Line a baking sheet with parchment paper.

Using a small ice cream scoop, scoop 12 cookies per sheet.

Remove slightly cooled cookies from baking sheet and let cool on a cooling rack.

Once cookies are completely cooled, melt chocolate chips in the microwave. Heat for 30 seconds at a time, stirring each time until melted.
