Jennifer Garner's mom, Pat Garner, is schooling her during an adorable cameo on her hilarious Instagram video series "Pretend Cooking Show." On Wednesday, the mother-daughter duo twinned in matching customized sweaters as they made a very nostalgic dessert, chiffon pie! "We've got to reveal our sweaters! 'I'm hardly ever without buttermilk,'" Jen says as she reads their matching tops. "A quote made famous by Pat Garner Herself." The "Yes Day" star worked hard to follow the instructions while her mom supervised. "Well this can't go in there right now. We're gonna whip the eggs in here," Pat told her daughter who replied, "Oh, darn. Pardon me." "Summertime for the Garner Girls: there was always a garden. Farmers markets were king. We ate dinner on the deck my dad built. And for dessert, we had mom’s chiffon pie," the mom of three adorably captioned the heartwarming video.
