Whole Egg Custard (Easy and Quick Recipe)

The whole egg custard is a simple and clever variation of the classic recipe, perfect for those who want to avoid waste in the kitchen. Usually, I make the custard using only egg yolks, as tradition dictates, but many people in the comments have asked me: “Can I use the whole egg?”
The answer is yes, and the result is truly excellent!
The texture remains soft, velvety, and stable, ideal for filling cakes, pies, cream puffs, sweet rolls, or enjoying by the spoonful. The only difference is the color, which is slightly lighter than custard made with just yolks, but the flavor remains full and delicate.
This version is perfect when you have little time, want to use simple ingredients, or need a light yet delicious custard. With few steps and one egg, you prepare a smooth, vanilla-scented custard ready for a thousand sweet recipes.
