"This is basically an open faced eclair with a slight twist. A fairly light dessert that's pretty easy to make. It's called MOON pie because when the pate a choux is baked, in a sheet form for this, it has bumps & dips like the surface of the moon. Although I like making homemade pastry cream & cocoa fudge icing when I make eclairs & cream puffs; with this dessert I find it's best to use cook & serve vanilla pudding (or homemade pudding) because it sets better (so that when you start spreading on the top layer it doesn't mix in with it). I also use hot fudge ice cream topping instead because it's thicker and holds up better...."
