Mixed Berry Brioche

Mixed berry brioche pastry. Variation of a recipe from Artisan Bread in Five.  This came out huge!  Also I was a little sloppy in making it and made a lot of changes to the original recipe.  There's a layer of custard underneath the berries but when it came out of the oven it was gone.  There are a few factors in which I made a few shortcuts that probably resulted in the disappearance.  Lesson learned.
