Guinness brownies with mint whipped cream

What makes a brownie better? Booze!

The only time in my life I’ve enjoyed Guinness was in Ireland on the Guinness factory tour when I was handed a free pint in the tasting room high above the streets of Dublin. I’m thinking the fact that I was severely jet-lagged, working on about one hour of sleep after our trans-Atlantic flight and the fact that it was free were the only two reasons the beer actually tasted good to me that day. Every time prior and every time since, I take one sip fully expecting a chocolate-like taste and get utterly disappointed when it, of course, tastes nothing like chocolate.

The solution to that is, of course, to put it in chocolate. While I’m not much of a fan for drinking it straight up, Guinness is delicious in long-simmered stews and chocolate baked goods, brownies being one of them. These boozy bites are perfect and festive for any St. Patrick’s Day celebration.
