1. Set oven to 350 degrees (set oven rack to second-lowest position). 2. Prepare an ungreased cookie/baking sheet. 3. In a medium bowl beat softened butter with vanilla using an electric mixer until fluffy (about 4 minutes). 4. Add in confectioners sugar, cornstarch and flour; beat on low speed for about 1 minute, then on high speed for 3-4 minutes more. 5. Add in the mini chocolate chips; mix to combine. 6. Drop by spoonfuls about 2-inches apart on the baking sheet. 7. Bake for about 10-12 minutes (watch that the edges don't brown too much). 8. Cool completely on wire racks then lightly dust with confectioners sugar if desired. ---------------------------------------------------------------------------
