Peanut Butter Cookies with Blackberry Jam

adapted slightly from Giada

Ingredients

1 cup all-purpose flour
1/3 cup unsweetened cocoa powder
1/2 teaspoon baking soda
1/8 teaspoon fine sea salt
 1 stick (1/2 cup) unsalted butter, at room temperature, cut into 1/2-inch pieces
3/4 cup creamy peanut butter, at room temperature
3/4 cup sugar, plus 1/4 cup
1/2 packed cup light brown sugar
1 egg, room temperature, beaten
1 teaspoon pure vanilla extract
1/4 cup blackberry jam {I had raspberry on hand, so that's what I used}


Directions

1. Put an oven rack in the center of the oven. Preheat the oven to 375 degrees F. Line 2 baking sheets with parchment paper. Set aside.

2.  In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
In a stand mixer, fitted with the paddle attachment, beat the butter, peanut butter, 3/4 cup of sugar, and light brown sugar together, scraping down the sides of the bowl as needed, until smooth, about 30 seconds. Add the egg and vanilla extract and mix until blended. With the machine running on low speed, gradually add the flour mixture until incorporated.

3. Put the remaining 1/4 cup of sugar in a small bowl. Form the dough into 1/4 cup-size balls-split in half- and roll in the sugar. Arrange 8 balls of dough, evenly apart, on each baking sheet. Using a round 1/4 teaspoon measure, or the thin end of a wooden spoon, make a hole in the center of each ball of dough, about 1/2 to 3/4-inch deep. Fill a ziploc bag with jam, cut one corner off, and squeeze about 1 tsp. jam into each hole. Bake for 11 to 14 minutes until the dough has spread and the surface of the cookies are crackled (mine were ready at 11). Cool for 5 minutes on cookie sheet and transfer to a wire rack to cool completely, about 20 minutes.
