01 - Bake chocolate cake in accordance with package instructions, using designated eggs, oil, and water. Rest on a rack until completely cool.
02 - In a microwave-safe bowl, heat caramel candies and heavy cream in 30-second intervals, stirring until smooth and combined. Blend in sea salt; set aside to reach room temperature.
03 - Crumble cooled cake into a large mixing bowl. Add softened cream cheese and unsalted butter; blend with mixer until a uniform, moldable dough is achieved.
04 - Portion about 1 tablespoon of cake mixture. Flatten gently, fill center with 1/2 teaspoon salted caramel, and encase to create a compact ball. Repeat for remaining dough. Place formed pops on a baking sheet and freeze for 15 minutes.
05 - Melt candy melts as directed on packaging. Dip tip of each lollipop stick in melted candy, then insert into each cake ball. Refrigerate for 10 minutes to secure the sticks.
06 - Fully submerge each chilled cake pop in melted candy coating, allowing excess to drain. Stand upright in styrofoam block or cake pop stand.
07 - While coating is still soft, affix candy eyes and sprinkles. Pipe monster mouths and detailed accents with melted white chocolate using a piping bag.
08 - Leave cake pops at room temperature until the coating completely solidifies before serving or packaging.
