Chop apples into bite size pieces and place in a saucepan with water and vanilla essence on a medium/low heat.
Allow apples to cook for approximately 10 minutes to soften.
Once cooked remove from heat, drain liquid and stir through all spice.
Preheat oven to 160 degrees fan forced and grease 4 small ramekins.
Separate stewed apple evenly between the 4 ramekins.
To make sponge, beat egg, sugar and vanilla essence in a bowl using a hand held electric mixer until mixture is thick and creamy, almost doubled in size.
Using a metal spoon, fold through amaranth flour and baking powder without over mixing. Mixture will be light and fluffy.
Pour sponge mixture evenly over stewed apple.
Bake in oven for approximately 20-25 minutes until golden brown and sponge is cooked.
