Instructions

1. 1
   In a mixer, cream together the butter and sugar.
2. 2
   Once creamed, add the egg and vanilla. Beat until it is smooth.
3. 3
   In a mixing bowl, stir together the flour and baking powder.
4. 4
   Add flour to creamed mixture. Beat on low speed until it is thoroughly combined.
5. 5
   Portion out the dough into round, firm balls. Place on sheet pan. Using the end of a wooden spoon, press down on the dough ball to form wells.
6. 6
   Fill each well with jam. Do not overfill the well, as they will overflow and burn. For the same reason, keep the edges of the dough clean.
7. 7
   Bake at 300°F (160°C) for 22–24 minutes, until it is light golden brown.
