Mix the egg yolks together with the powdered sugar, until the texture is fluffy. Then mix in the ground walnuts.

In another bowl, mix together the flour with the baking powder. Then add it in little by little into the egg mixture.

Meanwhile, whip up the egg whites until they form stiff peaks. Fold it into the batter.

Pour the batter into a cake pan, which is 30 x 20 cm and has been lined with baking paper. Bake it for 15 minutes at 355°F.

For the cream, mix together the pudding powder, water and eggs, until they form a smooth texture. Place it aside.

In a pot, combine the orange juice, sugar and butter. Let them melt together and bring it to a boil.

Pour in the pudding and mix it in, while cooking it and allowing it to thicken.

Spoon out the orange-pudding mixture onto your sponge cake, which should have cooled down already. Then decorate the top of the cream with orange slices. Let the cream cool completely.

Create red jelly and pour it on the top. Place the cake in the fridge and let it set.

You will be able to cut it up and serve after it has set! The team of Recipe Videos wishes you luck in making your Orange Cake!
