Preheat oven to 350°F (175°C) and line 1 or 2 baking sheets with parchment paper.
02 -
In a medium bowl, whisk together all-purpose flour, additional flour, and salt until evenly mixed. Set aside.
03 -
In a large mixing bowl, beat softened butter, creamy peanut butter, brown sugar, and powdered sugar until light and fluffy. Add egg and vanilla extract, mixing well until fully incorporated.
04 -
Gradually add flour mixture to the wet ingredients, mixing on low speed just until a cohesive dough forms.
05 -
Portion dough into balls about 1 inch in diameter. For classic blossoms and thumbprints, roll each ball in granulated sugar. For crinkle cookies, first roll in granulated sugar, then in powdered sugar. Arrange on prepared baking sheets spaced 2 inches apart.
06 -
If making thumbprint cookies, use your thumb or a wooden spoon handle to make a deep indentation in the center of each dough ball.
07 -
Refrigerate cookie trays for approximately 10 minutes while preheating to prevent spreading.
08 -
Bake cookies for about 12 minutes, or until just set and lightly golden at the edges.
09 -
For blossoms, immediately press a chocolate kiss into the center of each cookie while hot, applying gentle pressure. For crinkles, leave plain. For thumbprints, re-indent if necessary.
10 -
Let cookies cool on the baking sheet for 10 minutes, then transfer to a wire rack to cool completely. For thumbprints, fill centers with jam or preferred filling when fully cooled.
