- 3 cupcakes Cupcakes (any flavor) (baked, cooled and crumbled; can use leftover cake pieces)

Instructions
Melt White Candy Melts for Base Layer
Place 100 g of white candy melts in a microwave‑safe bowl and heat in 10‑15 second intervals, stirring after each burst until fully melted and smooth.
Time: PT5M
Color the Melt for Pastel Pink Hearts
Add a few drops of oil‑based pink rose food coloring to the melted white candy, stirring until the desired pastel shade is reached.
Time: PT2M
Create First Pink Shell Layer
Using a teaspoon, pour about 1.5 tsp of the pink melt into each heart cavity, spreading with the back of a spoon or small spatula to coat the sides evenly.
Time: PT5M
Trim Excess Melt
Run a sharp knife around the outer edge of each heart to remove any excess candy melt, leaving a clean border.
Time: PT2M
Melt White Candy Melts for Polka‑Dot Design
In a clean bowl, melt another 50 g of white candy melts using the same microwave method.
Time: PT3M
Color Melt Black and Paint Dots
Add oil‑based black food coloring to the melted white candy until a deep black is achieved. Dip the small paintbrush into the thick black melt and dab irregular dots onto the interior of two hearts, covering both the base and side walls.
Time: PT5M
Melt White Candy Melts for Rose Design
Melt a third batch of 50 g white candy melts; keep it a bit runnier (use deco‑melts if available).
Time: PT3M
Prepare Colored Melts for Rose Petals and Leaves
Divide the melt into three small bowls and color them with pink rose, raspberry (dark pink), and mint green food colorings respectively.
Time: PT7M
Paint Vintage Rose Design Inside Molds
Using a fine brush, first draw curved pink lines, then fill gaps with darker pink for rose centers, and finish with tiny green leaves. Build up to a 1 cm diameter flower in each heart.
Time: PT7M
Chill Painted Hearts to Set
Place the mold in the refrigerator for about 10 minutes until the painted designs are firm.
Time: PT10M
Temperature: 4°C
Fill Remaining Hearts with White Background
Melt the remaining white candy melts, let them cool slightly, then pour ~1.5 tsp into each of the remaining empty heart cavities, covering the black‑dot and rose designs without smearing them.
Time: PT5M
Second Chill to Harden Shells
Return the mold to the refrigerator for another 10 minutes until all shells are completely solid.
Time: PT10M
Temperature: 4°C
Prepare Cake Crumb Mixture
Crumble the three cupcakes into fine crumbs, add 3 tbsp vanilla buttercream, and mix until the mixture clings together like dough.
Time: PT5M
Fill Hearts with Cake Mixture
Press a small ball (~22 g) of the cake mixture into each heart cavity, leaving a slight gap at the top for a seal.
Time: PT5M
Seal Hearts with a Thin Candy Melt Layer
Melt a small amount of white candy melt, drizzle ~1 tsp over the back of each filled heart, and smooth with an offset spatula to seal the cake inside.
Time: PT5M
Final Chill Before Unmolding
Place the mold back in the refrigerator for 5 minutes to ensure the seal hardens.
Time: PT5M
Temperature: 4°C
Unmold and Trim Edges
Gently pop each heart out of the silicone mold and run a knife around the outer edge to remove any stray candy melt.
Time: PT3M
Add Sprinkles (Optional)
Melt a small amount of white candy melt, fill a piping bag with a tiny opening, pipe a thin line of melt on the edge of each heart, and immediately press the desired sprinkles onto the wet melt.
Time: PT5M
Final Set and Serve
Allow the decorated hearts to set at room temperature for 2‑3 minutes, then arrange on a platter and serve.
Time: PT3M
