Preheat the oven to 180°C and lightly grease 2 baking trays.
In a large bowl, cream the
softened butter and light soft brown sugar together until the mixture is light
and fluffy.
Add the egg and vanilla extract
to the bowl and continue to beat the mixture for 1 minute until well combined.
Gradually add the flour to the
bowl, mixing until the dough comes together and is fully combined.
Roll the dough into balls, about
1-1/2 inches in diameter.
Roll each dough ball in your
chosen toppings (sprinkles, crushed Oreos, or chocolate chips), pressing
lightly to ensure the toppings stick to the dough.
Place the coated dough balls on
the prepared baking trays, ensuring they are spaced about 2 inches apart.
Bake the cookies in the preheated
oven for 10-12 minutes, or until they are golden brown and cooked through.
After baking, let the cookies
cool on the tray for 1 minute before transferring them to a cooling rack.
