Homemade Baileys Irish Cream is really easy to make without using condensed milk, which is sweetened. This keto baileys copy cat recipe tastes almost identical to the real thing, and you won't need to worry about being kicked out of ketosis from consuming too many carbs.
You can make this Irish cream from any kind of whiskey, so don't worry too much about an Irish brand. I've even made it from spiced rum, and it tastes delicious.
