Cube the plant butter and add it to a pan over medium-low heat. Stir every 10 seconds so it doesn’t burn. The butter will foam, then slowly darken and smell nutty. Remove from heat and let cool for about 10 minutes.
In a large bowl, combine the brown sugar, granulated sugar, aquafaba, and vanilla extract until smooth.
In a separate bowl, sift together the all-purpose flour and baking soda.
Once the butter has cooled slightly but is still warm, mix it into the sugar mixture until fully combined. Add the dry ingredients and gently fold together. Do not overmix.
Fold in the chocolate chips until evenly distributed.
Roll the dough into evenly sized balls and place on a plate or baking sheet. Cover with plastic wrap and refrigerate for at least 1 hour.
Preheat oven to 350°F. Place dough balls on a lined baking sheet, spacing them at least 2 inches apart. Bake for 12 minutes.
Let cookies cool on the pan for a few minutes before transferring to a rack. They will continue to set as they cool.
