Instructions

Step 1
Preheat oven to 350°F (175°C). Grease two 9-inch (23cm) heart-shaped cake pans and line the bottoms with parchment paper.
Step 2
In a medium bowl, whisk together cake flour, cocoa powder, baking powder, baking soda, and sea salt. Set aside.
Step 3
In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium speed for 1 minute until creamy. Gradually add sugar and continue beating for 2–3 minutes until light and fluffy.
Step 4
Add eggs one at a time, beating on low speed after each addition just until blended. Scrape down the bowl sides as needed.
Step 5
Stir in red gel food coloring, vanilla extract, and white vinegar until the batter is evenly colored.
Step 6
With the mixer on low, add one-third of the dry ingredients, then half of the buttermilk, mixing just until incorporated. Repeat with another third of dry ingredients, remaining buttermilk, and finish with the last third of dry ingredients. Do not overmix.
Step 7
In a small cup, combine 1 teaspoon distilled white vinegar with baking soda, then gently fold into the batter. The mixture will foam slightly to create a light crumb.
Step 8
Divide the batter evenly between the prepared pans, smoothing the tops with an offset spatula. Bake on the center rack for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
Step 9
Let cakes cool in pans for 10 minutes. Run a thin knife around the edges, then invert onto wire racks and remove parchment. Cool completely before frosting.
Step 10
While the cakes cool, make the cream cheese frosting: In a clean mixer bowl, beat cream cheese and butter on medium speed for 2 minutes until smooth. Gradually add powdered sugar and a pinch of salt, then vanilla extract, beating on low until combined and fluffy.
Step 11
Level cake domes with a serrated knife if needed. Place one heart cake layer on a cake board. Pipe or spread about ¾ cup of frosting over the top. Top with the second layer and refrigerate for 15 minutes to set the crumb coat.
Step 12
Apply a thin crumb coat of frosting over the entire cake. Chill for 10 minutes, then add a final smooth layer of frosting using an offset spatula.
Step 13
Prepare the Betty Boop silhouette: Place the stencil under parchment. Pipe or brush melted dark chocolate over the outline. Allow the chocolate to fully set at room temperature or in the refrigerator for 10 minutes.
Step 14
Carefully peel the chocolate silhouette from the parchment and lift it onto the center of the cake, pressing gently to adhere to the frosting.
Step 15
Decorate the cake edges with additional frosting rosettes, edible glitter, or red sugar pearls. Chill for 30 minutes before serving. Slice with a warm, clean knife for neat hearts.

Zusatztipps für die Zubereitung

Using room-temperature ingredients is vital for achieving a smooth batter and a consistent rise. Always use gel-based food coloring for the cake layers to ensure a vibrant red color without thinning out the batter.

Varianten und Anpassungen

For a different visual impact, you can swap the dark chocolate silhouette for white chocolate dyed black with oil-based coloring. This provides a sharper, brighter contrast against the cream cheese frosting.

Serviervorschläge

To serve, use a warm, dry serrated knife to cut clean, sharp slices that maintain the heart shape. For an extra touch of glamour, decorate the base of the cake with edible glitter or sugar pearls to complement the Betty Boop theme.

Recipe FAQs

What makes the red color so vibrant?

Gel-based food coloring delivers intense red hue without thinning the batter or altering the final texture. Liquid coloring can add too much moisture, affecting the crumb structure and rise.

Can I make this without heart-shaped pans?

Yes, bake in two 9-inch round pans instead. Once cooled, use a heart-shaped template to cut layers, or simply create the silhouette on round layers for a unique presentation.

Why is vinegar added to the batter?

White vinegar activates the baking soda, creating extra lift for a lighter, tender crumb. The tanginess also enhances the cream cheese frosting's flavor profile.

How do I prevent the chocolate silhouette from breaking?

Ensure chocolate is completely set before peeling from parchment. Work in a cool room and handle edges gently. Refrigerate the silhouette for 10 minutes if your kitchen is warm.

Can I make the layers ahead of time?

Bake and cool layers completely, wrap tightly in plastic, and freeze for up to 2 weeks. Thaw overnight in the refrigerator before frosting and decorating.

What's the best way to slice neat pieces?

Use a warm, clean knife dipped in hot water and wiped dry between cuts. The heat helps glide through frosting cleanly, and chilled slices hold their shape best.

01 6 ounces dark chocolate or candy melts, melted

Directions

Step 01

Prepare Pans and Preheat Oven: Preheat oven to 350°F. Grease two 9-inch heart-shaped cake pans and line the bottoms with parchment paper.

Step 02

Combine Dry Ingredients: In a medium bowl, whisk together cake flour, cocoa powder, baking powder, baking soda, and sea salt. Set aside.

Step 03

Cream Butter and Sugar: In the bowl of a stand mixer fitted with the paddle attachment, beat butter on medium speed for 1 minute until creamy. Gradually add sugar and continue beating for 2–3 minutes until light and fluffy.

Step 04

Incorporate Eggs: Add eggs one at a time, beating on low speed after each addition just until blended. Scrape down the bowl sides as needed.

Step 05

Add Color and Flavorings: Stir in red gel food coloring, vanilla extract, and white vinegar until the batter is evenly colored.

Step 06

Alternate Dry and Wet Ingredients: With the mixer on low, add one-third of the dry ingredients, then half of the buttermilk, mixing just until incorporated. Repeat with another third of dry ingredients, remaining buttermilk, and finish with the last third of dry ingredients. Do not overmix.

Step 07

Activate Baking Soda: In a small cup, combine 1 teaspoon vinegar with baking soda, then gently fold into the batter. The mixture will foam slightly—this creates a light crumb.

Step 08

Fill and Bake Cakes: Divide the batter evenly between the prepared pans, smoothing the tops with an offset spatula. Bake on the center rack for 25–30 minutes, or until a toothpick inserted in the center comes out clean.

Step 09

Cool Cakes: Let cakes cool in pans for 10 minutes. Run a thin knife around the edges, then invert onto wire racks and remove parchment. Cool completely before frosting.

Step 10

Prepare Cream Cheese Frosting: In a clean mixer bowl, beat cream cheese and butter on medium speed for 2 minutes until smooth. Gradually add powdered sugar and a pinch of salt, then vanilla extract, beating on low until combined and fluffy. Transfer to a piping bag or keep covered in the refrigerator until ready.

Step 11

Assemble and Crumb Coat: If desired, level cake domes with a serrated knife. Place one heart cake layer on a cake board or plate. Pipe or spread an even layer of frosting over the top. Top with the second cake layer, press gently, and refrigerate for 15 minutes to set the crumb coat.

Step 12

Apply Final Frosting Layer: Apply a thin crumb coat of frosting over the entire cake. Chill for another 10 minutes, then add a final smooth layer of frosting. Use an offset spatula to create swirls or leave smooth as desired.

Step 13

Create Betty Boop Silhouette: Place the printed stencil under a sheet of parchment. Pipe or brush melted dark chocolate over the outline on the parchment. Allow the chocolate silhouette to fully set at room temperature or in the refrigerator for 10 minutes.

Step 14

Apply Chocolate Silhouette: Carefully peel the chocolate silhouette from the parchment and lift it onto the center of the cake. Press gently so it adheres to the frosting.

Step 15

Decorate and Chill: Decorate the cake edges with additional frosting rosettes, edible glitter, or red sugar pearls. Chill the cake for 30 minutes before serving to let the frosting set. Slice with a warm, clean knife for neat hearts.
