Hilary Duff stopped into Sprinkles in Beverly Hills on Wednesday with son Luca and a girlfriend to stock up on some tasty treats.

Duff who "especially loved" sampling eggnog frosting shots was "very sweet" to fans who recognized her, an onlooker tells PEOPLE.

Wearing black yoga pants and a white sweatshirt, the actress, 25, ordered a dozen cupcakes including one black and white, one chocolate coconut, one cinnamon sugar, two peanut butter chocolates, one pumpkin, two red velvets, one vanilla milk chocolate, one German chocolate, one triple cinnamon and one chocolate peppermint.

But that wasn't all Duff also made sure to bring home four doggy cupcakes for her pampered pooches. Jennifer Garcia
