What You’ll Need
- Ice cubes – To keep it nice and chilled
- Hazelnut syrup (2 tbsp) – Adds that rich, nutty sweetness
- Vanilla extract (¼ tsp) – Just a little for extra depth
- Cola (1 cup) – Your favorite brand works!
- Half-and-half (¼ cup) – Makes it smooth and creamy
- Whipped cream – Optional, but highly recommended
- Caramel drizzle – For a little extra indulgence

Pro Tips
- Chill your glass first – A cold glass keeps the drink extra refreshing.
- Pour slowly – Adding the half-and-half too fast can cause it to separate. Pour gently for a smooth blend.
- Adjust the sweetness – If you like it less sweet, start with less hazelnut syrup and add more as needed.
- Try different sodas – If you’re not a cola fan, root beer or cream soda are amazing swaps.
- Stir or layer? – Stir for a well-mixed drink or leave it layered for that pretty look before sipping.
