PB and J Thumbprint Cookies

Directions

1. Preheat oven to 350º. Cream 1/2 cup butter and 3/4 cup brown sugar. Add 3 tablespoons granulated sugar until fully combined, about 30 seconds. Beat in 1 egg, 1/2 teaspoon vanilla, and 2 tablespoons milk. In a separate medium size bowl, combine 1 1/2 cups flour, 2 tablespoons corn starch, 1 teaspoon baking soda, and a pinch of salt . Stir with a fork until combined. Add flour mixture to wet ingredients, a little at a time, until fully combined. Mix in 1/2 cup peanut butter. Using a small ice cream scooper, scoop dough onto a cookie sheet lined with parchment paper. Using your hands, form each scoop into a ball. Refrigerate the dough for 1 hour. Bake 10-12 minutes. Let the cookies cool for 1 minute. Using the back of a teaspoon or your thumb, create an indentation in the middle of the cookie. Fill the indentation with about 1 teaspoon of jelly.
