"Grandma called for two-and-a-half cups of sugar. That is so much sugar!"

So begins Jennifer Garner's latest installment of her "Pretend Cooking Show" on Instagram, Thanksgiving Edition.

This time around, Garner is taking on a recipe near-and-dear to her heart, Grandma Exie Mae Garner's Sweet Potato Pudding. Quickly realizing that Grandma knows best, Garner ditches her efforts to cut back on the recipe's sugar and adds another cup of the sweet stuff to satisfy the full measurement, yes, that's a whopping two-and-a-half cups.

"Happy Thanksgiving! #PretendCookingShow was invited to share a family recipe with the one and only #BarefootContessa—easy as pie—Exie Mae's Sweet Potato Pudding," she begins her caption of the playful video clip. "Now my darling @inagarten has been kind enough to share Grandma's pudding on her special Thanksgiving episode! In case you missed it last night on @foodnetwork— the full episode is on IGTV," she continues, adding, "There are tons of ways to make this less rich—but is this really the week to go crazy?"

This isn't the first time Garner has shown her admiration of Garner in her "Pretend Cooking Show." In fact, the first-ever episode featured Garner transforming Garten's honey white bread into oh-so-cute "bread men." (Think gingerbread men, but swap bread rolls for cookie dough.)

Much to our relief, Garner was kind enough to share the full recipe, leaving her fans with a sweet send-off: "Thank you, Ina, for having me. And thank you, Grandma, for a recipe that tastes like you made it and is everything cozy and delicious about Thanksgiving."
