Fill a shaker with ice and pour tequila, Cointreau, lime juice, coconut milk (or coconut cream) and simple syrup (if using) into the shaker. Shake to combine until the sides of the shaker are fully frosted.
Serve & Garnish:
Fill a glass with ice and strain the cocktail into the glass.
Add a lime twist for a fancy finishing touch. Sip and enjoy!
Notes
Make it creamier by using coconut cream instead of milk.
FAQ: can I skip the Cointreau or triple sec? Yes. While not as rich in citrus flavor, it will be ok. Increase your tequila to 2oz.
