The superstar gal pals even learned to make pasta from scratch by taking a class with the Culinary Institute of America.

Stylist Leslie Fremar and makeup artists Gucci Westman and Loni Vigi also came along for the fun.

"What an amazingly delicious, educational, and ridiculously FUN time I had with these awesome ladies!!!" Diaz posted on her Instagram.

The group, which reportedly stayed at the Meadowood resort, also stopped by the exclusive Opus One winery and Maisonry during their wine country visit.

And perhaps their girl trip is becoming an annual event -- the three previously showed off their bikini bods in Mexico last March.
