Ingredients
- 1 box vanilla cake mix
- 1/2 cup all-purpose flour
- 1/2 cup granulated sugar
- 3 large eggs
- 1/2 teaspoon salt
- 1 cup milk
- 2 tablespoons vegetable oil
- 1 cup sour cream
- 1 teaspoon vanilla extract
- 7 ounces marshmallow creme
- 3/4 cup unsalted butter (softened)
- 1 cup powdered sugar
- 1/4 teaspoon salt
- 1/2 teaspoon vanilla extract
- 2 tablespoons heavy cream
- White chocolate candy melts (melted)
- Pink food coloring
Instructions
- Step 1: Preheat your oven to 350°F and line two 9×13-inch baking sheets with parchment paper.
- Step 2: In a large mixing bowl, combine the vanilla cake mix, all-purpose flour, granulated sugar, salt, eggs, milk, vegetable oil, sour cream, and vanilla extract. Mix until smooth and well blended.
- Step 3: Divide the batter evenly between the prepared baking sheets, spreading it into thin, even layers. If using a half-sheet pan, pour all the batter onto it evenly.
- Step 4: Bake for 15-20 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and let cool completely on a wire rack.
- Step 5: Once cooled, use a heart-shaped cookie cutter to cut out mini heart cakes from both sheets.
- Step 6: To make the frosting filling, beat the softened butter in a bowl until creamy. Add marshmallow creme, powdered sugar, salt, vanilla extract, and heavy cream. Mix until light and fluffy.
- Step 7: Spread frosting on one heart-shaped cake and sandwich another cake on top. Repeat with remaining hearts.
- Step 8: Melt the white chocolate candy melts according to package instructions. Reserve a couple tablespoons of plain melted white chocolate in a separate bowl. Stir pink food coloring into the larger portion until smooth and light pink.
- Step 9: Dip each heart cake into the pink melted chocolate, coating completely. Place on a wire rack with a baking sheet underneath to catch drips and allow to dry.
- Step 10: Use the reserved white chocolate to pipe or drizzle decorative lines or patterns over the coated heart cakes.
Tips & Variations
- For a richer cake, replace the milk with buttermilk and add a teaspoon of lemon juice to enhance the vanilla flavor.
- Use colored candy melts or add food coloring to the frosting for a fun twist on the classic look.
- Ensure cakes are completely cool before cutting hearts to prevent tearing.
- If you don’t have a heart-shaped cookie cutter, use a sharp knife to carefully cut out heart shapes freehand.
Storage
Store the finished heart cakes in an airtight container in the refrigerator for up to 5 days. Allow them to come to room temperature before serving for the best texture. You can also freeze the cakes wrapped tightly; thaw overnight in the fridge before enjoying. Avoid heating as it may cause the chocolate coating to melt.

FAQs
Can I make the cake batter from scratch instead of using mix?
Yes, you can use your favorite homemade vanilla cake batter recipe. Just be sure it yields a similar consistency so the cakes bake thin and evenly for cutting.
What if I don’t have marshmallow creme for the filling?
You can substitute with homemade marshmallow fluff or a simple frosting made from cream cheese and powdered sugar for a different but delicious filling.

- 1 box vanilla cake mix
- 1/2 cup all-purpose flour
- 1/2 cup granulated sugar
- 3 large eggs
- 1/2 teaspoon salt
- 1 cup milk
- 2 tablespoons vegetable oil
- 1 cup sour cream

Frosting Ingredients
- 1 cup powdered sugar
- 3/4 cup unsalted butter (softened)
- 7 ounces marshmallow creme
- 1/4 teaspoon salt
- 1/2 teaspoon vanilla extract
- 2 tablespoons heavy cream
Decoration Ingredients
- White Chocolate Candy Melts (enough to coat the cakes, approximately 8-10 ounces)
- Pink food coloring
Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Line two 9×13 inch baking sheets with parchment paper for easy cake removal.
- Mix the Batter: In a large mixing bowl, combine the vanilla cake mix, all-purpose flour, granulated sugar, salt, eggs, milk, vegetable oil, sour cream, and vanilla extract. Mix thoroughly until the batter is smooth and well combined with no lumps.
- Bake the Cakes: Divide the batter evenly between the two prepared baking sheets. Spread it out into a thin, even layer. Bake in the preheated oven for 15-20 minutes or until a toothpick inserted in the center comes out clean. Remove from the oven and allow to cool completely.
- Cut Heart Shapes: Once cooled, use a heart-shaped cookie cutter to cut out mini heart cakes from the baked sheets. Set the hearts aside.
- Prepare the Frosting: In a mixing bowl, beat the softened unsalted butter until creamy. Add the marshmallow creme, powdered sugar, salt, vanilla extract, and heavy cream. Mix until the frosting is light, fluffy, and smooth.
- Assemble Cake Sandwiches: Take one heart-shaped cake and spread a generous layer of the marshmallow frosting on top. Place a second heart-shaped cake on top to form a sandwich. Repeat with all the heart shapes.
- Melt and Color Chocolate: Melt the white chocolate candy melts according to package instructions. Pour a couple tablespoons of the plain melted white chocolate into a separate piping bag or bowl. Add pink food coloring to the remaining melted white chocolate and stir well to achieve a smooth light pink shade.
- Coat the Cakes: Dip each heart cake sandwich into the pink melted chocolate, making sure it is fully coated. Place the coated cakes onto a wire rack set over a baking sheet to catch drips, and allow the chocolate to set and harden.
- Decorate the Cakes: Use the reserved plain white melted chocolate to pipe or drizzle decorative accents over the pink-coated cakes. Let the decoration set before serving.
Notes
- For best results, ensure the cakes are completely cooled before cutting and assembling to prevent frosting from melting.
- If you don’t have a heart-shaped cookie cutter, you can use any other shape or simply cut small squares.
- Store assembled and coated cakes in an airtight container at room temperature or refrigerated for longer shelf life.
- Use high-quality white chocolate candy melts to achieve a smooth, shiny coating.
- Adjust the amount of pink food coloring as needed to get your desired shade.
