Step 1: Bake the Cake
- Preheat your oven to 350°F (175°C).
- Prepare your cake mix according to box instructions and pour into a parchment-lined baking sheet for thin, even layers.
- Bake for 20–25 minutes or until a toothpick comes out clean.
- Let it cool completely before cutting.
Step 2: Cut Out the Hearts
- Use your heart-shaped cookie cutter to slice out even pairs from the cooled cake.
- You should get around 10–12 heart sets, depending on cutter size.
Step 3: Fill the Cakes
- Spread a layer of marshmallow creme or whipped frosting on one heart and top with its pair to form a sandwich.
- Press gently so the filling just peeks out.
Step 4: Make the Coating
- Melt white chocolate chips or candy melts in the microwave, stirring every 30 seconds.
- Add a few drops of red or pink food coloring to achieve that signature shade.
Step 5: Coat and Decorate
- Dip or spoon the pink coating over each heart cake until fully covered.
- Place on a cooling rack and let the coating harden.
- Add sprinkles or glitter before it sets if you’re feeling extra festive.
Step 6: Chill and Serve
- Refrigerate for 10–15 minutes to help the coating set fully.
- Serve chilled or room temperature—and enjoy the smiles!
