I like this one better than the real one. The advantage of making it yourself is that you can make your baileys as strong as you like.
Recipe from Home Made Winter by Yvette van Boven.
The recipe below is the original recipe. I added some more espresso powder and chocolate syrup to taste.
Mix 200 ml preservable cream, a can of condensed milk, 300 ml Irish whiskey, 1 tablespoon espresso powder and 2 tablespoons chocolate syrup in a blender and mix until well blended.
Pour the drink into clean bottles. You can keep it in the fridge for up to 2 months.
