Preheat oven and prepare the cake according to box instructions using eggs, oil, and water. Bake and let cool completely.
Crumble the cooled cake into a large bowl using clean hands or a fork.
Add 3/4 cup frosting and mix until a dough-like consistency forms.
Roll into 24 small balls (about 1.5 inches wide) and place on a parchment-lined tray.
Melt orange candy melts in a microwave-safe bowl in 20-second intervals, stirring between each.
Dip the tip of each cake pop stick in melted candy, then insert halfway into each cake ball.
Chill the tray in the refrigerator for 30 minutes until firm.
Once chilled, reheat orange candy melts if needed and fully dip each cake pop to coat.
Let excess drip off and insert upright into a Styrofoam block to dry.
Melt white candy melts separately and tint with green gel food coloring to create a pumpkin stem coating.
Using a small brush, paint green lines from top to sides for stem effect.
Optionally, dust with edible glow powder while coating is still tacky for a glowing finish.
Use a mini icing pen or edible marker to draw faces once the coating is dry.
Add edible glitter or candy accents for extra sparkle.
Let decorated pops dry on wax paper or stand in a drying block for 20–30 minutes before serving or storing.
