Mix the cake base: In a large bowl, combine the cake crumbs and frosting. Mix until the texture feels like cookie dough and holds together easily when pressed.
Shape the cake balls: Roll the mixture into 1-inch balls and place them on a parchment-lined baking sheet. Chill in the refrigerator for 1 hour, or freeze for about 20 minutes, until firm.
Melt the coating: Follow the package instructions for the candy melts or chocolate, stirring until smooth and glossy.
Insert the sticks: Dip the tip of each lollipop stick into the melted coating, then insert it halfway into a cake ball. This helps secure the stick and prevents slipping.
Dip the cake pops: Carefully dip each cake pop into the melted coating, gently tapping to remove excess for a smooth finish.
Decorate right away: While the coating is still wet, add sprinkles, crushed peppermint, or drizzle with a contrasting candy melt for a festive look.
Let them set: Place the cake pops upright in a styrofoam block or foam board and let them sit until completely firm before serving or storing.
