Quaker Oat Pancake Mix as substitute for Bisquick

[CathMac]

I substituted the Quaker Oat Pancake Mix for Bisquick in their Praline Meltaway Biscuits. I've never made these before so I don't know what the texture should be like but they seemed a little heavy.

Does anyone have any educated guesses on whether I should add some baking powder to leaven the mix a little more?

Thanks,
