What makes this mudslide “tangy”?
A small amount of plain Greek yogurt (or buttermilk) adds gentle acidity. You do not taste “yogurt.” You taste a cleaner, brighter mocha flavor.
Can I make it without a blender?
Yes. Make the on the rocks version: shake everything in a cocktail shaker with ice, then strain into a glass over fresh ice. This recipe does not use ice cream, so you are not missing anything.
Is it super sweet?
Not compared to most mudslides. The cocoa, coffee, and tang keep it balanced. If you want it sweeter, add 1 to 2 teaspoons chocolate syrup or simple syrup and blend or shake again.
Is this a strong cocktail?
Yes, it leans bold. If you want a lighter pour, use 1 ounce vodka, 1 ounce coffee liqueur, and 1 ounce Irish cream (total) for the whole batch, then top up the blender or shaker with an extra splash of half-and-half to keep it creamy.
Can I make it alcohol-free?
Absolutely. Swap the coffee liqueur for strong cold brew and the Irish cream for Irish cream-style coffee creamer or a mix of cream plus a little vanilla. You still get the vibe.
Can I use vanilla ice cream?
You can, but it turns this into more of a milkshake situation. If you go that route, reduce the half-and-half and add an extra teaspoon of cocoa powder or a splash of espresso to keep the bold edge.
Will the yogurt curdle or get grainy?
It should not curdle in a cold, creamy drink like this, but texture can vary by brand. For the smoothest result, use whole or 2% Greek yogurt, blend thoroughly, and serve right away. If it ever tastes a little grainy, a longer blend usually fixes it.
