Peanut Butter Icing

It’s peanut butter time again….

Peanut Butter Cut Out Cookies this time with Peanut Butter Icing!

I wasn’t sure that the peanut butter icing would set up firm like other glaze icings I make, so this was for sure trial and error.

Now since I was taking these cookies with me on a fun Avocado Day with Mimi Mimi Avocado,  Laura of Family Spice, Rachael la Fuji Mama her sister in law Kristen and Allison Sushi Day and her handsome guy Son.  I wanted to be sure I could package them up. I didn’t want the icing to be soft and since peanut butter has oil in it, I wasn’t sure if they would set up enough or if the icing would remain soft.

Well I’m so glad I tried it…..because it worked.

Peanut Butter Icing
  • 3 cups powdered sugar
  • 2-3 tablespoons water
  • 1 tablespoon corn syrup
  • 2 tablespoons peanut butter
  • 2 teaspoon vanilla extract
  1. Beat the powdered sugar with water adding the water, corn syrup, peanut butter and vanilla, until it's smooth and creamy. Add more water or powdered sugar to get the consistency you need for piping. I had mine fairly thick, which does make it harder to pipe with but I didn't want it to be runny and wet and not firm up.
  2. Pipe onto cookies and allow icing to dry at least 12 hours, 24 is best if you will be stacking them on top of one another or wrapping them.

Since I never seem to allow a lot of time, I was so hesitant that the icing would set up by the next morning, I iced the majority of the cookies with….

A chocolate peanut butter icing. I knew it would set up. I used my chocolate glaze icing  mixed with 8 drops of Loranns Peanut Butter Flavor. So they didn’t get to try my new icing, but many others did over the weekend and it was a big hit. I will have to make it up next time I head out with these food bloggers next time!

I will be more patient, I will be more patient, I will be more patient!!! LOL, well I hope to at least! Then all the cookie would have had Peanut Butter Icing…oh well, next time.

Oh how I love peanut butter, if you do too you may like these other yummy treats.

    Looks delicious! I don’t make a lot of desserts with peanut butter, but peanut butter cookies are one of my sons favorites. One of the most amazing desserts I have had in my life was the Peanut Butter Semi Fredo at Gramercy Tavern in New York.

    This sounds and looks so good!! I love peanut butter fudge and peanut butter cookies. I am sure I will LOVE peanut butter icing spread on cookies.

    I’ve pinned this to make during the summer!

    Totally not what I was expecting when I saw the title in my reader. How smart are you to come up with this PB icing that sets up?!!

    Do your cookies get dried out when you have to leave them out that long to let icing dry? This is why I’ve never made sugar cookies with the kind of frosting that has to set–I’m super paranoid about drying out my cookies and usually wrap them up as soon as they’re cool. Anyway, this is very cool, I love the idea of pb sugar cookies with pb icing!!

      No the cookies don’t dry out. The icing actually keeps the moisture in the cookies. Before icing if you think the butter will rise up and interfere with the icing, allow cookies to set up for a day. Then ice them and then allow the icing to set for 24 hours before packaging. No the cookie won’t go stale. I worried about that in the beginning. Place all the cookies on baking sheets so the bottoms don’t get air flow under them. I don’t leave the cookies on cooling racks. That would allow air to surround the cookie and then I’m sure you’d get a dryer result. Hope that’s helpful. Let me know if you have any other questions.

        That is very helpful! I’m so glad to know this, now I won’t be afraid to use this icing! I would have left them on cooling racks so I also appreciate your tip on putting them on a baking sheet. Thank you!
