1-First, whisk together the 6 cups of whole milk and 6 cups of strongly brewed coffee directly in the slow cooker. In a separate bowl, mix the 1/2 cup pumpkin puree, 1/4 cup real vanilla extract, 1/2 cup sugar, and 2 teaspoons cinnamon until well combined, then add this mixture to the slow cooker. Whisk all the ingredients together thoroughly and toss in the 3 to 4 cinnamon sticks for added flavor.

2-Next, cover the slow cooker and cook on high for 2 hours to let the flavors meld perfectly. After the initial cooking time, switch to a low or warm setting to keep it ready for serving. It takes just 5 minutes of prep and 2 hours of cooking, fitting easily into your routine.

3-Finally, serve the latte warm, and feel free to adjust based on taste. This approach not only simplifies the process but also allows for easy adaptations like using non-dairy milk.
