Step 1

Preheat oven to 350°F. Grease a 9x13 baking pan.

Using electric mixer on medium speed, beat butter and brown sugar until light and fluffy. Add eggs, one at a time, mixing well after each addition. Mix in vanilla.

Reduce mixer speed to low. Gradually add oat mixture, mixing just until combined.
