I tried the Bakerella Butterscotch ganache brownies(which tasted more like a cookie). It was good but I overcooked the brownies which made it a little crunchy. It tasted better the next day. Anyway here is her recipe that I used from Nestle's website
BAKE for 30 to 40 minutes or until wooden pick inserted in center comes out clean. Cool in pan on wire rack.
I cooked these in 2 9" round pans for 24 minutes and that was too long. So just watch your time if using something other than a 9x13 pan.
After they were cooled I poured Butterscotch ganache (6 oz. butterscotch morsels, 6 Tbsp heavy whipping cream, 3 Tbsp unsalted butter, In a small saucepan, heat cream and butter until just before the boiling stage. Pour over the butterscotch morsels. Let stand about 20 seconds and stir until smooth) over the brownies. I then stacked them and poured chocolate ganach (substitute half semi-sweet and half milk chocolate chips for butterscotch) on top and layered with butterscotch chips.
