In a medium saucepan with tall sides over medium high heat, melt the butter, sugars, corn syrup, and salt. Stir rapidly for 5 minutes, until it comes to a boil. Remove off heat and whisk in baking soda. Quickly drizzle in heavy cream mixture and whisk over low heat until it all comes together.

For the latte, whisk the milk, espresso, pumpkin puree, cocoa powder, and spices together over low heat. Bring to a slow simmer.Whisk the heavy cream with sugar to form light whipped cream. Serve hot latte topped with fresh whipped cream and a drizzle of pumpkin caramel.
