These Guinness brownies are apt to become your new favorite cookie bar. Historically, the phrase "black and tan" referred to the much-reviled auxiliary force of English soldiers sent to Ireland to suppress the Irish rebels after the 1916 Easter Rising. Eventually, a much-loved drink made with half Guinness Stout and half Harp Lager assumed the name, and now this two-toned brownie (with the addition of Guinness) shares it.

How to Make It

Step 1

Place one rack in lower third of oven; place another rack in center of oven. Preheat oven to 350°.

Step 2

To prepare Tan Brownies, place 6 tablespoons butter and brown sugar in a medium bowl; beat with a mixer at medium speed until light and fluffy. Beat in 2 eggs and 1 teaspoon vanilla. Weigh or lightly spoon 5 ounces (about 1 cup) flour into a dry measuring cup; level with a knife. Combine 5 ounces flour, baking powder, and 1/4 teaspoon salt, stirring well. Add flour mixture and pecans to sugar mixture, beating just until combined. Spoon into a 13 x 9–inch baking pan coated with cooking spray, spreading evenly with a knife or rubber spatula. Bake at 350° in lower third of oven for 15 minutes.

Step 3

To prepare Black Brownies, melt chocolate and 4 tablespoons butter in a large microwave-safe bowl on HIGH for 1 minute or until melted, stirring after every 20 seconds until smooth. Add granulated sugar, stirring until well combined. Add 2 eggs, 1 teaspoon vanilla, and Guinness, stirring with a whisk until well combined. Weigh or lightly spoon 5 ounces (about 1 cup) flour into a dry measuring cup; level with a knife. Combine 5 ounces flour and 1/4 teaspoon salt, stirring well. Add flour mixture to chocolate mixture, stirring to combine. Pour mixture evenly over Tan Brownies.

Step 4

Bake on the center rack at 350° for 25 minutes or until a wooden pick inserted into center comes out almost clean. Cool in pan on a wire rack; cut into squares.

Very Tasty

Very good and easy to make.  They definitely have more the consistency of cake than a brownie, but the flavors are wonderful.  And being a chocolate lover I like the suggestion of adding chocolate chips, so I might add in some mini chocolate chips next time.

I consistently hear from people, "these are the best brownies I've ever had." I actually brought some to a friend who is from Ireland and he said, "Oh, I'm not much on sweets, but I'll try one." After he did, he was like, "I want the recipe. These are incredible!"

I am not sure mine turned out great! I too got the marbled look and in my oven the bottom third and middle rack are the same, so I didn't know what to do. I just baked both times in the middle rack. Overall, I don't think I would make this recipe again.

These brownies were soft, spongy and not overly sweet (in a good way). The Guinness adds a fun and interesting malty flavor. They definitely don't taste "light" - but I don't think they're chocolatey enough for a traditional brownie lover. Next time I am going to add some chocolate chips!

This recipe was awesome! Made it for a party and then took the leftovers to work the next day. So delicious and moist, I followed the recipe exactly and wouldn't change a thing!
