Prep. Begin by preheating the oven to 350°F (177°C). Line two cookie sheets with parchment paper or lightly coat them with cooking spray to prevent sticking.
Wet Ingredients. In a large mixing bowl, use an electric mixer to cream together the softened butter, granulated sugar, brown sugar, and egg on medium speed until the mixture is light and fluffy, approximately 3 to 5 minutes. Add the vanilla and blend until combined, scraping down the sides of the bowl if necessary.
Dry Ingredients. In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined to avoid overmixing.
Add the Chocolate Chips and Heath Bits. Manually fold the semi-sweet chocolate chips and Heath Bits O'Brickle into the batter, making sure they are evenly distributed throughout.
Shape. Scoop the cookie dough onto the prepared cookie sheets using a tablespoon. Prepare 15 cookies per sheet. Space each scoop approximately 2 inches apart to allow for spreading during the baking process.
Bake. Bake in the preheated oven for 10 to 12 minutes or until the edges of the cookies are golden brown. The precise time may vary depending on the oven, so monitor the cookies towards the end of the baking time.
Cool. Once baked, remove the cookies from the oven and allow them to cool on the cookie sheets for a few minutes before transferring them to wire racks to cool completely.
