Is a Mudslide better blended or on the rocks?
Blended is dessert-in-a-glass. On the rocks is more like an iced coffee cocktail. If you want thick and frosty, go blended. If you want quick and sippable, build it over ice with a splash of cream.
Quick on-the-rocks ratio (1 drink): 1 ounce vodka + 1 ounce coffee liqueur + 1 ounce Irish cream. Shake with ice (or just stir), strain over fresh ice, and add 1 to 2 ounces milk or cream if you like it softer.
How strong is this drink?
This blended version is a medium-to-strong dessert cocktail. With typical ABVs, it works out to about 1.5 US standard drinks per serving (since the full batch is roughly 3 US standard drinks), and that can shift a bit depending on the brands and your pour. It still drinks like a milkshake, which is exactly why it can sneak up on you.
If you want it lighter, reduce the vodka to 1 ounce total (for the whole batch) or add an extra scoop of ice cream.
Can I make it without vodka?
Yes. Skip the vodka and add 1 to 2 ounces milk or half-and-half (or cold brew for extra coffee flavor). You will still get the Irish cream and coffee liqueur vibe, just softer.
How do I make a non-alcoholic Mudslide?
Easiest swap: Use an Irish cream style non-alcoholic creamer (brand-dependent), and replace the coffee liqueur with 2 to 3 tablespoons strong cold brew plus 1 to 2 tablespoons chocolate syrup.
DIY option (no special products): In the blender, replace the Irish cream and coffee liqueur with 3 tablespoons half-and-half, 2 tablespoons sweetened condensed milk, 2 tablespoons strong cold brew (or 1 teaspoon instant espresso dissolved in 2 tablespoons water), 1 tablespoon chocolate syrup, and 1/2 teaspoon vanilla. Then blend with the ice cream and ice as written.
What can I use instead of vanilla ice cream?
Chocolate ice cream makes it extra rich. Coffee ice cream makes it taste like a grown-up frappé. Dairy-free vanilla works too, but you may need a bit less ice since some plant-based ice creams freeze harder.
My Mudslide is too thick. How do I fix it?
Add milk one tablespoon at a time and blend again. Blend about 10 seconds before deciding to add more.
My Mudslide is too thin. How do I fix it?
Add another small scoop of ice cream or a few ice cubes and blend until smooth.
Any party prep tips?
Yes. For low-stress hosting, pre-measure the vodka, coffee liqueur, and Irish cream into a jar and keep it in the fridge. Pre-scoop the ice cream onto a plate or tray and freeze it. When it is go time, dump, blend, and serve. Mudslides wait for no one.
