Ingredient highlights
- Baileys Irish Cream: Adds a smooth, creamy flavour that pairs perfectly with chocolate. Irish cream-flavoured coffee creamer can be used for a non-alcoholic version.
- Cocoa powder: Use unsweetened cocoa powder for a rich chocolate flavour. Dutch-process cocoa works well too.
- Cold eggs: Help create a dense, fudgy brownie texture instead of a cakey crumb.
- Chocolate chips: Add extra richness and pockets of melted chocolate throughout the brownies.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements. Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.

Recipe FAQs

Absolutely. Chopped pecans or walnuts work especially well with the chocolate flavour.
The centre should no longer look jiggly, and a toothpick inserted should come out with a few moist crumbs.
Yes. The brownies are still rich and fudgy on their own, but the frosting adds extra flavour and indulgence.

- 2 – 4 tablespoons Baileys Irish Cream

Instructions
For the Brownies
- Preheat the oven to 180C/350F/Gas 4. Line an 8×8-inch square baking pan with parchment paper and set aside.
- Place the butter, sugar, cocoa powder, and salt into a large microwave-safe bowl and heat for 30 seconds. Stir well, then continue heating in 30 second intervals (stirring after each one) until combined and very warm/hot to the touch.
- Add the eggs and mix well until combined. Mix in the vanilla and Baileys Irish Cream.
- Fold in the flour until fully combined, then fold in the chocolate chips.
- Pour the batter into the prepared pan and spread out evenly.
- Bake for 35 – 40 minutes, or until the centre is no longer jiggly and a toothpick inserted comes out almost clean with a few moist crumbs.
- Allow to cool completely in the pan on a wire rack before frosting.
For the Frosting
- Using a handheld or stand mixer fitted with a paddle attachment, beat the butter until creamy – about 2 minutes.
- Add half of the icing sugar and beat until combined. Add the remaining sugar and beat until combined.
- Add the Baileys Irish Cream and beat until light and fluffy.
- Spread the frosting over the top of the cooled brownies, top with sprinkles, then slice and serve!
