Ingredients
- White fondant
- Gel icing colors (pink, orange, yellow, blue, green, violet)
- Small heart cookie cutter
- Food writer pen
- 1 cup (240ml) warm milk
- 2/3 cup conversation hearts (white, pink, purple recommended)
- 1 1/4 cups (163g) all-purpose flour
- 2 tsp baking powder
- ¼ tsp salt
- 6 tbsp (84g) unsalted butter, room temperature
- 3/4 cups (155g) sugar
- 1/4 cup (58g) sour cream
- 1 tsp vanilla extract
- 1/2 cup plus 2 tbsp (150ml) conversation heart milk
- 3 large egg whites, room temperature
- 1 1/4 cups (280g) unsalted butter, room temperature (for buttercream)
- 5 cups (575g) powdered sugar
- 1 1/4 tsp vanilla extract (for buttercream)
- 3-4 tbsp (30-45ml) conversation heart milk (for buttercream)
- Salt, to taste
- 5 ziplock bags
- Clear wrap
- Piping bag
- Ateco 847 piping tip (or similar)
Instructions
- Step 1: Make the fondant hearts 1-2 days ahead by dividing white fondant into six golf ball-sized pieces. Leave one white, then color the others yellow, pink, orange, purple, and green using gel colors. Roll out each color and cut heart shapes with a small cutter. Allow hearts to dry and firm for a day or two, then write conversation heart sayings on them with a food writer pen.
- Step 2: Prepare conversation heart milk by stirring warm milk with conversation hearts in a large jar until fully dissolved, about an hour. This can be made a day ahead and refrigerated.
- Step 3: Preheat oven to 350°F (176°C) and line a cupcake pan with liners. In a medium bowl, whisk together flour, baking powder, and salt and set aside.
- Step 4: Cream the butter and sugar in a large bowl until light and fluffy, 2-3 minutes. Add sour cream and vanilla extract and mix well.
- Step 5: Mix in half of the dry ingredients, then add the conversation heart milk and mix. Add remaining dry ingredients and mix until smooth, scraping the bowl as needed. Avoid overmixing.
- Step 6: In a separate bowl, whip egg whites on high speed until soft peaks form. Gently fold the egg whites into the batter in two additions until fully incorporated.
- Step 7: Fill cupcake liners slightly more than halfway. Bake 15-17 minutes or until a toothpick inserted comes out with a few crumbs. Cool in pan 2-3 minutes then transfer to a wire rack to cool completely.
- Step 8: To make buttercream, beat butter until smooth. Add half the powdered sugar and beat until combined. Mix in vanilla and 2 tbsp conversation heart milk, then add remaining powdered sugar and continue beating. Add remaining milk and a pinch of salt, mixing until smooth.
- Step 9: Divide buttercream into five bowls. Color each with gel colors matching the fondant hearts: yellow, pink, orange, purple, and green.
- Step 10: Fill ziplock bags with each color of frosting. Lay clear wrap on a surface and pipe thick rows of each color side-by-side on the wrap. Fold the wrap lengthwise to form a long log, twist ends closed, and trim one end so frosting is exposed.
- Step 11: Insert the frosting log into a piping bag fitted with the Ateco 847 tip. Pipe colorful swirls onto cooled cupcakes.
- Step 12: Top each cupcake with a fondant conversation heart or actual conversation heart candy for a festive finish.
Tips & Variations
- For best fondant coloring, knead gel color thoroughly for even shades matching classic conversation hearts.
- If you don’t have a food writer pen, edible markers or a fine brush with food coloring can work to write messages.
- Use fresh, room temperature egg whites for optimal whipping volume.
- Experiment with different piping tips for unique frosting textures.
- Conversation heart milk can be substituted with vanilla milk if unavailable, but it adds the signature flavor.
Storage
Store cupcakes in an airtight container at room temperature for up to 2 days or refrigerate up to 4 days. Bring refrigerated cupcakes to room temperature before serving. Keep fondant hearts in an airtight container at room temperature; avoid humidity to prevent stickiness. Leftover buttercream can be refrigerated for up to a week and re-whipped before use.

Instructions
- Make the Fondant Hearts: Break off six pieces of fondant about the size of a golf ball. Leave one white and color the others pink, orange, yellow, purple, and green by mixing green and blue gel colors. Roll out each color separately and cut out small hearts using a heart-shaped cookie cutter. Set aside to dry and firm up for 1-2 days. Once firm, use a food writer pen to write classic conversation heart sayings on each heart.
- Prepare Conversation Heart Milk: Place warm milk and conversation hearts in a large jar or measuring cup. Stir occasionally while the candy dissolves completely which takes about an hour. This can be made a day in advance and refrigerated.
- Preheat and Prepare for Baking: Preheat oven to 350°F (176°C). Line a cupcake pan with liners.
- Mix Dry Ingredients: Whisk together the flour, baking powder, and salt in a medium bowl and set aside.
- Cream Butter and Sugar: In a large bowl, beat the butter and sugar together for 2-3 minutes until light and fluffy, ensuring thorough creaming.
- Add Sour Cream and Vanilla: Mix in sour cream and vanilla until combined.
- Incorporate Dry Ingredients and Conversation Heart Milk: Add half of the dry ingredients and mix gently. Slowly pour in the conversation heart milk and continue mixing. Add remaining dry ingredients and mix until smooth, scraping down the bowl sides. Avoid over mixing.
- Whip Egg Whites: In a separate large bowl, beat egg whites on high speed until soft peaks form.
- Fold Egg Whites Into Batter: Gently fold egg whites into the cake batter in two additions until no streaks remain.
- Fill and Bake: Spoon batter into cupcake liners filling slightly more than halfway. Bake for 15-17 minutes or until a toothpick inserted comes out with a few moist crumbs.
- Cool Cupcakes: Let cupcakes cool in the pan 2-3 minutes before transferring to a wire rack to cool completely.
- Make Buttercream Frosting: Beat butter in a large bowl until smooth. Add half of the powdered sugar and beat until creamy. Mix in vanilla and 2 tbsp conversation heart milk. Add remaining powdered sugar and continue beating until smooth. Add remaining milk gradually to achieve desired consistency, adding a pinch of salt to balance sweetness.
- Color the Buttercream: Divide buttercream into 5 bowls and color each one yellow, pink, orange, purple, and green (mixing green and blue for the green shade) to mimic conversation heart colors.
- Prepare Multi-Color Frosting Bag: Spoon each colored buttercream into separate ziplock bags. On a piece of clear wrap, pipe thick stripes of each color side-by-side. Fold the wrap around the colors into a long log, twist ends to seal, then trim one end to expose frosting.
- Pipe Swirled Frosting: Insert the frosting log into a piping bag fitted with Ateco 847 tip or similar. Pipe vibrant swirls on top of each cooled cupcake.
- Decorate: Top each cupcake with either a fondant conversation heart or real conversation heart candy for a festive finish.
Notes
- Fondant hearts can be made 1-2 days ahead to ensure they dry properly and hold their shape.
- Conversation heart milk needs about an hour to dissolve completely and can be prepared a day in advance and refrigerated.
- Do not over mix the batter once the dry ingredients are added—over mixing can make cupcakes dense.
- Be gentle folding whipped egg whites into the batter to retain airiness for light cupcakes.
- Adjust buttercream milk quantity to achieve perfect piping consistency.
- If you don’t have a food writer pen, use a very fine-tipped edible marker as a substitute.
- The multicolor frosting swirl creates a fun and visually appealing design but can be done with single colors if desired.
