Add butter to the bowl of a stand mixer and cream for 2 mintues.

Add the brown sugar and white sugar and beat again until creamy.

Add the vanilla and egg and mix again until combined. Scrape down sides and bottom with a spatula to be sure.

In another small mixing bowl add the flour, baking soda and baking powder and mix with a whisk.

Add the flour mixture to the butter mixture ½ cup at a time until all mixed.

Using a spatula fold the chocolate chips into the mixture (save some to add after they are baked, for looks).

Using a small cookie scoop take two scoops and lay on a baking sheet lined with parchment paper. Dip your fingers in flour and press the cookie dough into a narrow heart shape. The cookie dough is quite sticky so the flour helps. Heart should be about ½" thick.

Repeat, leaving 2" between each cookie. You'll need two cookie sheets for this, to ensure enough space, or do it in two batches.

Place baking sheet in the refrigerator for a minimum of 2 hours - longer is better.

After this time, heat your oven to 375°.

Bake the cookies for 12 minutes.

Remove and allow to cool on the cookie sheet for 10 minutes before transferring to a wire rack to cool completely.

Repeat with the second batch.
