  • 90 grams unsalted butter cubed
  • 90 grams milk chocolate
  • 300 grams sweet potatoes
  • 90 grams granulated sugar
  • 2 eggs
  • 1 tsp vanilla extract
  • 90 grams all purpose flour
  • 1 tsp baking powder
  • 1 tbsp cacao powder
  • 100 grams white chocolate
  • 18 edible eyes


  • Preheat oven to 180c, and grease a 20cm square brownie pan.
  • Boil sweet potato chunks in water, until they're cooked and soft. And then mash them using a potato masher.
  • In the microwave, melt the butter with the chocolate.
  • In a bowl, add sweet potato mash, eggs, vanilla extract with sugar and butter chocolate mixture. Beat until smooth.
  • Sift in flour, baking powder and cacao powder. Mix well.
  • Pour mixture into brownie pan, and smooth out the top. 
  • Bake for 20-25 minutes. Make sure not to over bake the brownies, remove from oven when mixture is still soft in the middle.
  • When brownies cool down, remove from pan and cut into 9 squares.
  • To decorate for Halloween, melt the white chocolate in the microwave and place in a ziplock bag. Cut the corner of the bag, and pipe out back and forth in a zig zag motion to create Mummies.
  • Decorate with edible eyes, and place in the fridge for the chocolate to set.
