Oatmeal Cookies à la Guinea

Preheat oven to 350°F (175°C). Cream together butter, brown sugar, and white sugar until light and fluffy, approximately 2-3 minutes.

Beat in the eggs one at a time, then add the sachet of vanilla sugar and mix until well combined.

In a separate bowl, whisk together the sachet of baking powder, flour, and salt.

Gradually fold the flour mixture into the wet ingredients until just combined, being careful not to overmix.

Stir in the Quaker oats until evenly distributed throughout the dough.

Drop spoonfuls of dough onto ungreased baking sheets, spacing them about 2 inches apart.

Bake in the preheated oven for 12 minutes, or until the edges are golden brown and the centers are set.

Remove from oven and cool on the baking sheet for 2-3 minutes before transferring to a wire rack to cool completely.
