Peanut Butter and Jelly Thumbprint Cookies

Preheat the oven to 350°F. Line two baking sheets with parchment paper.

In a large mixing bowl, cream the butter with an electric mixer. Add the peanut butter and mix until it's just combined with the butter. Add the granulated sugar and brown sugar, and mix until well creamed together with the butters. Scrape the sides of the bowl as needed. Add the egg and vanilla and mix until just combined. Add the baking powder, salt and flour and mix just until the last of the flour disappears into the dough.

Roll the dough into balls that are about 1 1/2 tablespoons in size. Add some granulated sugar into the measuring cup you used for the flour. Roll each ball in the sugar and place them on the prepared baking sheets. Use a fork to press the traditional crisscross design into the cookies. Use you thumb to press an indent into the center of each cookie over the crisscross, and add about 1 teaspoon of the preserves to each.

Place the cookies on the prepared baking sheets about 2 inches apart. Bake for 9 to 11 minutes, rotate pans halfway through baking. Bake until outer edges start to turn golden brown. Let the cookies cool 5 minutes on the baking sheet, and then transfer to a cooling rack to cool completely.

Enjoy as soon as they're cool enough to eat. Store leftovers in an airtight container at room temperature for up to 5 days.
