Before adding the cake mix, it is important to heat treat the dry cake mix. Add the cake mix to a medium-sized heat-safe bowl. Microwave the cake mix for two to three 30-second intervals, stirring after each interval, until it reaches 165 degrees. Allow the cake mix to cool completely before mixing it into the cream cheese mixture.
Line two large baking sheets with a piece of parchment paper or a silicone mat. Set aside.
In a large mixing bowl, add the room-temperature cream cheese and ground cinnamon. Beat on medium-high speed, using a handheld mixer, for 1-2 minutes or until light and fluffy.
Add the vanilla cake mix and one ounce of Fireball whisky to the bowl of beaten cream cheese. Beat for an additional 1-2 minutes. At this time, you can add more Fireball whisky to reach the desired Fireball flavor (subtle to strong). Beat an additional 1-2 minutes until fully combined.
Cover the bowl with plastic wrap and refrigerate for 2 hours.
Using a 1-inch cookie scoop, scoop out a level scoop and roll it in the palm of your hands to make a smooth ball.
Place the ball onto one of the prepared baking sheets. Repeat until all the balls have been rolled.
Heat the vanilla almond bark according to the package directions (1 minute in a microwave-safe bowl, stir, then heat in 30-second increments), stirring between increments until the almond bark is smooth.
Using a fork, dip a chilled Fireball Whiskey ball into the melted vanilla almond bark. Roll the ball around until all sides are coated. Using the fork to remove the coated ball, tap the fork on the side of the bowl to allow any excess almond bark to drip off.
Place the vanilla almond bark ball onto the second parchment paper-lined baking sheet and sprinkle the top with a pinch of ground cinnamon.
Repeat until all the Fireball whiskey balls have been coated and sprinkled with a pinch of cinnamon.
Set the baking sheet of coated balls into the refrigerator for at least 30 minutes to help the cream cheese and vanilla almond bark to chill and firm up especially if you are planning to leave them out for 2-3 hours.
