Step 1: Prepare the Cake Batter

1. Preheat the oven to 350°F (175°C). Grease and line your heart-shaped cake pan (or two 8-inch round pans for manual shaping).
2. In a large mixing bowl, cream the softened butter and granulated sugar until light and fluffy.
3. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
4. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually mix the dry ingredients into the wet ingredients, alternating with the milk.
5. Add food coloring for a festive touch (4–5 drops of pink gel coloring recommended).

Step 2: Bake the Cake

1. Divide the batter evenly into prepared pans. Smooth the tops with a spatula.
2. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
3. Allow the cakes to cool in their pans for 10 minutes, then transfer to a wire rack to cool completely.

Step 3: Shape the Cake (if not using a heart pan)

1. Cut one round cake into a semicircle to form the bottom point of the heart.
2. Use the cut pieces to create the rounded top curves, securing them with a thin layer of frosting.
3. Trim any uneven edges to refine the shape.

Step 4: Apply the Crumb Coat

1. Spread a thin layer of buttercream frosting over the entire cake to lock in crumbs.
2. Chill the cake in the refrigerator for 20–30 minutes to set the crumb coat.

Step 5: Frost and Decorate

1. Prepare the buttercream by beating softened butter in a stand mixer until creamy. Gradually add powdered sugar, vanilla extract, and milk to achieve the desired consistency.
2. Apply the final layer of frosting, smoothing it with a spatula.
3. Use a piping bag with decorative tips to add borders, flowers, or other designs.
4. Decorate with fresh berries, edible glitter, or chocolate shavings for a dazzling finish.
