Decide your use: cocktails/lattes need a pourable liquid, while baking benefits from thicker sweetness.
Choose the closest option from the list above and swap using the stated 1:1 ratio.
Adjust “strength” only once: if the result tastes flat, add a small pinch of cocoa or a tiny splash more coffee note.
If your swap is thicker than Irish cream, thin with 1–2 teaspoons milk/creamer per 1 serving; if it’s too bitter, balance with a small amount of sugar.
Taste before committing—Irish cream is forgiving, but cocoa/coffee can run bitter quickly if over-added.
