Start by adding all the ingredients into your large slow cooker. This includes the whole milk, maple syrup, brown sugar, ground ginger, vanilla extract, cinnamon sticks, cloves, nutmeg, and espresso. Stir gently to combine everything well.
Set your slow cooker to low and let it cook for about 3 hours. During this time, you'll want to keep an eye on it to make sure it doesn't boil over. The aroma will start to fill your kitchen, making it hard to resist!
After 3 hours, check the latte to see if it's heated through. If it is, turn the slow cooker to the warm setting and let it cook for another 2 hours. This will allow the flavors to meld beautifully.
Before serving, give the mixture a good stir. Taste it and adjust the sweetness if necessary, adding more maple syrup or brown sugar if you like it sweeter.
Optional: For a playful touch, dip the rims of your cups in caramel sauce followed by the graham cracker crumbs to create a fun garnish.
Pour the hot latte into the prepared cups, top with whipped cream, and drizzle with more caramel sauce if desired. You could even crumble some gingerbread cookies on top for extra indulgence!
The Crockpot Gingerbread Latte is best enjoyed warm, so gather your loved ones and serve it up while it's hot. Everyone will love the festive flavors!
