In a bowl, put an egg, melted butter and whisk little with a whipper.
Put okara powder, sugar substitute, soy milk and vanilla extract in the egg and mix well.
<If you use a microwave>
Spread plastic food wrap on a middle size flat plate pulling every corner of the wrap so that the surface is completely horizontal.
Place 1/4 of the crêpe mix on the food wrap and spread evenly.
Set the microwave to 600W and microwave for a min.
Check the crape and if needed, add 15 sec more.
<If you use a pan>
Heat a pan for a while before putting crêpe mix. When it is heated, put the pan on a wet cloth. After hearing sizzling sound, put the pan back to the stove.
Turn on the heat little weaker than middle. Spread the 5 ml of some oil on the pan and put 1/4 of crêpe mix on the pan.
When you start seeing the crêpe skin edge getting dried, turn the heat low.
When all the skin is seemingly done, peel off the crape from the pan by spatula. flip carefully.
Heat another side for 1-2 min by low heat.
When the other side turns its color brown, it is done.
