Rainbow M&M Frosted Cookie Bars

For the cookies:
Combine Crisco, sugar, milk and vanilla. Beat in egg. Add dry ingredients and combine thoroughly. Add in morsels and m&ms.

Press into bottom of baking sheet (with sides). Bake in a 375ºF oven for about 25 minutes. Center may appear to be a little undercooked; let it rest in baking pan until completely cooled.

For the frosting:
Beat all ingredients together (except gel food coloring) for 5 minutes until fluffy. Add more milk if necessary for desired consistency.

To frost cookie bars with rainbow pattern, open a large (16-inch) decorator bag (I used disposable). Taking your gel food coloring, make stripes from the tip of the bag up 3/4 of the way. Repeat with other colors. Spoon your frosting into the bag carefully, twist the top and secure.

Cut cookie bars into desired-sized pieces. Pipe frosting onto individual bars. The rainbow colors may be more pronounced with the first bars, and become lighter in color with the remainder. Enjoy!
