Ingredients:

  • 1.5 Liters strong brewed coffee
  • 950 ml whole milk
  • 240 ml heavy whipping cream
  • 120 grams 100% pumpkin puree
  • 80 ml maple syrup
  • 50 grams dark brown sugar
  • 15 ml vanilla extract
  • 10 grams pumpkin pie spice
  • 2 whole cinnamon sticks

Instructions:

  1. Place the 120 grams of pumpkin puree, 50 grams of dark brown sugar, 80 ml of maple syrup, and 10 grams of pumpkin pie spice into the slow cooker.
  2. Whisk these four ingredients together until a glossy, thick paste forms. This creates a concentrated flavor base that won't separate later.
  3. Slowly pour in the 950 ml of whole milk and 240 ml of heavy whipping cream.
  4. Continue whisking until the mixture is a uniform pale orange with no visible streaks.
  5. Pour in the 1.5 Liters of strong brewed coffee and drop in the 2 whole cinnamon sticks.
  6. Cover the slow cooker and set it to Low for 2 hours.
  7. Stir the mixture gently every 45 minutes until the aromas of nutmeg and coffee fill the room.
  8. After the 2 hours are up, stir in the 15 ml of vanilla extract.
  9. Pour the latte through a fine mesh strainer into a clean pitcher or directly into mugs until the liquid is perfectly translucent and smooth.
