Buttermilk Biscuits

Bought these for the first time today. The ingredients are pretty much what you would use in a homemade biscuit: wheat flour, buttermilk, butter, sugar, baking powder, salt and baking soda. The frozen biscuits are square, so the shape after baking is not exactly round, but they are tender and buttery. The package states to bake them at 400 degrees for 8-10 minutes, but I ended up baking them for a total of 15 minutes to get them nicely browned
