Black & Tan Brownies


Black & Tan Brownies | From My Sweet Heart

Well, some GREAT Irish beer has certainly found it’s vocation in this pan of brownies!!! 

For me?  I’m more of a martini girl.  I find I usually only enjoy beer with certain kinds of food.  But much like adding coffee to chocolate, the Guinness beer in this recipe enhances the chocolate with rich, malt tones.  Many black & tan brownie recipes add another brownie layer as the “tan” component.  I decided to switch it up a bit by adding Harp Lager in a frosting!

Pale ale, peanut butter and butterscotch combine to make a luscious icing.

So this icing really lends a smoky, salty and sweet touch to this scrumptious malted chocolate!

These beer infused brownies are of course, perfect for a St. Patrick’s Day treat.  But they are also a perfect dessert for tailgating and barbeques.


Black & Tan Brownies | From My Sweet Heart


YIELDS:  10-12 brownies


For the Brownies:

  • 1 cup all purpose flour
  • 3/4 cup cocoa powder
  • 1/4 teaspoon salt
  • 1 stick unsalted butter, cubed
  • 8 oz semi sweet chocolate, chopped
  • 4 oz white chocolate, chopped
  • 4 eggs at room temperature
  • 1 cup granulated sugar
  • 1 1/4 cups Guinness stout

For the Frosting:

  • 1 1/4 cups of peanut butter chips
  • 1/4 cup of butterscotch chips
  • 1/4 cup Harp Lager or pale ale


  1. Preheat your oven to 375°F.  Spray a 9 x 13 inch pan with cooking spray, line with parchment paper and spray it again.
  2. Whisk together the flour, cocoa powder and salt and set aside. 
  3. In a glass or metal bowl set over a pan of simmering water, melt the butter, semi sweet and white chocolate, stirring constantly until smooth.  Remove the bowl from the heat. 
  4. In the bowl of your electric mixer, beat the sugar and eggs on high speed for about 3 minutes. 
  5. Slowly add the melted chocolate mix and continue to beat until combined. 
  6. Then, by hand, stir in the flour mixture until just combined.  Do not overmix. 
  7. Stir in the Guinness stout.  Your batter will be very runny.  Pour the batter into your prepared pan and bake for 20-25 minutes.  A toothpick inserted near the edge should come out clean.  Do not over bake.  The center will be soft.  Let the brownies cool completely before frosting.
  8. Place the peanut butter chips, butterscotch chips and ale in a glass bowl and set this over a pan of simmering water.  Stir until the chips are melted and the mixture is smooth.  Spoon the frosting onto the cooled brownies and using an offset spatula, spread evenly over the top of the brownies.  Work quickly before the frosting completely sets.  Cut the cooled brownies into desired squares and enjoy!

      Thanks! I guess it’s that time of year when everyone is pulling out their Irish recipes! But I have to tell you, these pale in comparison to your beautiful nutella peanut butter brownies! They look fabulous! : )

    Anne, you beat me to this! I was just talking with Paul last night about black and tan brownies. I love black and tans and thought that it would translate perfectly to a dessert. I love this, can’t wait to try it!

    • Anne says

      Cassie….I’ve seen black and tans done a couple of different ways and I would love to see what you do with it! : )

    I do love the malty flavor that beer imparts on baked goods, so these are definitely a winner in my book. Not only beer in the cake part but in the frosting as well. Delicious and irish-well done.

    My goodness Anne can it get any better than this! Are you sure that there is not a little bit of the Irish in you?

    • Anne says

      Thanks Dorothy! And people looking for a great St. Patty’s day recipe should head over to you for your Bailey’s pudding shots! Those look AWESOME! : )

    Delish! I love that you added white chocolate to the batter. I just bought a silicone brownie pan and can’t wait to try these. Super tasty!

    These sound killer! I don’t really care for brownies I make them for hubby as he likes them but I would eat this one. I love a good black and tan and in a brownie sounds even better. I have a special place for Guinness… I have always enjoyed it so much so that I even took the tour of the brewery in Ireland. LOL.

    • Anne says

      Thanks Susie! I love that you took a Guinness tour! How lucky! And I am glad you are back and really enjoying your pictures and postings of Spain! : )

    this is the second Guinness recipe I’ve seen this week. The first one was in a stew and now – in a brownie? Well, it’s not hard to imagine how well Guinness and chocolate would complement each other. Then you go and make it peanut butter and chocolate – the best of ALL combinations! Beautiful looking brownies with a very unique flavor profile. Great job Darlin!

    • Anne says

      Thanks MJ! I guess it’s that time of year for all of the stout recipes to come out! Your kabocha squash and fennel soup is just beautiful! : )
