where can i find the orginal m and m cookie recipe in about late 70 s to early 80 s

You can usually find the original M &M cookie recipe in old M&M promotional recipe clippings from the 1960s through the early 1980s, plus recipe archives and vintage cookbook sites that reprint those ads and cards.

Good places to look

• Recipe archive sites that preserve old clippings, especially one that reposts a 1966 TV Guide promo version of the recipe.

• Vintage recipe communities where home cooks share “old school” versions and scans of family clippings.

• M &M-related archived pages that show the classic “Party Cookies” style recipe with butter or shortening, brown sugar, vanilla, eggs, flour, baking soda, salt, and plain M&M’s.

What the old version looked like

The vintage “Party Cookies” recipe was very simple: shortening, brown sugar, granulated sugar, eggs, vanilla, flour, baking soda, salt, and plain M&M’s, baked at 375°F for about 10–12 minutes.

A later archived M&M’s recipe uses a similar structure and adds M&M mini baking bits, which shows how the formula evolved while keeping the same basic cookie style.

Practical tip

If you want the most likely late 70s to early 80s version, look for recipes labeled “Party Cookies” or “Original M&M Cookies,” since that was the common naming style in older promotional printings.

TL;DR: The recipe is most often found in vintage M&M promo clippings and recipe archives, and the classic version is a basic sugar cookie with plain M&M’s.
