Unlike the eclair desserts made with graham crackers, this one has a baked crust that has a texture and taste like the real thing. It puffs up and gets all bubbly! The filling is custard-y, and the chocolate icing is sweet. In short - it really is like an eclair, only much easier to make. Even though the recipe has three parts, it really doesn't take too terribly long to make. This recipe has circulated within my family for at least 20 years, and it's still a big favorite. Reduced fat and sugar-free products can be used and it will still turn out great. In place of the unsweetened chocolate squares, you can use 6 tablespoons of unsweetened baking cocoa + 2 tablespoons of butter. Cook time does not include refrigeration time, so please allow for that.
