Thumbprint-Jam Cookies

Preheat oven to 350 degrees F.

Using an electric mixer, beat the brown sugar, butter and vegetable oil until creamy (about 1 minute). Add vanilla and egg, continuing to beat until thick and creamy.

Meanwhile, in a separate bowl, stir together flour and salt. Slowly add this to the creamy mixture, beating the mixture (or stirring by hand) on low until fully combined.

Roll into 1-inch balls and place on ungreased cookie sheet. Press thumb into middle of each ball, making a deep indent. Using a small spoon, place 1/2 teaspoon of the jam or jelly into each indentation.

Bake for 15-18 minutes, until cookies are golden and jam is melted.
