Add the oat milk and extra virgin olive oil to the milk frother. Adjust the temperature to 140-145 degrees F and start the heating cycle.
Meanwhile, place an espresso pod into your machine. Generate one shot of espresso, dispensing into your mug of choice or transferring the espresso shot into the mug after it brews.
When the oat milk is finished steaming and frothing, gently pour into the mug. Serve hot and enjoy.
Notes
If using something other than a pod-style espresso machine, measure approximately 7 grams of ground coffee (about 2 teaspoons). The oat milk can be heated without a milk frother using a small saucepan and a whisk or hand-held milk frother. Use low heat and monitor closely to avoid scalding.
