Split Second Cookies

3/4 cup unsalted butter
2/3 cup sugar
2 tsp vanilla
1 egg
2 cups flour
1/2 tsp baking powder
1/4 tsp salt (if you use salted butter, leave this out)

Cream together butter and sugar. Stir in vanilla and egg. Stir in flour, baking powder, and salt until dough forms.

Divide dough into 4 parts. Roll each part into a 3/4-1 inch thick log. Place the 4 logs onto un-greased cookie sheets and flatten each to about 1/4 inch thickness. Make an indentation down the center of each strip, starting about 1/4 inch from each end. Fill each indentation with jam of your choice.

Bake 15-20 minutes at 350 degrees. Cookies should be golden brown. Let cool slightly before cutting on the diagonal into individual cookies.
