“Auntie knows the way to her heart #BaguetteIsBiggerThanSheIs,” Hilary’s sister Haylie Duff captioned the cute snapshot.
Haylie also posted a photo of Hilary’s 5-year-old son Luca enjoying the delicious baking.
“The baguette warriors… and their biggest fans,” she wrote.
Recently, the Younger star, who turns 30 on Thursday, shared a selfie with her son.
“[Heart] captured,” the singer-actress Instagrammed the image.
