Ingredients

  • ¾ cup oat milk
  • ½ cup strongly brewed coffee
  • 3 tablespoon toasted cinnamon syrup (recipe below)
  • ¼ teaspoon xanthan gum (can substitute with cornstarch, but use a little bit more)
  • 1 cup ice
  • Nondairy whipped cream (can use regular whipped cream if you prefer)

Toasted Cinnamon Syrup

  • 2 cinnamon sticks
  • 1 cup water
  • ½ cup light brown sugar packed
  • ½ cup granulated sugar

Cinnamon Crumble Topping

  • 1 vanilla cookie (like Golden Oreo or Nilla Wafer) crushed
  • teaspoon ground cinnamon

Instructions

  • Add oat milk, coffee, toasted cinnamon syrup, xanthan gum, and ice to blender and process until smooth and frothy.
  • Pour into cup and top with whipped cream and cinnamon crumble topping.

Toasted Cinnamon Syrup

  • Place a dry cast iron skillet (can also use stainless steel or any nonstick skillet) over medium heat and add cinnamon sticks.
  • Allow cinnamon sticks to toast for about 3-5 minutes, turning them occasionally with tongs to ensure even toasting. Let them toast until they're starting to darken and get fragrant.
  • Put water, both kinds of sugar, and cinnamon sticks in a medium-size saucepan and bring mixture to a boil.
  • Once boiling, lower heat and let mixture simmer for about 10 minutes, until syrup has thickened (note that it will continue to thicken as it cools).
  • Remove from heat and strain cinnamon sticks out of syrup into a heat-proof bowl or mason jar. Place bowl or jar in fridge to cool completely before using. Syrup can be stored in an airtight container in the fridge for up to a month.

Cinnamon Crumble Topping

  • In a small bowl, mix together vanilla cookie crumbs and cinnamon.

Notes

  • See body of post for customization ideas.
  • If you prefer not to make your own toasted cinnamon syrup, you can purchase a bottle or regular cinnamon syrup.
