Scottish Oat Wedges

3/4 c. butter, softened
1 tsp. vanilla extract
2/3 c. packed light brown sugar
1/4 c. all-purpose flour
3 c. old-fashioned oats

In large bowl beat butter, brown sugar and vanilla until fluffy. Beat in flour and half of the oats until well mixed. Using wooden spoon or by hand work in additional oats until dough just holds together. Press mixture into ungreased 9-inch round baking pan. Using a knife divide dough into eight wedges without cutting all the way through to bottom of dough. Bake in preheated 350° oven until golden brown, about 15 minutes. Let cool in pan, then cut into wedges.
