This is a variation on a recipe my friend taught me. If you want to make it richer, use 2 egg yolks, butter, and vanilla essence, and add some rum once it has cooled. This is a variation I made when I was a newly-wed. You can freeze leftover egg whites.

When adding the milk to the dry ingredients, add it in multiple batches so that lumps do not form. The cream will seem a bit thin once finished, but it will thicken as it cools. If you add an egg yolk, it will become rich and more like regular custard cream. Recipe by Yuuyuu0221
