St. Patrick’s Day always makes me think of my beer of choice: Guinness. Love it or hate it, it’s nearly a tradition come March 17th, and I am all for love. Love it shall be, and brownies there shall be.

I may sound like a lush in the above paragraph. Forgive me. In reality, I don’t drink much. I’m not particularly large, so I tend to sip one drink and never finish it. This makes my husband a great person to share dinner drinks with. He’s also a great person to share brownies with. He likes the outer edge of the pan, and I prefer the gooey inside ones. Yes, our marriage is based on how we eat together.

I’ve made Guinness brownies before, but unfortunately, I never really enjoyed them all that much. It has a lot to do with the fact that they end up rather fudgy instead of having that brownie crumble that I know and love.

To eliminate this problem, I opted to use Guinness as a flavor enhancer to simply bring out the dark chocolate. You don’t get overwhelmed by the Guinness flavor, but you get a dark, rich chocolate brownie that’s worth every bit of effort it takes to make it.

Do you celebrate St. Patrick’s Day? We usually end up at our friend’s house for an Irish breakfast, but we don’t tend to do much else on the day itself. I suppose this shows my age and unwillingness to brave the crowds.
