In a mixing bowl, add-in the grated cassava, sugar, and pour-in the egg and melted butter. Mix the ingredients until well-incorporated.

In a flat workspace lined with wax paper (to avoid sticking), place the cassava mixture and then flatten it using a rolling pin.

Transfer the flattened mixture into a steamer. Steam for 15 minutes. Wrap the cover of the steamer with a towel to avoid water from dripping.

Place the mixture back on the flat workspace. Generously scoop peanut butter and spread at the bottom center of the mixture and then scoop crushed peanuts and spread it within the area of the peanut butter. Wrap the fillings by rolling the mixture upwards.

Cut the rolled cassava mixture about 2-inch intervals and completely coat each one with more crushed peanuts.

Transfer to a serving plate or serving tray. Serve and enjoy!
