Mudslide with Peanut Butter Whiskey

My buddy Dave swore he didn't like peanut butter in drinks, then went back for a second Mudslide with Peanut Butter Whiskey before he'd finished the first. The Skrewball does sneaky things to a frozen mudslide, it tastes like a chocolate peanut butter cup that someone spiked. The Ninja Slushi gets it thick and scoopable, closer to a milkshake than a slush, which is exactly what you want here. One tip from experience: go easy on the whiskey pour or it won't freeze up right and you'll be drinking warm soup. This one's 21+, obviously.

Tips

  • Pour your liquid base into the Ninja Slushi bowl at room temperature; the machine will chill and churn it into slush over 20 to 60 minutes depending on your room temperature and ingredient ratios.
  • If your slush isn't scoopable after an hour, your base might be too thick or your machine too warm; adding a bit more water thins it out so the churning works better.
  • Scoop and serve immediately when the consistency looks like wet snow; if it sits too long after the machine stops, it'll refreeze into a harder block.

Variations

  • Swap the peanut butter whiskey for regular bourbon or omit it entirely for a booze-free mudslide slush that's great for non-drinkers.
  • Use chocolate syrup instead of the Mudslide Mix and stick with the vanilla soft serve mix for a simpler homemade mudslide flavor.

FAQ

Can I use a different whiskey instead of Skrewball?
Yes, but you'll lose the peanut butter flavor; regular whiskey, bourbon, or Irish whiskey all work, though you might add a splash of peanut butter liqueur or syrup if you want that taste back.
What if my slush won't freeze or isn't thick enough?
The machine might be in a warm room, or your base has too much water; try reducing water by a quarter cup and give it more time to churn, or move the machine to a cooler spot.
Can I make this lighter or less sweet?
Cut back on the soft serve mix and add more water to reach the same total volume, or skip part of the Mudslide Mix; you'll get a thinner, less sugary slush.
How long can I store the finished slush?
Once dispensed, eat it within 15 to 20 minutes; if it refreezes solid in the bowl, you can scoop it out and eat it like ice cream, though the texture won't be as fluffy.
