Still ruminating about what to make your mom for Mother's Day dessert? I'm happy to tell you that you still have time to make a cool and easy ice cream cake that will delight both your mama and whomever else happens to be gathered around your Mother's Day table. You don't have to tell anyone that it's a super-fast concoction of your favorite vanilla ice cream, chopped up peanut butter cups, chopped pretzels and chocolate sauce. I won't if you won't.
