These easy Baileys Oreo brownies are based on my favourite recipe for homemade chocolate brownies from scratch. 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
This Bailey's cookies n cream brownies recipe calls for the following ingredients:
- Butter: using unsalted lets you control the amount of salt.
- Dark semi-sweet chocolate: use cooking chocolate or melting wafers for ease of melting.
- Eggs
- White sugar: caster or finely ground granulated sugar
- Plain all-purpose flour
- Unsweetened cocoa powder: the baking type (e.g. dutch-processed) not the drinking kind.
- Bailey's Irish cream liqueur
- Oreos
See the recipe card for quantities.
Top tip: For accuracy, it’s best to weigh your ingredients rather than using cups.
♻️ Substitutions/Variations
You can swap the white sugar for golden caster sugar or light brown soft sugar.

📖 Method
- Preheat oven: 180°C / 160°C (fan) / Gas Mark 4 / 350°F
- Melt the butter and dark chocolate, either in the microwave (no more than 30secs at a time) or over a double boiler, stirring until smooth.
- Beat the eggs and the sugar together until light and fluffy, then pour in the slightly cooled chocolate mix, stirring together until combined.
- Sieve in the plain flour and cocoa powder, gently folding into the mix until just smooth, before stirring in the Baileys, mixing till even throughout.
- Pour the brownie mix into a lined 8-inch square tin and spread evenly in the pan before breaking up the Oreos (roughly into quarters) and adding them on top, spacing evenly and pressing in slightly.
- Bake for 25-30mins until the brownie top is lightly cracked, with only a slight wobble in the middle. Allow the brownies to cool before cutting them into squares.
💭 Top tips
- Grease and line the brownie pan with parchment paper (greaseproof paper), leaving a small overhang over the sides to lift out easier after baking.
- For a soft fudgy brownie, it’s important not to overbake them. Take these boozy brownies out of the oven once they have a slightly cracked top and are still slightly wobbly in the middle.
- These Bailey's Oreo brownies will firm up as they cool to give that gooey chewy goodness. If they’re still not firm enough for your liking, you can pop them in the fridge to set further before serving.
