♻️ Substitutions / Variations
You can swap the cornstarch (a white fine powder called cornflour in the UK and other places) for more plain all-purpose flour of the same quantity. Cornstarch gives that lovely shorter texture for chewy Baileys irish cream cookie bars though!
For a more caramel flavour, you can swap the white sugar for all light brown sugar. For less of a caramel hint, you can swap the brown sugar for all white sugar.
You can use any flavour of Bailey’s Irish cream liquor for your Baileys irish cream bars.
You can swap your white chocolate chips for milk or dark chocolate (semi-sweet) chips instead.
Alternatively, swap half of the white chocolate chips for chopped pecans for an added crunch.
To use a 9-inch square tin instead of an 8-inch tin, you don’t need to change the recipe. Cook for 5mins less time. You’ll have a slightly thinner Baileys blondie.

💭 Top tips
- Leave a small overhang of parchment paper so it’s easy to lift your irish cream blondies out of the tin after baking.
- Beat your sugar-butter-egg mixture thoroughly until it’s smooth and thickened. This will give your irish cream bars a lovely soft chewy texture.
- You’ll know your Baileys blondies are cooked when they’ve turned a light golden colour on top and there’s only a slight wobble left in the middle.
- Let your Baileys blondies cool in the tin before removing them and cutting into squares. This stops them from breaking when you try to lift them.
- For neater Baileys squares, place your blondies in the fridge for 30mins – 1hr before slicing. Use a sharp knife and wipe the blade between cuts for the ultimate neatness.
