Kourtney Kardashian didn't have to go over the river and through the woods to get to her grandmother's house, and wasn't looking back at Younes Bendjima either.

Kourt was spotted visiting her nana, Mary Jo Shannon, in Calabasas Wednesday -- where the Kardashian klan relocated the family matriarch from her old home in La Jolla. As you can tell, Kourtney seems to know her way around the crib ... gate code included.

She's clearly not thinking about her now-ex, Younes, on the heels of their split -- and why should she? There's grandma-made cookies to be eaten and stories to be heard.
