Place the cream cheese into the bottom of your mug. Microwave for 30 seconds to soften the cream cheese.
Add the rest of the ingredients except the toppings to the mug and mix until smooth.
Place the cheesecake in the microwave. Cook the cheesecake in the microwave at 50% power in 1-minute increments for a maximum of 2 minutes. If cooking at normal power cook in 30-second increments for a maximum of 1 minute.
Remove the cheesecake from the microwave and chill it in the refrigerator for 1-2 hours. Top with sugar-free sweetened whipped cream and a sprinkle of pumpkin spice for garnish. Enjoy!
