the puree into the tray from Step 2. Cover with plastic wrap and smooth out the surface with your palms.
9. Try to get the surface smooth as show in the picture.
10. Mix the egg yolk for glazing with 1 teaspoon of water. Brush onto the surface evenly.
11. Bake in a preheated oven at 200℃ for about 20 minutes until surface turns golden brown. Chill in the fridge first and then remove from the tray.
12. I sliced the cake into 9 bars and then cut in half. They're best served at room temperature.
13. Wrap in parchment paper and give away as gifts.

Story Behind this Recipe

I saw sweet potato cake bars advertised on a home-delivery site. I figured I could make them myself, so gave it a go.
