Bake a cake according to the package instructions. Allow it to cool completely.
When the cake is completely cool, crumble into a large mixing bowl, ensuring no large pieces.
Mix enough frosting into the crumbled cake to form a dough that holds together.
Line a baking sheet with parchment paper and set it aside.
Roll the mixture into 1"/2.5cm balls. You should have around 20 cake balls. For the Valentine's touch, shape some of them into heart shapes.
Place the cake balls and hearts onto the prepared baking sheet and refrigerate for 30 minutes to firm up.
Melt a small amount (1oz/25g) of white chocolate in the microwave. Dip the end of each lollipop stick into the melted chocolate and insert it into the center of each cake pop. Place the cake pops back on the baking sheet and chill in the refrigerator for about 60 minutes.
Melt the remaining white chocolate in a microwave-safe bowl till smooth. Melt in 30-second intervals, stirring to prevent burning.
Divide the melted chocolate into 2 or 3 bowls. Leave one bowl white, and add food coloring to the other bowls to create shades of pink and/or red.
Dip each chilled cake pop into the melted chocolate, ensuring they are fully coated. Allow excess chocolate to drip off into the bowl.
Add sprinkles or heart-shaped candies. Add any sentiments with icing after the cake pops have set.
Place the covered cake pops back onto the baking sheet and leave to set at room temperature or in the refrigerator for 15-30 minutes until the chocolate hardens.
Serve, enjoy, and Happy Valentine's Day!
Notes
You can make the cake balls and refrigerate them for up to 2 days before dipping and decorating.
