Whats better then a peanut butter cookie?? One topped with a Hersheys Caramel Kiss!!! 

Basic PB thumbprint cookie recipe

1 3/4 cup all-purpose flour
1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 cup unsalted butter, softened
1/2 cup firmly packed light brown sugar
1/2 cup granulated sugar
1 large egg
1 teaspoon pure vanilla extract
3/4 cup creamy salted peanut butter

In a medium bowl whisk together flour, baking soda and salt. Set aside.

In the bowl of an electric mixer, beat together the butter and sugars until smooth and blended. Add the egg and vanilla and mix well, scraping down the sides of the bowl. Add the peanut butter and beat well until blended. Scrape down the bottom and sides of the bowl. On low speed, blend in the dry ingredients.

I use a cookie scoop, then push indent with thumb or back of spoon. Bake at 350 for 13-15 mins. While still hot place Hersheys kiss in the indent. 

Turn oven off and return for a min. Once the kiss starts to melt, swirl with the back of a spoon.
