Chris commented on the cookies pictured in a previous post, M&M Shortbreads, but didn't find the recipe online. It's a funny thing about that recipe. I noticed it on a package of M&Ms some years back and gave it a try. Grandson Jack was here at the time, and we liked them. Fortunately I saved the recipe and now have it on my iPad because I've never seen it again, nor have I found it on M&Ms website (www.mms.com). So, here it is:
1 cup butter (no substitutes, i.e., don't use margarine, Crisco, etc.)
1/2 cup sugar
1 tsp vanilla
2 cups flour
1/4 cup cornstarch
1 to 2 cups M&Ms
Preheat oven to 300 degrees
Mix butter, sugar and vanilla thoroughly. Gradually blend in flour and cornstarch. (If dough is too dry to work with, add milk one tablespoon at a time until desired consistency is reached.) Add one cup M&Ms. Gently flatten each cookie with a flat-bottomed drinking glass dipped in sugar to prevent sticking. Press in additional candies to decorate.
Bake 25-30 minutes per pan. Cool 5 minutes before removing. (About 3 dozen cookies)
Since this recipe isn't on the M&M website, I can only conclude that for some reason it wasn't successful. Previously I haven't had difficulty with it, but when I baked them the other day, I used Lucerne (Safeway brand) butter which was still hard after having sat on the counter for 24 hours. The dough was very stiff, and I had to add two tablespoons of milk to make it workable and probably should have added three. It takes some time to bake these cookies and then it's a small batch. Still, if you like shortbread cookies and M&Ms, and you've had some experience in the kitchen, I think you'll like these cookies.
M&Ms celebrated its 75th anniversary in 2016, having come on the market in 1941. Mike confirms that he doesn't remember a world without M&Ms.
As an aside, 20 years ago I bought a string of M&M Christmas lights. I liked them so well that I bought another string for myself and sent strings to the existing grandchildren as well. I love those lights to this day. In fact, the light string gave out, so I removed the plastic "M&M" caps and placed them over a new string of white lights. They stay on well enough when the string is hooked into the kitchen window.
If we didn't have plastic, I wouldn't have those M&M lights. KW
