Guinness Brownies

These Guinness Brownies are a fun treat that any beer lover will enjoy! They are fudgy, rich, and extra chocolatey, deep dark and filled with amazing stout beer flavor. + They’re easy to make with pantry ingredients and completely guilt-free – made with wholesome ingredients without refined sugars. Make these for St Patrick’s Day or any day.

Last week was awful. I couldn’t focus on anything but that unfortunate Coronavirus. We were following the news about the outbreak, trying not to worry too much. But no matter how hard we tried to stay calm, we still got affected by the news. And then we struggled not to get sucked into the overall mass panic.

So my brain was in complete lockdown for a few days. I almost canceled everything cheerful I had planned for my family. Even our St Paddy Day festivities were in question!!! But then I just stopped and said NO. No one and NOTHING will disrupt me from having fun times with my family. Every year we celebrate St Patrick’s Day, and we’re not canceling ANYTHING due to Coronavirus this year. 

Baking always sets my mind to a happy place, so to fight all the bad news, I just grabbed the bowls, whisk, and ingredients and decided to make this chocolate beauty. Honestly, these Guinness Brownies saved me from getting completely mad.

Last year I made Guinness Chocolate Cake for my boys, and Irish Soda Bread Muffins are regularly on the menu every year. This year I decided to make something super simple, from pantry ingredients. With the addition of Guinness beer, of course.  These Guinness Brownies turned out fabulous. Deep dark, luxurious. Fudgy and chocolaty. Loaded with incredible bittersweet flavor. So irresistible. So addictive. Just what we need to boost our mood. 

Guinness Brownies ingredients

These Guinness Brownies look luscious. But if you think this dark beauty will ruin your waistline, this is where you’re wrong. These chocolate brownies are completely guilt-free, made with wholesome ingredients, and without refined sugars. To make these delicious brownies you’ll need:

• DARK CHOCOLATE: I used 100% dark chocolate that is simply processed cocoa beans, without any added fat or sugar. What makes dark chocolate so healthy is the antioxidants called flavonoids. They are found in the largest concentration in chocolate with the highest amounts of cacao — the solid part of the cocoa bean that gives chocolate its characteristic color and flavor. If you can’t find 100% dark chocolate, then look for a minimal 75% dark chocolate. The darker, the better
• OAT FLOUR: I used whole grain oat flour here. It is one of the staples in my pantry. If you don’t have oat flour, you can simply make one. Just take simple OATS and grind them in flour. Oats are an excellent source of fiber, especially beta-glucan that is known for its power to lower cholesterol and keep your heart healthy (1). Also, oats are high in vitamins, minerals, proteins, and some powerful antioxidants. I use oatmeal flour often in my baking as a substitute for all-purpose wheat flour. 
•  
• CACAO POWDER: In this recipe I used raw cacao powder that is unprocessed, bitter, deep-flavored and incredibly healthy. Cacao is one of the richest sources of polyphenols – an antioxidant that has been linked to many health benefits, including reduced inflammation, better blood flow, lower blood pressure, and improved cholesterol and blood sugar levels. (2) If you haven’t yet, seriously, invest in a good quality cacao powder. Cacao powder health benefits are numerous and you won’t feel guilty indulging in chocolate treats that calls for this incredible ingredient anymore. This SUPERFOOD is filled with only good healthy calories.
• BUTTER / COCONUT OIL: I usually use coconut oil when baking BUT to add up to St Patrick’s celebration mood, this time I used organic unsalted grass-fed butter. 
• COCONUT SUGAR: To sweeten these Guinness Brownies, I used coconut sugar. Coconut sugar is a natural sugar made from coconut palm sap. Regular table sugar doesn’t contain any vital nutrients and therefore is just empty calories while coconut sugar because of its minimal processing during production does hold some minerals – like iron, zinc, calcium, and potassium. Also, coconut sugar has a lower glycemic index than regular table sugar (3), which makes him a healthier sugar alternative.

Of course, the star of this chocolate dessert is GUINNESS BEER. It paired so well with dark chocolate flavor and gave richness and beautiful depth of flavor. 

Other pantry ingredients you’ll need:

• Eggs
• Vanilla extract
• Salt

How to make Guinness Brownies

• Prepare and measure all ingredients using measuring cups.
• Place the oven rack in the center position and preheat the oven to 350 F. Spray an 8-inch square baking pan with nonstick coconut oil cooking spray. Line with parchment paper, leaving some hanging out opposite sides like handles. Spray again then set aside.
• In a small saucepan, bring Guinness beer to a boil. Boil for 5 minutes, until reduced by half (you should have 1/3 cup reduced syrup). Set aside to cool.
• In a small mixing bowl, combine together oat flour with cacao powder and salt. Mix and set aside.
• In the microwave or a double boiler, melt dark chocolate and butter/coconut oil until completely smooth. Set aside to cool slightly.
• In a large mixing bowl, whisk coconut sugar, eggs, and vanilla extract. Add melted dark chocolate and Guinness syrup and whisk to combine. Stir in flour and cacao. Keep stirring until the mixture is smooth and glossy. Use the whisk.
• Pour the mixture into a prepared pan. Bake for 30-35 minutes until a toothpick inserted into the center comes out clean. Be careful not to overbake!
• Carefully take out of the pan and place it on a wire rack to cool completely.
• Dust with cacao powder (I use a small fine mesh). Slice and serve (I use a pizza cutter). 
• Makes 9 slices.

Substitutions

• You can use quick oats or rolled oats to make oat flour.  
• You can swap oat flour with whole grain wheat flour or almond flour.
• Swap butter with coconut oil. Make sure to choose organic virgin coconut oil rather than refined versions.
• MAKE IT GLUTEN-FREE: Use certified gluten-free oats / oat flour or almond flour.

Tips for storing

• Keep covered in the refrigerator for up to one week. 
• You can store brownies in an air-tight container or cake carrier.
• HOW TO FREEZE: Place in a zip-lock bag and freeze up to three months. Thaw on room temperature before using.

These dark chocolate Guinness Brownies are ultimate pleasure. Instant mood booster and happiness bringer. Bitter-sweet, dense and absolutely perfect, it’s just what we need sometimes to distract us from bad news and put us in cheerful mood. 

Enjoy!
