Best Boozy Baileys Oreo Brownies

Oh yeah, it’s definitely time to treat yourself, and what could be more decadently delicious than these Baileys Oreo brownies? So much gorgeously fudgy chocolate brownie, with that classic Oreo cookies and cream taste and the smooth kick of Bailey’s Irish Cream.

These Baileys Oreo brownies are the perfect grown-up party pleaser, and also make an excellent DIY gift for Christmas and the Holidays. Something about them just reminds me of a boozy cookies and cream hot chocolate in bar form, and what’s more festive than that? Probably a lot of things, but I still think these are great for gifting!

You could even make a little Christmas gift set, packaging up a few heavenly brownie slices with a mini bottle of Baileys, a pack of Oreos and a sachet of instant hot chocolate.

Alternatively, they'd be amazing for grown up dinner parties and picnics. Or just make a batch and eat them all because boozy brownies are the best and you deserve it.

✏️ Making a tasty and easy recipe

It’s no secret that I’m a huge fan of an alcohol-infused bake. These Baileys Oreo brownies just came to my mind as a fully formed idea – I love Baileys Irish cream liquor, I love Oreo cookies and I love hot chocolate, so why not smoosh them all together and go to boozy brownie heaven?

I wanted to create a recipe for brownies from scratch, keeping it simple but also delicious. The addition of the Irish cream in the recipe gives it a super smooth and creamy texture, making it just so tasty! In my opinion, it’s one of the best brownie combinations.

🥘 Ingredients notes

When measuring your ingredients, I always recommend using weights rather than cups where possible for greater accuracy. Accuracy is especially important for the amount of flour used.

Using high-quality ingredients will make a huge difference in the taste of your Baileys Oreo brownies.

I’ve tried using several different brands of cooking chocolate, and you can tell the difference between a cheap brand and good-quality baking chocolate. I use Callebaut dark chocolate for this recipe and it’s delicious!

I also recommend using a decent flour, such as Homepride, Mcdougalls (both good UK brands) or Bob’s Red Mill (a good US brand).

🔪 Equipment notes

I usually use an 8inch (20cm) square tin for these brownies, like this tin from Wilton.

I find it easiest to grease and then line the pan with parchment paper (greaseproof paper), leaving a small overhang over the sides. This way, you can leave the brownies to cool for a few minutes in the tin, then lift the whole square out easily.

I like to use digital scales for weighing my ingredients as it's easier and more accurate than other scales. I'm a fan of these KitchenAid or Salter ones! Weighing your ingredients is much more accurate than using cups and will give you better results.

Where possible, use measuring spoons for your tsp and tbsp amounts.

🍱 Storage

One of the best ways to keep your brownies moist is to seal them in an airtight container and store them in the fridge. These boozy Baileys Oreo brownies should last up to a week in the fridge.

💭 Top tips for success

• For a perfectly soft and gooey brownie, it’s important not to overbake them. You should try to take these boozy brownies out of the oven once they have a slightly cracked top and are still very slightly wobbly in the middle. I do like my brownies pretty fudgy!

• When these bad boys come out of the oven, they’ll be quite soft, but don’t panic! These boozy brownies will firm up as they cool to give that fudgy chewy goodness. If they’re still not firm enough for your liking, you can pop them in the fridge to set further before serving. Something about eating them cold really boosts the sweet mouth joy for me!

♻️ Alternatives and substitutions

If I’m feeling extra decadent, I’ll add in an extra ¼ cup (45g) each of white chocolate chips and milk chocolate chips into the brownie batter before pouring it into the tin and studding with Oreos – adds a nice extra texture and sweetness!

You can also experiment with different Oreo flavours – I’d love to try the double stuffed Oreos or the mint chocolate ones! There’s a whole range of Oreo cookie flavours to choose from, let me know if you’ve tried any fun flavours and how they turned out in the comments below.

Another great alternative is to switch up the flavour of Baileys Irish cream that you use. They also have a great range of Baileys flavours – the salted caramel one is sure to be a winner!

Gluten-free option:

For a gluten-free option, you can swap the plain / all-purpose flour in this recipe for a gluten-free plain flour blend of the same quantity.

I usually recommend a pre-mixed blend such as King Arthur's measure for measure flour or Freee from Doves Farm.

The other ingredients should be gluten-free, but please be sure to check the label on your ingredients just in case!
