Peanut Butter Icing / Frosting for Cookies

READY IN: 5mins
Recipe by Random Rachel

Thick frosting that dries sort of shiny - perfect for cookies that need to be stacked and taken somewhere. I like the recipes I've seen for plain icing that dries, and played with it to make a peanut butter version since my father in law is always asking for peanut butter cookies. Prep time doesn't include frosting the cookies, which will vary depending on how detailed you get. I iced 32 (2-3") cookies.

The flavor is really good on the icing. Reminds me of peanut butter fudge. I put it on peanut butter chocolate chip cookies and they taste great. I gave it 3 stars because the icing never hardened up. It was still sticky after an hour and a half. I followed the directions exactly, so I'm not sure why it didn't harden. Needless today, I couldn't "stack" them as I hoped :-( So I let them harden for another half hour and they are starting to get better. My icing was pretty thin to begin with, but I think you will need to let them sit for 3 hours to get the desired effect.

Ingredients Nutrition


  1. Measure everything into mixing bowl. You want a thick pasty frosting, so start with just a little milk, and add enough to get a spreadable consistency. Beat well with a fork. Add additional corn syrup or milk if needed.
  2. You can separate the icing into bowls and add different colors if desired.
  3. Spread on cookies with butter knife. Allow to dry for about an hour, longer if you used a heavy layer.
