For the syrup: heat all simple syrup ingredients in a saucepan over medium-high heat, stirring occasionally until the sugar dissolves. Bring mixture to a boil and then simmer for 1 minute.
Remove saucepan from heat and allow flavors to sit for 30 seconds before straining everything through a fine mesh strainer. Wait until syrup has cooled before using.
For the latte: combine 2-4 tbsp simple syrup (you can decide how sweet you want your drink to be), coffee, milk, and ice in a glass and stir.
Enjoy!
Notes
*The lavender chai syrup makes more than 1 serving, but the actual drink measurements are just for one. Feel free to make as many as you want!
