Khloe Kardashian: My Cheesecake Is No Lie ... I Can Prove It

Khloe Kardashian might lie about baking pies, but she's a regular Betty Crocker when it comes to whipping up a cheesecake.

Khloe posted a pic of a cooked cake and says there's proof SHE made this because she recorded the whole thing for a "Cooking with Koko" segment.

We broke the story ... Khloe tried to pass off pies from an L.A. bakery, Sweet Lady Jane ... as her own for Thanksgiving dinner.

As for the umm ... flaws in the cheesecake -- she blames "munchkins" for nibbling before the pic, but preemptively told her haters ... "It's a f***ing cheesecake. Grow up."
