There is something deeply grounding about baking a cake for someone you love. It isn’t about achieving bakery perfection or complex techniques; it is about the time spent melting chocolate and whipping butter in a quiet kitchen. This Valentines Cake captures that simple, honest sentiment with rustic charm and deep flavor.
You don’t need a specialty pan to make this heart-shaped treat. By using a square and a round cake layer, we create a beautiful shape that is covered in a fresh strawberry buttercream. It is a tender, chocolatey celebration of affection that tastes as good as it looks.
A Perfect Treat for Any Occasion
This recipe relies on a clever geometric trick rather than a clutter of specialty pans. By combining a square cake and a halved round cake, you get a perfect heart shape every time. It is a fun, hands-on project that feels like a farmhouse craft rather than a stress test.
The flavor profile is a timeless duet of deep chocolate and bright, fresh berries. The buttermilk keeps the crumb tender and moist, while the strawberry buttercream—flecked with real fruit—adds a burst of natural sweetness that balances the rich cocoa.

- 1 cup unsalted butter, softened
- 2 cups granulated sugar
- 3 large eggs, separated
- 1 tsp vanilla extract
- 2 cups all-purpose flour
- 1/4 cup unsweetened cocoa powder
- 1 tsp baking soda
- 1/2 tsp salt

- 1 tsp vanilla extract
- 1/2 cup finely chopped fresh strawberries
- Pinch of salt
Instructions
- Whisk bittersweet chocolate chips and boiling water in a heatproof bowl until smooth and glossy; let cool to room temperature.
- In a mixer, cream softened butter and sugar until light and fluffy, then beat in egg yolks, vanilla, and the cooled chocolate mixture.
- In a separate bowl, whisk flour, cocoa, baking soda, and salt; add to the butter mixture alternately with buttermilk, starting and ending with the flour.
- Beat egg whites in a clean bowl until soft peaks form, gently fold them into the chocolate batter, and pour into prepared square and round pans.
- Bake at 350°F for 25 minutes; while cooling, beat frosting butter, powdered sugar, vanilla, salt, and strawberries until fluffy.
- Place the square cake as a diamond, cut the round cake in half, and attach the semi-circles to the top sides of the square to form a heart before frosting the entire cake.
Notes
To ensure the best structure for assembly, allow the cakes to cool completely before cutting or frosting. If your frosting seems too soft due to the moisture in the fresh strawberries, simply chill it in the refrigerator for 15 to 20 minutes to firm it up before spreading over the cake layers.

Farmhouse Pantry Essentials

Bittersweet Chocolate & Cocoa: We use both melted chocolate and cocoa powder here. The melted chocolate provides a fudgy density, while the cocoa brings that classic baked flavor.
Buttermilk: This is the secret to a tender crumb. The acidity breaks down gluten and interacts with the baking soda for a lovely lift.
Fresh Strawberries: For the frosting, we use finely chopped fresh berries. They provide natural color and a flavor that artificial extracts just can’t match.
Eggs, Separated: Separating the eggs allows us to whip the whites into soft peaks. Gently folding them in creates a batter that is light yet rich.
How to Make It
Step 1: Melt the Chocolate
Start by placing your bittersweet chocolate chips in a heatproof bowl. Pour the boiling water over them and whisk until the mixture is smooth and glossy. Let this cool to room temperature so it doesn’t melt your butter later.
Step 2: Create the Batter
In your mixer, cream the softened butter until it is smooth, then gradually add the sugar until the mixture is light and fluffy. Beat in the egg yolks one at a time, followed by the vanilla and your cooled chocolate mixture.
Step 3: Combine Dry and Wet
Whisk your flour, cocoa, baking soda, and salt in a separate bowl. Add this flour mixture to the butter mixture alternately with the buttermilk. Start and end with the flour, mixing on low speed until just blended.
Step 4: Fold in the Whites
In a clean bowl, beat the egg whites until soft peaks form. Gently fold these into your chocolate batter. This step adds air and lightness to the cake, so take your time and use a light hand. Pour the batter into your prepared square and round pans and bake at 350°F for about 25 minutes.
Step 5: Make the Strawberry Frosting
While the cakes cool, beat the butter for the frosting until creamy. Gradually add the powdered sugar, vanilla, salt, and chopped strawberries. Whip it until fluffy. You can add a drop of pink gel if you want a deeper color.
Step 6: Assemble the Heart
Place the square cake on your platter in a diamond position. Cut the round cake in half to make two semi-circles. Place the flat side of each semi-circle against the top two sides of the square. Frost the entire cake to join the pieces into a seamless heart.
Christine’s Seasonal Secrets

Temperature Matters: Make sure your melted chocolate has cooled to room temperature before adding it to the butter mixture. If it is too hot, it will melt the butter and change the texture of your batter.
The Fold: When folding in egg whites, use a spatula and a sweeping motion. You want to incorporate them without deflating the air you just whipped in. This technique is similar to the one used in our chocolate fudge cake, ensuring a texture that isn’t too dense.
Ripeness Checks: Use strawberries that are red all the way through for the best flavor in your frosting. If they are tart, you might need a touch more powdered sugar.
Seasonal Swaps and Twists
Berry Swap: If strawberries aren’t in season, raspberries make a wonderful alternative. The tartness of raspberries pairs beautifully with the bittersweet chocolate.
White Chocolate: For a different profile, you could swap the chocolate batter for a vanilla base, similar to our raspberry white chocolate cake.
Inspiration: If you enjoy exploring different regional takes on holiday baking, you might find this Valentine’s Day cake interesting for its own unique charm.
Rustic Presentation

Place your heart cake on a large wooden board or a simple white platter to let the pink frosting pop. I love to garnish the edges with fresh strawberry slices or a dusting of sanding sugar for a bit of sparkle.
Serve this with a hot cup of coffee or a glass of cold milk. The richness of the chocolate needs nothing more than good company. If you are looking for more fun shapes, our heart cake guide offers more tips on creative presentations.

Baking this Valentines Cake is a reminder that the best gifts are made by hand. The combination of rich chocolate and fresh strawberry cream is a celebration of simple, honest flavors.
