Cream butter, sugars, almond extract and egg together thoroughly (2-3 minutes). Stir in flour and oats. Mix well.
Spread evenly in greased 8" (2 L) square pan. Bake for 22-25 minutes, or until slightly golden.
Meanwhile, melt chocolate chips with butter in the microwave at 30 second increments until smooth, stirring after each 30 seconds. Spread over base. Sprinkle evenly with almonds. Cool until chocolate sets before cutting into bars.
Notes
*This recipe doubles well for a 9x13" pan and also freezes well in an airtight container. Serve at room temperature.
