Guinness Brownies


St. Patrick’s Day is next week!  As a kid it a was holiday for wearing green and pinching kids that forgot the dress code memo.  After 21, St. Patty’s Day becomes a giant, enormous all-day drinking fest.  

Restaurants, bars, and pubs all over the country will be serving all sorts of Irish-inspired fare, as well as interesting green hued concoctions.  Think green velvet cake (instead of red velvet cake), green chocolate, and even green beer!  A couple of years ago when I lived in Chicago, I watched the Chicago River turn green for the holiday. 

TheChic_guinness-brownies-3I’m not much of a beer drinker, but I’m still celebrating St. Patty’s Day with a bottle of Guinness!  Oh no, I’m not drinking a pint.  I’m making delicious, decadent, fudge brownies with that stout beer.

With these caramel fudge topped Guinness brownies, I assure you no hangovers the following morning.  However, if you don’t share these brownies… there may be a lot of regret and exercising in your future. TheChic_guinness-brownies-instructions

Guinness Brownies
  1. Preheat oven to 350 degrees F. Line a 9''X13''inch baking pan with foil, allowing the edges to hang over. Set aside.
  2. Set up a double boiler by placing a bowl on top of a pan of simmering water. The bowl should not touch the water. Place butter and chocolate chips in bowl. Melt butter and chocolate. Stir as needed to ensure even melting.
  3. Once melted, remove from heat and add sugar and brown sugar. Stir to combine.
  4. Add eggs on at a time, making sure each egg is fully incorporated before adding the next. Mix together using a hand mixer, or simply using a sturdy spatula.
  5. In another bowl, whisk together flour, cocoa powder, and salt. Alternate adding dry mixture and Guinness to the batter. Start and end with the dry mixture. Fold in chocolate chips.
  6. Pour batter into prepared pan. Bake for 25-30 minutes until toothpick inserted in center of brownie comes out clean. Let brownie cool in pan while you prepare fudge.
Caramel Fudge
  1. In a medium sauce pan, melt butter. Add brown sugar and corn syrup and stir to combine. Add sweetened condensed milk and heat oven medium-low heat. Do not boil mixture. You just want it to be hot enough for the white chocolate chips to melt.
  2. Add white chocolate chips and pinch of salt. Remove from heat and stir until chips have melted and mixture is smooth. Pour mixture over slightly cooled brownies. Spread into an even layer. Let harden at room temperature or store in the fridge uncovered.
  3. Let fudge set for at least 1 hour (best if let set overnight) before slicing and serving.
  4. If desired, drizzled melted semi-sweet chocolate over set fudge for decor and added garnish.
  1. *For drizzling chocolate, melt 1/4 cup chocolate chips in the microwave at half power for 45-60 seconds. Stir until smooth. Transfer to small piping bag, or drizzle with spoon over set fudge.
The Chic Site
Maryanne’s Chic Tip: Let the brownies chill in the fridge for at least 2 hours to ensure brownies are sturdy enough for slicing.  When slicing out portions, wipe your knife clean after every cut so brownies stay nice and clean.

    In the ingredients you did not mention how many eggs, but in the directions for step 4 (which overall seems incomplete) you did. Please clarify. Thank you 🙂

    The recipe instruction 4 for the brownies says to add eggs one at a time however the ingredient list doesn’t list eggs. How many eggs are required for this recipe? Many brownie recipes call for 3-4 eggs.

  3. Lauren @ A Nerd Cooks

    I just made these for some friends at work. The fudge is currently cooling and hardening. Can’t wait to dig in!!

    Love the recipe and plan on trying it out soon! One gripe, however. PaTTy is a girl’s name. The proper shortened form of Patrick is PaDDy.

      That’s a good point Tim… I guess I’ve always just written it as Patty’s (don’t think I’m alone in that) but you’re absolutely right, it should be Paddy. My Irish ancestors would be so ashamed of me. =) ~Rachel

    Why does the recipe list semi sweet chocolate chips twixe? 1 1/2 cup and then 1 cup? What’s the correct amount?

    • jonathanmelendez

      Hello Lynnette, you actually need both (so 2 1/2 cups) chocolate chips. The first 1 1/2 cups goes into the double boiler to be melted at the beginning, and then the second 1 cup of chocolate chips goes folded into the batter that the end! Hope this helps! ~Jonathan

    Do you have to leave the beer to sit for a while? Am wondering if the bubbles (or lack of) will affect the batter.

    • jonathanmelendez

      Hello Skye, Thanks for your question! You actually don’t have to let the beer sit. The foamy bubbles wont affect the batter or the taste of the brownies at all! Hope you give these a try really soon! ~Jonathan

    These look beautiful! Can you tell me how much sweetened condensed milk to use? I’ve seen different size containers.

    • jonathanmelendez

      Hello Valerie! It’s a 14oz can of condensed milk! Let us know what you think of these brownies once you make them! ~Jonathan
