Cake Batter

Method

Cake Batter

  1. 1

    Prepare and preheat

    Preheat the oven to 350°F (175°C). Grease the heart-shaped 8-inch cake pan thoroughly with butter or nonstick spray and dust lightly with 1 tsp flour, tapping out excess.

  2. 2

    Mix dry ingredients

    In a large bowl, sift together 1.75 cups all-purpose flour, 0.75 cups unsweetened cocoa powder, 1.5 cups granulated sugar, 1 tsp baking powder, 0.5 tsp baking soda, and 0.5 tsp fine salt. Whisk to combine evenly.

  3. 3

    Combine wet ingredients

    In a separate bowl, whisk 2 large eggs until lightly beaten. Add 1 cup whole milk, 0.5 cup vegetable oil, and 2 tsp vanilla extract; whisk until blended.

  4. 4

    Make batter

    Pour the wet mixture into the dry ingredients and stir with a spatula until just combined and no large streaks of flour remain. Do not overmix. Slowly stir in 0.75 cup hot water (or hot coffee for more chocolate depth) until batter is smooth; it will be thin.

  5. 5

    Bake

    Pour the batter into the prepared heart pan, smoothing the top. Bake in the preheated oven for 28–35 minutes or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). Rotate pan halfway through baking for even rise if your oven is uneven.

  6. 6

    Cool

    Remove cake from oven and let cool in the pan for 10–15 minutes. Run a thin knife around the edges, invert onto a wire rack, and remove pan. Let the cake cool completely (at least 1 hour) before frosting to prevent buttercream from melting.

Chocolate Buttercream

  1. 7

    Prepare butter

    Ensure 1.75 cups unsalted butter are at room temperature and soft but not oily. Place butter in the bowl of a stand mixer fitted with the paddle attachment (or use a large bowl and hand mixer). Beat on medium speed for 2–3 minutes until pale and fluffy.

  2. 8

    Add dry components

    Sift together 4 cups powdered sugar and 0.75 cup unsweetened cocoa powder to avoid lumps. With the mixer on low, gradually add the sifted sugar and cocoa to the butter in three additions, scraping the bowl between additions.

  3. 9

    Adjust consistency and flavor

    Once combined, add 0.5 cup heavy cream, 1 tsp vanilla extract, 0.25 tsp fine salt, and 2 tbsp cooled espresso or strong coffee (optional). Increase mixer speed to medium-high and beat 2–3 minutes until light and fluffy. If frosting is too thick, add heavy cream 1 tbsp at a time; if too thin, add a bit more powdered sugar (1/4 cup increments) until spreadable.

  4. 10

    Taste and finish

    Taste and adjust salt or coffee for depth if desired. Transfer buttercream to a bowl and cover with plastic wrap touching the surface if not using immediately to prevent a crust.

Assembly & Decoration

  1. 11

    Level and crumb coat

    If the cake has a domed top, level it with a serrated knife to create a flat surface. Place the heart cake on a cake board or serving plate. Apply a thin layer of chocolate buttercream around the entire cake to trap crumbs (crumb coat). Refrigerate for 20–30 minutes until the crumb coat is firm.

  2. 12

    Final frost

    Apply a generous final layer of chocolate buttercream over the chilled crumb coat using an offset spatula. Smooth the top and sides; use a bench scraper for clean edges. Warm the spatula in hot water and dry between passes for a smoother finish if desired.

  3. 13

    Prepare chocolate shavings

    Hold a 4 oz semisweet chocolate bar at a slight angle and use a vegetable peeler to shave long curls or thin shavings. Alternatively, use a knife to create small shards. If you have pre-made chocolate curls, have 1/4 cup ready. Keep shavings at room temperature to avoid melting.

  4. 14

    Decorate the cake

    Gently press chocolate shavings and curls onto the top and upper sides of the frosted heart, arranging them densely along the top center for a delicate look. Dust lightly with 1 tsp unsweetened cocoa powder through a fine sieve for a soft matte finish. Add a few fresh berries or a pinch of edible glitter if using, placing them sparingly so the chocolate remains the focal point.

  5. 15

    Chill and serve

    Chill the finished cake in the refrigerator for 20–30 minutes to set the buttercream and help the shavings adhere. Remove from the fridge 20 minutes before serving to soften the buttercream for easier slicing. Serve at room temperature.
