Why You’ll Love This Recipe
- This oat milk latte is creamy with a hint of vanilla sweetness. It is not overwhelmingly sweet — but is just the perfect balance.
- This latte is made using homemade vanilla coffee syrup that is made using real vanilla beans. This makes a huge difference in the quality of the latte. There are no artificial or chemical-like flavors that you sometimes have when using store bought coffee syrups.
- This latte tastes just as good as one you’d buy from Starbucks but it is much less expensive to make it at home, and it’s so easy to make.
- This recipe is both vegan and dairy-free so that everyone can enjoy it.
Ingredients & Substitutions
- Vanilla Extract & Vanilla Bean: Vanilla extract and real vanilla beans are used to make the vanilla coffee syrup. Vanilla beans are expensive, but you only need 1 to make a large batch of syrup and it is still less expensive to make your own syrup homemade than buying one store bought.
- Oat Milk: Lattes are made with frothed milk. Not all oat milk froths equally well. Use an oat milk that is labelled as “barista” as this type is meant to be frothed for coffee drinks.
- Espresso: Use high quality, freshly brewed espresso. You could also use very strongly brewed coffee instead. Finally, if needed you could use instant espresso, but make sure it is a high quality one.
- Sugar: Granulated sugar is dissolved into the vanilla syrup so that it also acts as a sweetener for the latte. This recipe would also work with brown sugar, which would give it a richer, slightly caramel flavor.
- Water: Water is used to give the vanilla syrup the proper consistency Use filtered water to avoid any unpleasant tastes from tap water.
Here are the things that you will need to make the vanilla latte:
- A small saucepan to make the vanilla syrup in.
- A fine mesh strainer to strain out any small pieces of vanilla bean from the syrup.
- An electric milk frother to froth the oat milk.
- A glass mason jar to store the leftover vanilla syrup in.
Step By Step Instructions
Step 1: Heat the water, sugar, vanilla extract and split vanilla bean in a saucepan over medium heat. Continue to heat, stirring occasionally until the sugar has fully dissolved.
Step 2: Remove the vanilla syrup from the stove and strain out the vanilla bean.
Step 3: Mix the espresso and vanilla syrup together. Froth the oat milk in an electric frother and pour it on top of the espresso.
- If you don’t have a frother: An electric milk frother is the best, most effective way to froth milk. However, as an alternative, you can use a mini, handheld milk frother. Or, you can warm the milk in the microwave for 30 to 40 seconds and shake it vigorously in a mason jar.
- The vanilla syrup should be liquid. If the syrup is thick and sticky, then the syrup was probably heated for too long or at too high a temperature. To fix this, stir in a ½ tablespoon of water at a time while heating on low, until the syrup has thinned out.
- Store leftover vanilla syrup in the fridge. This recipe will make extra vanilla syrup. Let the syrup fully cool to room temperature before storing. Store the syrup in an airtight glass container in the fridge for up to 1 to 2 weeks. Making a large batch in advance will save time making this latte on busy mornings.
The vanilla bean is the most important ingredient to flavor the vanilla syrup. While the syrup will work without the vanilla bean, it will not taste as authentic or give as rich a vanilla flavor.
The vanilla syrup is a flavoring as well as a sweetener. To make the latte sweeter, you could add an extra ½ to 1 tablespoon of vanilla syrup, honey or maple syrup.
No, but it does give the best results — especially for oat milk. If you plan to make a lot of oat milk lattes, it is definitely a worthwhile investment.
