Place the Dr. Oetker Nona Cupcakes Vanilla mix, water and egg in a mixing bowl. Mix at high speed for 1 minute.
Bring water to boil in a steamer.
Add in vegetable oil and mix until batter is light and fluffy.
Prepare 12 egg shells.
Use aluminium foil to create nests inside the muffin tin. Place the egg shells upright in the muffin tin and make sure they are secure.
Pipe the batter inside the egg shells (each about 2/3 full).
Steam for 15 to 20 minutes, then set aside to cool.
Peel the egg shell, decorate with chocolate sprinkles and chocolate chips.
Tip: To prepare 12 egg shells, crack a small hole on the egg gently and pour out the contents. Rinse the egg shells and set aside.
