No-Churn Peanut Brittle Ice Cream
This ice cream is dead-simple, but plan to make it a day ahead: The salty peanut butter slows down the freezing. It's soft but edible at 8 hours, fully scoopable at 24.
If you can’t find peanut brittle at the supermarket, check CVS or Walgreens; drugstores often carry it. Crush brittle in a heavy-duty zip-top plastic bag with a mallet or rolling pin.
