Preheat your oven to 375°F (190°C). Line two baking sheets with parchment paper.

Cream together the butter, granulated sugar, and brown sugar until light and fluffy, about 3-5 minutes with an electric mixer.

Beat in the eggs, one at a time, then stir in the vanilla extract and acorn flavor drops. Adjust the amount of acorn flavor drops according to your preference.

Whisk together the flour, baking soda, and salt in a separate bowl. Gradually add to the wet ingredients, mixing until just combined. If using, fold in the chocolate chips or nuts.

Drop dough onto the prepared baking sheets, spacing them about 2 inches apart. Bake for 8-10 minutes, until the edges are lightly golden.

Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
