Bake a small batch of oatmeal chocolate chip cookies with rolled oats and semi-sweet chocolate chips, perfect for a quick, chewy treat in under 30 minutes.
Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2-3 minutes.
Add the egg and vanilla extract to the butter mixture and beat until fully combined.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing until just combined.
Fold in the rolled oats and chocolate chips until evenly distributed throughout the dough.
Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them about 2 inches apart. Bake for 10-12 minutes, or until the edges are golden brown but the centers are still soft. Let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
