Step-by-Step Instructions For This Romantic Valentine Cake

Follow these directions to create your perfect heart-shaped chocolate cake.

Step 1: Prep the Pans

Preheat oven to 325°F (165°C). Spray one 8-inch round pan and one 8-inch square pan with baking spray. Wipe lightly with a paper towel, spray again, and line bottoms with parchment paper.

Step 2: Mix Butter, Water & Cocoa

In a large microwave-safe bowl, combine butter, water, and cocoa. Microwave on high for 3 minutes, or until butter is mostly melted. Whisk until smooth and lump-free.

Step 3: Add Vanilla and Sugar

Whisk in vanilla extract and sugar until fully combined.

Step 4: Add Dry Ingredients

Add flour and salt, whisking until smooth after each addition.

Step 5: Add Eggs

Whisk in eggs, one at a time, until the batter is completely smooth.

Step 6: Add Baking Soda and Buttermilk

Sprinkle baking soda over the batter, then pour in buttermilk. Stir until glossy and consistent.

Step 7: Divide and Bake

Tap the bowl gently to release air bubbles. Divide the batter evenly between pans (the square will hold slightly more). Bake 35–40 minutes, until a toothpick inserted in the center comes out clean. Cool in pans for 10 minutes, then remove and cool completely on a wire rack.

Step 8: Make the Icing

In a large microwave-safe bowl, melt chocolate pieces on power level 5 (50%) for 1 minute. Stir, then heat in 20-second increments until melted. Whisk in cocoa powder, then soft butter until smooth. Add sour cream, half & half, and vanilla — whisk until silky. Gradually whisk in powdered sugar, one cup at a time, until smooth, shiny, and spreadable.

Step 9: Shape the Heart

Place the square cake diagonally on a serving platter. Cut the round cake in half and attach each half to the upper sides of the square, forming a heart.

Step 10: Frost the Cake

Spread the chocolate icing generously over top and sides, working carefully around the curves. Decorate immediately with pink and red nonpareils. Let rest for 30 minutes to set.

Pro Tips for Success

• Don’t overbake — it’s best when moist and tender.
• Always cool completely before icing.
• If the icing thickens too much, whisk in a teaspoon of half & half.
• For clean slices, dip your knife in warm water and wipe between cuts.
• Sprinkle decorations while frosting is soft for a pretty finish.

Serving Ideas

Serve this romantic valentine cake with a Strawberry Matcha Latte or fresh raspberries for a café-style dessert moment.
