Preheat your oven to 350°F (175°C). Line your cupcake pan with cupcake liners.
In a large mixing bowl, whisk together the Devils Food Cake mix and instant chocolate pudding mix until well combined.
Add the sour cream, vegetable oil, lightly beaten eggs, warm water, and vanilla to the dry ingredients. Using an electric mixer, beat on medium speed for about 2 minutes, until the batter is smooth and well combined.
Spoon the batter into the prepared cupcake liners, filling them about two-thirds full.
Place the cupcake pan in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Remove from the oven and let cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
In a large mixing bowl, beat the room temperature unsalted butter with an electric mixer until creamy. Gradually add in the confectioners sugar, mixing on low speed to avoid a sugar cloud. Once combined, add the clear vanilla extract, fine sea salt, and Southern Comfort. Beat on medium speed until the frosting is light and fluffy.
Gently fold the cooled melted chocolate chips into the frosting until fully incorporated.
Using a spatula or piping bag, generously frost each cooled cupcake with the Southern Comfort frosting.
For an extra touch, drizzle some Southern Comfort Caramel Corn on top of each cupcake for added texture and flavor.
