In a separate bowl, stir the flour, baking powder, and salt.
2 ½ cup flour, 1 teaspoon baking powder, ½ teaspoon salt
Add the flour mixture to the butter mixture a third at a time, mixing between additions, until the flour is combined.
Preheat the air fryer at 350 degrees F for 3 minutes.
Use a dough scoop or spoon to make tablespoon size balls.
Flatten the cookie balls slightly with your fingers, pushing them down until they are about 1/2 inch thick. Then use a teaspoon or your thumb to make a well in the center. Fill each well with a teaspoon of jam.
1/4 cup jam
Once preheated, add a parchment paper liner to the basket. Place the thumbprint cookies on the parchment paper, keeping them about 1 inch apart. Make multiple batches if necessary.
Bake for 5-8 minutes or until set and golden brown.
Remove from the air fryer and let them cool in the basket for 5 minutes before removing them to a wire baking rack to cool completely.
Optional: Dust the tops of the cookies with powdered sugar for a seasonal snowy look.
1/8 cup confectioners sugar
Notes
One Dough, 4 Cookies
Use this same cookie dough to make other air fryer cookie recipes! See here for all the classic cookies you can create and make some festive treats for the holidays.
This dough freezes well. Divide it into 4 parts, wrap each tightly in plastic wrap and freeze. I can make 8-12 cookies per dough portion. Put the frozen cookie dough in the refrigerator the night before you plan to make it, and let it thaw.
