Shortbread Cookies - Adding PB


My wife used to really like the ghirardelli shortbread cookies, with the chocolate "kiss" in the middle. I haven't seen the mix in years, but stumbled upon this recipe... i made it once, and yeah, it's pretty darn close. but i remember on the box, it gave directions for adding peanut butter to the recipe, which i'd like to do here. Curious about how much to add without losing consistency? I don't want it to be an overpowering PB taste, just a nice note. I was thinking 1/2 cup, probably to be mixed in with the butter, before the rest of the dry ingredients?

thanks, nathan

2 cups unsalted butter , softened
1 cup powdered sugar
1/2 cup cornstarch
3 cups flour
1 teaspoon vanilla extract
1/2 teaspoon salt
semisweet chocolate chunks (or drops) or milk chocolate pieces (or drops)

anyone who wants to try the recipe, here's the directions:

1 Preheat oven to 350°F Line 2-3 cookie sheets with parchment.

2 Cream butter and vanilla with mixer. In a separate bowl, sift together powdered sugar, cornstarch, flour and salt. Gradually add dry ingredients to butter, beating constantly on high until the batter is the consistency of whipped butter (about 5 minutes).

3 Drop dough by heaping teaspoons onto prepared cookie sheets. Bake for about 15 minutes, or until cookies begin to turn golden on edges.

4 Immediately after removing cookies from oven, press one chocolate piece into the center of each cookie. Cool completely.

Nathan, I'm not sure about adding peanut butter to the dough in this recipe. That doesn't mean you shouldn't try it. 1/2 cup seems like a lot to me only because it is going to change the consistency of the dough.

If you added that much pb, you might have to add more flour and then adjust for consistency to make the cookies. I'm worried about the spread of the cookies. You need something to put the kiss in and one 9" flat cookie won't work. Lol :-))

Try it and let us know how it turns out. BTW, I would start with 1/4 cup of pb. Just my thoughts.

p.s. another thought. Decrease the butter by the amount of pb you are using. In other words, think of the pb as butter and substitute the pb for the butter. 1/2 cup pb = 1/2 cup butter. And cream it together. Might work.

Good morning. I thought about your idea. Sooo, I put my culinary imagination to work for you. This is what it said to me.

Tell Nmat, that most likely the peanut butter can be considered a fat. Sooo, why don't we reduce the butter by 4,oz (1/2,cup) & add the 1/2, cup of peanut butter you mentioned in your post. Try it once depending on the taste of your cookie you then can alter the fat somewhat. I think that what I suggested will be in the ball park but it may require some fine tuning. Please let us know if you do this recipe. There are others who will like to try this baked product.

I know you will succeed in this endeaver.

Good luck to you & happy holidays to you as well.

Another option might be to follow Kidpizza's suggestion but start with just a 1/4 cup substitution and enhance with a natural peanut butter extract in conjunction with the vanilla (or subbing for the vanilla).

Another direction to try would be a nut shortbread using ground roasted peanuts, which is all peanut butter is anyway. Again, peanut butter extract would enhance the flavor.

I didn't even think of the peanut butter flavoring from LorAnn Oils, Carol, great idea! Then you could add 1/4 cup pb with the butter and omit the vanilla and add pb flavoring, instead. That would enhance the flavor and really make those cookies something special!

Please, if you try these ideas, come back and let us know how they turn out. It makes some of us (me! :-)).....) crazy when we spend time helping and then we never find out how things went. If it works for you, then I might like to make them!
