Any type of berry will work in this recipe, I just happen to be fond of blackberries. As berries go, blackberries are my favorite, followed closely by blueberries. These bars are moist and delicious and hard to resist.
They were absolutely delicious, but I would change one thing next time. The mozzarella is mixed in with the streusel topping, which is rather good, but the pieces on top became quite brown and too chewy. This took away from the bar. So next time, and I’ve adjusted this in the recipe below so it doesn’t happen to you, I would separate the streusel topping, add cheese to just the half for the crust, and leave it out of the top layer. Another option is to sprinkle the cheese on top of the berry layer and then add the topping.
Don’t try to cut or move these until they are completely cooled, otherwise they’ll fall apart. They need to be cooled off in order to bind together. Definitely delicious!
Sargento did compensate me for the time I dedicated to making this recipe and putting this post together for you, however my opinions on flavor and preparation are 100% mine. :)
