1/2 c. butter
1 c. brown sugar, firmly packed
1 tsp. vanilla
1 egg, unbeaten
1/2 c. sesame seeds, toasted and cooled
1 c. all purpose flour
1/4 tsp. salt
1/4 tsp. baking powder

Cream butter, sugar and vanilla. Beat in egg. Stir in sesame seeds. Add dry ingredients and mix well. Refrigerate 1-2 hours before baking because dough is soft. Drop in small ball like rounds, 3 inches apart on lightly greased baking sheet. Bake 8-10 minutes at 375 degrees. Dough will spread and puff up while baking, then shrink. Let set a minute or so before removing from pan.
