I've always been a fan of Starbuck's version, but with the cost, it tends to turn people away. This recipe cost me about $10 total to make, and it made well over 4 servings. (I halved the recipe. The full recipe could easily serve 8, depending on the size mug you'll use.)
The recipe is very simple. You need strong coffee and milk. I will post the full recipe at the end of this post. Here are some pictures of the process:
This was the very beginning process before the crock pot heated up.
The finished product, 2 hours after combining ingredients. The pumpkin, cinnamon, milk, and coffee blended well together.
It was a very good mixture, and tasted better than Starbucks. Next time I do it, I will probably add a tad bit more coffee and pumpkin, and a little less cinnamon.
Here is the complete recipe - I halved it and it still made quite a bit, but the full recipe might be a good amount for parties and larger crowds:
6 cups of milk
4-6 cups of strongly brewed coffee
1/2 cup of pumpkin puree
1/2 cup of vanilla extract
1/2 cup of sugar
2 teaspoons of cinnamon
3 cinnamon sticks
In your crock pot, combine the milk and coffee.
Whip together the pumpkin, vanilla, sugar and cinnamon and pour into the crockpot.
Mix together well.
Toss in 3-4 cinnamon sticks.
Cover the crockpot, and cook on high for 2 hours.
