Guinness Brownies with Bailey’s Buttercream Frosting

by megan on March 16, 2012

I am ready for tomorrow’s St. Patrick’s Day party! I have seen many versions of Guinness Brownies the past couple of days, and decided to come up with my own version. I whipped up 36 of these delicious brownies and 35 of them are ready to go. I couldn’t resist taste testing! I just might have taken a spoon to the bottom of frosting bowl after all the brownies were topped!! I am definitely making these little gems again!!! The recipe below makes 12 brownies. Enjoy!
