First, brew your espresso shot and let it cool, or grab your cold brew coffee.
In a mug or glass, add the melted cookie butter.
Pour in your chosen milk, brown sugar (or preferred sweetener), and vanilla extract.
Stir everything together until the cookie butter is fully blended and smooth. A small frother or whisk works wonderfully here!
Fill a tall glass generously with ice cubes.
Pour the cookie butter milk mixture over the ice.
Finally, gently add your cooled espresso or cold brew on top.
Give it a final stir and add any optional toppings like a dollop of light whipped cream, a dash of cinnamon, or a crushed cookie for extra flair! Enjoy this refreshing treat.
