Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking tray.
In a large bowl, mix red velvet cake mix, eggs, water, and oil until smooth. Pour into the tray and bake for 28–32 minutes, or until a toothpick comes out clean. Let cool completely.
Beat butter and cream cheese until smooth. Add powdered sugar and vanilla extract. Beat until fluffy.
Crumble cooled cake into a large bowl. Add about 3/4 cup of frosting. Mix until a dough-like texture forms.
Scoop and roll into 1½-inch balls. Place on a parchment-lined tray. Chill in the fridge for at least 1 hour.
Melt white chocolate or candy melts in a microwave-safe bowl in 20-second intervals, stirring between each.
Dip the tip of each stick in melted chocolate, then insert into a chilled cake ball.
Dip each pop into melted chocolate. Let excess drip off and place on parchment to set.
Melt red candy melts. Spoon into a zip-top bag and snip the corner. Drizzle over the top of each pop for a "bloody" effect.
