Guinness Chocolate Brownies

I have spent the better part of the last couple weeks of my life on these brownies, no joke. I wanted the most perfect version of a guiness brownie to share with you.

But before I dive into all that, I have a confession. Get ready.

I don’t like beer.

I know, I know. How can I post a recipe with beer in it when I don’t like beer. I can’t explain it except to say that it’s my dad’s fault. I clearly got my taste buds from him – he also does not like beer. It’s a thing and he passed it on to me. I have tried so many times to like it. It just won’t work.

So I fully expected to not like these brownies. I have a coworker who loves Guiness like I love cake, so I knew he’d help out with the taste testing.

Crazy thing is, I’m super in love with these brownies. I can taste the Guinness, but it mostly just enhances the flavor of the chocolate in the best way possible. Seriously amazing. And they seem to get moister the second or third day.

So back to the whole testing these thing. I started with these Quick and Easy Brownies. They are the jam, and pretty much everyone that tries them loves them. So I started with those.

But oh my, the bubbles in Guinness! The first version was basically like chocolate cake. No good.

I proceeded to make like 6 or 7 more versions – I lost count. Messing around with the amount of Guinness, eggs and some other ingredients to get the perfect amount of fudgy and cakey. I am totally in love with the final texture of them.

I also wanted them to have plenty of Guinness flavor. Truth is, I was never totally able to please my Guinness loving coworker. I added almost an entire beer and he still didn’t think it tasted that much like Guinness. He and his family (and everyone else) loved the brownies, but I decided I’d have to drown a brownie in Guinness before he’d think it tasted enough like it. Craziness.

I still think they taste like Guinness, but maybe I’m just sensitive to beer taste. I guess you’ll just have to make them and decide for yourself. 🙂 They’re totally worth it.

FAQs

What happens if you use milk instead of water in brownie mix? ›

One change is to use milk or heavy cream instead of water. This change will make brownies more moist and gooey since milk is more fatty and flavorful than water. A second change is to use butter instead of oil. For similar reasons to using milk, butter adds a rich and more decadent quality to the batter.

What happens when you add extra eggs to brownies? ›

They give brownies a lighter, drier, and more cake-like texture. If you prefer this over the chewy variety, then go ahead and crack in that additional egg. On the other hand, too many eggs will yield brownies that are hard, heavy, and tough.

What can I add to brownie mix to make it better? ›

Vanilla extract – Pure vanilla extract adds rich flavor to brownies. Eggs – Most brownie mixes call for one whole egg. Adding one large egg plus an extra egg yolk gives brownies an ultra fudgy texture.

How much milk do you put in brownie mix? ›

What happens if you use butter instead of oil in brownies? ›

the butter brownies actually had a fudgier texture. they were softer, and they really just melted in your mouth. they also had that shiny crust and just better flavor, whereas the oil brownies were actually chewier.

Do brownies taste better with milk or water? ›

Brownie recipes traditionally call for water as it serves as a neutral liquid that hydrates the dry ingredients. However, using milk instead of water can impart a creamier texture and richer flavor to your brownies. The milk's fat content adds a smoothness that water cannot provide, resulting in a more indulgent treat.

Should you beat eggs before adding to brownie mix? ›

The eggs should be beaten until roughly hom*ogeneous; that is, there should be no "pieces" of unmixed egg white left. (If left in, those pieces would cook and harden, leaving you with, essentially, pieces of boiled egg in your brownies.)

What happens if I use 1 egg instead of 2? ›

Half the recipe and make half as much. Eggs are important in adding “loft” and lightness to the finished product. As they batter cooks, the eggs heat up and release steam, and the steam is what makes the air bubbles in the final product. Half as many eggs as the recipe calls for CAN make a dense unpleasant product.

Do you beat eggs before adding to brownie mix? ›

Cookbook author and food stylist Jerrelle Guy might have given away the secret: In an article for The Kitchn, Guy suggests the secret to a "glossy" and lifted brownie — like the ones you see in bakeries and restaurants — is to beat the eggs and the sugar together for 10 minutes before adding additional ingredients.

How do you doctor up boxed brownie mix? ›

How much butter instead of oil in brownies? ›

It couldn't be easier to substitute butter for oil using a 1:1 ratio. This should work with olive, canola, vegetable, and coconut oils. Simply melt and cool the butter to room temperature, then continue with your recipe. (If the recipe calls for ½ cup oil, use ½ cup melted and cooled butter.)

How to jazz up box brownies? ›

Add a teaspoon of instant coffee or espresso powder. Throw in a handful of nuts—pecans, walnuts, macadamia, whatever you have on hand. Scoop in a palmful of dried or frozen fruit. Add an extra splash of the top-shelf vanilla extract, or a dab of vanilla paste, or a dash of vanilla powder, to the batter.

Should brownie batter be thick or runny? ›

The ideal consistency of brownie mix is thick and gooey, similar to a thick cake batter. When you mix the ingredients together, the batter should be smooth and free of lumps, with a slightly sticky texture. This consistency is important for achieving moist and fudgy brownies that are rich in flavor.
